Title:
CO2 RECOVERY DEVICE AND METHOD FOR RECOVERING CO2
Document Type and Number:
WIPO Patent Application WO/2011/105120
Kind Code:
A1
Abstract:
Disclosed is a CO2 recovery device which includes: an absorption tower in which CO2 contained in a discharge gas (101) discharged from a combustion system (50) is absorbed into an absorption liquid and removed; a regeneration tower in which the absorption liquid that has absorbed CO2 is heated to release the CO2 and regenerate the absorption liquid and from which the regenerated absorption liquid is supplied to the absorption tower; and a regeneration heater with which steam (106) heated in the combustion system (50) is used to heat the absorption liquid in the regeneration tower and from which condensed water (106a) resulting from the heating is returned to the combustion system (50). The device is equipped with a condensed water/discharge gas heat exchanger (57) in which the condensed water (106a) to be returned to the combustion system (50) from the regeneration heater is heated by heat exchange with the discharge gas (101) flowing through the flue (51) of the combustion system (50).
