Communications Phase Separation Technique for Liquid Dispersions

A new technique Is developed to obtain the constituent liquids of a two-phase liquid dispersion from a continuous flow stirred tank extractor. The phase separation required for solute mass transfer estimation is achieved by in situ filtration of the stirred tank dispersion. The in situ filtration through an extremely thin membrane renders the separation almost instantaneous and eliminates the possibility of additional mass transfer during the separation. The technique is also well suited for continuous on-line monitoring of solute concentration and is superior to previous methods reported in the literature.
