A distillation column is used to process a feed stream containing 200 kgmole/hr of 52 mole % propane containing 70 % saturated vapor. (note: a binary equilibrium diagram is attached). A total condenser and a partial reboiler are employed in this system. The distillation tower has three exiting streams, a distillate product (xD=0.94), a saturated liquid sidestream(xS=0.68), and a bottoms product (xB=0.06). The sidestream total molar flow rate is 55 % of the distillate total molar flow rate. The heat duty in the reboiler is 400,000 kJ/hr and the heat of vaporization is 1080 kJ/kgmole. A cooling coil is placed in the column in such a way that 62.4 % of the vapor leaving the first actual tray from the bottom (not including the partial reboiler) is condensed. Construct a flow chart for this distillation column and determine the following (assuming constant molal overflow):

a) All external flow rates and compositions.

b) All internal flow rates.

c) Reflux in the condenser.

d) Heat duty in the condenser

e) On Figure 1 construct all appropriate operating lines and Q lines.

f) The number of stages and optimum location of the feed and the side stream.

g) The number of stages if the Murphree efficiency based on the vapor phase is 75%.
