 QUESTION 1

1. Overall Material Balances

Given Data:
 Distillate flow rate (D) = 1560 kmol/hr
 Mole fraction of ethanol in distillate (xD) = 0.96
 Mole fraction of ethanol in bottoms (xB) = 0.09
 Mole fraction of ethanol in side stream (xS) = 0.70
 Side stream flow rate (S) = 0.20F
 Ethanol recovery (Rec) = 64%=0.64

Ethanol Recovery Equation:
The amount of ethanol in the distillate is 64% of the ethanol in the feed:
