Summary:In this work, we summarize experimental data on the influence of ultrasonic treatment alone and sonication with subsequent introduction of oil with high resin content, on the structural and rheological parameters of highly paraffinic oil. Our results clearly indicate that Ultrasonic treatment of oil stimulates the crystallization of paraffin. This leads to an increase in viscosity, pour point and the amount of paraffin deposited. The introduction of highly resinous oil into the sonicated highly paraffinic oil improves the viscosity-temperature characteristics, reduces the specific energy of degradation of the supramolecular structure, and positively affects the mass and the structure of sediments. Significant inhibition of the process of sedimentation and improvement of the viscosity-temperature properties is observed only when 10 wt.% of resinous oil is added to sonicated paraffinic oil. The results of our work indicate that mixing oils with various compositions in combination with ultrasonic treatment could be used for the transportation of highly paraffinic feedstocks through pipelines at low temperatures.
