Description

Background Art

[0001] The present application generally relates to a system and method for processing a gas, such as a gaseous fuel or exhaust gas.

[0002] Industrial plants, such as power plants, may consume or generate a variety of gases, such as fuel gases (e.g., natural gas or syngas) and / or exhaust gases from combustion systems. Combustion systems may include gas turbine engines, reciprocating piston-cylinder engines, furnaces, boilers, or other industrial equipment. These gases may include one or more undesirable gases, such as acid gases and / or exhaust gases. For example, the undesirable gases may include hydrogen sulfide (H2S), carbon oxides (CO X ) such as carbon dioxide (CO2), nitrogen oxides (NO X ) such as nitrogen dioxide (NO2), and / or sulfur oxides (SO X ) such as sulfur dioxide (SO2). Therefore, it may be desirable to treat certain gases to remove undesirable gases from the gas stream, such as by removing undesirable gases from fuel gas upstream of a combustion system and / or removing undesirable gases from exhaust gas emitted by the combustion system. A gas treatment system may include a solvent-based absorption system that is configured to absorb the undesirable gases into a solvent that then flows through a solvent regeneration system to remove the undesirable gases. However, solvent-based absorption systems typically include a variety of equipment external to a conduit carrying the gas stream (e.g., a fuel supply conduit or an exhaust conduit), and therefore may increase the cost, complexity, and footprint of the solvent-based absorption system. Therefore, there is a need for a gas treatment system that is capable of continuous operation without reliance on a solvent-based absorption system. Summary of the invention

[0028] One or more specific embodiments of the presently disclosed system are described below. In order to provide a concise description of these embodiments, not all features of an actual implementation may be described in the specification. It should be understood that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as complying with system-related and business-related constraints, which may vary from implementation to implementation. In addition, it should be understood that such development work may be complex and time-consuming, but it is still a routine task of design, fabrication, and manufacturing for ordinary technicians who benefit from this disclosure.

[0029] When introducing elements of various embodiments of the presently disclosed embodiments, the articles "a," "an," "the," and "said" are intended to mean that there are one or more of the elements. The terms "comprising," "including," and "having" are intended to be inclusive and mean that there may be additional elements other than the listed elements.

[0030] The disclosed embodiments include a gas treatment system and method that enables gas treatment using multiple adsorption modules and a thermal control system that provides temperature control for multiple adsorption modules. As discussed below, the thermal control system is configured to provide direct heat exchange, indirect heat exchange, or a combination thereof to control the temperature of multiple adsorption modules, thereby facilitating the adsorption and desorption of undesirable gases. For example, a heat exchanger may be disposed upstream of multiple adsorption modules, directly at each adsorption module in a plurality of adsorption modules, or between consecutive adsorption modules to provide temperature control. The thermal control system may include one or more heat exchangers configured to operate as a heater or heating system, one or more heat exchangers configured to operate as a cooler or cooling system, or a combination thereof. In some embodiments, the heat exchanger may be disposed along a common heat transfer loop, and / or the heat exchanger may be arranged in a heat pump cycle or a refrigeration cycle.

[0031] In certain embodiments, the plurality of adsorption modules are configured to move back and forth between a first pipeline for adsorption of undesirable gas and a second pipeline for desorption of undesirable gas. The first pipeline and the second pipeline can be adjacent to each other and arranged along each other so that the adsorption module can move directly between the first pipeline and the second pipeline and inside the first pipeline and the second pipeline. The adsorption module can be configured to move linearly between the pipelines along a guide rail assembly, and the guide rail assembly can be oriented crosswise (e.g., vertically) with the longitudinal axis of the first pipeline and the second pipeline. The adsorption module may include one or more removable adsorbent boxes, which can be removed and replaced independently of each other. The adsorption module can also be accessed via an access door in the first pipeline and / or the second pipeline to perform inspection, overhaul, replacement or other maintenance procedures. The adsorption module can also move back and forth between the first pipeline and the second pipeline in a staggered manner so that one or more adsorption modules adsorb undesirable gas in the first pipeline, while one or more adsorption modules desorb undesirable gas in the second pipeline. Various aspects and embodiments of the gas treatment system are discussed in further detail below.

[0032] Figure 1 1 is a block diagram of an embodiment of a gas turbine system 10 having a gas turbine engine 12 coupled to a control system 14. As discussed in more detail below, the gas turbine system 10 may include a gas processing system 16 to process one or more gases in the gas turbine system 10. Various features of the gas processing system 16 are discussed in more detail below, and the various features may be used in any suitable combination with each other. However, before turning to the gas processing system 16, the gas turbine system 10 will be described as one possible scenario for using the gas processing system 16.

[0033] The gas turbine engine 12 includes an intake section 18, a compressor section 20, a combustor section 22, a turbine section 24, a load 26, and an exhaust section 28. The intake section 18 may include a duct having one or more muffler baffles, a fluid injection system (e.g., heating fluid injection for anti-icing), an air filter, or any combination thereof. The compressor section 20 may include an upstream inlet duct 30 having a bellmouth 32, wherein the inlet duct 30 includes an intake path located between an inner hub 34 and an outer wall 36. The inlet duct 30 also includes a stationary guide vane 38 and an inlet guide vane (IGV) 40. The inlet guide vane 40 may also be coupled to one or more actuators 42, which are communicatively coupled to the control system 14 and controlled by the control system 14.

[0034] The compressor section 20 includes one or more compressor stages 44, wherein each compressor stage 44 includes a plurality of compressor buckets 46 coupled to a compressor shaft 48 within a compressor housing 50, and a plurality of compressor vanes 52 coupled to the compressor housing 50. The compressor buckets 46 and the compressor vanes 52 are arranged circumferentially within each compressor stage 44 around a central axis of the compressor shaft 48. The compressor stages 44 may include between 1 and more than 30 compressor stages. In addition, the compressor stages 44 alternate between groups of compressor buckets 46 and groups of compressor vanes 52 in the direction of airflow through the compressor section 20. In operation, the compressor stages 44 progressively compress the incoming airflow before delivering it to the combustor section 22.

[0035] The combustor section 22 includes one or more combustors 54, each having one or more fuel nozzles 56. In certain embodiments, the combustor section 22 may have a single annular combustor 54 extending about the central axis of the gas turbine engine 12. However, in some embodiments, the combustor section 22 may include 2, 3, 4, 5, 6, or more combustors 54 circumferentially spaced about the central axis of the gas turbine engine 12. The fuel nozzles 56 receive compressed air 58 from the compressor section 20 and fuel 60 from one or more fuel supply systems 62, mix the fuel and air, and ignite the mixture to produce hot combustion gases 64, which then exit each combustor 54 and enter the turbine section 24.

[0036] The turbine section 24 includes one or more turbine stages 66, wherein each turbine stage 66 includes a plurality of turbine buckets 68 arranged circumferentially around and coupled to a turbine shaft 70 inside a turbine housing 72, and a plurality of turbine vanes 74 arranged circumferentially around the turbine shaft 70. The turbine stages 66 may include 1 to 10 or more turbine stages. In addition, the turbine stages 66 alternate between groups of turbine buckets 68 and groups of turbine vanes 74 in the direction of the flow of hot combustion gas through the turbine section 24. In operation, the hot combustion gases 64 gradually expand and drive the rotation of the turbine buckets 68 in the turbine stages 66.

[0037] The load 26 may include a generator, a machine, or some other driven load. The load 26 may be located at the hot end of the gas turbine engine 12, such as Figure 1 As shown, or the load 26 can be set at the cold end of the gas turbine engine 12 (e.g., adjacent to the compressor section 20). The exhaust section 28 may include an exhaust pipe, an exhaust treatment device, a muffler, or any combination thereof. In some embodiments, the exhaust section 28 may include and / or guide the exhaust flow through a heat exchanger and / or a cooling system. For example, the heat exchanger may include a heat recovery steam generator (HRSG) 27, which is configured to transfer heat from the exhaust to water, thereby generating steam to drive the steam turbine 29. For another example, the cooling system may include or exclude one or more coolers 31, such as a direct contact cooler configured to inject a fluid (e.g., a liquid such as water) directly into the exhaust for direct cooling of the exhaust (e.g., exhaust from the gas turbine engine 12 and / or the boiler 95). In some embodiments, the gas processing system 16 may include a dedicated heat exchanger (e.g., a heater and / or a cooler) to control the temperature, and thus the cooler 31 may be excluded from the gas turbine system 10. In certain embodiments, the gas turbine system 10 may include a combined cycle power plant having a gas turbine engine 12, a HRSG 27, and one or more steam turbines 29 driven by steam generated by the HRSG 27. Similar to the gas turbine engine 12, the steam turbines 29 may be configured to drive an electrical generator or other load.

[0038] The control system 14 may include one or more controllers 76, each having a processor 78, a memory 80, instructions 82 stored on the memory 80 and executable by the processor 78, and communication circuitry 84 configured to communicate with the gas processing system 16. The control system 14 is also coupled to various sensors(S) distributed throughout the gas turbine system 10 as indicated by element number 86. For example, the sensors 86 may be coupled to and monitor conditions at the intake section 18, the compressor section 20, the fuel supply system 62, the combustors 54 of the combustor section 22, the turbine section 24, the load 26, the exhaust section 28, and the gas processing system 16. The control system 14 is configured to receive feedback from the sensors 86 to facilitate adjusting various operating parameters of the gas turbine engine 12, such as intake air flow, fuel supply from the fuel supply system 62 to the combustor 54, operation of the exhaust treatment devices in the exhaust section 28, operation of the gas processing system 16 (e.g., movement of the adsorption module 100 to facilitate alternating cycles of adsorption and desorption), or any combination thereof. For example, the control system 14 can be configured to move the adsorption module 100 along a linear path between a first position in a first flow path in a first conduit and a second position in a second flow path in a second conduit, wherein the adsorption module 100 is configured to adsorb the undesirable gas when positioned at the first position in the first conduit and desorb the undesirable gas when positioned at the second position in the second conduit. In this manner, the adsorption module 100 can adsorb and desorb alternately, and the gas treatment system 16 can stagger the movement of different adsorption modules 100 to maintain at least one or more adsorption modules 100 in the first conduit for adsorption while at least one or more adsorption modules 100 are disposed in the second conduit for desorption.

[0039] As discussed in more detail below, the gas treatment system 16 is configured to remove and / or capture one or more undesirable gases (e.g., acid gases and / or exhaust gases) from the incoming gas in the adsorbent material in the adsorption module 100. Undesirable gases are intended to encompass any gas that may be undesirable in the fuel supply and / or exhaust. For example, undesirable gases may include acid gases present in the fuel supply and the exhaust. As another example, undesirable gases in the exhaust may include any exhaust gas that is typically regulated, including, but not limited to, carbon oxides (CO X ) such as carbon dioxide (CO2) and carbon monoxide (CO), nitrogen oxides (NO X ), sulfur oxides (SO X ) such as sulfur dioxide (SO2) or any combination thereof. The disclosed embodiments are particularly suitable for gas adsorption of CO2 from exhaust gases. However, when it comes to undesirable gases, the following discussion is intended to cover each of these examples.

[0040] The gas processing system 16 may be configured to receive the fluid 15 (e.g., purge gas, steam, etc.) from a fluid supply system 17, which may include one or more components or devices that generate steam or another suitable fluid (e.g., liquid, gas, or vapor) to desorb the undesired gas from the adsorption module 100. For example, the fluid supply system 17 may include a HRSG 27 and / or a steam turbine 29 that generates or outputs steam 96 as the fluid 15 for desorbing the undesired gas from the adsorption module 100. For another example, the fluid supply system 17 may include a boiler 95 (e.g., an independent or external boiler) configured to generate steam 96 from a heat source (e.g., combustion in the boiler 95), wherein the steam 96 may be used as the fluid 15 for desorbing the undesired gas from the adsorption module 100. As another example, the fluid supply system 17 may include one or more other fluid suppliers or devices configured to generate steam 96 or another fluid (e.g., purge gas, liquid, or vapor) to be used as the fluid 15 for desorbing the undesirable gas from the adsorption module 100. In certain embodiments, a vacuum system may be used independently and / or in combination with the fluid supply system 17 to facilitate desorbing the undesirable gas from the adsorption module 100. The vacuum system may include one or more vacuum pumps configured to reduce the pressure of the adsorption module 100 (e.g., reduce the pressure around the adsorbent material), thereby generating a pressure differential to help separate the undesirable gas (i.e., the gas adsorbed in the adsorbent material) from the adsorption module 100 and / or to extract the undesirable gas from the gas treatment system 16. Thus, the vacuum system is configured to suck or pull the undesirable gas out of the adsorption module 100. The vacuum system may be disposed at the respective adsorption module 100 and / or downstream of the adsorption module 100.

