A rotating packed bed RPB (1) comprises a first and second packed bed (3, 4) both arranged on the same rotatable shaft (2). A gas is directed via a gas inlet (G in ) through the first packed bed (3) in co-current flow with a liquid in a radially outward direction towards the outer radius of the packed bed (3). The liquid enters the first packed bed via a first liquid inlet (5a). The gas exiting the first packed bed (3) is directed to the second packed bed (4) and forced through it in a radially inward direction in counter-current flow with a liquid, which enters through a second liquid inlet (5b). The arrangement allows an operation of the rotating packed bed with less energy compared to RPBs of the prior art operating in counter-current flow only. The apparatus allows low-cost design and a high design flexibility. |
