ABSTRACT
This chapter describes a new approach to the organization of mass transfer processes in ion exchange and sorption beds. The approach consists in reducing the space occupied by water and working solutions in the columns by using an additional liquid phase. The chapter demonstrates the prospects of the proposed approach by a variety of actual examples for chemical engineering and elemental analysis. A new approach to the treatment of highly concentrated solutions of electrolytes in ion exchange and sorption columns with zero bed porosity is proposed. It is interesting to understand how the presence of an additional liquid phase in a column and the absence of the inter-particle space in sorption bed affect the results of simple ion exchange process. The advantages of this new approach, which makes it possible for the decrease in the duration of cyclic processes, reducing the longitudinal dispersion effects in dynamics in columns, reduction in special requirements for facilities and their cheapening.
