Abstract
A method of recycling gaseous hydrocarbons includes flowing a hydrocarbon gas composition from a secondary separator into a compressor unit to form a compressed mixture. The secondary separator includes a crude liquid hydrocarbon input stream from a primary separator. The method includes flowing the compressed mixture into a cooling unit to cool the compressed mixture, to form a cooled composition comprising liquid hydrocarbons. The method includes flowing the liquid hydrocarbons from the cooled composition into the primary separator.
