[0001] This application claims priority to international application PCT / US2023 / 030313, filed on August 16, 2023, the entire contents of which are incorporated herein by reference. Background Technology

[0002] This disclosure relates generally to trapping systems and methods, and more specifically to systems and methods for facilitating the adsorption and desorption of water vapor and carbon dioxide gases by controlling the temperature of the gas flow directed through the adsorption bed to optimize the adsorption module of the adsorption bed.

[0003] At least some known industrial and power generation methods may result in gas streams containing pollutants such as carbon dioxide (CO2). To facilitate the removal of pollutants from gas streams before they are released into the atmosphere, at least some known systems include capture systems. For example, capture systems can be used to capture CO2 and store it underground to help reduce the amount of CO2 that is not intended to be released into the atmosphere.

[0004] At least some known capture systems use adsorption beds to capture CO2. In some of these systems, adsorbent material may be used in conjunction with the adsorption bed to enhance the adsorption and desorption of CO2. To further increase the amount of CO2 captured, at least some known capture systems use direct heating and cooling of the adsorption bed, typically utilizing gas or a stream. However, direct heating and cooling can contaminate the adsorbent material.

[0005] In some known systems, in contrast to conventional liquid amine-based CO2 capture processes, solid adsorbent materials can be used in conjunction with adsorption beds to enhance CO2 adsorption and desorption, thereby increasing adsorption capacity and system efficiency. However, the effectiveness of solid adsorbent systems may be limited by the chemical structure and / or thickness of the solid adsorbent material. Furthermore, water present in the gas stream, such as water vapor (H2O), may reduce the adsorption and desorption effectiveness of the solid adsorbent material, and the temperatures at which water is efficiently adsorbed and desorbed may not match those at which carbon dioxide is efficiently adsorbed and desorbed.

[0006] Therefore, there is a need for a capture system and method that uses temperature management to guide the gas flow through the adsorption bed to optimize the efficiency and productivity of adsorption and desorption of carbon dioxide and water through one or more solid adsorbents within the adsorption module of the adsorption bed. Summary of the Invention

[0007] In one aspect, a method for capturing carbon dioxide is provided. The method includes: receiving a gas stream through an adsorption bed comprising one or more adsorption modules and one or more temperature regulating modules; and receiving at least one regulating stream through one or more contactors for controlling the temperature of at least one of the one or more adsorption modules and the gas stream. The method further includes: adsorbing at least one of water vapor and carbon dioxide from the gas stream through the one or more adsorption modules; and discharging an exhaust stream through the adsorption bed that has exhausted at least one of the water vapor and carbon dioxide. The method further includes: regulating the temperature of the gas stream exiting the one or more temperature regulating modules to promote an increase in the amount of at least one of the water vapor and carbon dioxide captured by the adsorption bed and subsequently released.

[0008] In another aspect, a capture system for capturing carbon dioxide is provided. The capture system includes an adsorption bed comprising one or more adsorption modules and one or more temperature control modules. The adsorption bed is oriented to receive a gas stream, adsorb at least one of water vapor and carbon dioxide from the gas stream within the one or more adsorption modules, and discharge an exhaust stream depleted of at least one of the water vapor and carbon dioxide. The capture system also includes one or more contactors oriented to receive at least one control stream for controlling the temperature of the one or more adsorption modules and the at least one of the gas streams. The capture system also includes a controller configured to regulate the temperature of the gas stream exiting the one or more temperature control modules to facilitate an increase in the amount of at least one of the water vapor and carbon dioxide captured by the adsorption bed and subsequently released.

