UNPChemicals high-performance crude oil demulsifiers are specially designed to break stable water-in-oil (W/O) and oil-in-water (O/W) emulsions in crude oil production. They deliver fast separation, lower treatment costs, and help you meet pipeline and refinery specifications.
Instock & Custom Demulsifiers
Crude Oil Demulsifiers are your optimal solution for heavy crude oil recovery. Revolutionize your operations with our demulsifiers, engineered to expedite the oil separation process, thereby accelerating production goals. Remain confident in meeting commercial crude oil specifications with our product's role in improving output quality.
UNPChemicals' demulsifier DEMET® series is mainly divided into three categories: "dryer type", "droppers type" and "desalter type", based on the dehydration speed and the water content of the crude oil after dehydration.

Demulsifiers are specialized chemical additives designed to separate emulsified water from crude oil. They break down stable water-in-oil (W/O) emulsions formed during crude oil extraction, gathering, and processing, quickly clarifying the oil-water interface, removing moisture, salts, and solid impurities.
By improving dehydration efficiency, they help crude oil meet pipeline and refinery specifications, protect equipment from corrosion, reduce energy consumption, and ensure smooth production and transportation.
High-performance solutions for exploration, upstream, and refinery applications.
A liquid oxyalkylate category, utilized in the industrial market for crude oil desalting processes, particularly in exploration and upstream applications.
