Abstract
A COrecovery apparatus according to the present invention includes: an absorber () that brings CO-containing flue gas (A) into counter-current contact with COabsorbent () to reduce CO, and a regenerator () that regenerates rich solution () that has absorbed CO, in which lean solution () having COreduced in the regenerator () is reused in the absorber (). The absorber () further includes a COabsorbing unit () that recovers COcontained in the flue gas (A), and the COabsorbent () that has absorbed COis extracted from a rich side of the COabsorbing unit () to exterior, cooled, and then supplied to a position nearer to a lean side of the absorber () with respect to the position at which the COabsorbent () is extracted.
