    摘要： An apparatus and method for separating water from an oil-water influx are provided. The apparatus includes a separation vessel having an inlet, an oil collection portion at its upper end, and a water collection portion at its lower end. Multiple high voltage tubes, each containing an electrode, are located within the oil collection portion. These high voltage tubes are staggered in length and held in place by perforated plates. The oil-water influx flows through the inlet of the vessel into the high voltage tubes, where it is subjected to an electrostatic field. The electrostatic field causes water droplets in the influx to coalesce and form a water out-flux which flows downwardly into the water collection portion of the vessel. The remaining stream of dehydrated oil flows upwardly to the upper outlet end. The oil collection portion of the separation vessel may be oriented vertically or at an angle.

    摘要： Low-water content organic phases can be difficult to achieve at high fluxes when water is present in an emulsified form, such as in a water-in-oil emulsion. Processes for de-emulsifying a fluid stream containing emulsified water, such as water-in-crude oil emulsions, include introduction of the fluid stream into a vessel that defines a coalescence zone. The vessel is configured to provide for simultaneous application of a centrifugal force and an electric field to the fluid stream within the coalescence zone. The simultaneous application of the centrifugal force and the electric field to the fluid stream provides for the coalescence of a portion of the emulsified water into a bulk aqueous phase. Continuous phases of the organic component and the bulk aqueous phase form in the coalescence zone and are separately removed from the vessel. The bulk aqueous phase is removed from the underside of the vessel.
