Process and apparatus for separation of hydrogen, methane, and higher hydrocarbons from gas feed stock. For example, such feedstock is fed to a gas-liquid separator, the resulting gas is treated in a gas-gas membrane separator, the residue is separated in a second gas-liquid separator, and the permeate is separated in a second gas-gas membrane separator; the process may be repeated until the desired effluent specificity is achieved.

Method of separating components of a feedstock into one or more gas streams comprising mostly hydrogen or methane, and one or more liquid streams comprising mostly C-3 and higher hydrocarbons, comprising: (a) subjecting the said feedstock to one or more gas-liquid separations producing a gas effluent and a liquid effluent wherein the gas effluent is a feed to a next separation; (b) subjecting the gas effluent from (a) to one or more gas-gas membrane separations producing a gas residue from the membrane wherein the gas residue from the membrane is cooled producing a gas and liquid mixture and is a feed to a succeeding gas-liquid separation producing a gas effluent and a liquid effluent; (c) combining a major amount of liquid effluents from the above (a) and (b); and (d) subjecting the effluents combined in Step (c) to a stripping operation to provide a final liquid product.
