Abstract: A capture vessel is provided that is configured to capture carbon dioxide (CO2) according to a thermal swing adsorption (TSA) process. The capture vessel includes capture media that are configured to adsorb CO2 from an exhaust gas during a CO2 capture stage to produce a first N2 gas that exits the capture vessel, receive a mixed stream of CO2 and water vapor during a wet regeneration stage, adsorb water from the mixed stream of CO2 and water vapor and release adsorbed CO2 during the wet regeneration stage to produce a CO2 stream, receive a first heated N2 gas and release adsorbed water due to evaporation caused by the first heated N2 gas during a drying stage, and receive a cooled gas during a cooling stage such that an absorption capacity of the capture media for CO2 capture is increased for a next CO2 capture stage.

Abstract: A capture vessel is provided that is configured to capture carbon dioxide (CO2) according to a thermal swing adsorption (TSA) process. The TSA process includes a cyclical sequence including at least a CO2 capture stage, a regeneration stage, and a cooling stage. The capture vessel includes capture media arranged inside the capture vessel, and an inter-exchanger arranged inside the capture vessel and thermally coupled to the capture media. The capture media are configured to adsorb CO2 from an exhaust gas during the CO2 capture stage to produce a nitrogen (N2) gas that exits the capture vessel. The inter-exchanger is configured to, during the CO2 capture stage, circulate a coolant within the capture vessel to regulate a temperature of the capture media.

Abstract: A carbon capture system for carbon dioxide (CO2)-thermal swing adsorption (TSA) includes an engine configured to produce a hot exhaust; a plurality of capture vessels that are configured to be respectively cycled through a plurality of stages of a CO2-TSA process; an N2 heat exchanger configured to receive the hot exhaust; and an N2 turbocharger coupled to the N2 heat exchanger. The N2 turbocharger is configured to receive N2 gas from a first capture vessel, heat the N2 gas via the N2 heat exchanger through a thermal exchange with the hot exhaust to produce a heated N2 gas, and provide the heated N2 gas to a second capture vessel in order to dry capture media of the second capture vessel.

Abstract: Disclosed is an improved method and system of operating the semi-closed cycle, which both reduces parasitic loads for oxygen generation and for gas clean up, while also reducing, capital cost of the gas clean up plant (reduced drying requirement) and of the oxygen plant (enabling membranes vs. mole sieves). The invention is applicable to piston or turbine engines, and results in a near fully non-emissive power system via the Semi-Closed Cycle (SCC), in a manner which both captures carbon in the form of carbon dioxide, CO2, and in a manner which improves the efficiency and cost effectiveness of prior disclosures. The captured carbon is of a purity and pressure directly suitable for Enhanced Oil Recovery (EOR), sequestration, or industrial use.
