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:
1497.6 . ,. . . .> ••• • • •
F • :BF = O.M •= 2340 kmoljhr (Et)lanolm Feed)
Total Material Balance:
F=D+S+B
F=1560+0.20F+B
0.80F−B=1560— (Eq. 1)
