Abstract
A method of recovering gaseous hydrocarbons from tank headspace includes flowing a hydrocarbon gas composition from headspace of a tank fed by a secondary separator into a compressor to form a compressed mixture. The method includes flowing the compressed mixture into a cooling unit to cool the compressed mixture, to form a cooled composition including liquid hydrocarbons. The method includes recovering the liquid hydrocarbons as a recovered liquid hydrocarbon stream.
