Abstract

The electric demulsification of oil-in-water (O/W) emulsion was investigated under the application of direct current pulsed electric field (DCPEF). The oil droplet movement behavior was observed by CCD camera and image acquisition and analysis system. And it was found that the DCPEF had an effect on the oil droplet coalescence, which led to the demulsification. Through the research on the dynamic behavior of oil drops under DCPEF, it was discovered that DCPEF could drive oil droplets to move and form oil droplet chains and oil clusters, which accelerated the demulsification process and conducted the oil-water separation. The results showed that DCPEF had distinct demulsification effect on O/W emulsion. And the optimal DCPEF parameters for oil-water separation were obtained that DCPEF voltage 1000v, frequency 25Hz and duty cycle 70% under the experimental conditions.
