Problem 2.6: (45 marks) A liquid mixture containing 38 mol% benzene (B), 35 mol% toluene (T), and 27 mol% xylene (X) is fed to a distillation column. The bottom product contains 97 mol% X and the balance is T, bearing in mind that 93% of X in the feed is recovered in this stream. The overhead product is fed to a second column. The overhead product from the second column contains 95 mol% B and 5 mol% T, bearing in mind that 96 mol% of the benzene fed to the system is recovered in this stream. Draw and completely label a flow sheet of the process, and perform a degree of freedom analysis for each control volume (in total 3 control volumes)
