This study aimed to derive a new composite demulsifier for dehydration of highly emulgated oil with high paraffin content, reducing the emulsion stability. The main active substances are fatty acids of cotton steatite esterified with polyethylene glycol, as well as sulfanol, Sintanol ALM-10, silica gel, and white spirit in certain proportions. Studies under laboratory conditions on the demulsification of oil from Ashysay field showed that the new composite demulsifier is a suitable reagent for the destruction of water-oil emulsions. Sulfanol and Sintanol ALM-10 confer washing and wetting effects on the mixture, and silica gel favors the adsorption of oil asphaltenes onto its surface.
