Patent ID: 7985278

Claim:
A method for separating CO 2 from an exhaust gas flow of a combustion process which operates with fossil fuels, comprising: a. compressing the gas flow; b. precooling the compressed gas flow in a heat exchanger ( 14 ), which operates with cooling water, by at least one refrigeration cycle (CC 1 , CC 2 ) which operates with a compressor ( 24 , 25 ), condenser ( 21 , 26 ), expansion valve ( 22 , 27 ) and evaporator ( 15 , 16 ); c. feeding the cooled gas flow to a swirl nozzle ( 17 , 17 ′, 17 ″), and separating the CO 2 from the gas flow in the swirl nozzle ( 17 , 17 ′, 17 ″); and d. discharging the CO 2 which is separated in the swirl nozzle ( 17 , 17 ′, 17 ″) from the swirl nozzle ( 17 , 17 ′, 17 ″) for separate further treatment.
