Abstract: A method of recovery of rich gas where the rich gas is a hydrocarbon gas comprising less than 50 mole % methane is disclosed. The method comprises the steps of gathering the low pressure gas, compressing the gathered gas, cooling the compressed gas in a condenser so that a portion of the compressed gas condenses to form a liquefied gas and liquefied gas vapour in the condenser, and discharging the liquefied gas and liquefied gas vapour from the condenser, in which the cooling of the compressed gas is performed using at least one heat exchanger (40).

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.

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.

Abstract: 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.
