Influence of the diffusion pattern of the liquid phase flow on ion exchange in a continuously operated countercurrent apparatus

Summary

Physical and mathematical models of a continuously operated ion-exchange apparatus with plug flow of ionite granules and diffusion flow pattern of processed liquid are compiled. It is shown that in this case the operating line becomes curved and inverted to the direction of the equilibrium line. The algorithm of ion-exchange apparatus calculations is presented. Linear approximation of the equilibrium line was carried out that provided for obtaining a differential equation of second order which had an analytical solution. The comparative results of designing an ion-exchange apparatus with plug flow of both phases with different flow patterns are presented.

Key words
