A system (10) for processing recirculation air discharged from an aircraft cabin (11) comprises a recirculation air supply line (12) which is connectable to the aircraft cabin (11) so as to allow a flow of recirculation air discharged from the aircraft cabin (11) therethrough. An absorber (16) is connected to the recirculation air supply line (12) and is adapted to remove CO 2 from the recirculation air flowing through the recirculation air supply line (18) by absorption of CO 2 in an absorption medium is provided. A recirculation air discharge line (46) is connected to the absorber (16) and is connectable to the aircraft cabin (11) so as to allow a flow of absorption treated recirculation air exiting the absorber (16) to the aircraft cabin (11). Finally, an air processing device (48) is disposed in the recirculation air discharge line (46), wherein the air processing device (48) is connected to an O 2 source (42) and is adapted to enrich the recirculation air exiting the absorber (16) with O 2 . |
