Abstract
Process for recovering a solvent from a gas coming from a treating process using the solvent, the gas having a low temperature Ta and a high temperature Td, the difference Td-Ta being sufficient to carry out an adsorption step and a desorption step. The process is characterized in that/ a) a first solvent-containing gas stream is sent to an adsorption step, this gas being at a temperature Ta, at the end of this step the gas is practically solvent-free and the solvent is collected in a first adsorber, b) a second gas stream at a temperature Td, this gas being solvent-free, is sent to carry out desorption of a second adsorption means loaded with solvent during a previous step a), and c) the solvent is sent at least partly to a step of the treating process using the solvent.
