Abstract
An absorbent liquid according to the present invention is an absorbent liquid for absorbing COor HS or both from gas, in which the absorbent liquid includes an alkanolamine as a first compound component, and a second component including a nitrogen-containing compound having in a molecule thereof two members or more selected from a primary nitrogen, a secondary nitrogen, and a tertiary nitrogen or a nitrogen-containing compound having in a molecule thereof all of primary, secondary, and tertiary nitrogens. The absorbent liquid has an excellent absorption capacity performance and an excellent absorption reaction heat performance, as compared to an aqueous solution containing solely an alkanolamine and a nitrogen-containing compound in the same concentration in terms of wt %, and can recover COor HS or both from gas with smaller energy.