[0017] Figure 1This is a schematic diagram of an exemplary capture system 100 that can be used to capture CO2 using an adsorption bed 102. In an exemplary embodiment, the adsorption bed 102 includes at least one adsorption module 104. More specifically, in an exemplary embodiment, the adsorption bed 102 includes four adsorption modules 104a to 104d. In some embodiments, the capture system 100 may include more or fewer than four adsorption modules 104. Furthermore, in an exemplary embodiment, the adsorption bed 102 includes an inlet 106 and an outlet 108. The inlet 106 and the outlet 108 are oriented such that, during operation, a gas flow 110 received through the inlet 106 is directed to flow through each adsorption module 104 in series toward the outlet 108. As the gas flow 110 is directed through each adsorption module 104, the adsorption bed 102 captures CO2 and / or H2O from the gas flow 110 and discharges a CO2-depleted exhaust flow 112 through the outlet 108.

[0018] Typically, gas stream 110 can be any suitable gas known in the art that includes contaminants intended for removal. For example, gas stream 110 can be air, flue gas, afterburner gas, natural gas, and / or combinations thereof. In an exemplary embodiment, gas stream 110 includes CO2. In some embodiments, CO2 may be present in gas stream 110 in the range of about 400 ppm to about 15 v%. In other embodiments, CO2 may be present in gas stream 110 in the range of about 0.04 v% to about 30 v%.

[0019] In an exemplary embodiment, the CO2 concentration of gas stream 110 is typically highest when it enters inlet 106. As CO2 is adsorbed by each subsequent adsorption module 104, the CO2 concentration in gas stream 110 decreases as it is guided through adsorption modules 104a to 104d toward outlet 108. In an exemplary embodiment, the CO2 concentration in gas stream 110 flowing through adsorption modules 104a to 104d is lowest at outlet 108.

[0020] Additionally, in an exemplary embodiment, the gas stream 110 includes H2O. For example, the gas stream 110 may be received by the first adsorption module 104a of the adsorption bed 102 at a specific humidity level. In an exemplary embodiment, the H2O concentration is typically highest when the gas stream 110 enters the inlet 106.

[0021] The adsorption bed 102 may also include one or more temperature control modules 160. When the gas flow 110 is guided from the inlet 106 through one or more adsorption modules 104 through the adsorption bed 102 to the outlet 108, the gas flow 110 may also be guided through one or more temperature control modules 160. The temperature control modules 160 may be located in the adsorption bed 102, adjacent to one or more adsorption modules 104. For example, the temperature control module 160 may be located between two adsorption modules 104, such as, but not limited to, between a first adsorption module 104a and a second adsorption module 104b. Figure 1 As shown. Figure 1 The positioning of one or more temperature control modules 160 and one or more adsorption modules 104 shown is intended to be illustrative and not restrictive, as the gas flow 110 can be... Figure 1 The different sequences shown are guided through one or more temperature control modules 160 and one or more adsorption modules 104.

[0022] In an exemplary embodiment, the adsorption module 104 includes a contactor 114. The contactor 114 includes a contactor inlet 118, a contactor outlet 120, and a fluid circuit 202. Figure 2 As shown in the diagram, the fluid circuit is defined between the contactor inlet 118 and the contactor outlet 120 and extends from the contactor inlet to the contactor outlet. In an exemplary embodiment, the adsorption module 104 also includes a plate 204 ( Figure 2 As shown in the diagram, the plate is coated with a solid form of adsorbent 116 to facilitate the adsorption of CO2 and / or H2O. For example, the adsorbent 116 may be, but is not limited to, a powder, a composite mixed with a binder, a membrane or coating, a packed bed, and / or a column. In some embodiments, if all adsorption modules 104a to 104d are configured to capture CO2, the adsorbent 116 within each adsorption module 104 may be the same. In other embodiments, if at least one of the adsorption modules 104a to 104d is configured to capture H2O, the adsorbent 116 within at least one adsorption module 104 may be different. In an exemplary embodiment, the contactor 114 and the plate 204 are adjacent to each other to facilitate indirect heating and / or cooling of the adsorbent 116 coated on the plate 204.

