Beschreibung
Zusammenfassung:	An exhaust gas treatment system comprising: a CO2 chemical absorption equipment comprising an absorption column which absorbs carbon dioxide (CO2) in a combustion exhaust gas discharged from a combustion device with the use of an absorbing solution comprising an amine compound as a main component and a regeneration column which regenerates the absorbing solution by desorbing CO2 from the absorbing solution which absorbed CO2; a flash tank which depressurizes the absorbing solution withdrawn from a lower part of the regeneration column to flash-evaporate the absorbing solution; a vapor recompression equipment which compresses the vapor generated by the flash tank; a temperature control device which adjusts the vapor compressed by the vapor recompression equipment to be within a predetermined temperature; and a piping for feeding the vapor adjusted to the predetermined temperature by the temperature control device to the regeneration column.
