Question
A continuous distillation column is to be used to separate a binary mixture containing 38% mol fraction of
compound A and 62% mol fraction of B to produce a top product containing 10% mol fraction of less
volatile component (B) and a bottom product containing 6% mol fraction of compound A. The feed is 35%
vaporized and is introduced at a rate of 100 mol/h and the column is operated at reflux ratio of 3. A side
stream is withdrawn containing 20% of A in the feed forming 60% of the side stream. The equilibrium data
for the system is given below:
X 0.00 0.21 0.40 0.56 0.81 1.00
Y 0.00 0.42 0.63 0.75 0.90 1.00
a) Determine the number of theoretical stages required.
b) Using Lewis Sorrel method, calculate the composition of liquid on the second plate from the top
