To include an absorber (1006) that brings CO 2 absorbent that absorbs CO 2 contained in flue gas (1002) into contact with the flue gas to remove CO 2 from the flue gas, a regenerator (1008) that strips CO 2 from CO 2 absorbent (rich solution), which is fed from the absorber through a first feed line L 1 and has absorbed CO 2 , to regenerate CO 2 absorbent, thereby acquiring regenerated CO 2 absorbent (lean solution) (1009), falling film reboilers (1101-1 and 1101-2) that draw off CO 2 absorbent (amine solution) (1033) from near the bottom of the regenerator and reheats regenerated CO 2 absorbent via steam (1031), a first liquid-vapor separator (1103) that separates the CO 2 absorbent reheated by the falling film reboilers into regenerated CO 2 absorbent in which CO 2 has been removed and vapor containing CO 2 and a second feed line L 2 for supplying the separated regenerated CO 2 absorbent to the absorber. |
