System and method of CO2 thermal swing adsorption with wet regeneration and hot drying

A carbon capture system for carbon dioxide (CO2)-thermal swing adsorption (TSA), the carbon capture system comprising:

• an engine configured to produce a hot exhaust;
• an adsorption inlet arranged downstream from the engine and configured to receive a cold exhaust comprising a mixture of CO2 and nitrogen (N2), wherein the cold exhaust is derived from the hot exhaust using one or more first heat exchangers;
• a plurality of capture vessels that are configured to be respectively cycled through a plurality of stages of a CO2-TSA process, including a CO2 capture stage, a regeneration stage, a drying stage, and a cooling stage, wherein the plurality of capture vessels are respectively coupled to the adsorption inlet for receiving the cold exhaust during the CO2 capture stage,
• wherein, while a first capture vessel of the plurality of capture vessels is configured in the drying stage, a second capture vessel of the plurality of capture vessels is configured in the CO2 capture stage, and
• wherein the second capture vessel is configured to, during the CO2 capture stage, receive the cold exhaust and absorb CO2 from the cold exhaust to produce a first N2 gas;
• an N2 heat exchanger configured to receive the hot exhaust;
• and
• an N2 turbocharger coupled to the N2 heat exchanger,
• wherein the N2 turbocharger is configured to, while the second capture vessel is configured in the CO2 capture stage and the first capture vessel is configured in the drying stage, receive the first N2 gas from the second capture vessel, heat the first N2 gas via the N2 heat exchanger through a thermal exchange with the hot exhaust to produce a first heated N2 gas, and provide the first heated N2 gas to the first capture vessel, and
• wherein, while the first capture vessel is configured in the drying stage, capture media of the first capture vessel are dried via the first heated N2 gas.
