The present invention relates to a system 1 for accelerated absorption and desorption of C02 comprising an absorber 100 for absorbing C02 from a gas stream 10 by use of absorption liquid 2 and a desorber 200 for desorbing C02 from C02 rich absorption liquid 3. The absorber 100 comprises a rotatable main cylinder having an absorption section 105 provided with rotatable means for disintegration of droplets 111 of absorption liquid and means for rotating the absorber, such that absorption liquid droplets are moved by aid of centrifugal force in a cross flow-direction in relation to the gas stream and being atomized by the means for disintegration of droplets whereby C02 is absorbed from the gas stream by the absorption liquid droplets. The desorber 200 is connected to the absorber 100 to receive C02 rich absorption liquid 3, and the desorber 200 is rotatable and comprises a desorption chamber 202 provided with a rotatable heat exchanger and means for rotating the desorber, such that the absorption liquid droplets are moved by aid of centrifugal force through the heat exchanger whereby the absorption liquid droplets are heated and C02 is desorbed and separated from the absorption liquid droplets, and lean absorption liquid 2 is circulated to the absorber. The present invention also relates to a process for accelerated absorption and desorption of C02.
