摘要： An absorbent according to the present invention is an absorbent for absorbing CO 2 or H 2 S, or both of CO 2 and H 2 S in a gas. The absorbent contains, as components, (a) a secondary linear monoamine, (b) a tertiary linear monoamine, and (c) a secondary cyclic diamine. When the concentration of the secondary linear monoamine (a) is more than 30% by weight and less than 45% by weight and the concentration of the tertiary linear monoamine (b) is more than 15% by weight and less than 30% by weight, absorbability of CO 2 or H 2 S, or both of CO 2 and H 2 S is good, and releasability of CO 2 or H 2 S that have been absorbed during regeneration of the absorbent is good. The amount of steam of a reboiler 26 used during regeneration of the absorbent in a CO 2 recovery unit 12 can be thus reduced.
