Abstract
A COrecovery system according to the present invention includes: a cooling tower that uses cooling water to cool a CO-containing exhaust gas discharged from industrial equipment such as a boiler or a gas turbine; a COabsorber that brings the cooled CO-containing exhaust gas into contact with a CO-absorbent that absorbs CO, thereby removing the COfrom the exhaust gas; and a first absorbent regenerator and a second absorbent regenerator that release COfrom a CO-absorbent that has absorbed CO(rich solution), thereby regenerating the CO-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.
