Abstract
A composite amine absorbent according to the present invention is an absorbent for absorbing COor HS, or both of COand HS 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 COor HS, or both of COand HS and good releasability of COor HS absorbed during regeneration of the absorbent. Furthermore, the amount of water vapor in a reboilerused during regeneration of the absorbent in a COrecovery unitcan be reduced.R—O—(R—O)—R  (I)
