CARBON DIOXIDE CHEMICAL ABSORPTION SYSTEM INSTALLED WITH VAPOR RECOMPRESSION EQUIPMENT

摘要

An exhaust gas treatment system, comprising: CO2 chemical absorption equipment having an absorption tower for absorbing carbon dioxide (CO2) in combustion exhaust gas discharged from a combustion device using an absorption liquid mainly composed of an amine compound, and a regeneration tower for removing CO2 from the absorption liquid having absorbed the CO2 and regenerating the absorption liquid; a flash tank for depressurizing and flash-evaporating absorption liquid taken out from a lower part of the regeneration tower; vapor recompression equipment for compressing the vapor created by the flash tank; a temperature control device for adjusting to a predetermined temperature the vapor compressed by the vapor recompression equipment; and pipework for supplying to the regeneration tower the vapor adjusted to the predetermined temperature by the temperature control device.
