摘要： A CO 2 recovery unit (10A; 10B; 10C) for recovery and removal of CO 2 in a CO 2 -containing flue gas 11A that contains CO 2 using a CO 2 -absorbent 12 within a CO 2 absorber 13 is provided. The CO 2 absorber 13 includes a CO 2 -absorbing unit 13A for the absorption of CO 2 in a CO 2 -containing flue gas, a main water rinsing unit 13C that is provided on a gas flow downstream side of the CO 2 -absorbing unit 13A and that uses rinsing water 20 to recover the accompanying CO 2 -absorbent while cooling decarbonated flue gas, and a preliminary water rinsing unit 13B provided between the CO 2 -absorbing unit 13A and the main water rinsing unit 13C. A portion 20a of the rinsing water 20 containing the CO 2 -absorbent that is circulated in the main water rinsing unit 13C is withdrawn and is subjected to preliminary water rinsing in the preliminary water rinsing unit 13B. The preliminary rinsing water is allowed to meet with a CO 2 -absorbent 12 while allowing the rinsing water to directly flow down on the CO 2 -absorbing unit 13A side.
