Abstract

See full text

A method of recovering gaseous hydrocarbons from tank headspace as fuel on-site 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 flowing the cooled composition to a buffer tank to form a buffered fuel composition. The method includes removing a fuel gas composition from headspace of the buffer tank. The method also includes combusting the fuel gas composition as an on-site fuel.
