Prediction of Multicomponent Point Efficiency

1 Difference Between Binary and multicomponent Point Efficiency 

The separation efficiency in multicomponent distillation is quite different with that 

In binary system, the diffusion flux between liquid and vapor phases is proportional to the negative concentration gradient, while it is not true in multi-component system. 

In binary system, the diffusion coefficient for components i and j is equal, while in multicomponent it is not equal. 

In binary system, the range of point efficiency is from 0 to 1, while it is ranging from —00 to +00 for multicomponent system.
