Abstract
A process and apparatus for separating a hydrocarbon gas into fractions containing predominant portions of hydrogen, methane, and C.sub.2 and heavier components, where the methane and lighter components are separated from the feed gas under non-cryogenic conditions to produce a hydrogen-rich fraction, a first fraction rich in C.sub.2 and heavier components and a hydrocarbon-rich fraction, the hydrocarbon-rich fraction then being separated under cryogenic conditions into a second fraction rich in C.sub.2 and heavier components and a methane-rich fraction.
