[0004] At least some known capture systems capture CO2 using an adsorption bed. In some such capture systems, an adsorbent material may be used along with the adsorption bed to facilitate the adsorption and desorption of CO2. To facilitate increasing the amount of CO2 captured, at least some known capture systems use direct heating and cooling of the adsorption bed. However, direct heating and cooling can contaminate the adsorbent material. Furthermore, increasing the temperature of the adsorption bed during adsorption can reduce the efficiency of the capture system. Therefore, there is a need for capture systems that use temperature changes in combination with pressure changes to optimize the efficiency and productivity of carbon dioxide adsorption and desorption.

The capture system further includes a controller configured to adjust the temperature and pressure of the adsorption bed to facilitate an increase in the amount of carbon dioxide captured by the capture system.

[0011] Figure 1 is a schematic diagram of an exemplary capture system 100 that may 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 outlet 108 are directed so that during operation, a gas flow 110 received through the inlet 106 is guided in series through each adsorption module 104 toward the outlet 108. As the gas flow 110 is guided through each adsorption module 104, the adsorption bed 102 captures CO2 from the gas flow 110 and discharges a CO2-depleted exhaust flow 112 through the outlet 108.

[0012] In general, the gas stream 110 may be any suitable gas known in the art that contains the pollutant of interest. For example, the gas stream 110 may be air, flue gas, after-combustion gas, natural gas, and / or a combination thereof. In exemplary embodiments, the gas stream 110 contains CO2. In some embodiments, the CO2 may be present in the gas stream 110 in a range of about 400 ppm to about 15 v%. In other embodiments, the CO2 may be present in the gas stream 110 in a range of about 0.04 v% to about 30 v%.

[0013] In an exemplary embodiment, the CO2 concentration in the gas flow 110 is generally highest when the gas flow 110 enters the inlet 106. As the CO2 is adsorbed by each subsequent adsorption module 104, the CO2 concentration in the gas flow 110 decreases as the gas flow 110 is guided through the adsorption modules 104a to 104d toward the outlet 108. In an exemplary embodiment, the CO2 concentration in the gas flow 110 flowing through the adsorption modules 104a to 104d is lowest at the outlet 108.

[0014] In exemplary embodiments, 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 (shown in Figure 2) defined between the contactor inlet and the contactor outlet 120 and extending from the contactor inlet 118 to the contactor outlet. In exemplary embodiments, the adsorption module 104 also includes a plate 204 (shown in Figure 2) coated in a solid form with an adsorbent 116 to facilitate the adsorption of CO2. For example, the adsorbent 116 may be, but is not limited to, a powder, a composite material mixed with a binder, a film or coating, a filled bed, and / or columnar form. In some embodiments, the adsorbent 116 may be the same within each adsorption module 104. In other embodiments, the adsorbent 116 may be different within at least one adsorption module 104. 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.

[0015] In an exemplary embodiment, the first flow 122 received through the contactor inlet 118 facilitates temperature control of the adsorbent 116 coated on the plate 204 via heat transfer between the first flow 122 flowing through the fluid circuit 202 (shown in Figure 2) and the plate 204. For example, the control temperature T of the adsorption module 104. cntl To increase or decrease the first flow 122, adjust the temperature T reg In some embodiments, the first flow 122 may be liquid. In other embodiments, the first flow 122 may be gaseous. Convection between the first flow 122 flowing through the fluid circuit 202 and the adsorbent 116 coated on the plate 204 facilitates temperature control of the adsorbent 116 without the risk of contamination that may occur from direct contact with the first flow 122.

[0016] In exemplary embodiments, the capture system 100 also includes a controller 124 that dynamically adjusts the operation of the capture system 100. For example, the controller 124 controls the temperature T of one or more adsorption modules 104, as further described herein. cntl To change and / or adjust the temperature T of the first flow 122 reg By changing this, it is possible to easily optimize CO2 capture.

