dc.description.abstractA novel process is described in which the resolution of a stable water-in-oil emulsion is augmented by the simultaneous use of pulsed DC electric 1elds and mild bubbling of the emulsion with air. The work has indicated that there is a synergistic effect of air sparging on demulsi1cation in the electric 1eld and that the maximum emulsion resolution requires the voltage to be pulsed with optimum frequency. Emulsion resolution was found to increase steadily with increasing air 5ow rate until a maximum value is reached after which the extent of phase separation starts to fall rapidly with further increase in the air 5ow rate. The electrical resolution was best (79% resolution) when the ratio of air to emulsion 5ow rate (volumetric) in the coalescer was about 120 : 1.en_US
