Abstract

A gas treatment system includes an absorber, a liquid separator, a regenerator, a circulation mechanism and a heat transfer apparatus. The absorber contacts the gas with the treatment liquid. The liquid separator separates the treatment liquid having been in contact with the gas into a first phase portion having a high content of the acidic compound and a second phase portion having a low content of the acidic compound. The regenerator heats the first phase portion to eliminate the acidic compound from the first phase portion. The circulation mechanism recycles the second phase portion and the treatment liquid from which the acidic compound has been eliminated by the regenerator, in the absorber as a treatment liquid with which the gas is to be contacted. The heat transfer apparatus transfers heat from the treatment liquid discharged by the absorber and from the gas having undergone separation of the acidic compound, to the treatment liquid in the regenerator.
