Publication number: 20240066465Abstract: A ship with a flue gas carbon dioxide capture and storage plant has a main engine such as a slow running diesel engine providing flue gas. The flue gas is led via a flue gas heat exchanger with a thermal fluid exit to a re-boiler and arranged for cooling said flue gas. Further cooled flue gas is led into a turbine compressor compressing it up to a compressed flue gas. A combustion chamber is provided with a fuel feed and a pre-mix gas burner for afterburning said compressed flue gas which also burns remaining methane from the diesel engine, resulting in hot afterburned compressed flue gas enriched in CO2. The CO2-absorber (20) leading said CO2-enriched absorber solution to a CO2-stripper (21), operating at e.g. 1 Bar and exporting CO2 to a CO2-compressor (26) to a CO2-export line (28) to onboard CO2 pressure tanks.Type: ApplicationFiled: January 12, 2022Publication date: February 29, 2024Inventors: Henrik Fleischer, Knut Erik Børseth

Patent number: 11701613Abstract: A method and a plant for capturing CO2 from an incoming flue gas. The flue gas can be exhaust gas from coal and gas fired power plants, cement factories or refineries. The incoming exhaust gas is cooled, mixed with air and compressed, and thereafter introduced into a combustion chamber together with gas and/or liquid fuel. Part of the combustion is achieved by separate burners with cooling/combustion air feed with a volume equal to the volume of CO2 captured. Said burners will elevate the temperature in the combustion chamber allowing combustion of exhaust gas with low oxygen content. CO2 is captured at high partial pressure before expansion by the gas turbine to produce power and generate steam in the heat recovery unit. The gas turbine will operate with high efficiency close to design parameters with respect to inlet temperature, pressure and flow.Type: GrantFiled: March 9, 2018Date of Patent: July 18, 2023Assignee: KARBON CCS LTDInventors: Knut Børseth, Henrik Fleischer

Publication number: 20230173430Abstract: A CO2 capture system includes an intake for CO2-rich exhaust gas to a compressor and one or more outlets for compressed, first CO2-rich gas to a manifold to a shell enclosing parts of a combustion chamber. The combustion chamber has burners to burn fuel and compressed air from a fuel line and an air supply pipe, to form a second, CO2 rich gas. The wall in the combustion chamber has slits to let in the compressed CO2-rich gas to mix with and cool the other CO2-rich gas formed in the combustion chamber of a third CO2-rich exhaust gas. A heat exchanger operates under high pressure and heat exchanges the third, hot CO2-rich exhaust gas from the combustion chamber with returning CO2-poor exhaust gas from a CO2 extraction plant. The returned, heated CO2-poor exhaust gas is led back to an expander driving the compressor and the CO2 extraction plant.Type: ApplicationFiled: April 14, 2021Publication date: June 8, 2023Inventors: Knut Borseth, Henrik Fleischer
