1. A method of recycling gaseous hydrocarbons, the method comprising:

flowing a hydrocarbon gas composition from a first separator into a compressor to form a compressed mixture, wherein the first separator comprises a crude hydrocarbon input stream, and wherein the compressor comprises an oil-less compressor that comprises a crankcase that is free of oil that contacts material being compressed and is free of oil lubrication that requires regular changings; and

flowing the compressed mixture into a cooling unit to cool the compressed mixture, to form a cooled composition comprising liquid hydrocarbons.
