    摘要: A reclaiming apparatus 106 includes: a sealed container 106a that is an absorbent reservoir for storing therein a part of an absorbent that has absorbed CO2 in flue gas, and a heater that heats the absorbent stored in the sealed container 106a. The reclaiming apparatus 106 distributes a part of the absorbent stored in the sealed container 106a, and brings the distributed absorbent into counter-current contact with steam. Because a part of the absorbent stored in the absorbent reservoir is brought into counter-current contact with the steam, absorbent component contained therein becomes volatilized, and is separated from depleted materials. In this manner, the absorbent component can be extracted from the depleted materials, and a loss of the absorbent can be reduced.

    摘要: Provided are a CO2 absorber that reduces CO2 contained in flue gas; a regenerator that reduces CO2 contained in rich solvent absorbing CO2 to regenerate the rich solvent, so that lean solvent having the CO2 reduced in the regenerator is reused in the CO2 absorber; 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 by pass 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 CO2 gas accompanying steam and an enthalpy of the lean solvent after heat exchange with the rich solvent in the heat exchanger.
