Abstract

This work addresses one of the pressing issues in oil production — the formation of water-oil emulsions. Currently, there are various methods of dealing with them. The most common is the chemical method, which consists in the use of demulsifiers. The effectiveness of this method depends on the selection of the most optimal and cost-effective reagent. In the course of laboratory studies of various types of demulsifiers, it was found that a water-soluble demulsifier is more effective at destroying highly hydrated emulsions. The results are confirmed by experimental data and statistical calculations.

Key words:

water-oil emulsion, oil, demulsifier, surfactants, demulsification, intermediate layer, technological efficiency, protective shell, globules of water, stability of the emulsion
