Problem 1. (30 points). A 100 mol/hr solution comprised of 60 mol % benzene, 25 mole% toluene, and
15 mol% xylene is to be separated by a column. There are three exiting streams, n1, n2, and n3. Their
specifications are listed below.
•
n??80 mol% benzene and 16 mol% toluene
•
n??50 mol% benzene and 23.3 mol% toluene
•
n??25 mol% benzene and 50 mol% toluene
a. Draw a schematic of the process (5 points).
b. What is the flow rate (mol/hr) of streams n1, n2, and n3? (25 points)
