ABSTRACT:
An electrical field treater for resolving an emulsion formed of a continuous oil phase containing a dispersed water phase with grading a.c.-d.c. electric fields. The treater comprises a metal vessel having an emulsion inlet and outlets to remove the purified oil phase and a coalesced water phase. Insulated electrode sets are energized by an external power source to regulated d.c. potentials between the electrodes and earth ground, and an a.c. current component between the electrodes and earth ground. The earth ground may be a metal electrode or a body of water maintained in the vessel.