[0041] In operation, incoming gas (e.g., exhaust 94 from the turbine section 24, exhaust from the boiler 95, fuel from the fuel supply system 62, flue gas, etc.) flows through a first flow path in the gas treatment system 16, and one or more of the adsorption modules 100 adsorb undesirable gases from the incoming gas, while a fluid 15 (e.g., steam) flows through a second flow path in the gas treatment system 16 and desorbs undesirable gases from one or more of the adsorption modules 100. The gas exits the gas treatment system 16 as a treated gas 97 (e.g., treated exhaust, treated fuel, treated flue gas, etc.) lean in (or substantially free of) undesirable gases, and the fluid 15 exits the gas treatment system 16 as a fluid 98 rich in undesirable gases. The treated gas 97 may then flow through additional equipment. For example, if the treated gas 97 is treated exhaust or treated flue gas, the treated gas 97 may flow through an exhaust stack before being discharged into the environment. If the treated gas 97 is treated fuel gas, the treated gas 97 may then flow into the combustor section 22 of the gas turbine engine 12 .

[0042] The gas treatment system 16 may include a downstream device 99 located downstream of the adsorption module 100, such as a vacuum system, a fluid separation system, or any combination thereof. Similarly, the fluid 15 (e.g., steam) is used to desorb undesirable gases (e.g., CO2) from the adsorption module 100, and then further processed in the downstream device 99. The vacuum system of the downstream device 99 may include the above-mentioned equipment. The fluid separation system of the downstream device may include a flash tank, an absorber, or other equipment for separating the fluid 15 (e.g., steam) from the desorbed gas (e.g., undesirable gas). The gas treatment system 16 may use the downstream device 99 to separate and capture undesirable gases (e.g., CO2) from the fluid 15 (e.g., steam) so that the captured gas can be used for other applications. Therefore, the gas treatment system 16 can be described as a carbon capture adsorption system.

[0043] In operation, the gas turbine system 10 receives air from the intake section 18 into the inlet duct 30, as indicated by arrows 88, the inlet guide vanes 40 are controlled by the actuators 42 to adjust the angular position of the inlet guide vanes 40 to regulate the airflow into the compressor section 20, and the compressor section 20 is configured to compress the airflow supplied to the combustor section 22. For example, each stage 44 of the compressor section 20 compresses the airflow with a plurality of buckets 46. The compressed airflow 58 then enters each of the combustors 54, where the fuel nozzles 56 mix the compressed airflow with fuel 60 from the fuel supply system 62. The mixture of fuel and air then burns in each combustor 54 to produce hot combustion gases 64, which flow into the turbine section 24 to drive the rotation of the turbine buckets 68 in each stage 66. Rotation of turbine buckets 68 drives rotation of turbine shaft 70, which in turn drives rotation of load 26 and compressor section 20 via shaft 90 coupled to load 26 and shaft 92 coupled to compressor shaft 48. Turbine section 24 then discharges exhaust gas 94 into exhaust section 28 for final treatment and discharge to the environment.

[0044] In the illustrated embodiment, the gas turbine system 10 has a gas processing system 16 coupled to one or more fuel supply systems 62 and an exhaust section 28. However, the gas processing system 16 may also be coupled to one or more reciprocating piston cylinder engines, furnaces, boilers, chemical reactors, gasification systems having one or more gasifiers configured to produce syngas, or other industrial equipment. Each of these gas processing systems 16 has features described in further detail below, and the disclosed embodiments are intended to be used in various combinations with each other in all of the foregoing applications.

[0045] Figure 2 yes Figure 1104. A schematic diagram of an embodiment of a gas treatment system 16 further illustrates details of an adsorption module 100 that moves linearly back and forth between pipelines 102 and 104. As illustrated, the gas treatment system 16 includes an adsorption system 106 having a plurality of movable adsorption assemblies 108 that are configured to move the adsorption modules 100 between pipelines 102 and 104. For example, the adsorption system 106 can be configured to move the adsorption modules 100 in a staggered arrangement in pipelines 102 and 104, such that one or more of the adsorption modules 100 are positioned in pipeline 102 for adsorption of undesirable gases, and one or more of the adsorption modules 100 are positioned in pipeline 104 for desorption of undesirable gases. The adsorption modules 100 can be configured to move crosswise (e.g., perpendicularly) to the longitudinal axes of the pipelines 102 and 104, while also moving parallel to each other (e.g., along parallel travel paths in a linear direction). Various aspects of the adsorption module 100 are discussed in more detail below.

[0046] During normal operation of the gas treatment system 16, the adsorption module 100 may be completely disposed within the duct 102 and / or 104. The duct 102 has a flow path 110 extending longitudinally through the duct 102 between an inlet 112 and an outlet 114, wherein a sidewall 116 of the duct 102 extends around the flow path 110. For example, the sidewall 116 may include a rectangular sidewall that defines the rectangular shape of the duct 102. Similarly, the duct 104 has a flow path 118 extending longitudinally through the duct 104 from the inlet 120 to the outlet 122, wherein a sidewall 124 of the duct 104 extends around the flow path 118. For example, the sidewall 124 may define a rectangular sidewall 124 that defines the rectangular shape of the duct 104. The ducts 102 and 104 may be disposed directly adjacent to each other (e.g., in contact with each other) such that the ducts 102 and 104 have an intermediate wall 126 disposed directly between the flow path 110 of the duct 102 and the flow path 118 of the duct 104. In certain embodiments, the intermediate wall 126 can be a single shared wall between the pipes 102 and 104. However, in some embodiments, the intermediate wall 126 can include the sidewall 116 of the pipe 102 and the sidewall 124 of the pipe 104. Although the illustrated embodiments depict linear pipes 102 and 104, the pipes 102 and 104 can have one or more turns, curves, angled portions, or any combination thereof. In addition, the sizes of the pipes 102 and 104 can be the same or different from each other, and the pipes 102 and 104 can have the same or different shapes. The pipe 102 can also be described as an adsorption pipe (e.g., adsorbing undesirable gases into the adsorbent material of the adsorption module 100), while the pipe 104 can be described as a desorption pipe 104 (e.g., desorbing undesirable gases from the adsorbent material of the adsorption module 100). The pipes 102 and 104 can be configured to flow a variety of fluid streams (such as gas, liquid, or multiphase fluid streams).

[0047] In the illustrated embodiment, the conduit 102 is configured to receive and deliver a fluid stream 128, which may include fuel, exhaust gas, or another untreated gas with an undesirable gas. For example, the undesirable gas may include carbon oxides (CO X ) such as carbon dioxide (CO2) and carbon monoxide (CO), nitrogen oxides (NO X ), sulfur oxides (SO X) such as sulfur dioxide (SO2), hydrogen sulfide (H2S), or any combination thereof. The pipeline 104 is configured to receive and deliver a fluid stream 130, which may include steam, an inert gas (such as nitrogen, air, a vacuum, or a suction stream), or another fluid stream. As discussed in more detail below, each movable adsorption assembly 108 is configured to move a corresponding adsorption module 100 between a flow path 110 in the pipeline 102 and a flow path 118 in the pipeline 104 to alternately adsorb undesirable gases from the fluid stream 128 and desorb undesirable gases in response to heat added by the fluid stream 130 in the pipeline 104.

[0048] Each movable adsorption assembly 108 has an adsorption module 100 movably coupled to a linear positioning assembly 132 that extends between the adsorption modules 100 and enables the adsorption modules to move from the pipe 102 to the pipe 104 and from the pipe 104 to the pipe 102. The linear positioning assembly 132 may include a plurality of rail assemblies 134 coupled to the pipes 102 and 104 and the adsorption modules 100. In addition, the linear positioning assembly 132 includes a driver 136 coupled to a drive wire 138, wherein the drive wire 138 is coupled to the respective adsorption module 100.

[0049] As discussed in more detail below, each rail assembly 134 can include a mating set of rails 140 and one or more sliders 142 that are configured to move along the rails 140 between the pipes 102 and 104. For example, the sliders 142 can include wheels, blocks of low friction material, mating rails, or any combination thereof. In certain embodiments, the rails 140 are coupled to the pipes 102 and 104 and extend over all or substantially all of the distance between the sidewalls 116 and 124, while the sliders 142 are coupled to each of the adsorption modules 100. In the illustrated embodiment, the linear positioning assembly 132 has rail assemblies 134 disposed on opposite sides of each adsorption module 100. However, the rail assemblies 134 can be disposed along each respective adsorption module 100 at only one side, opposite sides, four corners, or any combination of locations.

[0050] A drive line 138 extends between the driver 136 and the adsorption module 100, wherein the drive line 138 may include a rigid rod or bar, a flexible cable, a chain, a rope, or any combination thereof. The driver 136 may include an electric motor, a fluid-driven piston cylinder assembly, an internal combustion engine, a gear assembly, a manual wheel or an actuator assembly, or any combination thereof. The drive line 138 may be configured to move linearly, rotate, or any combination thereof to cause the adsorption module 100 to move linearly between the pipe 102 and the pipe 104 along a linear travel path defined by the guide rail assembly 134 of the linear positioning assembly 132. The drive line 138 may also extend through the side wall 124, such as through an opening 144 in the side wall 124, wherein the drive line 138 may be further supported by a bushing or seal 146 at the side wall 124. For example, the bushing or seal 146 may be an annular structure that is configured to seal around the drive line 138 to prevent the fluid flow 130 from leaking from the pipe 104 into the surrounding environment. In some embodiments, the driver 136 can be disposed in a sealed housing along the sidewall 134 and / or the interior of the conduit 104 .

[0051] At each linear positioning assembly 132, the adsorption module 100 is configured to move between the pipes 102 and 104 via an opening 148 in the intermediate wall 126. For example, the opening 148 may have a size and shape that conforms to or is similar to the contour of the outer periphery 152 of the adsorption module 100. In addition, the opening 148 may be surrounded or defined by a seal 150. For example, as discussed in more detail below, the seal 150 may include a brush seal that always contacts the outer periphery 152 of the adsorption module 100 at the location of the adsorption module 100 when the adsorption module 100 moves between the pipe 102 and the pipe 104. Therefore, the interface between the seal 150 and the outer periphery 152 prevents leakage between the fluid flow 128 in the pipe 102 and the fluid flow 130 in the pipe 104. As shown in FIG. Figure 2 As illustrated, three of the linear positioning assemblies 132 have adsorption modules 100 disposed in the conduit 102 such that the adsorption modules 100 actively adsorb undesired gases from the fluid stream 128. However, three of the adsorption modules 100 are also disposed in the conduit 104 such that undesired gases may be desorbed from the adsorption modules 100 for regeneration prior to further use of the adsorption modules 100 in the conduit 102. As discussed in more detail below, the gas treatment system 16 is configured to alternate the positions of the adsorption modules 100 between the conduits 102 and 104 such that one or more of the adsorption modules 100 adsorb undesired gases in the conduit 102 while one or more of the adsorption modules 100 are regenerating by desorption in the conduit 104.

[0052] The controller 76 is configured to control the movement and positioning of the adsorption module 100 according to various parameters, such as the adsorption rate in the pipeline 102 and the desorption rate in the pipeline 104. Figure 2 As illustrated, in the pipeline 102, the fluid stream 128 processed by the adsorption module 100 results in the adsorption of the undesirable gas, so that the fluid stream 128 is processed and produces a processed fluid stream 154 that is discharged through the outlet 114 of the pipeline 102. For example, the processed fluid stream 154 may be completely or substantially free of undesirable gases, such as CO2, H2S, SO2, NO2, or any combination thereof. In the pipeline 104, the fluid stream 130 provides heat to facilitate the desorption of the undesirable gas from the adsorption module 100. For example, the fluid stream 130 may include steam that is configured to flow through and around each adsorption module 100 in the pipeline 104, thereby helping to heat the adsorption module 100 and desorb the undesirable gas from the adsorption module 100 for subsequent capture, cooling, and compression. Therefore, the pipeline 104 discharges a cooled fluid stream 156, such as cooled steam. In certain embodiments, the undesirable gas is desorbed from the adsorption module 100 into the conduit 104, which then carries the desorbed gas along with the cooled fluid stream 156 for subsequent capture, cooling, and compression. Alternatively or additionally, the desorbed gas may be separated and captured at each individual adsorption module 100.

