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 settling tank used to separate oil and water in the field. After emulsified oil is heated and treated with chemicals, it is pumped into the gun barrel, where the water settles out and is drawn off, and the clean oil flows out to storage. Gun barrels have largely been replaced by unified heater-treater equipment, rot are still found, especially in older or marginal fields. Also called a wash tank.

a vertical separator vessel.

n: a tank containing heated water through which crude-oil emulsion is forced to flow to remove water from the crude. Also called a gun barrel.