[0017] The controller 124 facilitates temperature adjustment for each adsorption module 104a-104d by monitoring the temperature of the first flow 122 (shown in Figure 2) and / or the temperature of the adsorbent 116 across the plate 204. For example, the controller 124 adjusts the temperature T of the first flow 122 using the contactor sensor 126 (shown in Figure 4). reg Furthermore, the controller 124 can monitor the temperature T of at least one adsorption module 104 using the module sensor 128 (shown in Figure 4). cntl The control temperature T of at least one adsorption module 104 can be monitored. cntlAt operating conditions lower than desired, the controller 124 can selectively increase the regulated temperature T of the first stream 122, thereby indirectly increasing the temperature of at least one adsorption module 104. Alternatively, at operating conditions higher than desired, for the controlled temperature T of at least one adsorption module 104 reg the controller 124 can selectively decrease the regulated temperature T of the first stream 122, thereby indirectly decreasing the temperature of at least one adsorption module 104. cntl Generally, the regulated temperature T of the first stream 122, and thus the temperature of the adsorption module 104, can be any suitable temperature known in the art that facilitates the capture of CO2 by the systems described herein. In an exemplary embodiment, the regulated temperature T of the first stream 122 reg is monitored within each adsorption module 104a - 104d. In some embodiments, the regulated temperature T of the first stream 122

[0018] can be substantially uniform across each adsorption module 104. In other embodiments, the regulated temperature T of the first stream 122 reg may vary across different adsorption modules 104a - 104d. reg Furthermore, the controller 124 can vary the regulated temperature T of the first stream 122 within any of the adsorption modules 104a - 104d. For example, one or more of the adsorption modules 104a - 104d may include one or more module sensors 128 (shown in FIG. 4). Thus, the controller 124 can create a temperature profile that includes various values of the regulated temperature T of the first stream 122 within any or all of the adsorption modules 104a - 104d. reg The regulated temperature T of the first stream 122 reg can be any suitable temperature known in the art that facilitates the capture of CO2 by the systems described herein. In an exemplary embodiment, the regulated temperature T of the first stream 122

[0019] <l In addition, the controller 124 can vary the regulated temperature T of the first stream 122 within any of the adsorption modules 104a - 104d. For example, one or more of the adsorption modules 104a - 104d may include one or more module sensors 128 (shown in FIG. 4). Thus, the controller 124 can create a temperature profile that includes various values of the regulated temperature T of the first stream 122 within any or all of the adsorption modules 104a - 104d. reg For example, one or more of the adsorption modules 104a - 104d may include one or more module sensors 128 (shown in FIG. 4).

For example, the steam turbine may be part of a combined cycle power plant (not shown), and the extractive flow from the steam turbine is used to change the temperature of the first flow 122. In some embodiments, the extractive flow can heat the first flow 122 by convection transfer through one or more heat exchangers (not shown).

[0021] Figure 2 is a schematic diagram of an adsorption module 104 including a contactor 114 and a plate 204. In an exemplary embodiment, the contactor 114 includes a fluid circuit 202 extending between a contactor inlet 118 and a contactor outlet 120. The plate 204 is coated with an adsorbent 116 to adsorb CO2. In an exemplary embodiment, the contactor 114 and the plate 204 are located close to each other to facilitate indirect heating and / or cooling of the adsorbent coated on the plate 204.

[0022] Figure 3 is a schematic diagram of an exemplary capture system 300 that may be used to capture CO2 using multiple adsorption beds 102. In the exemplary embodiment, the system 300 includes three adsorption beds 102a-102c. The capture system 300 shown in Figure 3 is similar to the capture system 100 (shown in Figure 1), although there are differences described below, and therefore the same reference numerals are used in Figure 3 for the same components as used in Figure 1. In the exemplary embodiment, the inlets 106 of each adsorption bed 102 are connected in parallel by an inlet line 302. In some embodiments, the capture system 300 may include more or fewer than three adsorption beds 102a-102c. In the exemplary embodiment, a gas flow 110 is led through the inlet line 302, and the flow of the gas flow 110 through each respective adsorption bed 102 is controlled via a plurality of respective inlet valves 304. In an exemplary embodiment, each inlet valve 304 communicates with a controller 124, allowing the controller 124 to selectively control the flow of gas 110 from the inlet line 302 through the corresponding adsorption bed 102. For example, in an exemplary embodiment, inlet valve 304a controls the flow of gas 110 to the adsorption bed 102a.

