Polyether Demulsifier for Crude Oil
Polyether demulsifier is an EO/PO block copolymer-based chemical used for efficient oil-water separation in crude oil production and processing. It destabilizes water-in-oil and oil-in-water emulsions by displacing natural emulsifiers from the oil-water interface, achieving residual water content below 0.5% at low dosage (10–50 ppm). Suitable for both offshore and onshore production facilities and compatible with a wide range of crude oil types.
