Abstract
A COrecovery unit includes a COabsorber that brings a gas having a low COconcentration into countercurrent contact with a COabsorbent to remove COfrom the gas. The COrecovery unit further includes a first absorbent circulation line that supplies a COabsorbent from a first COabsorption section as a first circulation solution to an upper side of a first COabsorption section; a second absorbent circulation line that supplies a COabsorbent from a second COabsorption section as a second circulation solution to an upper side of a second COabsorption section; and an absorbent discharge line that discharges a part of the first circulation solution from the first absorbent circulation line and supply the part of the first circulation solution as a discharged solution to the second absorbent circulation section.
