Hello Pink Rose,

I've had a similar project assigned to me, in order to comprehend some of the basics of distillation I've made an Excel file which applies the Fenske, Underwood, & Gilland (FUG) Method to calculate some things. It's not completed yet since a part of the batch distillation calculations are not done yet, but perhaps it is of interest to you aswell.

Edit: it does not consider azeotropes but should give you a general insight into distillation calculations.

Ethanol & Water will form an AZEOTROPE so, you have to add a solvent Toluene for this.

During my graduation final semester seminar & project was on AZEOTROPIC DISTILLATION.

There are other possibilities, consider mol sieve / ceramic membranes.
