Composite Amine Absorption Solution, Removal Device, And Removal Method
Abstract: The present invention addresses the problem of being able to efficiently release captured CO2 and H2S at a fast reaction speed. A composite amine absorption solution according to the present invention absorbs at least either the CO2 or H2S in a gas, the solution including: (a) a chain monoamine; (b) a diamine; (c) a cyclic compound having the chemical formula, where R1 is any one of hydrogen, a hydrocarbon group having a carbon number of 1 to 4, or a hydroxyalkyl group, R2 is oxygen or N-R3, and R3 is any one of hydrogen, a hydrocarbon group having a carbon number of 1 to 4, or a hydroxyalkyl group; and (d) water.
