The problem of water-in-oil emulsion destruction is related to many technological processes in the oil-and-gas industry, especially in extracting and processing of oil, preparation and transportation of oil, and liquidation/recycling of oil-sludge barns. High stability of water- -in-oil emulsions is conditioned by the oil high-molecular polar components which cover water droplets and form armor envelope, and that prevents coalescence of the droplets. The usage of conventional techniques to destroy the emulsions yields gives no positive results. The employment of electromagnetic (EM) field energy is one of the ways to solve this problem. To study the EM action on the water droplet surrounded by a dielectric liquid the system of heat and mass transfer equations within the droplet and in the surrounding liquid is considered. A mathematical model of temperature distribution within a single droplet and surrounding liquid under the action of microwave electromagnetic radiation is formulated. The problem is solved numerically taking into account the thermal motion of the fluid within the water droplet and in the surrounding liquid. It is shown that the radiation induced heating of the droplet and the surrounding liquid is non-uniform. The results can help to understand the physical mechanisms of water-in-oil emulsion destruction in EM field.
