    摘要： A regenerative process for deacidification of a gas containing CO2 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 CO2 by the amine, thereby producing a treated gas with reduced CO2 content and an absorbent liquid loaded with CO2, subjecting the loaded absorbent liquid to a regeneration treatment to release CO2 which it has bound, to produce 1) at least one acid gas fraction rich in CO2 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 CO2 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 CO2 and liquid hydrocarbons consists of at least one compound of formula H2N—CnH2n—NH—CH2—CH2OH in which n represents an integer ranging from 1 to 4.
