Patent ID: 8475566

Claim:
A method for recovery of CO 2 from a CO 2 -containing gas comprising the steps of: a. feeding a plant with a pressurised CO 2 -containing gas and/or compressing the CO 2 -containing gas during feeding, b. cooling the compressed gas obtained in step a, c. separating the gas obtained in step b by a condensation procedure, by which said gas is separated into a CO 2 -rich liquid (L 1 ) and a CO 2 -containing gas (G 1 ), d. absorbing the gas G 1 obtained in step c with a physical liquid absorbing agent selected from the group consisting of SELEXOL, methanol, propylene carbonate and mixtures thereof, by which the gas G 1 is separated into a liquid (L 2 ) and a CO 2 -poor gas (G 2 ), e. separating the liquid L 2 obtained in step d in order to obtain a CO 2 -containing gas (G 3 ) and a liquid (L 3 ), f. compressing the gas G 3 obtained in step e in order to obtain a CO 2 -containing gas (G 4 ), g. distilling the liquid L 1 obtained in step c in order to recover liquid CO 2 (L 5 ) and a gas (G 5 ) substantially free of CO 2 , and h. processing gas G 5 for recycle.
