ABSTRACT:
For separating CO.sub.2 from CO.sub.2 -containing gases, especially stack gases and/or blast furnace gases, dimethylformamide is employed as a physical scrubbing medium to ensure high CO.sub.2 purity. After absorption of CO.sub.2, the DMF is regenerated and returned into the scrubbing stage. Dimethylformamide is utilized as the scrubbing medium.
