ABSTRACT:
A heating chamber is provided for receiving well effluent therein including oil, water and gas and a heated chamber is also provided for containing glycol to be heated. Heat exchange coils are disposed in the chambers and are serially connected in a loop flow path with gas pressure operated pump structure operatively associated with the flow path for pumping glycol therethrough. Gas-fired heating structure is operatively associated with the heated chamber for heating glycol therein and a gas outlet from the heating chamber comprises a source of well gas under pressure through supply structure supplying well gas to the pump and burner structures. The supply structure includes a glycol-gas contactor for drying the gas provided from the supply structure to the pump. Glycol is supplied from the heated chamber to the glycol-gas contactor and the wet glycol discharged from the contactor is returned to the heated chamber through a heat exchange structure disposed within a storage tank communicated with the heated chamber for receiving glycol therefrom as glycol is drawn from the storage tank, and therefore the gas used to effect the glycol circulation in the two circulation loops is captured, stored and used as burner fuel and to operate other controls.
