Abstract
A carbon capture system can include a plurality of CO2 thermal swing adsorption (TSA) beds. The plurality of CO2 TSA beds can include at least a first TSA bed, a second TSA bed, and a third TSA bed configured to capture CO2 within a capture temperature range and to regenerate the captured CO2 at a regeneration temperature range above the capture temperature range. The carbon capture system can include a plurality of valves and associated flow paths configured to allow switching operational modes of each of the first, second, and third TSA beds.
Claims20
A carbon capture system, comprising:
- a plurality of thermal swing adsorption (TSA) beds, including at least:
- a first TSA bed configured to capture CO2 within a capture temperature range and to regenerate captured CO2 at a regeneration temperature range above the capture temperature range;
- a second TSA bed configured to capture CO2 within the capture temperature range and to regenerate captured CO2 at the regeneration temperature range;
- and
- a third TSA bed configured to capture CO2 within the capture temperature range and to regenerate captured CO2 at the regeneration temperature range above the capture temperature range;
- a plurality of valves and associated flow paths configured to allow switching operational modes of each of the first TSA bed, the second TSA bed, and the third TSA bed;
- and
- a control module configured to control the plurality of valves to provide continuous operation such that, simultaneously, at least one of the plurality of TSA beds is operated in a capture mode to remove CO2 from an exhaust flow and to output a nitrogen flow, at least one of the plurality of TSA beds is used in a heated regeneration mode to release CO2 into a production flow, and at least one of the one of the plurality of TSA beds is operated in a cooling mode to be cooled by a cooling flow.
