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： A CO2 recovery system according to the present invention includes: a cooling tower that uses cooling water to cool a CO2-containing exhaust gas discharged from industrial equipment such as a boiler or a gas turbine; a CO2 absorber that brings the cooled CO2-containing exhaust gas into contact with a CO2-absorbent that absorbs CO2, thereby removing the CO2 from the exhaust gas; and a first absorbent regenerator and a second absorbent regenerator that release CO2 from a CO2-absorbent that has absorbed CO2 (rich solution), thereby regenerating the CO2-absorbent. A second lean solution at the outlet of the second absorbent regenerator is subjected to vacuum flash vaporization, and the resulting vapor is inputted to the first absorbent regenerator.
