Definitions

  • Entrance bushings constructed with proper plastic insulating material can withstand very high operating pressure in the range of severalthousand psi where the temperatures are relatively low, for example, ambient temperature of 6080F. Alternatively, these bushings can withstand relatively high temperatures of up to about 500F. where the operating pressure is relatively low, for example, 15 psi differential across the plastic insulating material. In either case, the plastic insulating material can be used within an entrance bushing and safely isolate electrical potentials up to 50 kilovolts (ac-dc) for extended periods of time and in complete safety.
  • the upper portion of the tubular member of the plastic is carried in a metal adapter which is mounted in the sidewall of the vessel.
  • the insulating material has a thermal expansion coefficient several times that of the metal (steel) components of the entrance bushing. Also, this insulating material in the cycling of operating temperatures, retains the structure induced at the maximum temperature. A substantial temperature gradient established along the tubular member and across metal parts which form fluid seals creates severe longitudinal stresses to produce seal failure. Emulsion leakage into the entrance bushing results with entry into the metal conduit which contains the electrical conductor connecting to the external power source. An electrical arc may then occur which can destroy the electrical conductor, the entrance bushing, or both.
  • FIG. 7 is a longitudinal section of another embodiment of the feed-through insulator with a fluidactuated seal for use in the system shown in FIG. 6;
  • the pressure conduit 17 is connected in fluid-tightness to the metal adapter 21.
  • a coupling 49 received within a groove 51 in the metal adapter 2 1 is secured integrally to the metal adapter 21 by an induction weld 52.
  • the coupling 49 removes heat energy from the metal adapter 21, the heat sink therein conducts replacement heat energy from the sidewall of the vessel 12.
  • the tubular member 23 is maintained at substantially the same temperature during operation of the vessel as the emulsion contained therein irrespective of losses through the coupling 49.
  • the metal adapter 21 in the entrance bushing 18 may be employed to provide a heat conductive element integrally interposed-between the tubular member 23 and the pressure conduit 17.
  • the opening in the metal adapter 21 accommodating the cable 27 is the sole aperture through the heat conductive element. This arrangement insures that the tubular member 23 will be maintained at substantially the same temperature throughout its length, and at the temperature of the emulsion within the vessel l2.
  • Finned tubing is satisfactory for the most purposes since the amount of heat energy transferred relative to the pressure conduit 17 and power source terminals of the insulators is relatively of small magnitude. circulating ambient temperature air is sufficient to transfer the required heat energy for most applications of the present invention. In some high temperature environments, it might be'desired to provide the heat exchanger with a liquid cooling.
  • the chamber 152 has vent plugs 161 and 162 so that both sides of the piston 156 in chamber may be vented and completely filled with dielectric liquid.
  • the chamber 152 behind the piston 156 also connects with a reservoir 164 to allow dielectric liquid to flow into and out of chamber 152 from behind piston 156.
  • the reservoir 164 may be of a pneumatic balance accumulator design.
  • the outlet chamber 158 also has a vent plug 163 to insure that dielectric liquid completely fills the chamber 158 and the conduit 136 in communication with the feed-through insulator 131.
  • a system for electrically treating an oil continuous emulsion containing dispersed phase contaminating substances comprising:
  • electrode means for creating an electric field for promoting emulsion resolution within said vessel
  • system means for maintaining the dielectric liquid within said highpressure conduit at substantially the same pressure as the emulsion within said vessel, and said system including a dynamic fluid barrier for preventing intermingling of the emulsion and dielectric liquid;
