Abstract
The composite amine absorbing solution according to the present invention absorbs COor HS or both in a gas, and is obtained by dissolving a linear monoamine, a diamine, and an amide group-containing compound in water. By adopting this composite amine absorbing solution, the composites are interacting in a composite manner, due to an integrated effect of the components, the absorption property of COor HS or both is favorable, the desorption properties of the COor HS absorbed when regenerating the absorbing solution become favorable, and the amount of steam from a reboiler used when regenerating the absorbing solution in a COrecovery device can be reduced.
