The decarbonized flue gas is discharged from the top of the absorption tower 1. The absorbent that absorbs CO2 is heated by the lean-rich liquid heat exchanger and enters the regeneration tower to desorb CO2. The desorbed CO2 is cooled together with the water vapor, and the water is removed to obtain high-purity CO2 gas, which is used in other places where CO2 is needed. The absorbent that desorbs CO2 is a lean liquid, which flows out from the bottom of the regeneration tower, and after heat exchange in the lean-rich liquid heat exchanger, it enters the absorption tower 1 to circulate and absorb CO2.

The absorbent that absorbs CO2 is heated by the lean-rich liquid heat exchanger and enters the regeneration tower to desorb CO2. The desorbed CO2 is cooled together with the water vapor, and the water is removed to obtain high-purity CO2 gas, which is used in other places where CO2 is needed.
