Abstract: A composite amine absorbent according to the present invention is an absorbent for absorbing CO2 or H2S, or both of CO2 and H2S in a gas. The absorbent is obtained by dissolving (1) a linear monoamine, (2) a diamine, and (3) propylene glycol alkyl ether, for example, represented by the following chemical formula (I) in water. In the composite amine absorbent, the components complexly interact, and the synergistic effect thereof provides good absorbability of CO2 or H2S, or both of CO2 and H2S and good releasability of CO2 or H2S absorbed during regeneration of the absorbent. Furthermore, the amount of water vapor in a reboiler 26 used during regeneration of the absorbent in a CO2 recovery unit 12 can be reduced.
