Abstract: A method for separating carbon dioxide (CO 2 ) from a fluid stream comprising CO 2 and a liquid solvent is provided. The method includes receiving the fluid stream at a first flashing means to obtain a first CO 2 stream and a first CO 2 lean fluid stream enriched in the liquid solvent in comparison with the fluid stream. Further, the method also includes receiving the first CO 2 lean fluid stream at a second flashing means to obtain a second CO 2 stream and a second CO 2 lean fluid stream that is enriched in the liquid solvent in comparison with the first CO 2 lean fluid stream.
