Description

A liquid-liquid extraction for use for example, in the solvent extraction of uranium and/or plutonium from an aqueous phase, comprises a perforated plate packing in which each plate has flanges associated with its perforations, which flanges project upstream with respect to the disperse phase flow direction so as to define a collecting zone for disperse phase droplets which thereby form a film or layer of the disperse phase component on the upstream face of each plate. In this way, droplet formation at the perforations of each plate is not significantly influenced by variations of the wetting characteristics of the plate with time. (author)
