Demulsifiers introduction
Characteristics
Demulsifier is mainly non ionic surfactant, which is polymerized by starting agent and blocks of epoxy propane and ethylene oxide, or modified or built up for its polymers. Under normal temperature, it is one kind of pale yellow fluid which is classified into water-soluble demulsifier and oil-soluble demulsifier. The water-soluble demulsifier is dissolved in water or ethanol, and could be mixed with water in any ratio, forming into emulsion when meeting with water. The oil-soluble demulsifier is dissolved in organic solvents such as ethanol, benzene, methylbenzene, etc.

Purposes
Demulsifiers are mainly used for emulsion breaking and dehydration of crude oil in oilfields, also with the function of viscosity reduction. Petroleum refinery may apply it for desalting and dehydration. Oil field and refinery may choose appropriate demulsifiers for different oil products. The end products could be used directly. Water-soluble demulsifiers could also be used after being attenuated with water.
Package, Storage and Transportation
Pack in 200L clean dry metal drum. Storage and transportation shall be kept away from fire source and placed at ventilated and cooling place, prevent from water entering. Handle lightly in loading and unloading so as to avoid package from being damaged. The guarantee period of the product is one year. If exceeding, it shall be used after being qualified in inspection.
