| Abstract: | A novel method for breaking emulsions with microporous membranes is presented.A membrane would act as a coalescer if its pore size is smaller than the emulsion droplets and if the dispersed phase has great affinity to the membrane.It was observed that a hydrophilic membrane is able to break water in oil emulsions with high separation efficiency.Effects of the membrane pore size,membrane thickness,transmembrane pressure and emulsion composition on demulsification performance were investigated.It was found that the membrane pore size and transmembrane pressure affect demulsification performance remarkably while other factors have slight or almost no effect. |
