Absorbent tertiary monoalkanolamine solution belonging to the 3-alcoxypropylamine family, and method for removing acidic compounds contained in a gas effluent

摘要

The absorbent solution for removing acidic compounds contained in a gas effluent comprises water and at least one amine that is selected from among tertiary monoalkanolamines that contain an etheric function and belong to the 3-alcoxypropylamine family having general formula (A). The method for removing the acidic compounds contained in a gas effluent involves placing a gas effluent 1 into the column C1 together with the absorbent solution 4.

1. A process for the removal of the acid compounds present in a gaseous effluent, in which a stage of absorption of the acidic compounds is carried out by bringing the gaseous effluent into contact with an absorbent solution comprising:
water; at least one amine corresponding to the following general formula (A): in which: R1 is an alkyl radical including from 1 to 6 carbon atoms, R2, R3 and R4 are independently chosen from a hydrogen atom and an alkyl radical including from 1 to 6 carbon atoms, R5 is an alkyl radical including from 1 to 6 carbon atoms, R6 is an alkyl radical including from 1 to 6 carbon atoms.
