ABSTRACT:
Oil well production fluid is gravitationally segregated into different phase within a tank whose top has a regulated exhaust line to remove any gas phase. An outlet end of the tank has a water phase discharge line from a lower region and an emulsion phase discharge line from the upper region of the tank. Both discharge lines have normally closed dump valves that are operationally coupled to a pneumatic actuator and a probe that measures the electrical capacitance of the oil emulsion and water phases that are alternately present at an intermediate level of the tank. Oil emulsion overflows from the liquid packed tank into a downcomer that opens into the upper region of a water manifold to displace water out of the lower region of the manifold and into a water chamber on one side of a bladder of a pressure vessel. A gas charged chamber of the pressure vessel is operatively coupled to a high-low pressure switch that is electrically coupled to the probe. A high gas pressure effects closing of the high-low switch and consequent opening of one of the normally closed valves to dump the particular liquid phase detected by the probe at the intermediate level of the tank by the decompression of the gas chamber of the pressure vessel. Decompression of the gas chamber of the pressure vessel opens the high-low switch to effect closing of the previously opened valve.
