Publication number: 20240058742Abstract: 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.Type: ApplicationFiled: July 28, 2023Publication date: February 22, 2024Applicant: Enhanced Energy Group LLCInventor: Paul M.

Patent number: 11834986Abstract: 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.Type: GrantFiled: June 27, 2022Date of Patent: December 5, 2023Assignee: Enhanced Energy Group LLC.Inventor: Paul M.

Patent number: 8749079Abstract: A compact Wankel expander-alternator combination is provided. The combination includes a stationary outer housing that has embedded stator coils and a rotating inner housing having corresponding magnets disposed around the housing with the magnet/coil interaction generating power. Within the rotating housing, a three-sided rotor turns within a two lobed Wankel cavity, powered by working fluid acting on the rotor. The rotating housing and the rotor each circumscribe a stationary shaft. The shaft has an eccentric lobe about which the rotor turns on a bearing disposed between the rotor and the lobe. The rotating housing turns on bearings supported by the stationary shaft. The rotor and rotating housing are linked so that as the rotor turns in response to the working fluid force, the housing turns at a higher speed the speed ratio being preselected to achieve the desired output energy.Type: GrantFiled: April 1, 2011Date of Patent: June 10, 2014Assignee: The United States of America as represented by the Secretary of the NavyInventors: Paul M.
