ACIDIC GAS ABSORBENT, REMOVAL METHOD OF ACIDIC GAS AND REMOVAL DEVICE OF ACIDIC GAS

摘要

PROBLEM TO BE SOLVED: To provide an acidic gas absorbent where the absorption amount and absorption rate of an acidic gas (especially, CO) per unit volume are large and the dissipation of an absorbent component is prevented and to provide a removal method and a device of the acidic gas where needed energy at the separation of the acidic gas and the reproduction of an absorbent is reduced.SOLUTION: An acidic gas absorbent containing two kinds of amino acid salts having a cyclic structure inside and a tertiary amine compound and a removal method and a device of the acidic gas using the absorbent are provided.SELECTED DRAWING: None
