Effect of impact of acoustic conditions on the breakdown of a stable oil-water emulsion is studied. The emulsion contains 80, 10 and 10 wt% of a solution of petroleum paraffin in 6 wt% of kerosene, distilled water, and highly resinous oil, respectively. Samples are treated in an ultrasonic field for 1-15 min at a frequency of 22 kHz, intensities 2, 6, 18 W/cm 2 , and temperatures 0 and 20 °C. It is shown that under optimal conditions of treatment (temperature 20 °C, 10 min, field intensity 18 W/cm 2 ) ultrasound causes the breakdown of the model emulsion. After demulsification, water, paraffins, and asphaltenes are concentrated in the lower layer. Ultrasonic treatment can be successfully used to treat watercut oils for transport.
