Q2: A fractionation column is required to distill a liquid containing 22 %
benzene and 78 % toluene by weight so as to give a product of 93 %
benzene by weight and a bottom product of 3 % benzene by weight. A
reflux ratio of 3.6 is to be used, and 100 kmol/hr. of feed will enter at its
boiling point.
1- Find by stage to stage calculation the composition of liquid on the fifth
stage.
2- Calculate the number of stage required at rectifying section (by stage
to stage calculation).
M. Wt. of benzene = 78, M. Wt. of toluene = 92. The equilibrium data are:
X 0.1 0.20 0.3 0.4 0.5 0.6 0.7 0.8 0.9
Y 0.22 0.38 0.52 0.63 0.7 0.78 0.85 0.925 0.96​
