1. Consider a distillation column for separating ethanol from water at 1 atm. Thefollowing specifications are set:Feed: 10 mol% ethanol (bubble-point liquid)Bottoms: 1 mol% ethanolDistillate: 80 mol% ethanol (saturated liquid)Reflux ratio: 1.5 times the minimumConstant molar overflow may be assumed and vapour-liquid equilibrium data aregiven in Question 1.
a. How many theoretical plates are required above and below the feed if a platecolumn is used?
b. How many transfer unis are required above and below the feed if a packedcolumn is used?
c. Assuming that the plate efficiency is approximately 80% and the plate spacingis 18 in., how high is the plate column?
d. Using an HOG value of 1.2 ft., how high is the packed column?
e. Assuming that you had HTU data available only on the benzene-toluenesystem, how would you go about applying the data to obtain the HTU for theethanol.
