In a process for the separation of unsaturated hydrocarbons from mixtures containing them, the feed is led through a microporous hollow fibre membrane, while an aqueous solution of a complexing agent flows at the other side of the membrane. The unsaturated hydrocarbon forms a reversible water-soluble complex. After separation of the complex, the latter is led along a second membrane under conditions which lead to the dissociation of the complex.

Selon un procédé permettant de récupérer des hydrocarbures insaturés à partir de mélanges les contenant, on fait passer la charge d'alimentation à travers une membrane microporeuse à fibres creuses, tout en faisant s'écouler de l'autre côté de la membrane une solution aqueuse d'un agent formateur de complexe. L'hydrocarbure insaturé forme un complexe hydrosoluble réversible. Après séparation du complexe, on le fait passer sur une seconde membrane dans des conditions aboutissant à sa dissociation.
