Abstract

See full text

An absorber that uses a gasified gas containing CO2 and H2S formed by gasifying coal, for example, as an introduced gas, and that makes the CO2 and H2S absorbed from the introduced gas by bringing the introduced gas into contact with an absorbent for absorbing C02 and H2S; an absorbent regenerator-that extracts absorbent that has absorbed CO2 and H2S from the bottom of the absorber and introduces the absorbent from the top of the absorber, and that regenerates the absorbent by releasing the CO2 and H2S; a second supply line that returns the regenerated absorbent from the regenerator to the absorber; and a third supply line that extracts the absorbent (semi-rich solution) that has absorbed a part of the CO2 and H2S from the vicinity of the middle of the absorber, and that introduces the semi-rich solution in the vicinity of the middle of the regenerator.
