Abstract
A regenerative process for deacidification of a gas containing CO,and liquid hydrocarbons including contacting the gas to be treated, in an absorption zone, with an absorbent liquid including methyldiethanolamine (MDEA) and an accelerator of absorption of CO,by the amine, thereby producing a treated gas with reduced CO,content and an absorbent liquid loaded with CO,, subjecting the loaded absorbent liquid to a regeneration treatment to release CO,which it has bound, to produce 1) at least one acid gas fraction rich in CO,and 2) at least one regenerated absorbent liquid; and recycling into the absorption zone the at least one regenerated absorbent liquid, wherein the overall liquid hydrocarbon content in the gas to be deacidified containing CO,is greater than 14 liters of liquid hydrocarbons per million standard cubic meters of gas, and the activator combined with methyldiethanolamine in the absorbent liquid brought into contact with the gas containing CO,and liquid hydrocarbons consists of at least one compound of formula H,N—C,H,—NH—CH,—CH,OH in which n represents an integer ranging from 1 to 4.
