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 ΣW_T,Kmk, where W_T,Kmk 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.