[0023] In an exemplary embodiment, the outlets 108 of each adsorption bed 102a-102c are connected in series by an outlet line 306, and as a result, the exhaust flow 112 is led from each adsorption bed 102 through the outlet line 306 and discharged from the capture system 300. In an exemplary embodiment, the outlets 108 of each adsorption bed 102 are also connected to a pressure assembly 308 via a pressure line 310. The exhaust flow 312 is led through the pressure line 310, and the pressure of the exhaust flow 312 from each adsorption bed 102 is controlled via a plurality of pressure valves 314. Each pressure valve 314 can communicate with a controller 124, allowing the controller 124 to control the pressure of the exhaust flow 312 entering the pressure assembly 308 from the adsorption bed 102 through the pressure line 310. For example, in an exemplary embodiment, pressure valve 314a controls the pressure of the exhaust flow 312 from adsorption bed 102a through the pressure line 310, and the exhaust flow 312 is used to operate adsorption bed 102a under vacuum.

[0024] In general, the pressure assembly 308 can be any suitable pressure assembly known in the art that facilitates CO2 capture by the system described herein. In some embodiments, the pressure assembly 308 may be a vacuum pump including one or more pumps (not shown), such as a liquid ring pump, but not limited to these. In other embodiments, the pressure assembly 308 may be a blower.

[0025] The controller 124 facilitates the adjustment of the pressure in one or more adsorption modules 104 by monitoring the pressure of the exhaust flow 312 from each adsorption module 104. For example, the controller 124 adjusts the pressure P of the exhaust flow 312 using the pressure sensor 316 (shown in Figure 4). reg Furthermore, the controller 124 can monitor the control pressure P of one or more suction modules 104 using the module sensor 128 (shown in Figure 4). cntl The control pressure P of one or more adsorption modules 104 can be monitored. cntl If the operating conditions are lower than desired, the controller 124 adjusts the pressure P of the exhaust flow 312. reg This can facilitate an increase in the control pressure P of one or more adsorption modules 104, thereby increasing the pressure within at least one adsorption module 104. cntl If the operating conditions are higher than desired, the controller 124 adjusts the exhaust flow 312 pressure P reg This facilitates a reduction in pressure, thereby decreasing the pressure within one or more adsorption modules 104. The controller 124 can also monitor the concentration of CO2 in the exhaust flow 312 during desorption using a pressure sensor 316 (shown in Figure 4).

[0026] Generally, the regulating pressure P of the exhaust flow 312 reg , and the control pressure P of the adsorption module 104 thereby cntlThis can be any suitable pressure known in the art that facilitates the desorption of CO2 by the system described herein. In some embodiments, the adjustment pressure P of the exhaust flow 312 is reg This can be in the range of approximately 0.05 bar to approximately 2 bar. In other embodiments, the adjustment pressure P of the exhaust flow 312 reg This can be in the range of approximately 0.4 bar to approximately 1 bar. The controller 124 adjusts the exhaust flow pressure P of the exhaust flow 312 by changing the output of the pressure assembly 308. reg This can be easily increased. Alternatively, the controller 124 can adjust the exhaust flow 312 pressure P by changing the output from the pressure assembly 308. reg This can make it easier to reduce [the number of cases].

[0027] In exemplary embodiments, the controller 124 can control the flow of the gas stream 110 to one or more adsorption beds 102a-102c via the control of inlet valves 304a-304c. Selective use of one or more adsorption beds 102 to capture CO2 from the gas stream 110 can facilitate the optimization of the efficiency of the capture system 300. For example, the controller 124 can facilitate the optimization of CO2 capture from the gas stream 110 by using the minimum number of adsorption beds 102a-102c as needed. Thus, the flow of the gas stream 110 to one or more adsorption beds 102a-102c may be regulated by the controller 124 by selectively opening and closing at least one inlet valve 304a-304c. Furthermore, for example, the controller 124 can optimize CO2 capture from the gas stream 110 by using two or more of the adsorption beds 102a-102c in series. Therefore, the flow of gas flow 110 entering and leaving the adsorption floor 102 may be variably adjusted by the controller 124 by selectively opening and closing one or more inlet valves 304a to 304c.

[0028] In an exemplary embodiment, the controller 124 facilitates the adsorption and desorption of CO2 via the capture system 300, thereby facilitating the optimization of the amount of CO2 captured from the gas flow 110. The controller 124 controls the temperature T of one or more adsorption modules 104. cntl The control temperature T of one or more adsorption modules 104 can be variably adjusted to easily increase the amount of CO2 captured and released by the adsorbent 116. cntl Setting the temperature lower can facilitate an increase in the amount of CO2 adsorbed by the adsorbent 116. That is, in some embodiments, the adsorption performance of the adsorbent 116 is controlled by the control temperature T of one or more adsorption modules 104. cntl This may be improved by maintaining a lower temperature. Furthermore, the control temperature T of one or more adsorption modules 104a to 104d cntl By setting the temperature higher, it may be easier to increase the amount of CO2 desorbed by the adsorbent 116. That is, the control temperature T of one or more adsorption modules 104a~104d can be increased from a lower temperature used for adsorption to a higher temperature for desorption. cntl Increasing this value may improve the desorption performance of the adsorbent 116.

