摘要：
A method for separating CO2 from C2 to C5 alkanes includes introducing a first stream including C2 to C5 alkanes and CO2 into a first separation zone, the first separation zone including a hydrocarbon solvent, and separating the first stream into a recycle stream and a second stream in the first separation zone. The recycle stream including CO2 and one or more of CO, H2, and CH4, and the second stream including C2 to C5 alkanes. The method further includes introducing the second stream into a second separation zone, and separating the second stream into a third stream and a fourth stream, wherein the third stream includes C2 alkanes and the fourth stream includes C3 to C5 alkanes.
