Abstract
Ultrasonic treatment is a promising crude oil preparation method implemented using emitters of ultrasonic vibrations in the 1–100 kHz frequency range. The optimum conditions of applicability of this method and the impact parameters are determined and ultrasonic oil treatment technology is investigated for different volume water contents of the emulsion. It is shown that under the impact of acoustic vibrations the disperse phase droplets coalesce and the demulsification process occurs more actively than in traditional thermochemical dewatering process. The conditions of applicability of the method is analyzed and the technological advantage of breaking stable water-oil emulsions for field oil preparation in the Perm Krai (Perm Region) is assessed. Based on the experimental data, relationships describing the nature of the effect of ultrasonic impact parameters on stable water-oil emulsions breaking at different water contents and under phase inversion conditions are investigated.
