en.Wedoany.com Reported - Gubkin Russian State University of Oil and Gas has developed an ultrasonic oil upgrading technology for oil fields. This method utilizes a cavitation field to alter the physicochemical properties of the raw material and reduce impurities.

The researchers have developed mobile devices based on controlled ultrasonic fields, which can be used at any site, including Arctic and continental shelf projects. During operation, sound oscillations form microbubbles in the liquid; when these microbubbles collapse, local pressure can reach tens of thousands of atmospheres, and the high temperature breaks bonds within hydrocarbon, resin, and asphaltene molecules.

Currently, transporting high-viscosity oil requires heating it to between 60 and 80 degrees Celsius, which significantly increases costs. Additionally, reducing sulfur content away from the oil field is a costly endeavor. Alexey Dengaev, head of the Laboratory for Physicochemical Research of Hydrocarbon Systems at Gubkin University, noted that the new technology can reduce raw material processing costs by dozens of times.
