Abstract
Abstract An electric treater for oil field emulsions is disclosed with the power system for its electrode system a dominant feature in containing a fluid portion between the electrodes of variable conductivity. The variability of conduction is disclosed as either detected and manifested as a guide to operation or utilized to control the oil-water interface within the treater without drawing an overload of power.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
A system is adapted to supplying power to an electric treater of oil field emulsions, including, a pair of electrical power source terminals, a circuit connected to the terminals and adapted to include a portion comprising the fluid oil-water mixture of an emulsion, means connected to the circuit to manifest the power applied to the circuit, means maintaining a predetermined length for the circuit portion between the terminals, and means varying the electrical conductivity of the portion of the circuit, comprising a control system for regulating chemical injected into the emulsion, which chemical affects the electrical conductivity of the emulsion of the circuit portion.
