GAS TREATMENT SYSTEM AND GAS TREATMENT METHOD

摘要

A gas treatment system is provided with an absorber, a liquid separator, a regenerator, a circulation mechanism, and a heat transfer device. The absorber brings gas to be treated into contact with a treatment solution. The liquid separator separates the treatment solution that has made contact with the gas to be treated into a first phase part wherein the acidic compound content is large and a second phase part wherein the acidic compound content is small. The regenerator heats the first phase part and releases the acidic compound from the first phase part. The circulation mechanism circulates the second phase part and the treatment solution from which the acidic compound has been released by the regenerator as treatment solution to be brought into contact with gas to be treated in the absorber. The heat transfer device transfers heat to the treatment solution in the regenerator from the treatment solution discharged from the absorber and the gas to be treated from which the acidic compound has been separated.
