Study on Demulsification Rate Under High Voltage Electric Field

A new mechnism of electric demulsification was proposed and the coalescence behavior of fine water drops in oil under electric field was discussed in detail. On the basis of this, a mathematical description for phase separation of emulsion in electric field had been derived and was in good agreement with experimental data. Influence of various conditions on electric coalescence was examined using a batch pulsed D. C. electric demulsifier.
