Emulsion typically takes place when normally immiscible oil and water are tied up together and are unable to separate without mechanical means or the aid of a chemical demulsifying agent. Typical emulsions are either, oil-in-water emulsion, where the oil droplets are trapped in the water phase, and water-in-oil emulsion, where the water droplets are trapped within the oil phase. How tight or loose an emulsion is depends on a number of factors including: properties of the oil and water, the amount of agitation or shear it undergoes, and the percentages of oil, water and emulsifiers present.
Cochran Chemical Company has numerous combinations of emulsion breakers designed to treat virtually every type of crude in the oil patch. When an emulsion problem is enhanced or coupled with the presence of paraffin and asphaltenes, we have products designed to effectively aid controlling paraffin/ashpaltene precipitation while resolving emulsion.
