FIELD: chemistry.
SUBSTANCE: present invention relates to a liquid absorbent for CO2 and/or H2S, as well as device and method using it. Disclosed is a liquid absorbent that absorbs CO2 and/or H2S contained in gas. Absorbent contains the following components: (a) a secondary linear monoamine; (b1) a tertiary linear monoamine or (b2) a sterically hindered primary monoamine; and (c) secondary cyclic diamine, wherein concentration of each of said components is less than 30 wt%.
EFFECT: invention reduces the amount of heat supplied to the reboiler when performing the regeneration of the liquid absorbent.
