Abstract: A natural gas is deacidized by contacting the natural gas with solvent containing methanol, water and amine, for two times, and distilling the first fraction of partly regenerated solvent. A second fraction of partly regenerated solvent is mixed with fourth solvent drawn-off at point of distillation column. The draw-off point is determined for the proportion by mole of methanol of first solvent to be higher than that of the second solvent.  Deacidizing of a natural gas comprises contacting the natural gas with a first solvent containing methanol, water, and amine and with a third solvent containing acid gases so as to obtain a methanol-containing gas and acid gas-containing solvent. The obtained gas is contacted with a second solvent containing methanol, water and amine so as to obtain a gas partly freed of acid gases and the third solvent containing the acid gas. The acid gas-containing solvent is expanded to release acid gases and to obtain a partly regenerated solvent. A first fraction of the partly regenerated solvent is distilled to obtain a gas phase containing acid gases and the second solvent. A second fraction of partly regenerated solvent is mixed with a fourth solvent drawn off at a point of distillation column to obtain the first solvent. The draw-off point is determined for the proportion by mole of methanol of first solvent to be higher than that of the second solvent.
