A method and a plant for producing liquid C02 out of combustion flue gases wherein the flue gas is partially condensed in a single stage phase separation, the single stage phase separation comprising at least one heat exchanger (11, 17) and a separation drum (19), wherein the at least one heat exchanger (11, 17) is cooled by expanded offgas (23) and expanded liquid C02 (3.3) and wherein a first part of the expanded C02 (3.3) is separated after having passed the at least one heat exchanger (17) into liquid C02 and gaseous C02 in an additional separation drum (33), wherein the gaseous C02 (3.4) and the liquid C02 (3.5) of the additional separation drum (33) are expanded to a first pressure level (flag 7d') wherein a second part of the liquid C02 (3.6) of the separation drum (33) is expanded to a second pressure level (flag 7e') for cooling the flue gas in the at least one heat exchanger (17). |
