ABSTRACT:
An electric treater for separation of a water-in-oil emulsion, which utilizes both AC potential applied to electrodes as well as DC potentials. A plurality of trays are provided through which the emulsion passes in series. One or more of these trays is supplied with AC potential to a series of insulated electrodes. Another tray is provided with a DC potential obtained from one half of a secondary winding of a transformer, through a rectifier, and at least a third tray is provided with a second DC potential derived from the opposite end of the secondary winding through a separate rectifier. The oil to be treated first passes through the tray or trays which have the AC potential, and then passes successively through the two trays which have the pulsed DC potential.
