Abstract

The emulsion is passed and recycled at high speed, e.g. 20 cycles per hour, through a very fine filter and this renders the emulsion highly unstable mechanically so that it can be readily sepd. into 2 phases by filtration, through a slow, fine filter or by centrifuging or flotation. When an emulsifying agent has been used, this can be neutralised chemically before the sepn. process.
