Destruction of water-in-oil emulsions in electromagnetic fields

Abstract

Abstract In this paper, we study the degree of exposure of electromagnetic fields to water-oil emulsions with different physical and chemical properties, as well as the characteristics of their heating and delamination when exposed to radio frequency and microwave frequencies in electromagnetic fields. Experimental research methods are described. The results of experimental studies of heating emulsions in radio frequency and microwave electromagnetic fields under dynamic conditions and the results of their separation are presented. As a result of the research, it has been found that when exposed to radio frequency or microwave electromagnetic fields on oil-water emulsions, the degree of heating and the efficiency of emulsion stratification depend on the total content of asphaltene and resins, the water content in the emulsion, and the operating frequency of the generator in the region of resonant frequencies for emulsions. For all types of emulsions, radio frequency action is more effective than a microwave field, with low water contents. With increasing water content the efficiency of microwave exposure increases. Also, with an increase in the water content, the intensity of heating the emulsion in the microwave field increases with the same energy inputs.