[0023] In an exemplary embodiment, the flow 122 received through contactor inlet 118 is transmitted via fluid circuit 202 ( Figure 2 The heat transfer between the flow 122 (shown in the diagram) and the plate 204 facilitates the regulation of the temperature of the adsorbent 116 coated on the plate 204. For example, the regulation temperature T of the flow 122... reg It can be used to increase or decrease the control temperature T of the adsorption module 104. cntlIn some embodiments, flow 122 may be in liquid form. In other embodiments, flow 122 may be in gaseous form. The convection between flow 122 flowing through fluid loop 202 and adsorbent 116 coated on plate 204 helps control the temperature of adsorbent 116 without the risk of contamination that could occur due to direct contact with flow 122.

Figure 2 The design of one or more adsorption modules 104 shown differs. Additionally, the term "contaminator" is used throughout the text to refer to heat exchange elements and should be interpreted accordingly.

[0024] Flow 122 may consist of a mixture of cold flow 132 and hot flow 134, and may exit the contactor outlet 120 as a mixed flow 123. The mixture of cold flow 132 and hot flow 134 may help regulate the temperature of the adsorbent 116. For example, the cold temperature T of cold flow 132... cld The heat temperature T of 134 heat flow hot The mixture can be used to increase or decrease the regulating temperature T of flow 122. reg In order to control the control temperature T of the adsorption module 104 cntl In some embodiments, cold flow 132 and hot flow 134 may each comprise water (H2O) in liquid (e.g., water) or gaseous (e.g., steam) form. For example, H2O may be present in cold flow 132 and / or hot flow 134 in the range of about 50 v% to 100 v%. In other embodiments, cold flow 132 and / or hot flow 134 may comprise non-aqueous fluids.

[0025] In an exemplary embodiment, the temperature control module 160 includes a secondary contactor 162. The secondary contactor 162 includes a secondary contactor inlet 164, a secondary contactor outlet 166, and a secondary fluid circuit 168. Figure 3 As shown in the diagram, the secondary fluid circuit is defined between the secondary contactor inlet 164 and the secondary contactor outlet 166, and extends from the secondary contactor inlet to the secondary contactor outlet. The secondary flow 170 received through the secondary contactor inlet 164 facilitates flow via the secondary fluid circuit 168 (… Figure 3 The temperature of the gas flow 110 guided through the temperature regulation module 160 is regulated by heat transfer between the secondary flow 170 flowing inside the module and the gas flow 110 within the temperature regulation module 160.

In other embodiments, the secondary flow 170 may be in gaseous form. The convection between the secondary flow 170 flowing through the secondary fluid circuit 168 and the gas flow 110 within the temperature control module 160 facilitates control of the gas temperature T of the gas flow 110. gas There is no risk of contamination from direct contact with secondary flow 170. For example... Figure 3 The design of the secondary contactor 162 shown is intended to be illustrative and not restrictive, as the design of the secondary contactor 162 can be used with... Figure 3 The design of one or more temperature control modules 160 shown differs. Additionally, the term "contaminant" is used throughout the text to refer to heat exchange elements and should be interpreted accordingly.

[0027] In an exemplary embodiment, the trapping system 100 also includes a controller 124 for dynamically regulating the operation of the trapping system 100. For example, the controller 124 can adjust the regulating temperature T of the flow 122. reg To control the control temperature T of at least one adsorption module 104 cntl And / or by changing the secondary regulating temperature T of the secondary flow 170 reg2 To control the gas temperature T of gas flow 110 gas To facilitate optimized capture of CO2 and / or H2O, as further described herein.

[0028] Controller 124 monitors the temperature of flow 122 and / or plate 204 ( Figure 2 The temperature of the adsorbent 116 in the (shown) is used to facilitate the regulation of the temperature of each adsorption module 104a to 104d. For example, the controller 124 can use the contactor sensor 126 (shown in the diagram) Figure 4 (As shown) The regulating temperature T of the monitoring flow 122 reg Additionally, for example, controller 124 can use module sensor 128 ( Figure 4 (As shown) The control temperature T of at least one adsorption module 104 is monitored. cntl .

