METHOD OF SEPARATING CO2 FROM A GAS FLOW, CO2 SEPARATING DEVICE FOR CARRYING OUT THE METHOD, SWIRL NOZZLE FOR A CO2 SEPARATING DEVICE

摘要

A method is provided for separating CO₂ from an exhaust gas flow of a combustion process. The method includes: compressing the gas flow and cooling the compressed gas flow. The method also includes feeding the cooled gas flow to a swirl nozzle and separating the CO₂ from the gas flow in the swirl nozzle. The method also includes discharging the CO₂ which is separated in the swirl nozzle from the swirl nozzle for separate further treatment. A CO₂ separating device is also provided that separates CO₂ from an exhaust gas flow of a combustion process that operates with fossil fuels. The device includes a swirl nozzle which is exposed to through-flow of the gas flow, a compressor located upstream or downstream of the swirl nozzle, and a plurality of cooling devices which are provided upstream of the swirl nozzle for cooling of the gas flow which comes from the compressor.
