ABSTRACT

This study shows how dispersions consisted of droplet sizes ranging from 100 microns and above of immiscible liquids in agitated vessels coalesced and settled back to their phases by employing commercially known as knit-mesh made from stainless steel and nylon. These components known as higher surface energy and lower surface energy contained coalesce aids respectively. In addition, to compare, coalesce aid made purely from commercially known as duplex-nylon also used. The experimental set up was 1:3 scale of a single stage mixer-settler unit of the already existing unit which was in use at BNFL Springfield Works. The liquid –liquid system made from 20 % tri-butyl-phosphate (TBP) technical grade of odorless kerosene forming the light organic phase or solvent phase and, 5% M nitric acid forming the heavy aqueous phase. The solvent phase contained 70 gram of uranium per liter. Uranium contained phase was supplied by above mentioned company.
