Title:
複合アミン吸収液、ＣＯ２又はＨ２Ｓ又はその双方の除去装置及び方法
Document Type and Number:
Japanese Patent JP6841676
Kind Code:
B2
Abstract:
The composite amine absorbing solution according to the present invention absorbs CO 2 or H 2 S or both in a gas, and is obtained by dissolving (1) a linear monoamine, (2) a diamine, and (3) 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 CO 2 or H 2 S or both is favorable, the desorption properties of the CO 2 or H 2 S absorbed when regenerating the absorbing solution become favorable, and the amount of steam from a reboiler 26 used when regenerating the absorbing solution in a CO 2 recovery device 12 can be reduced.
