Oil Demulsifier

Demulsifier is a chemical used to break emulsions that is, to separate the two phases. The type of demulsifier selected depends on the type of emulsion, either oil-in-water or water-in-oil. Demulsification is used for the separation of water from crude oil. As crude oil is produced from a reservoir it tends to become mixed with either natural formation water or mixed formation and injection water. It is critical for refining process operations that the crude oil is efficiently and quickly separated from the water to allow oil to be exported and clean water to be discharged within consent, thus maximizing crude oil value and minimizing operating costs.