In an exemplary embodiment, the regulated temperature T of the flow 122 is monitored within each adsorption module 104a to 104d. reg In some implementations, the regulating temperature T of flow 122 reg The conditions can be substantially consistent in each adsorption module 104.

Figure 4 (As shown in the diagram). Therefore, the controller 124 can generate a temperature distribution that includes the regulated temperature T of the flow 122 within any or all of the adsorption modules 104a to 104d. reg The change value.

[0031] Adjustment temperature T of flow 122 reg The temperature of the extracted steam stream (not shown) from a steam turbine (not shown) can be used as a basis. For example, the steam turbine may be part of a combined cycle power plant (not shown), where the extracted steam stream from the steam turbine is used to change the temperature of stream 122. In some embodiments, the extracted steam stream can heat stream 122 by convective transfer via one or more heat exchangers (not shown), either directly replacing the mixing of cold stream 132 and hot stream 134 or indirectly heating hot stream 134.

[0032] Controller 124 monitors the secondary regulation temperature T of secondary flow 170. reg2 To promote the regulation of gas flow 110 and increase gas temperature T gas For example, controller 124 can use secondary contactor sensor 172 ( Figure 4 (As shown) Monitor the secondary regulation temperature T of secondary flow 170 reg2 Alternatively, for example, controller 124 may use gas flow sensor 174 located near the outlet of one or more temperature regulation modules in temperature regulation module 160.

In other embodiments, the gas temperature T of the gas flow 110 is... gas The specific temperature control can vary in different temperature control modules 160.

[0035] One or more adsorption modules in adsorption module 104 (such as, but not limited to, first adsorption module 104a) can be used to adsorb and desorb H2O contained in gas stream 110. Optimizing the operating conditions of adsorption module 104 for the adsorption and desorption of H2O facilitates the optimization of the operating conditions of subsequent adsorption modules (such as, but not limited to, second adsorption module 104b, third adsorption module 104c, and fourth adsorption module 104d) for the adsorption and desorption of CO2. The solid adsorbent material (adsorbent 116) of one or more adsorption modules configured for the adsorption and desorption of H2O may be substantially the same or different from that of one or more adsorption modules configured for the adsorption and desorption of CO2. The adsorbent 116 in first adsorption module 104a may be any suitable adsorbent known in the art that promotes the capture of H2O as described herein. In addition, the thickness of adsorbent 116 in first adsorption module 104a may be any suitable thickness known in the art that promotes the capture of H2O.

[0036] In some embodiments, desorption within adsorption bed 102 can occur simultaneously for CO2 and H2O. Therefore, in these embodiments, the desorbed CO2 and H2O will need to be separated downstream. In other embodiments, desorption within adsorption bed 102 can occur sequentially for CO2 and H2O. For example, adsorption module 104 can be controlled, for instance, by sequentially heating the adsorbent 116 within adsorption module 104, which is specific for the desorption of CO2 and / or H2O, to first desorb one of CO2 or H2O, and then the other of CO2 or H2O.

[0037] Typically, due to the heat generated during the exothermic process of adsorbing H2O and CO2 as the gas stream 110 is guided from the inlet 106 to the outlet 108 of the adsorption bed 102, the gas temperature T of the gas stream 110 entering the fourth adsorption module 104d is... gas The temperature of the gas flow 110 entering any of the first adsorption modules 104a to the third adsorption module 104c is higher than the temperature of the gas flow 110. Therefore, when the gas flow 110 is guided from the first adsorption module 104a to the fourth adsorption module 104d, the gas temperature T of the gas flow 110 is higher than the temperature of the gas flow 110 entering any of the first adsorption modules 104a to the fourth adsorption module 104d. gas The temperature typically rises. As the gas stream 110 is guided through the adsorption bed 102, the secondary flow 170's secondary regulation temperature T is increased based on the heat generated within the adsorption module 104. reg2 The temperature control module 160 may vary.

