Abstract
The process of this invention is a hybrid gas separation process which recovers both heavy hydrocarbon and high purity hydrogen products from a gas stream containing a relatively low concentration of hydrogen. The heavy hydrocarbon product may consist of C.sub.2 +, C.sub.3 + and/or C.sub.4 + hydrocarbons. The light hydrocarbons and other light components, such as N.sub.2 and CO, are removed as a light fuel gas stream. After convertional removal of any components which might freeze at low temperatures, the feed gas is combined with recycle gas from the hydrogen purifier and fed to the cryogenic unit.
