A mixture of ethyl alcohol and water with equimolar concentration is to be distilled in a seven plates column as a batch distillation with a reboiler at atmospheric pressure, if we neglect the residue liquid in condenser and reboiler, calculate :- A) State-1 (Constant XD).
The amount of distilled (D) and the a mount of heat required for ( 100 Kmole of Feed ) to get xD = 80 mole% , if R (reflux ratio must be increased till it reach=6.0 ) .
B) State-2 (Constant reflux ratio R).
The average value of xD (top product) & the a mount of heat if the concentration in the boiler must not less than 10 mole% ethanol if R is constant at = 4.0.
VLE for Ethanol-water are given in curve below:-
