Benzene-Toluene Separations. We wish to separate benzene from toluene in a sieve-plate distillation
column with a total condenser and a partial reboiler. There are two feed streams:
Feed Flowrate (mol/hr)
300
Thermal State
ZE
1
0.36 saturated vapor
0.72 saturated liquid
2
700
The column designed is intended to provide a bottoms product that is 4% (mol) benzene and the
distillate should be 94% (mol) benzene.
Notes:
The reflux ratio is equal to (1.0) and the feeds are to be input at their optimum location(s).
Consider two column designs --- one in which each feed enters at the most appropriate stage/location
and the second in which the feeds are combined into a single stream (you will need to calculate/estimate
the feed q condition!) and sent into a column.
Equilibrium data for benzene-toluene at atmospheric pressure is available.
You may also identify / use other experimental data (web sources, library) for this system.
a) What are the flowrates of the distillate and bottoms products?
For a two feed design:
b) What are the liquid and vapor flowrates in the stripping and rectification sections of the column?
c) What are the flowrates of liquid and vapor on stages between the two feed points?
d) Determine the number of equilibrium stages required for the separation.
