RATE MODEL FOR PHASE SEPARATION OF WATER - IN-OIL EMULSION IN LIQUID SURFACTANT MEMBRANE PROCESS AT HIGH A.C. VOLTAGE

摘要

A new mechanism of electric demulsification was proposed and the coalescence behavior of fine waterdrops in oil under electric field was discussed in detail On this basis,a mathematical description for phaseseparation of emulsion in electric field has been derived and proved to be in good agreement with experimentaldata.Conditions influenced the electric coalescence was examined in a batch pulsed A.C.electric demulsifier.
