DIFDIST - Multicomponent Differential Distillation

A mixture of hydrocarbons A, B, C and D is charged to a still pot and distilled over in the absence of reflux. 

Vary the relative volatilities of the mixture and study the effect on the distillation. 

Compare the computer predictions with the Rayleigh equation prediction, where  

Check the overall material balance in all the above exercises. 

Using the interact feature of ISIM, make an additional charge to the still at
