Abstract

A COrecovery unitA according to a first embodiment has a COabsorber that removes COin flue gas by bringing the flue gas containing COinto contact with a COabsorbent, and a regeneratorthat diffuses COin a rich solutionhaving absorbed COin the COabsorber. The COrecovery unitA includes a first compressor-to a fourth compressor-that compress COgasdischarged from the regenerator, a dehydrating columnthat reduces moisture in the COgasby bringing the COgasinto contact with a dehydrating agent, a combustion removal unitthat removes the dehydrating agentmixed in the COgasin the dehydrating column, and a heat exchangerthat performs heat exchange between the COgasdischarged from the third compressor-and the COgasdischarged from the dehydrating column
