✦ Synopsis

A quantitative comparison between Murphree and vaponzatlon efficlencles IS presented based on ternary chstdlatlon data for the systems acetone/methanol/ethanol, acetone/benzene/chlorobenzene, benzene/toluene/mxylene and n-hexanelmethylcyclopentanelbenzene The Influence of expenmental errors on calculated values of Murphree efficiencies IS also analysed It IS shown that the vaporlzatlon efficiency model fads to descnbe the hehavlour of dlstdlatlon plates and It IS suggested that Murphree's model grves a more useful representation of the behavlour of dlstdlatlon columns

## Abstract A first approximation to the multicomponent plate‐efficiency problem has been carried out with a film model combined with equations for steady state diffusion in a ternary gas mixture. Numerical integration of the equations through a plate yields the ternary efficiencies as functions of