[0053] The gas treatment system 16 may also include a thermal control system 101 having one or more temperature control systems, such as one or more coolers 158, one or more heaters 160, a cooling system 166, and a heating system 168. Each of the coolers 158, the heaters 160, the cooling system 166, and the heating system 168 may include an indirect heat exchanger, a direct heat exchanger, or a combination thereof. An indirect heat exchanger transfers heat between two fluids via separate flow paths so that the two fluids do not contact each other. A direct heat exchanger directly mixes the two fluids and enables contact between the two fluids, such as by injecting, spraying, or otherwise supplying the fluids into another flow path (e.g., water spray, steam spray, etc.). The thermal control system 101 is configured to provide heat transfer and thus temperature control at various locations upstream of the movable adsorption assembly 108 in the pipelines 102 and 104, directly at the movable adsorption assembly 108, between consecutive movable adsorption assemblies, or any combination thereof. In addition, the thermal control system 101 is configured to provide heat transfer between the pipes 102 and 104, such as by transferring heat between one or more heat exchangers in the pipe 102 and one or more heat exchangers in the pipe 104. Figure 2As shown, the cooler 158 and the heater 160 are disposed upstream of the movable adsorbent assembly 108; however, the cooler 158 and the heater 160 may also be disposed directly at the movable adsorbent assembly 108, disposed between consecutive movable adsorbent assemblies 108, and / or fluidly coupled together in a closed-loop heat transfer circuit between the conduits 102 and 104. Figure 2 As further illustrated in FIG. 1 , the cooling system 166 and the heating system 168 are disposed directly at the movable adsorbent assembly 108; however, the cooling system 166 and the heating system 168 may be disposed upstream of the movable adsorbent assembly 108, between consecutive movable adsorbent assemblies 108, and / or fluidly coupled together in a closed-loop heat transfer circuit between the conduits 102 and 104. Thus, each of the cooler 158, the heater 160, the cooling system 166, and the heating system 168 is contemplated for use in any or all of the aforementioned locations in the following discussion of the figures.

[0054] In the illustrated embodiment, the fluid stream 128 entering the pipeline 102 may be a heated fluid stream, such as exhaust gas. One or more coolers 158 may be disposed in the pipeline 102 upstream of the movable adsorption assembly 108. The cooler 158 is configured to cool the fluid stream 128 before it flows through the adsorption module 100 and / or flows around the adsorption module. In certain embodiments, if the fluid stream 128 is sufficiently cold or below a threshold temperature, the pipeline 102 may exclude the cooler 158 and / or the controller 76 may not operate the cooler 158. In addition, one of the cooling systems 166 may be coupled to each of the movable adsorption assemblies 108 to provide cooling directly at the corresponding movable adsorption assembly 108. The controller 76 may be configured to control each of the cooling systems 166 to provide a suitable temperature of the exhaust gas for adsorbing undesirable gases at the corresponding movable adsorption assembly 108. In certain embodiments, the controller 76 may be configured to activate the cooling system 166 for a particular movable adsorption assembly 108 only when the adsorption module 100 is disposed in the duct 104 for adsorption of undesirable gases from the exhaust gas, and then deactivate the cooling system 166 when the adsorption module 100 is disposed in the duct 102 for desorption of undesirable gases. In addition, the controller 76 may be configured to provide independent temperature control at each of the movable adsorption assemblies 108 (and specifically the adsorption modules 100) via the cooling system 166. The independent temperature control may be based on temperature feedback from the sensor 86 at each of the movable adsorption assemblies 108 (e.g., local temperature upstream of the adsorption module 100, downstream of the adsorption module, or directly at the adsorption module).

[0055] Similarly, in the pipeline 104, the fluid stream 130 may be heated by one or more heaters 160 to help raise the temperature of the fluid stream 130 before it passes through the adsorption module 100 being regenerated in the pipeline 104. For example, each heater 160 may be a resistive heater, a heat exchanger, or another form of heater configured to raise the temperature high enough to help induce desorption of the undesirable gas from the adsorption module 100. In certain embodiments, if the fluid stream 130 is sufficiently hot or above a threshold temperature, the pipeline 104 may exclude the heater 160 and / or the controller 76 may not operate the heater 160. In addition, one of the heating systems 168 may be coupled to each of the movable adsorption assemblies 108 to provide heating directly at the corresponding movable adsorption assembly 108. The controller 76 may be configured to control each of the heating systems 168 to provide a suitable temperature in the adsorbent material of the adsorption module 100 for desorption of the undesirable gas at the corresponding movable adsorption assembly 108. In certain embodiments, the controller 76 may be configured to activate the heating system 168 for a particular movable adsorption assembly 108 only when the adsorption module 100 is disposed in the duct 102 for desorbing undesirable gases, and then deactivate the heating system 168 when the adsorption module 100 is disposed in the duct 104 for adsorbing undesirable gases from the exhaust gas. In addition, the controller 76 may be configured to provide independent temperature control at each of the movable adsorption assemblies 108 (and specifically the adsorption modules 100) via the heating system 168. The independent temperature control may be based on temperature feedback from the sensor 86 at each of the movable adsorption assemblies 108 (e.g., local temperature upstream of the adsorption module 100, downstream of the adsorption module, or directly at the adsorption module).

[0056] The gas treatment system 16 may also include maintenance features to facilitate inspection, repair, overhaul, replacement, or otherwise modification of the adsorption modules 100 in each movable adsorption assembly 108. Thus, each of the movable adsorption assemblies 108 may include an access door 162 removably coupled to the sidewall 116 over an access opening 164 that is aligned with the linear positioning assembly 132 and the corresponding adsorption module 100. Thus, as discussed in more detail below, the access door 162 may be removed to allow visual inspection and / or removal of the adsorption module 100 through the access opening 164. The access door 162 may include a hinged door, a bolted door, a metal panel, a glass or other transparent panel to facilitate viewing, or any combination thereof.

[0057] As further illustrated, the control system 14 has a controller 76 coupled to each of the actuators 146 of the linear positioning assembly 132, each component of the thermal control system 101 (e.g., one or more coolers 158, one or more heaters 160, cooling system 166, and heating system 168), and a plurality of sensors 86 disposed throughout each of the conduits 102 and 104. As described above with reference to Figure 1 As discussed, each sensor is labeled S, and thus the sensors are not all numbered in the illustrated embodiment. However, each sensor 86 may be disposed upstream and / or downstream of each illustrated component, such as the adsorption module 100, the cooler 158, and the heater 160 in each pipeline 102 and 104. The sensor 86 may include a temperature sensor, a flow rate sensor, a pressure sensor, a fluid composition sensor, or any combination thereof. For example, the sensor 86 may include a gas composition sensor configured to monitor the adsorption rate of the undesirable gas from the adsorption module 100 disposed in the pipeline 102, and monitor the desorption rate of the undesirable gas from the adsorption module 100 disposed in the pipeline 104.

[0058] The adsorption or desorption rate of the undesirable gas may help facilitate the controller 76's control of the movement of the adsorption module 100 between the pipeline 102 and the pipeline 104. For example, if the adsorption rate gradually decreases to a level below a threshold adsorption rate, the controller 76 may be configured to operate the actuator 136 to move the adsorption module 100 from the pipeline 102 to the pipeline 104 so that the adsorption module 100 may undergo regeneration by desorbing the undesirable gas from the adsorption module 100 via the fluid stream 130. Similarly, if the desorption rate in the pipeline 104 gradually decreases to a level below a threshold desorption rate, the controller 76 may be configured to operate the actuator 136 to move the adsorption module 100 from the pipeline 104 to the pipeline 102 so that the adsorption module 100 may be used to adsorb the undesirable gas from the fluid stream 128 in the pipeline 102. Therefore, sensor feedback from the sensor 86 can facilitate control of the controller 76 to cycle the adsorption modules 100 back and forth between the pipelines 102 and 104, thereby ensuring that there are always one or more adsorption modules 100 in the pipeline 102 effectively adsorbing undesirable gases while other adsorption modules 100 are regenerating in the pipeline 104.

[0059] The controller 76 may also be configured to control the temperature in each of the pipes 102 and 104 via control of the cooler 158, the heater 160, the cooling system 166, and the heating system 168 of the thermal control system 101. For example, the controller 76 may be configured to control the cooler 158 and / or the cooling system 166 to adjust or maintain the temperature in the pipe 102 and / or the individual adsorption units 100 at or below a threshold temperature, while the controller 76 may be configured to control the heater 160 and / or the heating system 168 to adjust or maintain the temperature in the pipe 104 and / or the individual adsorption units 100 at or above a threshold temperature. Figures 3 to 20 Further details of the sorption module 100, the movable sorption assembly 108, the cooler 158, the heater 160, the cooling system 166, and the heating system 168 are discussed in greater detail.

[0060] Figure 3 is a schematic diagram of an embodiment of a temperature control system 170 (eg, an indirect heat exchange system) configured to Figure 2 The cooler 158, the heater 160, the cooling system 166 and / or the heating system 168 of the temperature control system 170 provide temperature control. For example, the temperature control system 170 may include a heat exchanger 172, a heat exchanger 174 and a fluid circuit 176 (heat exchange circuit) extending between the heat exchangers 172 and 174 and passing through them. For example, the fluid circuit 176 may include a plurality of coils or coiled tubes 178 in the heat exchanger 172 and a plurality of coils or coiled tubes 180 in the heat exchanger 174. The fluid circuit 176 may be configured to circulate a heat transfer fluid or a working fluid such as water, oil or lubricant, a refrigerant or any combination thereof. In certain embodiments, the temperature control system 170 may have heat exchangers 172 and 174 and a fluid circuit 176, which are arranged or configured as a heat pump cycle or a refrigeration cycle, such as a vapor compression cycle or a vapor absorption cycle. Therefore, the fluid circuit 176 may further include an expansion valve and a compressor to complete the heat pump cycle or the refrigeration cycle. The refrigerant may include, for example, R-32, HFC-32, or difluoromethane (CH2F2); R-134a, HFC-134a, or 1,1,1,2-tetrafluoroethane (CF3CH2F); R-410a, or pentafluoroethane (CF3CHF2); R-290, or propane (C3H8); R-600a, or isobutane (HC(CH3)3); R-717, or ammonia (NH3); R-744, or carbon dioxide (CO2); R-1234yf, HFO-1234yf, or 2,3,3,3-tetrafluoropropylene (C3H2F4); or any combination thereof.

[0061] In the illustrated embodiment, the temperature control system 170 can be configured to transfer heat between a relatively low temperature fluid stream 182 passing through the heat exchanger 172 and a relatively high temperature fluid stream 184 passing through the heat exchanger 174. The fluid circuit 176 circulates the working fluid through the coils or tubes 178 and 180 in the heat exchangers 172 and 174 so that heat can be transferred between the relatively low temperature and high temperature fluid streams 182 and 184. For example, the low temperature fluid stream 182 is configured to transfer heat away from the working fluid in the coils or tubes 178, while the high temperature fluid stream 184 is configured to transfer heat to the working fluid in the coils or tubes 180. Therefore, the heat exchanger 172 can also be described as a heater because the heated working fluid passing through the coils or tubes 178 causes the temperature of the low temperature fluid stream 182 to increase. The heat exchanger 174 can be described as a cooler because the relatively cool working fluid in the coils or tubes 180 is configured to cool or reduce the temperature of the high temperature fluid stream 184. In certain embodiments, the temperature control system 170 may be configured as a heat pump, wherein the heat exchanger 172 is a condenser configured to cool and condense the working fluid in the fluid loop 176 and heat the fluid stream 182, and the heat exchanger 174 is an evaporator configured to heat and evaporate the working fluid in the fluid loop 176 and cool the fluid stream 184. In the aforementioned embodiments (e.g., heat pump), the fluid loop 176 may further include an expansion valve located downstream of the heat exchanger 172 (e.g., condenser) and upstream of the heat exchanger 174 (e.g., evaporator), and the fluid loop 176 may include a compressor located downstream of the heat exchanger 174 (e.g., evaporator) and upstream of the heat exchanger 172 (e.g., condenser).

[0062] In certain embodiments, the temperature control system 170 may be disposed in the gas treatment system 16 in a variety of ways. For example, the heat exchanger 172 may correspond to the heater 160, while the heat exchanger 174 corresponds to the cooler 158, such that the entire temperature control system 170 is disposed within the pipes 102 and 104. Alternatively or additionally, the heat exchanger 172 may be disposed in the pipe 104 as the heater 160, while the heat exchanger 174 is disposed outside the gas treatment system 16 in the path of a completely different, higher temperature fluid stream 184. Similarly, the heat exchanger 174 may be disposed in the pipe 102 and serve as the cooler 158, while the heat exchanger 172 may be disposed completely outside the gas treatment system 16 in a lower temperature fluid stream 182 separate from the gas treatment system 16. However, the various aforementioned configurations may be used alone or in combination with each other, as well as in combination with other types of coolers 158 and heaters 160.

[0063] In certain embodiments, the temperature control system 170 may use heat exchangers 172 and 174 associated with the cooling system 166 and the heating system 168. For example, the heat exchanger 172 may correspond to the heating system 168, while the heat exchanger 174 corresponds to the cooling system 166, such that the entire temperature control system 170 is disposed at one or more of the movable adsorption assemblies 108 within the pipelines 102 and 104. Alternatively or in addition, the heat exchanger 172 may be disposed in the pipeline 104 as the heating system 168, while the heat exchanger 174 is disposed outside the gas treatment system 16 in the path of a completely different, higher temperature fluid stream 184. Similarly, the heat exchanger 174 may be disposed in the pipeline 102 and used as the cooling system 166, while the heat exchanger 172 may be disposed completely outside the gas treatment system 16 in a lower temperature fluid stream 182 separate from the gas treatment system 16.

