A tray distillation column tower is to be designed to distill 550 Ibmol/h of a binary mixture of 50 mole % benzene and 50 mole % toluene. A liquid distillate and a liquid bottoms product of 95 mol % and 5 mol % benzene, respectively, are to be produced. The feed is pre-heated so that it enters the column with a molar percent vaporization equal to the distillate-to-feed ratio. Use the McCabe-Thiele method to compute the following, assuming uniform pressure of 1 atm throughout the column: (a) (b) (c) (d) Minimum number of theoretical stages; Minimum Reflux Ratio; Number of equilibrium stages for a reflux-to-minimum reflux ratio of 1.3; and Optimum location of the feed stage The Antoine Equations of State for Benzene and Toluene are as follows: LogioPvap = A- B/(t + C) where Pvap is n mm Hg, t is in deg C B 1211.033 Chemical Formula Range, deg C A Benzene 220.790 6.90565 6.95334 Toluene C>Hs 1343.943 219.377 Tips for charting: To draw a diagram, you need to consider several temperatures and obtain the vapor pressure of each component for these temperatures. These temperatures must be between the boiling range of two substances, benzene and toluene. Because you have considered a few temperatures, how many values are obtained for the volatility coefficient or alpha, and after the obtained alphas, you average and use the average alpha as the basis for drawing the graph.

Transcribed Image Text:A tray distillation column tower is to be designed to distill 550 Ibmol/h of a binary mixture of 50
mole % benzene and 50 mole % toluene. A liquid distillate and a liquid bottoms product of 95
mol % and 5 mol % benzene, respectively, are to be produced. The feed is pre-heated so that it
enters the column with a molar percent vaporization equal to the distillate-to-feed ratio.
Use the McCabe-Thiele method to compute the following, assuming uniform pressure of 1 atm
throughout the column:
Minimum number of theoretical stages;
(a)
(b)
(c)
(d)
Minimum Reflux Ratio;
Number of equilibrium stages for a reflux-to-minimum reflux ratio of 1.3; and
Optimum location of the feed stage
The Antoine Equations of State for Benzene and Toluene are as follows:
LogioPvap = A- B/(t+ C) where Pvap is n mm Hg, t is in deg C

Tips for charting:
To draw a diagram, you need to consider several temperatures
and obtain the vapor pressure of each component for these
temperatures. These temperatures must be between the boiling
range of two substances, benzene and toluene.
Because you have considered a few temperatures, how many
values are obtained for the volatility coefficient or alpha, and after
the obtained alphas, you average and use the average alpha as the
basis for drawing the graph.
