Claim 13:
14. A carbon capture system, comprising:
a plurality of thermal swing adsorption (TSA) beds that include a 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 control module configured to control switching operational modes, associated with flow paths, 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; and
a production stream circulator subsystem selectively connected to the TSA bed and configured to circulate the production flow to regenerate additional CO2 from the TSA bed to increase CO2 concentration in the production flow.
