A vapor mixture containing 24.1 mol% benzene (C6H6), 40.8 mol% toluene (C7H8 MW=92), and the balance xylene (C8H10 MW=106) is fed to a distillation column. The feed is an ideal gas at 195oC and 5.37 psig flowing at 2.58 m3/hr . The column runs at steady state. All of the xylene is recovered in the bottom product making up 47.2 mol% of the bottom product stream. The recovery of benzene in the overhead is 65.3% (by moles).

(a) Draw the process flow diagram. Number the streams.

(b) Calculate the exiting flow rates (mol/hr) and mole fractions.

(c) The temperature of the inlet stream increases by 100K. Will the molar flow rate of the inlet stream increase, decrease, or stay the same?
