Abstract

The goal of this work is to study the influence of low-frequency acoustic field and polymer additive on structural and mechanical properties of problematic quick-freezing oil. The results were acquired by methods of rotational viscosimetry and finding phase transition temperatures by using optical density of infrared light as well as optical microscopy method. Highly paraffinic low-resin oil (Tomsk region) was exposed to low-frequency acoustic field (f = 50 Hz, 1 and 3 min of processing at 0 °С), a chemical reagent, the complexaction polymer additive D-210 (0.05% mass concentration in oil) and complex physical-chemical processing This work studies external influence on viscosity, temperature and energy characteristics, phase transition temperature as well as structure of oil residue. It was shown that in the case of problematic oil at a temperature close to freezing point, the acoustic influence leads to increase of viscosity and temperature properties. After adding the additive to processed oil during the complex processing, the thixotropic structure is destroyed, which is followed by a sharp decrease in viscosity, cloud point and freezing point. There is also a decrease in energy parameters, such as activation energy of viscous flow and internal energy of a disperse system. To determine the temperature of spontaneous crystallization we plotted the differential curves of viscosity coefficient dependence on the temperature of the medium. Study of the microstructure of the oil residue had shown that it contains small linear single-crystal and spherical formations prior to acoustic processing. After processing, however, such formations display a significant growth. The structure of the residue after complex processing is represented by many large plate paraffin crystallites.
