ABSORBENT SOLUTION BASED ON N,N,N',N'-TETRAMETHYLHEXANE-1,6-DIAMINE AND ON ONE PARTICULAR AMINE COMPRISING PRIMARY OR SECONDARY AMINE FUNCTIONAL GROUPS AND PROCESS FOR REMOVING ACID COMPOUNDS FROM A GASEOUS EFFLUENT

摘要

The invention relates to the removal of acid compounds in a gaseous effluent in an absorption process that uses an aqueous solution of N,N,N',N'-tetramethylhexane-1,6-diamine formulated with one particular primary or secondary amine, that makes it possible to obtain a single-phase absorbent solution under the conditions of absorption of acid gases such as CO2. The invention advantageously applies for the treatment of natural gas and of gas of industrial origin.