[0038] Additionally, when the gas stream 110 is guided through the adsorption bed 102, the temperature T of the stream 122 is adjusted based on the heat generated within the adsorption module 104. reg The temperature T of the adsorption module 104 can vary in one or more adsorption modules 104. For example, for the fourth adsorption module 104d, the temperature T of the flow 122 is adjusted. reg The lowest possible temperature can be used to maximize the CO2 captured from the gas stream 110 in the adsorption modules 104a to 104d at its lowest CO2 content. Additionally, for example, after H2O in the gas stream 110 has been adsorbed (which may have its own optimal control temperature), during the adsorption operation mode in which the gas stream 110 is at its highest CO2 content in the adsorption modules 104a to 104d, the regulating temperature T of the stream 122 is [not specified in the original text]. reg It can be the highest temperature to manage CO2 capture.

[0039] By changing the adjustment temperature T of the flow 122 in different adsorption modules 104a to 104d regThe controller 124 can facilitate the optimization of the adsorption of CO2 and / or H2O by the adsorption bed 102, thereby improving the adsorption and desorption capacity of the adsorption bed 102. Typically, increasing the percentage of module capacity used by at least one adsorption module 104a to 104d increases the efficiency of the trapping system 100. For example, changing the regulating temperature T of the flow 122 in the adsorption modules 104a to 104d... reg To reduce the control temperature T of the subsequent adsorption modules 104a to 104d cntl This can increase the percentage of module capacity used by subsequent adsorption modules (such as adsorption modules 104b to 104d), thereby improving the efficiency of the capture system 100.

For example, the temperature for efficient adsorption and desorption of H2O may differ from the temperature for efficient adsorption and desorption of CO2. Therefore, the control temperature T, independent of the adsorption module 104, is... cntl The temperature T of the gas flow 110 is controlled. gas It can promote and improve the adsorption and desorption capacity of adsorption bed 102.

[0041] Typically, increasing the percentage of adsorption module capacity used by at least one adsorption module 104a to 104d improves the efficiency of the trapping system 100. For example, changing the secondary regulation temperature T of the secondary flow 170 in one or more temperature regulation modules 160... reg2 This can increase the percentage of adsorption module capacity used by subsequent adsorption modules (e.g., one or more downstream adsorption modules 104 of temperature control modules 160), thereby improving the efficiency of the trapping system 100.

[0042] like Figure 1 As shown, one example is controlling the secondary regulating temperature T of the secondary flow 170 exiting the temperature regulating module 160 located between the first adsorption module 104a and the second adsorption module 104b. reg2 This increases the percentage of module capacity used by subsequent adsorption modules, adsorption modules 104b to 104d, thereby improving the efficiency of the trapping system 100. However, this example is intended to be illustrative and not limiting, as any number of temperature control modules 160 may be included in the adsorption bed 102 to be positioned before, after, or between any adsorption module 104 in the adsorption bed 102.

[0043] One or more adsorption beds 102 can be used to capture CO2 and / or H2O. That is, although Figure 1 Only one adsorption bed 102 is shown, but this is intended to be illustrative and not restrictive, as the capture system 100 may include more than one adsorption bed 102. For example, multiple adsorption beds 102 may be included in the capture system 100, wherein the inlet 106 of each adsorption bed 102 is connected in parallel to receive the gas stream 110, and the outlet 108 of each adsorption bed 102 is also connected in parallel to discharge the exhaust stream 112.

In an exemplary embodiment, the contactor 114 includes a fluid loop 202 extending between a contactor inlet 118 and a contactor outlet 120. The plate 204 is coated with an adsorbent 116 to adsorb CO2 and / or H2O.

Figure 1 (As shown in the diagram) CO2 and / or H2O are captured. In an exemplary embodiment, controller 124 includes memory 402 and processor 404.
