The separation of oil emulsions is an important step in the purification of crude oil from water, mineral salts, and various associated contaminants, asphaltene-resinous substances, and paraffin contained in the oil. In the formation and stabilization of oil emulsions in the form of colloidal particles in the oil, insoluble dispersed solids also have a high effect. Examples of such substances are microcrystals of solid paraffins, asphaltenes, ferrous sulfides, and other mechanical mixtures. These substances form a strong mechanical barrier on small water droplets distributed in the oil phase, which prevents the separation of water. In this work, the effect of various compounds in the oil on the separation of oil emulsions was studied in detail, a suitable model was proposed, and information was provided on promising methods for the separation of oil emulsions
