Title:
SYSTEM AND METHOD FOR RECOVERING HEAT FROM CO2 RECOVERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/096250
Kind Code:
A1
Abstract:
Disclosed is a system for recovering heat from a CO2 recovery device (55) that includes an absorption tower in which CO2 contained in a combustion gas (101) discharged from a boiler (51) is absorbed into an absorption liquid and removed and a regeneration tower in which the CO2 is released from the absorption liquid that has absorbed CO2, thereby rendering the absorption liquid reusable in the absorption tower, the system being equipped with: a Ljungstrom heat exchanger (57) which performs heat exchange between a combustion gas (101) that has been discharged from the boiler (51) and has not yet reached to the CO2 recovery device (55) and air for combustion (102) to be supplied to the boiler (51); and an air preheater (58) in which the air for combustion (102) that has not yet reached to the Ljungstrom heat exchanger (57) is preheated by means of waste heat taken out of the CO2 recovery device (55).
