    A considerable part of exploited oil is emulsion, which according to the World's statistics constitutes 25-35% of extracted oil. The presence of emulsion decreases oil production from wells, resulting in the increase of cost of its separation and acceleration of corrosion of production utilities. A number of methods of oil emulsion separation exist; however majority of them are based on the surfactants (demulsifiers). A specific surfactant may be efficient only for a given emulsion. It cannot be used for other emulsion without prior studies and analyses as may result in stabilization or formation of hardly separable multiple emulsions. The demulsifier should be so selected as not to cause corrosion of utilities. It should also be non-toxic and easily removable from sewage water. These issues are discussed in the paper.
