Murphree point efficiencies in multicomponent systems

Abstract

The mass transfer characteristics during distillation of n-component mixtures on a well-mixed tray are analysed using matrix formulations of the interfacial transport rate relations. The Murphree point efficiencies of individual components are seen to be capable of exhibiting bizarre behaviour (E_oyi ⋍0; E_oyt< 0; E_oyi>1 E_oyt± ∞) arising out of diffusional interaction effects in multicomponent systems.
