Abstract: A process for recovery of hydrocarbon (C.sub.2.sup.+) containing at least two carbon atoms per molecule (e.g. LPG) from a fluid feed containing C.sub.2.sup.+ hydrocarbons and components having at most one carbon atom per molecule (e.g. refinery gas) comprising the following steps:(i) contacting the fluid feed with one side of at least one membrane which is substantially non-permeable for C.sub.2.sup.30 hydrocarbons and removing a first fluid (permeate) containing a substantial amount of components having at most one carbon atom per molecule from the other side of the membrane(s), and(ii) fractionating fluid (retentate) obtained from the one side of the membrane(s) into at least a product containing C.sub.2.sup.30 hydrocarbons and a gaseous product.
