n: a brand name for an electrostatic treater.

v: to remove dissolved salt from crude oil. Sometimes fresh water is injected into the crude stream to dissolve salt for removal by electrostatic treaters.

n: see electrostatic treater.

n: a vessel that receives an emulsion and resolves the emulsion to oil, water, and usually gas, by using heat, chemicals, and a high-voltage electric field. This field, produced by grids placed perpendicular to the flow of fluids in the treater, aids in breaking the emulsion. Also called an electrochemical treater. See emulsion treating.

a separation device that uses alternating current charged plates to help break emulsions.

n: a system, chemical, device, or process used for breaking down an emulsion and producing two or more easily separated compounds (such as water and oil). Emulsion breakers may be (1) devices to heat the emulsion, thus achieving separation by lowering the viscosity of the emulsion and allowing the water to settle out;(2) chemical compounds, which destroy or weaken the film around each globule of water, thus uniting all the drops;(3) mechani- cal devices, such as settling tanks and wash tanks;or (4) electrostatic treaters, which use an electric field to cause coalescence of the water globules.

n: a cylindrical vessel into which an emulsion is piped to be broken down into its components. See electrostatic treater;heater-treater.
