It is possible to use a coalescing media to promote coalescence of the water droplets. These media provide large surface area upon which water droplets…

The droplet diameter is the most important single parameter to control to aid in water settling since this term is squared in the settling equation.…
Adding heat to the incoming oil/water stream is the traditional method of separating the phases. The addition of heat reduces the viscosity of the oil…
Laboratory testing of a particular oil at various temperatures is the most reliable method of determining how an oil behaves. ASTM D 341 outlines a…
The process of coalescence in oil treating systems is time dependent. In dispersions of two immiscible liquids, immediate coalescence seldom occurs when two droplets collide.…
Most oil-treating equipment relies on gravity to separate water droplets from the oil continuous phase, because water droplets are heavier than the volume of oil…
Chemical demulsifiers sold under various trade names, such as Tretolite ™, Visco™, and Breaxit™, are highly useful in resolving emulsions. Demulsifiers act to neutralize the…
When thinking about emulsion stability, it may be helpful to realize that in a pure oil and pure water mixture, without an emulsifying agent, no…
For an emulsion to exist there must be two mutually immiscible liquids, an emulsifying agent, and sufficient agitation to disperse the discontinuous phase into the…
Removing water from crude oil often requires additional processing beyond gravitational separation. In selecting a treating system, several factors should be considered to determine the…