[0064] Figure 41 is a schematic diagram of an embodiment of a direct heat exchange system 190 that is configured to provide heating or cooling depending on the configuration of the system 190. For example, the illustrated direct heat exchange system 190 includes a fluid supply 192, a fluid distribution manifold 194, and a conduit 196 extending between the fluid supply 192 and the distribution manifold 194. The fluid conduit 196 may also include one or more flow control components, such as a fluid pump 198 and a fluid control valve 200. The fluid pump 198 is configured to pump a fluid flow from the fluid supply 192, while the fluid control valve 200 is movable between open and closed valve positions to adjust the flow rate of the fluid flow from the fluid supply 192. The fluid pump 198 and the fluid control valve 200 are collectively configured to control the flow of fluid from the fluid supply 192 to the fluid distribution manifold 194. The fluid distribution manifold 194 may also include a plurality of fluid nozzles 202 that are configured to output a spray 204 of fluid from the fluid supply 192. For example, the fluid supplier 192 may include a liquid or gas at a desired temperature to provide heating or cooling directly in the fluid stream 128 or the fluid stream 130 of the gas treatment system 16. Thus, the direct heat exchange system 190 may be configured as a cooler 158 and / or a cooling system 166 by injecting a relatively low temperature fluid into the fluid stream 128. Similarly, the direct heat exchanger system 190 may be configured as a heater 160 and / or a heating system 168 by injecting a relatively high temperature fluid stream into the fluid stream 130. The fluid supplier 192 may include water, an inert gas (such as nitrogen), air, steam, or another suitable gas or liquid. In certain embodiments, the injection location may be disposed upstream of the movable adsorption assembly 108 having the adsorption module 100, directly at the movable adsorption assembly 108 having the adsorption module 100, between consecutive movable adsorption assemblies 108 having the adsorption module 100, or any combination thereof. In addition, the direct heat exchange system 190 may be used alone or in combination with the movable adsorption assembly 108. Figure 3 The temperature control system 170 (eg, an indirect heat exchange system) is used in combination with various components of the thermal control system 101 , as discussed in more detail below.

[0065] Figure 5 yes Figure 1 and Figure 2100 is a perspective view of an embodiment of an adsorption module 100. As illustrated, the adsorption module 100 includes an adsorbent cartridge 210 disposed in a frame 212. The frame 212 includes side walls 214, 216, 218, and 220, which may collectively define a rectangular panel structure of the frame 212. For example, the side walls 214 and 216 may be flat rectangular panels parallel to each other, while the side walls 218 and 220 may be flat rectangular panels parallel to each other and perpendicular to the side walls 214 and 216. The side walls 214 and 216 or the side walls 218 and 220 may also be coupled to the slider 142 of the rail assembly 134, as described above with reference to Figure 2 discussed.

[0066] The adsorbent cartridge 210 may include an adsorbent material 212 surrounded and contained by a screen 224. The adsorbent material 212 may include a plurality of adsorbent particles, beads, spheres, strips, or discrete elements of the same or different sizes and shapes. The screen 224 may have a wire mesh with sufficiently small openings to hold the adsorbent material 212 while enabling fluid to flow along the flow paths 110 and 118. In certain embodiments, the screen 224 extends along the opposite upstream side 226 and downstream side 228 of the adsorbent cartridge 210, around the lateral sides 230, 232, 234, and 236, or any combination thereof. Thus, the screen 224 enables the fluid stream 128 or the fluid stream 130 to flow relatively freely through the adsorbent material 222 held in place by the screen 224. In some embodiments, the screen 224 may be disposed only along the upstream side 226 and the downstream side 228 , while solid sidewalls may be disposed along the lateral sides 230 , 232 , 234 , and 236 of the sorbent cartridge 210 .

[0067] Additionally, in certain embodiments, the sorbent cartridge 210 may be removable from the frame 212 for replacement or servicing as needed during operation of the gas treatment system 16. For example, the sorbent cartridge 210 may be removable from the upstream side 226 and / or the downstream side 228 of the frame 212. Figure 5 The embodiment of the sorption module 100 shows one sorbent cartridge 210 , but embodiments of the sorption module 100 may include any number and configuration of sorbent cartridges 210 that may be removably disposed within a frame 212 .

[0068] Figure 6 is a perspective view of an embodiment of an adsorption module 100 having a plurality of adsorbent cartridges 210 disposed within a frame 212. The features of the adsorbent cartridges 210 are substantially the same as described above with reference to Figure 5 Same as discussed. However, Figure 6The embodiment has a plurality of smaller adsorbent cartridges 210 arranged in rows 240, 242, and 244 and columns 246 and 248. Column 248 is disposed along the upstream side 226, and column 248 is disposed along the downstream side 228. The sizes and configurations of the illustrated adsorbent cartridges 210 may be substantially identical to one another. However, in some embodiments, the adsorption module 100 may have a plurality of adsorbent cartridges 210 of different sizes and configurations, which may include different sizes, different adsorbent materials 222, different screen arrangements of the screen 224, or any combination thereof. As illustrated, the adsorption module 100 has three rows 240, 242, and 244; however, the adsorption module 100 may have any number of rows (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more rows). Similarly, the illustrated sorption module 100 has two columns 246 and 248; however, the sorption module 100 may have any number of columns (eg, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more columns).

[0069] In the illustrated embodiment, the frame 212 includes a plurality of cartridge openings 250 disposed in the side wall 214, such that each of the adsorbent cartridges 210 can be inserted and removed through one of the cartridge openings 250 of the frame 212. Thus, the adsorption module 100 includes the cartridge openings 250 to facilitate easy inspection, repair, replacement, and other maintenance actions on each of the adsorbent cartridges 210 independently of one another. Figure 5 and Figure 6 The adsorption module 100 may be configured to be inserted and removed through the access opening 164 of the conduit 102, as described above with reference to Figure 2 discussed.

[0070] Figure 7 Yes Figure 2 A partial schematic diagram of an embodiment of a movable adsorption assembly in the illustrated movable adsorption assembly 108. In the illustrated embodiment, the movable adsorption assembly 108 has an adsorption module 100 that is slidably disposed along a linear positioning assembly 132 via a guide rail assembly 134 disposed on opposite sides 260 and 262 of the adsorption module 100. For example, each side 260 and 262 of the adsorption module 100 may have one or more sliders 142 that are configured to slide or move along a corresponding guide rail 140 in a linear direction (e.g., a linear travel path) as indicated by arrows 264. The opposite sides 260 and 262 may correspond to the above reference Figure 5 and Figure 6Any of the opposite sides discussed. For example, the opposite sides 260 and 262 may correspond to the upstream side 226 and the downstream side 228 of the frame 212, the sidewalls 214 and 216, or the sidewalls 218 and 220. In some embodiments, each of the opposite sides 260 and 262 of the adsorption module 100 may have multiple guide rail assemblies 134, such as guide rail assemblies 134 disposed along the corners or edges of the opposite sides 260 and 262, at one or more intermediate locations along each side 260 and 262, or a combination thereof. The illustrated guide rail assembly 134 has three sliders 142 disposed in each guide rail 140 on each side 260 and 262. However, certain embodiments of the guide rail assembly 134 may include 2, 3, 4, 5, 6, 7, 8, 9, 10, or more sliders 142 disposed in each of the guide rails 140.

[0071] The slider 142 may include a rotatable wheel, a low friction material block, or a combination thereof. For example, the low friction material block may include a low friction metal or metal coating, a low friction plastic or plastic coating, a low friction ceramic or ceramic coating, nylon, polytetrafluoroethylene (PTFE), a diamond-like carbon (DLC) coating, or any combination thereof. The slider 142 may also be partially or completely constrained within each rail 140 so that the slider 142 does not fall off the rail 140 when the adsorption module 100 is moved in the linear direction 264. In addition, as discussed above, the rail 140 typically extends over the entire distance across each of the pipes 102 and 104, so that the rail assembly 134 enables the adsorption module 100 to be fully moved into one of the pipes 102 or 104. Other details of the rail assembly 134 are discussed in more detail below.

[0072] Figure 8 yes Figure 2 and Figure 7 140 is a partial cross-sectional view of an embodiment of a guide rail assembly 134, further illustrating details of the engagement between the guide rail 140 and the slider 142. As illustrated, the guide rail 140 may include a C-shaped section 270 having an upper wall 272 and a lower wall 274 coupled together via a side wall 276. For example, the upper wall 272 may include a plate 278 having a radially inward lip 280, and the lower wall 274 may have a plate 282 with a radially inward lip 284. For example, the plates 278 and 282 may be substantially parallel to each other, and the radially inward lips 280 and 284 may protrude inwardly toward each other around the internal channel 286. The side wall 276 may also include a plate 288 coupled to the plates 278 and 282. The C-shaped section 270 may be as shown in FIG. Figure 7The linear direction 264 shown extends linearly so that the slider 142 can move along the internal channel 286 between the plate 278 of the upper wall 272 and the 282 of the lower wall 274. In addition, the radially inward lips 280 and 284 are configured to prevent the slider 142 from accidentally moving out of the C-section 270 of the guide rail 140.

[0073] As discussed above, the slider 142 can be constructed as a rigid low-friction sliding material, a rotatable wheel, or a combination thereof. In the illustrated embodiment, the slider 142 has a wheel 290 rotatably coupled to an axis 292, which in turn is coupled to the frame 212 of the adsorption module 100 via the mounting member 292. The wheel 290 may also include a bearing 296 disposed around the axis 292 to help facilitate the rotation of the wheel 290 around the axis 292. The mounting member 294 can be configured to be fixedly or removably coupled to the frame 212. For example, the mounting member 294 can be welded to the frame 212 via one or more welded joints 298. In some embodiments, the wheel 290 can be a block of low-friction material that facilitates sliding along the guide rail 140, such as a low-friction metal, plastic, ceramic, or other suitable material.

[0074] Fig. 9 yes Figure 2 108, further illustrating details of a seal 150 disposed around an opening 148 in the intermediate wall 126 between the first duct 102 and the second duct 104. The opening 148 and the seal 150 facilitate movement of the adsorption module 100 between the ducts 102 and 104, as described above with reference to Figure 2 As illustrated, the opening 142 is a rectangular shaped opening that conforms to the rectangular shape of the adsorption module 100. A seal 150 is disposed around the perimeter of the opening 148.

[0075] In certain embodiments, the seal 150 may include a sealing frame or border 310 disposed around the opening 148, and a flexible sealing material 312 disposed along the sealing frame or border 310. For example, the sealing frame or border 310 may have a rectangular shape that conforms to or matches the rectangular shape of the opening 148, and the flexible sealing material 312 may include a flexible metal, plastic, rubber, or other material depending on the temperature of the fluid stream 128 and the fluid stream 130. For example, in certain embodiments, the flexible sealing material 312 may include a plurality of fibers 314 of a brush seal 316. Thus, the brush seal 316 may include a plurality of closely spaced fibers 314 made of the flexible sealing material 312 to facilitate a dynamic seal as the adsorption module 100 moves through the opening 148 between the duct 102 and the duct 104.

[0076] Regardless of the position of the adsorption module 100, the seal 150 is configured to maintain a seal along the frame 212 of the adsorption module 100 to help prevent leakage of the fluid flows 128 and 130 between the pipes 102 and 104. In some embodiments, the seal 150 may include a variety of different types of seals, such as a brush seal 316 with fibers 314, a metal seal, a plastic seal, a rubber seal, a fabric seal, or any combination thereof. The seal 150 may include a single continuous strip of flexible sealing material 312, discrete pieces of flexible sealing material 312 (e.g., fibers 314 of a brush seal 316), overlapping flaps of flexible sealing material 312, or any combination thereof.

[0077] Fig.10 is along Fig. 9 A partial cross-sectional view of the movable adsorption assembly 108 taken along line 10-10 of , further illustrates the adsorption module 100 sealed against the seal 150 within the opening 148 of the intermediate wall 126. As illustrated, the seal 150 has fibers 314 of a brush seal 316 disposed against and in contact with the frame 212 of the adsorption module 100. The fibers 314 are coupled to and supported by a sealing frame or border 310 that includes an edge wall 320 and opposing side walls 322. The edge wall 320 is configured to extend along an inner edge 324 of the opening 148, while the side walls 322 are configured to extend along opposing side surfaces 326 of the intermediate wall 126. The edge wall 320 and the opposing side walls 322 together define a C-shaped structure 328 that is configured to be self-retaining around the intermediate wall 126 at the opening 148. However, in certain embodiments, the C-shaped structure 328 of the sealing frame or frame 310 can be further coupled to the intermediate wall 126 via a fixed joint, a removable fastener, or a combination thereof. For example, the fixed joint can include a welded joint, a brazed joint, or an integrally formed structure. The removable fastener can include a bolt, a clamp, a spring or a hook, a dovetail joint, or any combination thereof.

