Document Type and Number:
Japanese Patent JP5591083
Kind Code:
B2
Abstract:
A CO2recovery system (10,10A to 10D) according to the present invention includes: a cooling tower (14) that uses cooling water (13) to cool a CO2-containing exhaust gas (12) discharged from industrial equipment such as a boiler (11) or a gas turbine; a CO2absorber (16) that brings the cooled CO2-containing exhaust gas (12) into contact with a CO2-absorbent (15) that absorbs CO2, thereby removing the CO2from the exhaust gas (12); and a first absorbent regenerator (18-1) and a second absorbent regenerator (18-2) that release CO2from a CO2-absorbent that has absorbed CO2(rich solution) (17), thereby regenerating the CO2-absorbent (15). A second lean solution (15B) at the outlet of the second absorbent regenerator is subjected to vacuum flash vaporization, and the resulting vapor (52) is inputted to the first absorbent regenerator (18-1).
