Study of electrokinetic nature of emulsion bindes

Abstract

The electrokinetic nature of crude oil emulsions is evident to the fullest extent in connection with the demulsifying of oil emulsions during crude oil production. The techniques of reverse-type emulsions studies are developed. During the passage of direct or alternating current through the emulsion coalescence of water droplets observed solar cells may occur [6]. Through the microscope, it was seen that the emulsion droplets in an electric field are deformed and grouped into chains, which are located parallel to the power lines. In water-in-oil (W/O) emulsion coalescence occurs when droplets forming a chain come into contact. These chains are conductive and repel each other. In oil-in-water (O/W) emulsion such chains do not coalescence. When charging the capacitor containing emulsion energy is used not only on the polarization of the dielectric medium, but also on the mechanical work, namely droplet deformation and changes in the distribution of the dispersed phase in the volume [2]. The investigated mechanism of electrokinetic interaction is based on polarization dipole molecules of hydrocarbon binders (O/W) or water molecules (W/O). In this paper we consider fundamentally the same mechanism of formation and coalescence of emulsions, but in the presence of polar emulsifier, due to which we artificially set the necessary principle of interaction, thus providing the desired properties of the emulsion in advance. Experiments have revealed electrokinetic aspects of emulsion binders, a method of determining the parameters of the electric double layer of emulsions and the tie of these parameters with current ideas on the formation, existence in time and their decay. According to the results of comparative tests of electrokinetic properties of various emulsions a method of comparative analysis of emulsion binders prepared with different binders is proposed.
