Demulsifier

DEMULSIFIER also called Emulsion breakers are used to separate emulsions i.e water from oil.They are class of speciality and industrial chemicals.

They are commonly used in the processing of crude oil, which is typically produced along with significant quantities of saline water. This water (and salt) must be removed from the crude oil prior to refining. If the majority of the water and salt are not removed, significant corrosion problems can occur in the refining process.
