摘要
A gas separation and utilization method includes the steps of: (a) providing an ascending flow of a liquid containing carbon dioxide gas and methane gas; (b) extracting at least a fraction of the methane gas from the liquid to provide a methane enriched gas; (c) extracting at least a fraction of the carbon dioxide gas from the liquid to provide a carbon dioxide enriched gas, which is extracted from the ascending flow of the liquid downstream of the methane enriched gas; (d) collecting the methane enriched gas; (e) feeding the carbon dioxide enriched gas as a fuel into an oxyfuel power generation system; (f) generating power from the oxyfuel power generation system; and (g) expelling an exhaust from the oxyfuel power generation system, wherein the exhaust comprises carbon dioxide and water vapor. A system configured to perform the method and a grid balancing method using the system are also disclosed.
