Abstract
There is disclosed a novel process and apparatus for liquefying a hydrocarbon gas under a pressure greater than the critical pressure thereof wherein the gas is first expanded to below the critical pressure thereof to permit the facile separation of C.sub.5 and heavier hydrocarbons with the lighter components being re-pressurized to above the critical pressure thereof by such expanding gas prior to the further cooling of such re-compressed lighter components for eventual liquefaction.