[0078] Likewise, the illustrated seal 150 has fibers 314 of a brush seal 316 coupled to a sealing frame or border 310. As illustrated, the fibers 314 are directly connected to the edge wall 320. When the adsorption module 100 moves between the duct 102 and the duct 104 along the linear positioning assembly 132, the fibers 314 of the brush seal 316 are configured to provide a seal between the intermediate wall 126 and the adsorption module 100. In other embodiments, the fibers 314 can be replaced or supplemented with other sealing components, such as flexible flaps, flexible washers, or any combination thereof. These flexible flaps or washers can be made of flexible metal, plastic, or other materials.

[0079] Fig.11 yes Figure 21 is a schematic diagram of an embodiment of a movable adsorption assembly 108, further showing details of an access door 162 disposed above an access opening 164 in a side wall 116 of a duct 102 to enable insertion and removal of the adsorption module 100. In the illustrated embodiment, the access door 162 is a rectangular panel disposed above the access opening 164, which may also be a rectangular access opening. The access door 162 is removably coupled to the side wall 116 of the duct 102 via a plurality of fasteners 340. For example, the fasteners 340 may include threaded bolts, threaded nuts, threaded shafts, clips, clamps, rotatable latches, hinges, or any combination thereof. The details of the fasteners 340 will be discussed in more detail below. The fasteners 340 are disposed around a frame or flange 342 of the access door 162, wherein the frame or flange 342 extends outside the access opening 164 or overlaps a portion of the side wall 116 outside the access opening. Fasteners 340 may be loosened, removed, or adjusted to allow access door 162 to be removed or moved away from access opening 164, thereby enabling Figure 2 The sorption module 100 is inspected, inserted or removed relative to the interior of the pipe 102 as shown in FIG.

[0080] Fig.12 yes Figure 2 16, further illustrating details of the adsorption module 100 partially removed and protruding from the sidewall 116 of the pipeline 102 via the access opening 164. As illustrated, the access door 162 is removed from the access opening 164, thereby exposing the access opening 164 and enabling removal of the adsorption module 100. The fastener 340 may include a plurality of threaded shafts 350 coupled to the sidewall 116, and the access door 162 includes a plurality of shaft openings 352 to receive the threaded shafts 350. The fastener 340 may also include a plurality of threaded nuts 354 configured to couple with the threaded shafts 350 on the exterior of the access door 162, thereby removably securing the access door 162 to the sidewall 116. In the illustrated embodiment, the access door 162 and the threaded nuts 354 are removed from the pipeline 102, thereby allowing access to and removal of the adsorption module 100 from the pipeline 102.

[0081] The linear positioning assembly 132 enables the adsorption module 100 to be linearly slid out of the duct 102 as shown by arrow 356, while the cartridge opening 250 in the frame 212 of the adsorption module 100 enables each adsorbent cartridge 210 to be inserted and removed as shown by arrow 358. For example, each adsorption module in the adsorption module 100 can be inserted and removed via the following method: Figure 2 The respective access doors 162 and access openings 164 illustrated are accessed independently, and the remaining adsorption modules 100 may continue to operate in either the duct 102 or the duct 104. Fig.12As illustrated, when one of the adsorption modules 100 is inspected, removed, installed, or replaced, one or more adsorbent cartridges 210 may also be independently accessed and moved via the cartridge opening 250. For example, each of the adsorbent cartridges 210 may be linearly removed from the cartridge opening 250, inspected, replaced, and reinstalled into the corresponding cartridge opening 250. Fig.12 As further illustrated in FIG. 1 , each of the rail assemblies 134 may include a rail extension 360 configured to extend outwardly from the sidewall 116 when the adsorption module 100 is withdrawn from the duct 102. When the adsorption module 100 is installed back into the duct 102, the rail extension 360 may slide back into the interior of the duct 102.

[0082] Fig.13 Yes Fig.12 A partial cross-sectional view of an illustrated embodiment of an access door 162 coupled to the sidewall 116 of the duct 102 at the access opening 164. In the illustrated embodiment, a threaded shaft 350 protrudes outwardly from the sidewall 116, the access door 162 is disposed about the threaded shaft 350 via the shaft opening 352, and a threaded nut 354 is threaded onto the threaded shaft 350 to compressively secure the access door 162 to the sidewall 116. In the illustrated embodiment, the access door 162 may be sealed relative to the sidewall 116 via a flat seal or gasket 370 disposed between the access door 162 and the sidewall 116. Additionally, the threaded nut 354 may be secured to the threaded shaft 350 with an intermediate gasket 372 (e.g., a locking gasket) between the threaded nut 354 and the access door 162. For example, the gasket 372 may be a tapered gasket or Belleville gasket, a wave gasket, a split or spring lock gasket, a tooth lock gasket, or any combination thereof.

[0083] Fig.14 It is used to process Figure 1Flow chart of an embodiment of a process 380 for treating a gas in a system of a gas treatment system 10 of a gas treatment system 10 of the present invention. The gas treatment may correspond to fuel gas treatment, exhaust gas treatment, or other gas treatment to remove one or more undesirable gases, as discussed in detail above. For example, the undesirable gas may include CO2, H2S, SO2, NO2, or any combination thereof. In the illustrated embodiment, the process 380 may include adsorbing gas from the first fluid stream 128 in the first conduit 102 into the adsorption module 100 to produce a treated first fluid stream 154, as shown in box 382. The adsorption may include adsorption into one or more adsorbent cartridges 210 of the adsorption module 100, as discussed in detail above. The process 380 may then continue to monitor one or more parameters related to the adsorption of the gas by the adsorption module 100, as shown in box 384. For example, the process 380 may monitor various sensors 86 disposed throughout the gas treatment system 16, such as monitoring temperature, pressure, flow rate, gas composition of the undesirable gas, rate of change of adsorption, or any combination thereof. The process 380 may then continue to compare the parameter with one or more threshold values, as shown in box 386. For example, the process 380 may include comparing the adsorption rate to a threshold adsorption rate. The threshold adsorption rate may indicate that the adsorption module 100 needs to be regenerated to remove the undesirable gas adsorbed into the adsorbent material 222 of the adsorbent cartridge 210.

[0084] Then, when the parameter satisfies the threshold, the process 380 may proceed to move the adsorption module 100 from the first conduit 102 to the second conduit 104, as shown in block 388. Thus, the movable adsorption assembly 108 facilitates movement between the first conduit 102 and the second conduit 104, such as by moving the adsorption module 100 along the track assembly 134 of the linear positioning assembly 132. In particular, the process 380 moves the adsorption module 100 along a linear travel path defined by the track assembly 134 (such as perpendicular to the longitudinal axes of the conduits 102 and 104).

[0085] The process 380 may then proceed to desorb the gas from the adsorption module 100 via the second fluid stream 130 in the second conduit 104 to regenerate the adsorption module 100, as shown in block 390. As discussed above, regeneration in the second conduit 104 may include flowing a heated fluid, such as steam, through and / or around the adsorption module 100 to increase the temperature of the adsorbent material 222 and to assist in desorbing the undesirable gas from the adsorbent cartridge 210 into the fluid stream 130. The process 380 may then proceed to capture, cool, and compress the gas desorbed from the adsorption module 100, as shown in block 392. The undesirable gas desorbed from the adsorption module 100 may be captured directly at each respective adsorption module 100, in a subsequent process downstream of the adsorption module 100, or by another technique. Cooling may also facilitate separation of the fluid stream 130 from the desorbed gas, such as by condensing the steam stream to allow the desorbed gas to separate in the conduit 104. Additionally, the captured gas may be passed through one or more heat exchangers, compressors, or other processing systems before being sent to storage or a pipeline.

[0086] The process 380 may also monitor one or more parameters related to desorbing gas from the adsorption module 100, as shown in block 394. For example, the process 380 may monitor the temperature, flow rate, gas composition, or desorption rate of the gas from the adsorption module 100. The process 380 may then compare the one or more parameters to corresponding thresholds, as indicated in block 396. The comparison in block 396 may include comparing the desorption rate to a threshold desorption rate, such that when the parameter meets the threshold, a sufficiently low desorption rate may trigger the process 380 to move the adsorption module 100 from the second conduit 104 to the first conduit 102, as shown in block 398. The process 380 may then repeat the process, as indicated in block 400. Thus, the process 380 may repeatedly cycle or move the adsorption module 100 back and forth between the conduit 102 and the conduit 104, thereby enabling adsorption of undesirable gas into the adsorption module 100 in the conduit 102 and enabling desorption of undesirable gas from the adsorption module 100 in the conduit 104.

[0087] Fig.15 yes Figures 1 to 14 A schematic diagram of an embodiment of a gas processing system further showing a gas processing system having a Figure 2 Details of the thermal control system 101 are discussed with respect to the cooling system 166 and the heating system 168. The exemplary gas processing system 16 has Figure 2 The adsorption system 106, wherein one of the movable adsorption components 108 is illustrated for simplicity. However, Fig.15 The adsorption system 106 may include any number (e.g., 1 to 10 or more) of movable adsorption components 108, such as Figure 2The six movable adsorption components 108 are shown. Fig.15 The illustrated embodiments are intended only to illustrate details of one of the movable adsorption assemblies 108 , and in particular aspects of the thermal control system 101 . Fig.15 The illustrated features of may be part of the gas treatment system 16 of all other figures and embodiments described herein.

[0088] The cooling system 166 may include a cooling supply system 410 coupled to a heat exchanger 412 disposed in the conduit 102 of an adsorption unit 414 of the adsorption system 106. Similarly, the heating system 168 may include a heating supply system 416 coupled to a heat exchanger 418 disposed in the conduit 104 of a desorption unit 420 of the adsorption system 106. The illustrated heat exchangers 412 and 418 are separated from each other, such as by an intermediate wall 126 disposed between the conduits 102 and 104 of the respective adsorption unit 414 and desorption unit 420. The thermal control system 101 may also include a heat exchange system 422 having a heat exchanger 424 disposed in the conduit 102 of the adsorption unit 414 and a heat exchanger 426 disposed in the conduit 104 of the desorption unit 420. The heat exchange system 422 is configured to exchange heat between the conduits 102 of the adsorption unit 414 and the conduits 104 of the desorption unit 420 via heat exchange between the heat exchangers 424 and 426, as discussed below. Independently or in conjunction with one another, the heat exchangers 412 and 424 are configured to provide cooling to the exhaust gas 94 flowing through the conduits 102 of the adsorption unit 414 and / or to the adsorption module 100, while the heat exchangers 418 and 426 are configured to provide heating in the conduits 104 of the desorption unit 420 and / or to the adsorption module 100. In certain embodiments, the heat exchangers 412 and 424 are integrated together as a combined or shared heat exchanger, while the heat exchangers 418 and 426 are integrated together as a combined or shared heat exchanger. The cooling provided in the conduit 102 of the adsorption unit 414 and / or in the adsorption module 100 (i.e., when disposed in the conduit 102) is configured to assist in the adsorption of the undesired gas from the exhaust gas 94 by adjusting the temperature to within a suitable temperature range for the adsorption process. Similarly, the heating provided in the conduit 104 of the desorption unit 420 and / or in the adsorption module 100 is configured to assist in the desorption of the undesired gas from the adsorption module 100 (i.e., when disposed in the conduit 104) by adjusting the temperature to within a suitable temperature range for the desorption process.

[0089] The cooling supply system 410 is coupled to one or more cooling circuits 428 disposed within a shell or body 430 of the heat exchanger 412 within the conduits 102 of the adsorption unit 414. The cooling circuit 428 may include a fluid flow channel (e.g., a series of chambers, channels, or other hollow spaces) defining one or more flow paths throughout the shell or body 430, one or more conduits or tubes extending along a flow path throughout the shell or body 430, or a combination thereof. The cooling circuit 428 may include a coiled flow path, a winding flow path, a spiral or helical flow path, a helical flow path, a tortuous flow path, or any combination thereof. The cooling circuit 428 is coupled to the manifold 432 of the heat exchanger 412 at an inlet 434 and an outlet 436. In certain embodiments, the housing or body 430 may include a U-shaped structure 438 having a module receptacle or chamber 440 surrounded by two opposing sides 442 and 444 (e.g., an upstream side and a downstream side) and a side 446 (e.g., a lateral side) adjacent to the manifold 432. The chamber 440 is configured to receive the adsorption module 100 when disposed in the adsorption unit 414. Thus, the U-shaped structure 438 has a cooling circuit 428 extending along the sides 442, 444, and 446, thereby providing cooling along at least three sides of the chamber 440 and the adsorption module 100.