[0029] Control temperature T of one or more adsorption modules 104 cntl By setting the temperature to a lower level, it may be easier to increase the amount of CO2 adsorbed by the adsorbent 116 by offsetting the heat generated during adsorption. That is, the adjustment temperature T of the first flow 122 reg By indirectly cooling at least one adsorption module 104a-104d using [a specific method], it may be easier to increase the efficiency and duration of adsorption, thereby improving the adsorption performance of the adsorbent 116. Furthermore, the adjustment temperature T of the first flow 122 reg Control temperature T across one or more adsorption modules 104a to 104d using the control temperature T cntlBy changing this, it may be easier to increase the efficiency and duration of adsorption in the adsorption modules 104a to 104d, thereby improving the adsorption performance of the adsorbent 116 in the adsorption modules 104a to 104d, where the concentration of CO2 in the gas flow 110 flowing through them is highest.

[0030] The controller 124 also controls the pressure P of one or more adsorption modules 104a to 104d. cntl By adjusting the control pressure P of one or more adsorption modules 104a to 104d, it is possible to easily increase the amount of CO2 desorbed by the adsorbent 116. cntl By setting the control pressure to a lower pressure, it may be easier to increase the amount of CO2 desorbed by the adsorbent 116. In other words, the desorption performance of the adsorbent 116 depends on the control pressure P of one or more adsorption modules 104a to 104d. cntl This may be improved by lowering the pressure. In an exemplary embodiment, the controller 124 controls the control pressure P of one or more adsorption modules 104a to 104d for the desorption of CO2 from the adsorbent 116. cntl Adjust.

[0031] In an exemplary embodiment, the controller 124 controls the temperature T of one or more adsorption modules 104a to 104d. cntl and control pressure P cntl By adjusting both, the amount of CO2 captured from the gas flow 110 is easily optimized. The controller 124 controls the control temperature T of one or more adsorption modules 104a to 104d. cntl Increase the control pressure P cntl By lowering the temperature, it is possible to facilitate an increase in the amount of CO2 desorbed by the adsorbent 116. In some embodiments, the controller 124 controls the control temperature T of one or more adsorption modules 104a to 104d for a preset duration. cntl and control pressure P cntlBy adjusting this, it is possible to easily optimize the amount of CO2 captured from the gas flow 110. For example, the controller 124 controls the control temperature T of one or more adsorption modules 104a to 104d for a first predetermined duration. cntl Increase the control pressure P cntl This can reduce the control temperature T for a second predetermined duration. cntl and control pressure P cntl The corrected value can be maintained. In other embodiments, the controller 124 controls the temperature T of one or more suction modules 104a to 104d based on signals received from the contactor sensor 126, module sensor 128, and / or pressure sensor 316. cntl and control pressure P cntl The following can be adjusted. For example, at least one of the contactor sensor 126, module sensor 128, and / or pressure sensor 316 can send signals to the controller 124 indicating the start and / or end of the suction cycle and / or detachment cycle.

[0032] In some embodiments, the control temperature T cntl This can be substantially uniform across each adsorption module 104. In other embodiments, the control temperature T cntl This may differ for any one of the adsorption modules 104. For example, the controller 124 controls the control temperature T of the first adsorption module 104a in a series of adsorption modules 104 that receive the gas flow 110. cntl This makes it easier to raise the temperature. Furthermore, for example, the controller 124 controls the temperature T of the second adsorption module 104b which is coupled in series downstream from the adsorption module 104a compared to the adsorption module 104a. cntl It can reduce [the value].

[0033] Figure 4 is a schematic diagram of an exemplary control system 400 that may be used to capture CO2 in conjunction with capture systems such as the capture system 100 (shown in Figure 1) and / or the capture system 300 (shown in Figure 3). In an exemplary embodiment, the controller 124 includes memory 402 and a processor 404.
