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).
