✦ Synopsis

The processes of substances' separation are a basis of numerous chemical technologies applied in various spheres of human activity. The majority of methods for separation of homogenous mixtures (liquid, gas, and fluid extraction; static and dynamic sorption; and chromatographic methods) are based upon differences in the interphase distribution of the substances. Presently, all possible phase combinations have been implemented in these methods. But the conceptual schemes for the realization of interphase distribution process are invariable: mixing and separation of phases or creation of one phase flow in regard to another, stationary phase. Regardless of the phase system used, any of those schemes allows the realization of the separation process with periodical injection of initial mixture and periodical extraction of final products. In those rare cases when continuous separation is possible-in countercurrent extraction for exampleseparation of phases in the flow causes serious problems. Hence, one encounters objective difficulties
