UNSATURATED HYDROCARBON SEPARATION AND RECOVERY PROCESS

摘要

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 th e complex, the latter is led along a second membrane under conditions which lead to the dissociation of the complex.
