Patent ID: 8535428

Claim:
A system for recovering carbon dioxide from flue gas, comprising: an absorber that brings CO 2 absorbent that absorbs CO 2 contained in flue gas exhausted from industrial facilities into contact with the flue gas to remove CO 2 from the flue gas; a regenerator that strips CO 2 from CO 2 absorbent that is fed from the absorber through a first feed line and has absorbed the CO 2 to regenerate CO 2 absorbent; at least two falling film reboilers that draw off CO 2 absorbent from near a bottom of the regenerator and reheats CO 2 absorbent via steam; a first liquid-vapor separator that separates CO 2 absorbent reheated by the falling film reboilers into CO 2 absorbent and vapor containing CO 2 ; and a second feed line for supplying separated CO 2 absorbent to the absorber.
