Introduction of Demulsifier
Demulsifier is mainly a non-ionic surfactant, which is formed by polymerization of the starting agent with epoxy propane and ethylene oxide block, or by modifying or compounding the polymer.Demulsifier is mainly used for demulsification and dehydration of crude oil in oil field, and also for desalination and dehydration in refinery.According to solubility, it can be divided into water solubility and oil solubility.According to the initiator, it can be divided into alcohol, amine, phenolic resin, phenolic amine resin, compound initiator and so on.According to its application, it can be divided into conventional demulsifier, ternary compound flooding fluid demulsifier, heavy oil demulsifier, condensate demulsifier, high wax demulsifier, water demulsifier, low temperature demulsifier, high flash point demulsifier, etc.
Demulsifier is widely used in Petrochina, Sinopec, Cnooc, Sinochem, Yanchang petroleum and other domestic&International oil fields and refinery companies.
Water-soluble demulsifier
It includes dry agent and finished product, which can be used only when methanol and water are used as solvent to prepare the finished product, which is soluble in water and alcohol.Water-soluble demulsifier is the most important demulsifier in domestic market.Can choose different breed and usage amount according to oil quality.

The Application of Demulsifier
This product is water-soluble surfactant, with a strong surface activity, good wetting properties and sufficient flocculation and coalescence ability to adsorb to all types of crude oil emulsion oil water. membrane interface, significantly improve the interface properties, significantly reduce the interfacial film strength and effectively implement emulsion breaking, dehydration.
Safety and instructions for use
When using this product, the staff should wear appropriate labor insurance articles, avoid splash in the entrance, eyes, splash should be promptly washed with water, workplace prohibit fireworks.Dry agents are non-hazardous chemicals.
The finished product can be directly added to crude oil for use, or diluted with water for use.It is strictly forbidden to mix with oil-soluble demulsifier.
