n: a housing built around controls on equipment that is sensitive to cold. such as heater-treaters.

n: a vessel holding sodium hydroxide or other alkalis through which a solution flows for removal of sulphides, mercaptans, or acids.

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: a vacuous ejector composed by vaccum pump ,vaccum pot and rotor pump

n: the valve through which oil and water are discharged from separators. treaters. and so on. It is usually a motor valve. but may be a liquid-level controller as well. dunefield n: an accumulation of windbome sand on that part of the seashore that lies above storm-flood level.

n: the window slide valve installed on the top of the screwdrill
which closes when trun on the pump and open when stop the pump

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 fibrous material used as a filtering element in heaters or heatertreaters.
