Effluent gases (1) are first cooled and then delivered (2) to an eductor which pulls the gases into the recycled water/absorbent (8). The CO2 absorption occurs during 2-phase flow in the downcomer (3). The non-absorbed N2, Ar and excess O2 come out of the two-phase stream (4) in the separator. The water containing the dissolved CO2 (5) is then pumped up the riser (6). As the water moves up the riser, the pressure is continually diminishing and the CO2 comes out of the water (7). And the water is recycled (8).
