13 48,045ABSTRACT OF THE DISCLOSUREA method of recovering liquid from an emulsionformed in a liquid-liquid contacting process, where theemulsion comprises at least one of the liquids entrappedby water-permeable membranes, comprises: admixing waterand the emulsion in a volume ratio of water emulsion ofbetween 0.5 to 4.5:1 and raising the temperature of theadmixture to between about 45°C and 99°C, to cause waterpermeation of the membranes, causing them to disintegrateand release liquid, forming a three-phase compositionconsisting essentially of the two liquids and the solids.
