Abstract
Provided are a COabsorber that reduces COcontained in flue gas; a regenerator that reduces COcontained in rich solvent absorbing COto regenerate the rich solvent, so that lean solvent having the COreduced in the regenerator is reused in the COabsorber; a heat exchanger that allows the rich solvent to exchange heat with the lean solvent; and a controller that controls to extract rich solvent portion that is part of the rich solvent, to allow the rich solvent portion to bypass the heat exchanger, and to be supplied into the top of the regenerator without exchanging heat so as to minimize a sum of an enthalpy that is taken out of the regenerator as COgas accompanying steam and an enthalpy of the lean solvent after heat exchange with the rich solvent in the heat exchanger.
