OIL DEHYDRATION AND DEMINERALISATION METHOD Russian patent published in 2011 - IPC C10G32/02 

FIELD: oil and gas industry.

SUBSTANCE: invert emulsion is supplied to the device at values of temperature of the value at which oil congelation occurs; at that, for enlargement and merging of drops of water-oil emulsion there used is magnetic flux changing in time, which is induced by supply of alternating voltage of 110 to 3000 V for water-oil emulsion with alternating electric current in inductor winding through housing of the device, which is made from dielectric material.

EFFECT: reducing overall dimensions of devices for electric dehydration and demineralisation; improving efficiency of oil dehydration and demineralisation process; performing the heating process of oil emulsions, their dehydration and demineralisation with induction method; performing the demulsification process at low voltage, which improves electrical safety, allows avoiding the use of additional transformers, excluding the possibility of short circuits caused by increased oil water content.
