Apparatus for continuous carbon dioxide absorption
First Claim
1. Apparatus for removing carbon dioxide from a stream of air or other gas, said apparatus including:
- a substantially vertical gas absorption reactor which contains a plurality of loosely packed mixing units submerged in a carbon dioxide absorbent liquid;
a gas inlet into the reactor, said inlet being arranged to admit in use an incoming stream of gas at or near the base of the reactor, and a gas outlet at or adjacent the top of the reactor through which the outgoing stream of treated gas leaves the reactor in use;
said reactor further being provided with a liquid outlet and a liquid inlet in the wall of the reactor, the liquid outlet being located higher up the wall of the reactor than the liquid inlet;
a regenerator which incorporates heating means and which is provided with an inlet and the outlet and a carbon dioxide vent;
the regenerator inlet being connected to the liquid outlet from the reactor, and the regenerator outlet being connected to the liquid inlet to the reactor.

Abstract
Apparatus for removing carbon dioxide from a stream of air or other gas, which includes a vertical gas absorption reactor containing loosely packed mixing units submerged in a carbon dioxide absorbent liquid; gas to be treated is admitted at or near this base of the rector, is broken into small bubbles by the mixing units, and passes through the absorbent liquid to remove a high percentage of carbon dioxide; treated gas leaves from the top of the reactor, a regenerator associated with the reactor continually or intermittently regenerates the absorbent liquid and is arranged to receive absorbent liquid to be treated through an outlet from the reactor which is located higher up the wall of the reactor than the inlet for returning treated liquid to the reactor.
