摘要

Electromagnetic synergistic oil-water separation is a promising technology for deep dehydration with higher efficiency, shorter dehydration period and flexible control of field parameters. In this paper, non-conductive silicone oil without colloid and asphaltene was used as the continuous phase. The effect of magnetization and Lorentz force on the continuous phase can be excluded to explore the mechanism of the electric field and magnetic field synergistic dehydration. Firstly, the particle size of droplets was characterized. The results showed that the dispersed phase was uniformly distributed and the average particle size was 18.24 um. Then the dehydration performance of different types of outfields was compared. The experimental results showed that the dehydration performance of AC electric field combined with magnetic field was better than that of single AC electric field. The dehydration performance of AC electric field and magnetic field was better than that of DC electric field and magnetic field. On this basis, the theory of AC polarization-electromagnetic force was proposed. Finally, the influence of magnetic field intensity on dehydration performance was explored, including dehydration depth and dehydration speed, and the optimal magnetic field intensity range in this experiment was obtained, and its value was [0.269, 0.355] T.
