Abstract
A method of treating a fluid containing at least methane and at least one acid gas and producing the acid gas or gases in liquid form. The method includes a step of regenerating the solvent, operated at a pressure whose value is at least equal to the bubble pressure of the mixture of acid gases produced in liquid form, a step in which the gaseous fraction from the regeneration step is rectified in a contact zone by separating at least some of the solvent from the gaseous fraction, a step in which the gaseous fraction from the modification step is cooled to a given temperature to cause at least some of the gaseous faction to condense forming at least one liquid fraction enriched with liquid acid gases and a step during which the liquid fraction of gases is separated from the remaining gaseous fraction.
