PROCESS AND DEVICE FOR THE SEPARATION OF AN UNSATURATED HYDROCARBON FROM A FLUID MIXTURE WITH OTHER HYDROCARBONS

A fluid mixture from which an unsaturated hydrocarbon has to be separated, is passed in the first stage at superatmospheric pressure to one side of a first semiselective gas separation membrane with a non-porous active layer, and a liquid complexing agent is passed along the other side of said first...

Beschreibung
Zusammenfassung:	A fluid mixture from which an unsaturated hydrocarbon has to be separated, is passed in the first stage at superatmospheric pressure to one side of a first semiselective gas separation membrane with a non-porous active layer, and a liquid complexing agent is passed along the other side of said first membrane, where said unsaturated hydrocarbon is bound through complexation in the interface of membrane and complexing agent. In the second stage said unsaturated hydrocarbon is dissociated from the complexing agent through temperature increase, the mixture of complexing agent and dissociated unsaturated preferably is passed at superatmospheric pressure to one side of a second semiselective membrane with a non-porous active layer and the unsaturated hydrocarbon migrates to the other side of the membrane and is discharged. Finally, the complexing agent is recycled.