[0090] The cooling system 166 is configured to circulate a cooling fluid 448 from the coolant supply system 410 into the inlet 434 of the manifold 432, through the cooling circuit 428, and out through the outlet 436 of the manifold 432 back to the cooling supply system 410. In certain embodiments, the cooling supply system 410 receives the cooling fluid 448 that is already in a cooled state within a suitable temperature range, so that no cooler or heat exchanger in the cooling supply system 410 performs additional temperature regulation. For example, the cooling supply system 410 may receive the cooling fluid 448 from another cooled fluid source in the gas turbine system 10, such as cooled water from a cooling tower. However, in certain embodiments, the cooling supply system 410 receives the cooling fluid 448 at a temperature outside the desired temperature range, and thus the cooling supply system 410 may perform additional temperature control (e.g., cooling and / or heating) on ​​the cooling fluid 448 to regulate the temperature within the suitable temperature range. For example, the cooling fluid 448 may be cooled by one or more additional coolers or heat exchangers of the cooling supply system 410 , or the cooling fluid 448 may be heated by one or more additional heaters or heat exchangers of the cooling supply system 410 .

[0091] Thus, the cooling supply system 410 may include a single heat exchange or single fluid system 450 and / or multiple heat exchange or multiple fluid systems 452 configured to supply a cooling fluid 448 at a suitable temperature range for circulation and cooling through the cooling circuit 428. In other words, the cooling fluid 448 may be the only cooling fluid (e.g., a liquid coolant such as water) used by the single fluid system 450, while the cooling fluid 448 (e.g., a liquid coolant such as water) may be cooled by another cooling fluid (e.g., a liquid or gas) in the multiple fluid system 452. In certain embodiments, the cooling supply system 410 includes one or more pumps, valves, pressure regulators, sensors, filters (e.g., particulate filters, separators, etc.), processing units (e.g., chemical processing units, ultraviolet light processing units, etc.), or any combination thereof, configured to control various parameters and quality of the cooling fluid 448 supplied to the heat exchanger 412.

[0092] The heating supply system 416 is coupled to one or more heating loops 460 disposed within the shell or body 462 of the heat exchanger 418 within the conduit 104 of the desorption unit 420. The heating loop 460 may include a fluid flow channel (e.g., a series of chambers, channels, or other hollow spaces) defining one or more flow paths throughout the shell or body 462, one or more conduits or tubes extending along a flow path throughout the shell or body 462, or a combination thereof. The heating loop 460 may include a coiled flow path, a winding flow path, a spiral or helical flow path, a helical flow path, a tortuous flow path, or any combination thereof. The heating loop 460 is coupled to the manifold 464 of the heat exchanger 418 at an inlet 468 and an outlet 470. The shell or body 462 of the heat exchanger 412 may have a similar construction to the shell or body 430 of the heat exchanger 418. In certain embodiments, the housing or body 462 may include a U-shaped structure 472 having a module receptacle or chamber 480 surrounded by two opposing sides 474 and 476 (e.g., an upstream side and a downstream side) and a side 478 (e.g., a lateral side) adjacent to the manifold 464. The chamber 480 is configured to receive the adsorption module 100 when disposed in the desorption unit 420. Thus, the U-shaped structure 472 has a heating circuit 460 extending along the sides 474, 476, and 478, thereby providing heating along at least three sides of the chamber 480 and the adsorption module 100.

[0093] The adsorption module 100 is configured to move in alternating directions (eg, back and forth) between the chamber 440 in the housing or body 420 within the conduit 102 of the adsorption unit 414 and the chamber 480 in the housing or body 462 within the conduit 104 of the desorption unit 420. Figure 2The movement of the adsorption module 100 is described in detail, wherein the adsorption module 100 can be moved back and forth between the chamber 440 in the adsorption unit 414 and the chamber 480 in the desorption unit 420 via the linear positioning assembly 132 of the movable adsorption assembly 108. In certain embodiments, the controller 76 can be configured to selectively engage or disengage the heating system 166 and the cooling system 168 based on the position of the adsorption module 100, particularly for those assigned or coupled to the adsorption module 100. Figure 2 The heating system 166 and the cooling system 168 of each individually movable adsorption assembly 108 are shown. If the adsorption module 100 is disposed in the adsorption unit 414, the controller 76 may deactivate the heating system 168 and activate and / or control the cooling system 166 to provide a suitable temperature range for the adsorption process. If the adsorption module 100 is disposed in the desorption unit 420, the controller 76 may deactivate the cooling system 166 and activate and / or control the heating system 168 to provide a suitable temperature range for the desorption process.

[0094] The heating system 168 is configured to circulate a heating fluid 482 from the heating supply system 416 into the inlet 468 of the manifold 464, through the heating circuit 460, and out through the outlet 470 of the manifold 464 back to the heating supply system 416. In certain embodiments, the heating supply system 416 receives the heating fluid 482 already in a heated state within a suitable temperature range, so that any heater or heat exchanger in the heating supply system 416 does not perform additional temperature regulation. For example, the heating supply system 416 may receive the heating fluid 482 from another heated fluid source in the gas turbine system 10, such as heated water and / or steam 96 from the HRSG 27, the steam turbine 29, and / or the boiler 95. However, in certain embodiments, the heating supply system 416 receives the heating fluid 482 at a temperature outside the desired temperature range, and thus the heating supply system 416 may perform additional temperature control (e.g., heating and / or cooling) on ​​the heating fluid 482 to regulate the temperature within the suitable temperature range. For example, the heating fluid 482 may be heated by one or more additional heaters or heat exchangers of the heating supply system 416 , or the heating fluid 482 may be cooled by one or more additional coolers or heat exchangers of the heating supply system 416 .

[0095] Thus, the heating supply system 416 may include a single heat exchange or single fluid system 484 and / or a multiple heat exchange or multiple fluid system 486 configured to supply a heating fluid 482 at a suitable temperature range for circulation and heating through the heating loop 460. In other words, the heating fluid 482 may be the only heating fluid (e.g., liquid or gas) used by the single fluid system 484, while the heating fluid 482 (e.g., liquid or gas) may be heated by another heating fluid (e.g., liquid or gas) in the multiple fluid system 486. In certain embodiments, the heating supply system 416 may use heated water, steam, or another heated fluid to circulate directly through the heating loop 460 as the heating fluid 482, or indirectly circulate as another heating fluid in another heat exchanger to provide heating to the heating fluid 482, or a combination thereof. In some embodiments, the heating supply system 416 includes one or more pumps, valves, pressure regulators, sensors, filters (e.g., particulate filters, separators, etc.), processing units (e.g., chemical processing units, ultraviolet light processing units, etc.), or any combination thereof, which are configured to control various parameters and quality of the heating fluid 482 supplied to the heat exchanger 418.

[0096] The heat exchange system 422 can also be used to provide cooling in the adsorption unit 414 via the heat exchanger 424 and heating in the desorption unit 420 via the heat exchanger 426. In the illustrated embodiment, the heat exchange system 422 has heat exchangers 424 and 426 disposed along a closed-loop heat transfer loop 490, which can be disposed in a shell or body 492 of the heat exchange system 422. The shell or body 492 can include shell portions 494 and 496 disposed in the respective conduits 102 and 104 of the adsorption unit 414 and the desorption unit 420. The shell portions 494 and 496 can be integral parts of the shell or body 492 or separate sections. However, the portions 494 and 496 of the shell or body 492 generally support at least a portion or all of the closed-loop heat transfer loop 490, including the heat exchangers 424 and 426, the compressor 498, and the expansion valve 500. In some embodiments, the compressor 498 and / or the expansion valve 500 may be disposed in the pipeline 102 , in the pipeline 104 , or external to both pipelines 102 and 104 .

[0097] The closed-loop heat transfer circuit 490 is configured to circulate the working fluid 502 through the heat exchanger 424, the compressor 498, the heat exchanger 426, the expansion valve 500, and back to the heat exchanger 424. While flowing through the closed-loop heat transfer circuit 490, the working fluid 502 generally transfers heat, undergoes a phase change (e.g., liquid and vapor), and / or is heated or cooled. In the illustrated embodiment, the heat exchanger 424 can be an evaporator 504, and the heat exchanger 426 can be a condenser 506. In operation, the exhaust gas 94 flows through the conduits 102 of the adsorption unit 414 and transfers heat to the working fluid 502 circulating through the evaporator 504 of the heat exchanger 424, thereby evaporating the working fluid 502 to produce warm gas or vapor, as indicated by arrow 508. Therefore, the heat transfer from the exhaust gas 94 to the working fluid 502 helps to cool the exhaust gas 94 while the adsorption module 100 adsorbs undesirable gases from the exhaust gas 94. The warm gas 508 then flows through the compressor 498, which compresses the warm gas 508 to produce hot gas, as indicated by arrow 510. The hot gas 510 then flows through the condenser 506 of the heat exchanger 426, thereby transferring heat from the hot gas 510 to the adsorption module 100 when disposed within the chamber 480 (e.g., serving as a heat source for the desorption process). When the heat is transferred to the adsorption module 100, the heat helps to desorb the undesirable gas from the adsorbent material within the adsorption module 100, as discussed above. In addition, when the heat is transferred to the adsorption module 100, the hot gas 510 cools and condenses in the condenser 506 of the heat exchanger 426, thereby producing a warm liquid, as indicated by arrow 512. The warm liquid 512 then passes through the expansion valve 500, which causes the warm liquid 512 to expand to provide cooling and produce a cold liquid, as indicated by arrow 514. The cold liquid 514 flows through the evaporator 504 of the heat exchanger 424, thereby providing cooling to the exhaust gas 94 in the pipes 102 of the adsorption unit 414. As such, the cold liquid 514 helps cool the exhaust gas 94 to a suitable temperature to facilitate adsorption of the undesirable gas in the adsorption module 100, while also being heated to produce warm gas 508 to continue circulating in the closed-loop heat transfer circuit 490 of the heat exchange system 422.

[0098] The working fluid 502 circulating throughout the closed-loop heat transfer circuit 490 may include any suitable thermal fluid that can undergo a phase change between a liquid and a gas or vapor. For example, the working fluid 502 may include a refrigerant, water, or any other suitable thermal fluid. In the illustrated embodiment, the evaporator 504 of the heat exchanger 424 is coupled to and extends around the U-shaped structure 438 of the shell or body 430 along two opposite sides 442 and 444, so that when disposed in the adsorption unit 414, the evaporator 504 can provide cooling across the chamber 440 and the adsorption module 100. Similarly, the condenser 506 of the heat exchanger 426 extends across the opposite sides 474 and 476 of the U-shaped structure 472 of the shell or body 462, thereby providing heating across the chamber 480 and the adsorption module 100 when disposed in the desorption unit 420. However, any suitable arrangement of the heat exchangers 424 and 426 may be used with the movable adsorption assembly 108 of the adsorption system 106.

[0099] As further illustrated, the adsorption unit 94 outputs a treated gas 97 after adsorbing the undesirable gas (e.g., CO2) in the adsorption module 100 of the movable adsorption assembly 108. The cooling system 166 is configured to provide cooling to provide a suitable temperature for the exhaust gas 94 and / or the adsorbent material in the adsorption module 100, thereby improving the adsorption process in the adsorption module 100 within the adsorption unit 414. Therefore, the cooling system 166 is configured to provide cooling to the chamber 440 and the adsorption module 100 when disposed in the adsorption unit 414, thereby helping to adsorb the undesirable gas (e.g., CO2) from the exhaust gas 94 into the adsorbent material of the adsorption module 100. In certain embodiments, the cooling system 166 may include a heat exchanger 412 coupled to the cooling supply system 410, a heat exchanger 424 of the heat exchanger system 422, or a combination thereof.

[0100] Similarly, the heating system 168 is configured to provide heating to provide a suitable temperature for the adsorbent material in the adsorption module 100, thereby improving the desorption process in the adsorption module 100 within the desorption unit 420. Therefore, the heating system 168 is configured to provide heat to the chamber 480 and the adsorption module 100 when disposed in the desorption unit 420, thereby helping to desorb the undesirable gas (e.g., CO2) from the adsorbent material of the adsorption module 100 and output the captured gas 520 (e.g., CO2). In certain embodiments, the heating system 168 may include a heat exchanger 418 coupled to the heat supply system 416, a heat exchanger 426 of the heat exchanger system 422, or a combination thereof.

[0101] The captured gas 520 may then flow through a downstream device 522, which may include a plurality of downstream components 524. The downstream components 524 are configured to facilitate extraction of the captured gas 520 from the desorption unit 420 and / or further processing of the captured gas 520. For example, the downstream components 524 may include a vacuum system 526, a dehydration system 528, a compression system 530, and a storage or pipeline 532. When the adsorption module 100 is disposed in the chamber 480 for the desorption process, the vacuum system 526 (e.g., a vacuum pump driven by an electric motor) is configured to provide suction or vacuum to extract the captured gas 520 from the pipeline 104 of the desorption unit 420. The dehydration system 528 is configured to extract any moisture, such as water content, from the captured gas 520. The compression system 530 is configured to compress the captured gas 520 for further storage or transportation via a storage or pipeline 532.

