Title: Treatment of solid-stabilized emulsions

Abstract: An emulsion treating unit and process. A subcooled boiling zone in the unit comprises a heat transfer surface to contact an emulsion at a temperature in excess of the saturation temperature of an aqueous phase in the emulsion, wherein the boiling zone is atmospherically vented. The unit also provides means for recovering an oil-rich layer from adjacent a vapor-liquid interface; and means for recovering an aqueous-rich layer from below the oil-rich layer. The process provides operation of the treating unit to heat an emulsion in the subcooled boiling zone, wherein the boiling zone is atmospherically vented, recovering an oil-rich layer and recovering an aqueous-rich layer from below the oil-rich layer. In one embodiment the boiling zone comprises a heat transfer surface having a temperature in excess of the saturation temperature of the aqueous-rich layer, wherein the vapor-liquid interface is subcooled with respect to the saturation temperature of the aqueous layer.
