Abstract
The separation of water–oil emulsions differing in the content and ratio of asphalt-resinous substances, as well as dielectric properties when exposed to a high-frequency (HF) electromagnetic field is investigated. The results of experimental studies are presented, showing the correlation between the degree of phase separation from dielectric parameters and the ratio of asphaltenes and resins in oils. It is shown that when water–oil emulsions are exposed to an HF electromagnetic field, the degree of heating and the efficiency of phase separation of the emulsion depend on the total content of asphaltenes and resins, their ratio, and whether the operating frequency of the generator falls within the region of resonant frequencies of the emulsions.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