[0102] The controller 76 of the control system 14 is coupled to the sensors 86, the cooling system 166, the heating system 168, and the heat exchange system 422 of the thermal control system 101. Specifically, the controller 76 may be coupled to various components of the cooling supply system 410, the heating supply system 416, and the heat exchange system 422, such as the compressor 498, the expansion valve 500, or other flow control and monitoring devices. The sensors 86 may be disposed upstream and downstream of the movable adsorption assembly 108 in both the conduit 102 of the adsorption unit 414 and the conduit 104 of the desorption unit 420. Thus, the sensors 86 may provide sensor feedback, such as sensor feedback of temperature, gas composition, pressure, flow rate, or any combination thereof, both upstream and downstream of the movable adsorption assembly 108, which may facilitate control of the temperature in the adsorption unit 414 and the desorption unit 420 via the thermal control system 101. For example, if the sensor 86 indicates that the temperature in the adsorption unit 414 or the desorption unit 420 is too high or too low, the controller 76 can be configured to control the temperature via the cooling supply system 410 of the cooling system 166, the heating supply system 416 of the heating system 168, and the compressor 498 and / or the expansion valve 500 of the heat exchange system 422.

[0103] In certain embodiments, the adsorption system 106 of the gas treatment system 16 may include all or part of the thermal control system 101 for temperature control in the adsorption unit 414 and the desorption unit 420. For example, the thermal control system 101 may include only the heat exchange system 422, only the cooling system 166 with the heat exchanger 412, only the heating system 168 with the heat exchanger 418, or all aspects of the thermal control system 101, including the cooling system 166, the heating system 168, and the heat exchange system 422. In addition, the cooling supply system 410 and the heating supply system 416 may have various embodiments, such as single-fluid systems 450 and 484 and / or multi-fluid systems 452 and 486, as discussed in more detail below.

[0104] Fig.16 yes Figures 1 to 15 A schematic diagram of an embodiment of the gas processing system 16 further shows Fig.15 Detail of the single fluid systems 450 and 484 of the cooling supply system 410 and the heating supply system 416 of the thermal control system 101 of the gas turbine system 10. In certain embodiments, the single fluid systems 450 and 484 are configured to obtain thermal fluids (e.g., cooled fluid 552 and heated fluid 572) from other source devices in the gas turbine system 10, where the thermal fluids may already be at a suitable temperature for cooling and heating in the thermal control system 101. For example, the thermal control system 101 may include heat exchangers 412 and 418 disposed inside the respective adsorption units 414 and desorption units 420, where the thermal fluids (e.g., cooled fluid 552 and heated fluid 572) may be directed to the heat exchangers 412 and 418 from their respective source devices. The source devices may include the HRSG 27, the steam turbine 29, the boiler 95, a water cooling tower, a water reservoir, or any combination thereof. In some embodiments, additional heat exchangers may be used to adjust the temperature of the thermal fluid; however, the thermal fluid may still be received from other source devices and directed through heat exchangers 412 and 418 .

[0105] In the illustrated embodiment, the single fluid system 450 of the cooling supply system 410 includes a cooling control system 550 configured to receive a cooled fluid 552, such as water 554. The cooling control system 550 is configured to supply the cooled fluid 552 as the cooling fluid 448 through the cooling circuit 428 of the heat exchanger 412 disposed in the conduit 102 of the adsorption unit 414. The cooling control system 550 may include a plurality of cooling control components 556, such as cooling control components 558, 560, and 562. The cooling control component 558 may include one or more flow control components, such as one or more valves, pumps, pressure regulators, or any combination thereof, which may be controlled by the controller 76, which may be controlled by the controller 76 to control the flow of the cooled fluid 552 as the cooling fluid 448 enters and passes through the cooling circuit 428. The cooling control component 560 may include one or more filters or fluid treatment components, such as a particulate filter, an ultraviolet light treatment system, a chemical treatment system, a separator, or any combination thereof. The cooling control component 562 may include one or more temperature control components, such as a temperature sensor, a temperature control device to adjust the flow rate (e.g., via the flow control component 558), a temperature control device to adjust the temperature (e.g., a cooler and / or a heater), or any combination thereof. For example, the temperature control component may include a cooler configured to cool the cooled fluid 552 by transferring heat from the cooled fluid 552 via one or more heat exchangers to be used as the cooling fluid 448. For example, the cooler may include a fan configured to direct airflow through the heat exchanger to transfer heat from the cooled fluid 552, or the cooler may include a pump configured to circulate different fluids through the heat exchanger to transfer heat from the cooled fluid 552. For another example, the cooler may include one or more expanders (e.g., turbo expanders) configured to reduce the temperature of the cooled fluid 552 via an expansion process. In certain embodiments, if the temperature of the cooled fluid 552 is below the lower temperature threshold, the temperature control component may include a heater configured to heat the cooled fluid 552 by transferring heat to the cooled fluid 552 via one or more heat exchangers for use as the cooling fluid 448. In some embodiments, the temperature control component may exclude any additional heat exchangers, fans, pumps, and / or expanders, such that the cooled fluid 552 may be received and supplied to the heat exchanger 412 without any further temperature adjustment.

[0106] The cooling control system 550 may receive cooling fluid 552 from one or more sources located throughout the system 10. For example, the cooling fluid 552 may be received from the HRSG 27, the steam turbine 29, a water cooling tower, a water reservoir, a water treatment system for the gas turbine system 10, or another independent thermal system of the gas turbine system 10, or any combination thereof. In some embodiments, the cooling fluid 552 may not be directed from another external source in the gas turbine system 10, but rather, the cooling control system 550 may operate as a closed loop by circulating the cooling fluid 448 through the cooling circuit 428 and the cooling control system 550. In either case, the cooling control system 550 operates as a single-fluid system 450, using one cooling fluid 448 to circulate throughout the cooling circuit 428. The cooling system 166 having the single-fluid system 450 is substantially the same as described above with reference to FIG. Fig.15 The same operations are discussed above, wherein the cooling fluid 448 is provided to help regulate the temperature of the exhaust gas 94 and / or the adsorption module 100 to within a suitable temperature range to improve the adsorption process within the adsorption module 100 .

[0107] The heating system 168 has a heating supply system 416 with a single fluid system 484, wherein the single fluid system 484 includes a heating control system 570 configured to receive a heated fluid 572, such as steam 574. The heating control system 570 is configured to supply the heated fluid 572 as the heating fluid 482 for circulation throughout the heating loop 460 of the heat exchanger 418 in the desorption unit 420. The heated fluid 572 may include steam 574, such as steam 96 from the HRSG 27, the steam turbine 29, the boiler 95, one or more additional steam sources or generators, or any combination thereof. In some embodiments, the heated fluid 572 alternatively or additionally includes heated water, heated lubricant, or another heated liquid or gas available in the gas turbine system 10.

[0108] The heating control system 570 may include one or more heating control components 576, such as heating control components 578, 580, and 582. The heating control component 578 may include one or more flow control components, such as one or more valves, pumps, pressure regulators, or any combination thereof, which may be controlled by the controller 76 to control the flow of the heated fluid 572 as the heated fluid 482 enters and passes through the heating circuit 460. The heating control component 580 may include one or more filters or fluid treatment components, such as a particulate filter, an ultraviolet light treatment system, a chemical treatment system, a separator, a water removal unit or drain, or any combination thereof. The heating control component 582 may include one or more temperature control components, such as a temperature sensor, a temperature control device for adjusting the flow rate (e.g., via the flow control component 580, a temperature control device for adjusting the temperature (e.g., a cooler and / or a heater), or any combination thereof. For example, the temperature control component may include a heater configured to heat the heated fluid 572 by transferring heat to the heated fluid 572 via one or more heat exchangers for use as the heating fluid 482. For example, the heater may include one or more electric heaters, or the heater may include a pump configured to circulate different fluids through the heat exchanger to transfer heat to the heated fluid 572. In certain embodiments, if the temperature of the heated fluid 572 is above an upper temperature threshold, the temperature control component may include a cooler configured to cool the heated fluid 572 by transferring heat from the heated fluid 572 via one or more heat exchangers for use as the heating fluid 482.

[0109] In some embodiments, the temperature control component may exclude any additional heat exchangers, heaters, coolers, and / or pumps so that the heated fluid 572 can be received and supplied to the heat exchanger 418 without further temperature adjustment. For example, depending on the conditions at one or more sources and the appropriate temperature range for the desorption process, the heating control system 570 may selectively extract or receive the heating fluid 572 from the one or more sources. In certain embodiments, the thermal control system 57 may selectively extract the heating fluid 572 (e.g., steam 574) from one or more of the low pressure (LP) section, the intermediate pressure (IP) section, and / or the high pressure (HP) section of the HRSG 27 and / or the steam turbine 29. Thus, depending on the extraction point from the HRSG 27 and / or the steam turbine 29, the steam 574 may be low pressure (LP) steam, intermediate pressure (IP) steam, or high pressure (HP) steam. The steam 574 may also be extracted from other sources, such as the boiler 95 and / or steam generator in the gas turbine system 10. Additionally, the heating fluid 572 may be a mixture of steam 574 and heated water. By controlling the extraction point, the heating control system 570 may be configured to supply the heated fluid 572 without further heating or, under some conditions, with some cooling to reduce the temperature.

[0110] Thus, the heating control system 570 regulates, processes, and controls the temperature of a heated fluid 572, such as steam 574, which can be used directly as the heating fluid 482 to heat the adsorbent material in the adsorption module 100 within the chamber 480 via heat exchange along the heating loop 460. Likewise, adding heat to the adsorption module 100 or transferring heat to the adsorption module facilitates desorption of the undesirable gas from the adsorption module 100, thereby producing the trapped gas 520. The heating fluid 482, such as steam 574, flows through the heating loop 460, thereby transferring heat to the adsorbent material in the adsorption module 100 and facilitating desorption of the undesirable gas to produce the trapped gas 520.

[0111] In the illustrated embodiment, the controller 76 of the control system 14 is coupled to both the cooling control system 550 and the heating control system 570 to monitor and control the temperature and supply of the cooling fluid 448 through the cooling circuit 428 and the heating fluid 482 through the heating circuit 460. Again, as described above with reference to Fig.15As discussed, the controller 76 may monitor the sensors 86 upstream and downstream of the adsorption module 100 (e.g., when disposed in the adsorption unit 414 and the desorption unit 420) to help control the adsorption and desorption processes by controlling the temperature in each of the adsorption unit 414 and the desorption unit 420. The controller 76 is also coupled to the heat exchange system 422 for controlling cooling by the heat exchanger 424 and heating by the heat exchanger 426, as described above with reference to Fig.15 In addition to the above, Fig.16 The adsorption system 106 of the gas treatment system 16 is similar to that described above with reference to Fig.15 What is being discussed is essentially the same.

[0112] Fig.17 yes Figures 1 to 15 1 is a schematic diagram of an embodiment of a gas processing system 16, further illustrating aspects of the multi-fluid systems 452 and 486 of the cooling supply system 410 and the heating supply system 416 of the thermal control system 101. In addition, the above reference Fig.15 The components and functionality described in Fig.17 In certain embodiments, the multi-fluid systems 452 and 486 are configured to obtain hot fluids (e.g., cooled fluid 552 and heated fluid 572) from other source devices in the gas turbine system 10, wherein the hot fluids may not be within a suitable temperature range to achieve or improve the adsorption of the undesirable gas in the adsorption unit 414 and / or the desorption of the undesirable gas in the desorption unit 420. Therefore, the multi-fluid systems 452 and 486 provide indirect heat transfer between the hot fluids (e.g., cooled fluid 552 and heated fluid 572) and the cooling fluid 448 and the heating fluid 482 via one or more additional heat exchangers (e.g., heat exchangers 602 and 622). Therefore, the multi-fluid system 452 is configured to provide heat exchange between at least two fluids to control the temperature within a suitable cooling temperature range to achieve or improve the adsorption process, while the multi-fluid system 486 is configured to provide heat exchange between at least two fluids to control the temperature within a suitable heating temperature range to achieve or improve the desorption process.

[0113] In the illustrated embodiment, the multi-fluid system 452 of the cooling supply system 410 includes a cooling control system 550 having a cooling control component 556, as discussed above. The cooling control system 550 is configured to receive a cooling fluid 552 (such as water 554), and condition the cooling fluid 552 and deliver it to a heat exchanger 602 as a cooling fluid 600. The heat exchanger 602 is configured to transfer heat (e.g., indirect heat transfer) between the cooling fluid 448 and the cooling fluid 600, wherein the cooling fluids 448 and 600 are separated from each other. The cooling fluid 448 circulates through the cooling circuit 428 of the heat exchanger 412 and the cooling circuit 604 of the heat exchanger 602, wherein the cooling circuits 428 and 604 together define a single closed-loop cooling circuit 606 extending through both the heat exchangers 412 and 602. In certain embodiments, the cooling circuit 604 of the heat exchanger 602 is removably or fixedly coupled to the cooling circuit 428 of the heat exchanger 412 , wherein the heat exchanger 602 is disposed outside the adsorption unit 414 and the heat exchanger 414 is disposed inside the adsorption unit 414 .

