DESIGN OF LIQUID-LIQUID-EXTRACTION COLUMNS POSSIBLE TEST SYSTEM ZN D2EHPA IN N-DODECANE/

A simple simulation study of the design of a liquid-liquid extraction column for the possible test system Zn/D2EHPA has been carried out. Th e results show the behaviour of different reaction kinetic models and the effect of the mass transfer coefficients on the column design. A c ontamination factor has also been used to determine the effect of chan ging mass transfer coefficients on the liquid-liquid extraction perfor mance. A sensitivity analysis has been carried out to determine which factors significantly influence the column design for a particular ran ge of conditions.
