| abstract |
An energy-efficient method of recovering carbon dioxide (CO 2 ) in a liquid state from a high-pressure gas stream is provided. The method includes cooling, condensing, and/or separating CO 2 from a high-pressure gas stream and further purifying the resulting liquid CO 2 in a purification zone to thereby provide a purified CO 2 product. The purified liquid CO 2 product may then be pumped to a higher pressure for further utilization and/or sequestration for industrial or environmental purposes. |
