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, undesirable gases may include hydrogen sulfide (H2S). 2 S), carbon oxides such as carbon dioxide (CO 2 ), nitrogen oxides such as nitrogen dioxide (NO 2 ), and / or sulfur oxides such as sulfur dioxide (SO 2 ). Therefore, it may be desirable to treat certain gases to remove undesirable gases from the gas stream, such as by removing undesirable gases from the fuel gas upstream of the combustion system and / or removing undesirable gases from the exhaust gas emitted by the combustion system. The 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, the solvent-based absorption system typically includes a variety of equipment external to the pipeline carrying the gas stream (e.g., a fuel supply pipeline or an exhaust pipeline), and thus can increase the cost, complexity, and footprint of the solvent-based absorption system. Therefore, there is a need for a gas treatment system that can operate continuously without relying on a solvent-based absorption system. Summary of the invention

[0022] One or more specific embodiments of the currently disclosed system are described below. In order to provide a concise description of these embodiments, all features of the actual implementation may not 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 for the ordinary technician who benefits from the present disclosure to design, make and manufacture.

[0023] 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.

[0024] The disclosed embodiments include gas treatment systems and methods capable of using multiple adsorption modules for gas treatment, which are configured to move back and forth between a first pipeline for adsorption of undesirable gases and a second pipeline for desorption of undesirable gases. 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 gases in the first pipeline, while one or more adsorption modules desorb undesirable gases in the second pipeline. Various aspects and embodiments of the gas treatment system are discussed in further detail below.

[0025] Figure 11 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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 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. 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 turbine 29 can be configured to drive a generator or other loads.

[0031] 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.

[0032] 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 (CO 2 ) and carbon monoxide (CO), nitrogen oxides (NO X ), sulfur oxides (SO X ) such as sulfur dioxide (SO 2 ) or any combination thereof. The disclosed embodiments are particularly suitable for CO removal from exhaust gas. 2However, the following discussion is intended to cover each of these examples when undesirable gases are involved.

[0033] 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.

[0034] In operation, incoming gas (e.g., exhaust gas 94 from the turbine section 24, 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 gas, 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 gas 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 .

[0035] The gas treatment system 16 may include downstream equipment 99 located downstream of the adsorption module 100, such as a vacuum system, a fluid separation system, or any combination thereof. The vacuum system may include the above-mentioned equipment. The fluid separation system may include a flash tank, an absorber, or other equipment to separate the fluid 15 from the desorbed gas (e.g., the undesirable gas). The gas treatment system 16 may use the downstream equipment 99 to separate and capture the undesirable gas (e.g., CO) from the fluid 15 (e.g., steam). 2 ) so that the captured gas can be used for other applications. Therefore, the gas processing system 16 can be described as a carbon capture adsorption system.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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).

[0040] 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 (CO 2 ) and carbon monoxide (CO), nitrogen oxides (NO X ), sulfur oxides (SO X ) such as sulfur dioxide (SO 2 ), hydrogen sulfide (H 2S) or any combination thereof. The pipeline 104 is configured to receive and transfer a fluid stream 130, which may include steam, an inert gas such as nitrogen, air, 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.

[0041] 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.

[0042] 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.

[0043] 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 .

[0044] 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.

[0045] 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 adsorption of the undesirable gas, such 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 CO. 2 , H 2 S. SO 2 、NO 2 Or any combination thereof. In the pipeline 104, the fluid stream 130 provides heat to facilitate desorption of undesirable gases from the adsorption modules 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 modules 100 and desorb undesirable gases from the adsorption modules 100 for subsequent capture, cooling, and compression. Therefore, the pipeline 104 discharges a cooled fluid stream 156, such as cooled steam. In certain embodiments, undesirable gases are desorbed from the adsorption modules 100 into the pipeline 104, which then transports the desorbed gases together with the cooled fluid stream 156 for subsequent capture, cooling, and compression. Alternatively or additionally, the desorbed gases can be separated and captured at each individual adsorption module 100.

[0046] The gas treatment system 16 may also include one or more temperature control systems, such as a cooler 158 and a heater 160. For example, the fluid stream 128 entering the pipeline 102 may be a heated fluid stream, such as exhaust gas, and thus 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 and / or around the adsorption module 100. 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. 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 sufficiently high to help induce desorption of the undesirable gas from the adsorption module 100. In certain embodiments, the conduit 104 may exclude the heater 160 and / or the controller 76 may not operate the heater 160 if the fluid stream 130 is sufficiently hot or above a threshold temperature.

[0047] 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.

[0048] As further illustrated, the control system 14 has a controller 76 coupled to each of the actuators 146 of the linear positioning assembly 132 disposed throughout each of the pipes 102 and 104, the one or more coolers 158, the one or more heaters 160, and the plurality of sensors 86. 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.

[0049] 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.

[0050] 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 and the heater 160. For example, the controller 76 may be configured to control the temperature in the pipe 102 to remain at or below a threshold temperature, while the controller 76 may be configured to control the heater 160 to maintain the temperature in the pipe 104 at or above a threshold temperature. Figures 3 to 14 Further details of the sorption module 100, the movable sorption assembly 108, the cooler 158, and the heater 160 are discussed in greater detail.

[0051] Figure 3 is a schematic diagram of an embodiment of a temperature control system 170 configured to provide Figure 2 The temperature control system 170 may include a heat exchanger 172, a heat exchanger 174, and a fluid circuit 176 extending between and through the heat exchangers 172 and 174. 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.

[0052] 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.

[0053] 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.

[0054] 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 processing system 16. Thus, the direct heat exchange system 190 may be configured as a cooler 158 by injecting a relatively low temperature fluid into the fluid stream 128, or the direct heat exchange system 190 may be configured as a heater 160 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, or another suitable gas or liquid.

[0055] Figure 5 yes Figure 1 and Figure 2 100 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.

[0056] 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 .

[0057] 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 .

[0058] 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 6 The 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).

[0059] 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.

[0060] 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 6 Any 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.

[0061] 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.

[0062] 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 7 The 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Fig.10 is along Fig. 9A 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] Fig.14 It is used to process Figure 1 Flow chart of an embodiment of a process 380 for treating gases in a system of a gas treatment system 10. 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 gases may include CO 2 , H 2 S. SO 2 、NO 2or 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 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 parameters with one or more thresholds, as shown in box 386. For example, the process 380 may include comparing the adsorption rate with 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.

[0074] 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).

[0075] 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.

[0076] 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.

[0077] The technical effects of the embodiments disclosed in the present invention include a gas treatment system having adsorption modules that move linearly between flow paths in a first pipe and a second pipe, wherein the adsorption modules adsorb undesirable gases in the first pipe and desorb undesirable gases in the second pipe.
