Abstract
Process for separating the components of a gaseous mixture, saving energy and operating by demixing wherein the mixture to be separated is contacted under extracting conditions with a solvent which is then cooled down to a demixing temperature to provide two liquid phases, one of which has an increased extract content and the other an increased solvent content. The extract is recovered and the solvent recycled. The process can be used for numerous applications in the field of gas treatment.