[0114] The heat exchanger 602 has a body or housing 608 having a cooling flow path 610 disposed along and around a cooling circuit 604. For example, the cooling flow path 610 may include one or more flow paths, channels, or cavities within the body or housing 608, wherein the cooling flow path 610 substantially surrounds the cooling circuit 604 within the body or housing 608. The cooling circuit 604 may include cooling coils, coiled tubing, or any combination thereof that are separate from the cooling flow path 610. In certain embodiments, the cooling circuit 604 may include one or more conduits or tubing extending in a coiled flow path, a winding flow path, a spiral or helical flow path, a helical flow path, a tortuous flow path, or any combination thereof.

[0115] In operation, the cooling fluid 600 from the cooling supply system 410 flows through the cooling flow path 610 of the heat exchanger 602, wherein the cooling fluid 600 is configured to adjust (e.g., reduce or increase) the temperature of the cooling fluid 448 circulating through the cooling circuit 606. For example, the cooling fluid 600 can transfer heat from the cooling fluid 448 in the heat exchanger 602, thereby cooling the cooling fluid 448 to a temperature within a suitable temperature range for the adsorption process. In some embodiments, the cooling fluid 600 can transfer heat to the cooling fluid 448 in the heat exchanger 602, thereby heating the cooling fluid 448 to a temperature within a suitable temperature range for the adsorption process. Therefore, the heat exchanger 602 generally transfers heat between the cooling fluid 448 and 600, so that the cooling fluid 448 is thermally adjusted to a temperature within a suitable temperature range for the adsorption process. The direction of heat transfer can depend on the source and temperature of the cooled fluid 552, the temperature of the exhaust gas 94, and other considerations.

[0116] After transferring heat between the cooling fluids 448 and 600, the heat exchanger 602 discharges the thermally conditioned cooling fluids 448 and 600. The cooling fluid 448 discharged from the heat exchanger 602 flows through the heat exchanger 412 to cool the exhaust gas 94, thereby achieving or improving the adsorption process. The cooling fluid 448 may then flow back to the heat exchanger 602 to complete the closed-loop cooling circuit 606, where the cooling fluid 448 then begins another pass through the closed-loop cooling circuit 606. In the illustrated embodiment, the closed-loop cooling circuit 606 includes one or more pumps 612 that are configured to pump the cooling fluid 448 through the closed-loop cooling circuit 606, including the cooling circuits 428 and 604 of the heat exchangers 412 and 602. Separately, after the cooling fluid 600 flows through and exits the heat exchanger 602, the cooling fluid 600 may flow or recirculate to the cooling control system 550 and / or flow along one or more flow paths to another location in the gas turbine system 10. In some embodiments, the cooling fluid 600 may flow through a closed-loop cooling circuit 614 having the cooling control system 550 and the heat exchanger 602 .

[0117] Thus, the multi-fluid system 452 includes at least the cooling fluid 448 circulating through the cooling circuit 606 (e.g., through the heat exchangers 412 and 602), and the cooling fluid 600 circulating through the cooling circuit 614 (e.g., through the heat exchanger 602 and the cooling control system 550). The cooling control system 550 is substantially the same as described above with reference to FIG. Fig.16However, the cooling control system 550 receives the cooled fluid 552 and outputs the cooling fluid 600 for cooling the cooling fluid 448 via indirect heat exchange in the heat exchanger 602. Other than that, the cooling supply system 410 including the multi-fluid system 452 is substantially the same as described above with reference to FIG. Fig.15 and Fig.16 The same operation is performed as discussed.

[0118] In the illustrated embodiment, the multi-fluid system 486 of the heating supply system 416 includes a heating control system 570 having a heating control component 576, as discussed above. The heating control system 570 is configured to receive a heated fluid 572, such as steam 574, and regulate the heated fluid 572 and deliver it to a heat exchanger 622 as a heating fluid 620. The heat exchanger 622 is configured to transfer heat (e.g., indirect heat transfer) between the heating fluid 482 and the heating fluid 620, wherein the heating fluids 482 and 620 are separated from each other. The heating fluid 482 circulates through the heating circuit 460 of the heat exchanger 418 and the heating circuit 624 of the heat exchanger 622, wherein the heating circuits 460 and 624 together define a single closed-loop heating circuit 626 extending through both the heat exchangers 418 and 622. In certain embodiments, the heating circuit 624 of the heat exchanger 622 is removably or fixedly connected to the heating circuit 460 of the heat exchanger 416, wherein the heat exchanger 622 is disposed outside the desorption unit 420 and the heat exchanger 418 is disposed inside the desorption unit 420.

[0119] The heat exchanger 622 has a body or housing 628 having a heating flow path 630 disposed along and around the heating circuit 624. For example, the heating flow path 630 may include one or more flow paths, channels, or cavities within the body or housing 628, wherein the heating flow path 630 substantially surrounds the heating circuit 624 within the body or housing 628. The heating circuit 624 may include one or more coils, coiled tubes, or any combination thereof that are separate from the heating flow path 630. In certain embodiments, the heating circuit 624 may include one or more conduits or tubes extending in a coiled flow path, a winding flow path, a spiral or helical flow path, a helical flow path, a tortuous flow path, or any combination thereof.

[0120] In operation, the heating fluid 620 from the heating supply system 416 flows through the heating flow path 630 of the heat exchanger 622, wherein the heating fluid 620 is configured to adjust (e.g., increase or decrease) the temperature of the heating fluid 482 circulating through the heating loop 626. For example, the heating fluid 620 can transfer heat to the heating fluid 482 in the heat exchanger 622, thereby heating the heating fluid 482 to a temperature within a suitable temperature range for the desorption process. In some embodiments, the heating fluid 620 can transfer heat from the heating fluid 482 in the heat exchanger 622, thereby cooling the heating fluid 482 to a temperature within a suitable temperature range for the desorption process. Therefore, the heat exchanger 622 generally transfers heat between the heating fluid 482 and 620, so that the heating fluid 482 is thermally adjusted to a temperature within a suitable temperature range for the desorption process. The direction of heat transfer can depend on the source and temperature of the heated fluid 572, the temperature of the adsorbent material in the adsorption module 200, and other considerations.

[0121] After transferring heat between the heating fluids 482 and 620, the heat exchanger 622 discharges the thermally conditioned heating fluids 482 and 620. The heating fluid 482 discharged from the heat exchanger 622 flows through the heat exchanger 418 to heat the adsorbent material in the adsorption module 100, thereby achieving or improving the desorption process. The heating fluid 482 may then flow back to the heat exchanger 622 to complete the closed-loop heating circuit 626, where the heating fluid 482 then begins another pass through the closed-loop heating circuit 626. In the illustrated embodiment, the closed-loop heating circuit 626 includes one or more pumps 632 that are configured to pump the heating fluid 482 through the closed-loop heating circuit 626, including the heating circuits 460 and 624 of the heat exchangers 418 and 622. Separately, after the heating fluid 620 flows through and exits the heat exchanger 622, the heating fluid 620 may flow or recirculate to the heating control system 570 and / or flow along one or more flow paths to another location in the gas turbine system 10. In some embodiments, the heating fluid 620 may flow through a closed-loop heating circuit 634 having a heating control system 570 and a heat exchanger 622 .

For another example, the duct 104 of the desorption unit 420 may extend along (e.g., parallel to) the exhaust stack 712, such that the desorption unit 420 is adjacent to the desorption unit 414 so that the adsorption module 100 can move back and forth between the exhaust stack 712 (e.g., duct 102) and the duct 104, as discussed in detail above. Specifically, each movable adsorption assembly 108 has one of the adsorption modules 100, which is configured to move between the ducts 102 and 104 in alternating directions, wherein the adsorption module 100 adsorbs undesirable gases in the duct 102 and desorbs undesirable gases in the duct 104. The adsorption unit 414 outputs the treated gas 97 downstream of the plurality of movable adsorption assemblies 108, while the desorption unit 420 outputs the captured gas 520 downstream of the plurality of movable adsorption assemblies 108. In the illustrated embodiment, the ducts 102 and 104 are generally oriented in a vertical direction associated with the exhaust stack 712, while the alternating direction of movement of the adsorption modules 100 is generally in a horizontal direction.

In certain embodiments, the compression system 530 may be a single-stage compressor, or the compression component 180 may include 3, 4, 5, or more compressors and associated intercoolers. The compression system 530 then outputs the compressed captured gas 746 to a storage or pipeline system 532. Thus, the compressed captured gas 746 may be used in a variety of applications, whether locally in the combined cycle power plant 700 or remotely via storage or pipeline system 532 .

[0137] The water supply system 734 may receive fresh water, condensed water, or other process water from various sources located throughout the combined cycle power plant 700. For example, the water supply system 734 may receive water from the dehydration system 528 as indicated by arrow 748 (e.g., a water conduit), water from the compression system 530 as indicated by arrow 750 (e.g., a water conduit), and water from the gas processing system 16 (e.g., a water conduit from the cooling system 166 and / or the heating system 168). The water supply system 734 may also supply water to various devices located throughout the combined cycle power plant 700. For example, the water supply system 734 may supply water to the HRSG 27 as indicated by arrow 752 (e.g., via a water conduit) for steam generation of the steam 96, and to the gas processing system 16 for various cooling processes within the adsorption system 106. For example, the water supply system 734 may supply the cooled fluid 552 (eg, water 554 ) to the cooling system 166 (eg, the cooling supply system 410 ) as indicated by arrow 754 (eg, via a water conduit).

[0138] Given the various sources and uses of water, the water supply system 734 may include a plurality of water components 756, such as a water storage device 758, a thermal control system 760, and a water treatment system 762.

For example, the thermal control system 760 may include a cooling tower, an indirect heat exchanger that uses another thermal fluid to provide cooling, one or more fans, a refrigeration system, a heating system that uses heat from various sources in the combined cycle power plant 700, or any combination thereof. The water treatment system 762 may include one or more of a filtration system, a chemical treatment system, an impurity removal system, an ultraviolet light treatment system, or any combination thereof. Thus, the water supply system 734 can supply thermally controlled and treated water to various locations throughout the combined cycle power plant 700, including but not limited to the HRSG 27 and the gas processing system 16 (e.g., the cooling supply system 410 of the adsorption system 106). In the illustrated embodiment, the water treatment system 762 is shared between various components, equipment, or subsystems of the combined cycle power plant 700.

[0139] In operation, the controller 76 is configured to control the thermal control system 101 and the adsorption system 106 of the gas processing system 16 to achieve or improve the efficiency of the adsorption process in the adsorption unit 414 and the desorption process in the desorption unit 420. The temperature in the adsorption unit 414 affects the adsorption process, and thus the controller 76 facilitates controlling the temperature in the adsorption unit 414 based at least in part on the extraction of the cooled fluid 552 from the combined cycle power plant 700. For example, the controller 76 may selectively control the extraction point (e.g., a specific device such as the HRSG 27, the steam turbine 29, the dehydration system 528, and / or the compression system 530), the mixing of multiple extractions, additional heat exchange (e.g., conditioning by heating or cooling), or other parameters of the cooled fluid 552 so that the cooling supply system 410 of the cooling system 166 receives the cooled fluid 552 at a temperature within a suitable temperature range for the adsorption process.

[0140] Similarly, the temperature in the desorption unit 420 affects the desorption process, and thus the controller 76 helps control the temperature in the desorption unit 420 based at least in part on the extraction of the heated fluid 572 from the combined cycle power plant 700. For example, the controller 76 may selectively control the extraction point (e.g., specific equipment such as the HRSG 27, steam turbine 29, and boiler 95), the mixing of multiple extractions, additional heat exchange (e.g., conditioning by heating or cooling), or other parameters of the heated fluid 572 so that the heating supply system 416 of the heating system 168 receives the heated fluid 572 at a temperature within a suitable temperature range for the desorption process. As another example, the controller 76 can selectively control the extraction points of the heated fluid 572 from different sections 704 of the HRSG 27 (e.g., the LP section 706, the IP section 708, and / or the HP section 710) and / or different sections of the steam turbine 29 (e.g., the LP turbine, the IP turbine, and / or the HP turbine) to provide LP steam, IP steam, and / or HP steam as the heated fluid 572 for the heating system 168. In general, the controller 76 facilitates controlling the temperatures in the adsorption unit 414 and the desorption unit 420, the movement of the adsorption module 100 between the adsorption unit 414 and the desorption unit 420, the downstream equipment 522 for controlling post-processing of the captured gas 520, and various equipment of the combined cycle power plant 700 that facilitates supporting the adsorption system 106 of the gas processing system 16.
