A continuous process is disclosed for separating components of a hydrocarbon gas stream selected from the group consisting of hydrogen, nitrogen, methane, ethylene, ethane, higher saturated and unsaturated hydrocarbons, and mixtures thereof by countercurrently contacting the hydrocarbon gas stream with a physical solvent to produce an overhead stream which is rich in at least one of the components and a rich solvent bottoms stream which is rich in another of the components, and thereafter recovering the solvent bottoms stream and recycling it to the contacting step.
