| 摘要 |
The invention relates to a method for producing a carbon dioxide-rich gas mixture (44) wherein a hydrocarbon-containing fuel (21) is burned in a combustion chamber of a gas engine (10) in a gas atmosphere, and the exhaust gas (14) of the gas engine (10) is processed into the carbon dioxide-rich gas mixture (44). The gas atmosphere in the combustion chamber has an oxygen content (33) that corresponds to 0.9 to 1.1 times the amount of oxygen required for complete combustion of the hydrocarbon-containing fuel (21), and the gas atmosphere has a volumetric ratio of nitrogen to oxygen (33) in that is less than 3.5 to 1. The invention also relates to an apparatus for producing the carbon dioxide-rich gas mixture (44), and a method and apparatus for enhanced oil recovery using the method and apparatus for producing the carbon dioxide-rich gas mixture (44).
