Abstract: A separator for oil-continuous dispersions containing a dispersed water phase. A horizontal vessel contains a horizontal non-pressure baffle forming an outlet zone superimposed above an electric field treatment zone. Openings along one side of the baffle provide fluid communication between these zones. An open-bottom inlet zone, extending longitudinally along the other side of the vessel, is formed by a vertical non-pressure baffle extending downwardlly from the horizontal baffle to adjacent the bottom of the vessel. A water separation zone extends upwardly to a horizon intermediate the open bottom of the inlet zone and the horizontal baffle to define the electrical field treatment zone. Passageways in the vertical baffle deliver dispersion from the inlet zone into the electric field treatment zone with volumes of bulk water phase being discharged downwardlly through the open bottom of the inlet zone into the water separation zone. Electric field resolution produces a dry oil phase passing into the outlet zone for removal from the vessel. Accumulating water phase is removed through an outlet from the water separation zone.
