Abstract

The influence of ultrasonic treatment, a polymer additive, and their combined effect on the structural and rheological properties of high paraffin, low-resin oil and the composition of separated sediments is studied. The oil was processed in the ultrasonic field (with the field intensity of 6 W/cm2, the frequency of 22 kHz, and the time of 1–10 min). The sedimentation process was carried out at an ambient temperature of 30°С and a coldfinger temperature of 5°С. A Brookfield DV-III ULTRA rotary viscometer was used to determine the viscosity-temperature parameters of the oil. Ultrasonic treatment for 1 min and a polymer additive (0.05 wt%) leads to a decrease in the viscosity by a factor of 5 and in pour point by 8°C. The introduction of the additive and the complex effect contribute to changes of the molecular weight distribution of n-alkanes in the sediments, viz. the second distribution maximum shifts to the region of higher molecular weight components and the concentration of n-alkanes ∑С17Н36–С33 Н68 increases.
