RESEARCH OF WATER-OIL EMULSION AT THREE REGIME ROTATIONS OF ROTARY-CAVITATION DISPERSANT WITH THE APPLICATION OF A HEAT EXCHANGER
Abstract
This article presents the main results of the study of the process of obtaining a stable, highly dispersed, water-oil emulsion at various revolutions of the rotary cavitation-dispersant. The dispersion characteristics of the resulting emulsion at different loading cycles in the dispersant and different surfactants are presented. It is shown that with an increase in the number of loads, the temperature of the resulting emulsion increases and its stability decreases. Therefore, the main studies were carried out with the connection of a heat exchanger, the cooling of the emulsion in which between cycles significantly increased the stability of the resulting emulsion. In conclusion, the stability kinetics and the granulometric composition of oil droplets are considered. It is shown that the greatest influence on the reduction in the size of oil droplets and the stability of the emulsion is exerted by an increase in the number of rotations of the rotor from 3000 to 6000 rpm, and then the number of loading cycles. An empirical equation for the description of the kinetics of emulsifiers in the oil-in-water system is proposed.
