Thermodynamic Work of Separation in a Cascade System in Processing a Multicomponent Mixture

The possibility of calculating thermodynamic work of separation W T,K for a complex of cascades consisting of earlier described stages of equilibrium separation with semipermeable plungers is illustrated by the processing of a four-component mixture. It is found that work W T,K can be considered as sum Σ W T,K mk, where W T,K mk corresponds to selected pairs of components ( m, k ) in a multicomponent mixture. The proposed procedure for calculating W T,K is spread into combinations of 8, 16, or even more components, and into extraction and chromatographic systems of fractioning.
