Rotational absorber device and method for scrubbing an absorbate from a gas

A rotational absorber device for scrubbing an absorbate from a gas, the device comprising:

• a housing having a gas inlet;
• a gas outlet;
• at least one absorbent liquid inlet;
• means for providing a sustained flow of absorbent liquid to the at least one absorbent liquid inlet;
• and
• at least one absorbent liquid outlet;
• at least one rotor mounted for rotation in said housing and fluidly connecting to the inlets and outlets, the at least one rotor comprising a plurality of scrubbing channels extending axially and parallel to a common central axis of rotation, wherein the channels are circumferentially enclosed by walls over an entire axial length of the at least one rotor, the at least one rotor being disposed between the at least one absorbent liquid inlet and the at least one absorbent liquid outlet;
• wherein the device further comprises:
• means for rotating the at least one rotor causing an absorbent liquid fed to the at least one rotor to be at least partly separated from a gas fed to the rotor, and exit the at least one rotor in the form of absorbent liquid droplets that are propelled radially outwards with respect to the common central axis of rotation of the at least one rotor towards the at least one absorbent liquid outlet where the absorbent liquid is discarded;
• and
• wherein the gas inlet and the at least one absorbent liquid inlet are located on one side of the at least one rotor, and the gas outlet and the at least one absorbent liquid outlet are located on an opposite side of the at least one rotor.
