FIELD: oil industry.
SUBSTANCE: invention relates to methods of oil preparation for dehydration of oil emulsions and can be used in oil production and oil refining industry. Method of separating water-oil emulsions includes supplying water-oil emulsion between the anode and cathode units, treatment of the emulsion with an electric field in the area of the anode and cathode units, wherein treatment of water-oil emulsion is carried out with drifting electrons of thermionic emission in power electric field with intensity 4⋅105–6⋅105 V/m.
EFFECT: intensification of emulsion separation by reduction of its duration and reduction of residual water content.
