Apparatus for recovering CO2 and method of recovering CO2

摘要

A CO 2 recovery apparatus according to the present invention includes: an absorber (1003) that brings CO 2 -containing flue gas (1001A) into counter-current contact with CO 2 absorbent (1002) to reduce CO 2 , and a regenerator (1005) that regenerates rich solution (1004) that has absorbed CO 2 , in which lean solution (1006) having CO 2 reduced in the regenerator (1005) is reused in the absorber (1003). The absorber (1003) further includes a CO 2 absorbing unit (1010) that recovers CO 2 contained in the flue gas (1001A), and the CO 2 absorbent (1002) that has absorbed CO 2 is extracted from a rich side of the CO 2 absorbing unit (1010) to exterior, cooled, and then supplied to a position nearer to a lean side of the absorber (1003) with respect to the position at which the CO 2 absorbent (1002) is extracted.
