OIL DESALTING AND DEWATERING

The invention includes a method for dewatering and/or desalting a water-in-oil emulsion comprising introducing a plurality of streams of the emulsion into the electrostatic field under opposed flow whereby the water coalescence is enhanced. The invention also includes an improved electrostatic appar...
