【 摘 要 】

This paper summarizes the experimental work done on the effect of petroleum resins on the process of relaxation the structural and rheological properties of petroleum paraffin solutions treated in ultrasonic field. A combined treatment of petroleum paraffin solutions including 22 kHz ultrasonic exposure and addition of petroleum resins (0.3% 0.6% 0.9% by weight) was carried out. The addition of petroleum resins into the treated solution depresses the crystallization of hydrocarbons and favours the reduction of structural-mechanical characteristics of the system. The transition of the excited state of systems after the removal of the ultrasonic load to an equilibrium state occurs in time, and the nature of the change in the rheological characteristics and microstructure of paraffin crystals depends on the composition of the dispersion medium. It was revealed that trace amounts of resins introduced into paraffin oil systems treated with ultrasound will reduce their viscosity and improve transportation of hydrocarbons for 2 days at minimal cost.
