An ethanol - propanol solution is to be separated in a plate rectification column at atmospheric pressure. The feed, of which is 50 mole percent vapor, contains 40 mole percent ethanol. 98 % of the ethanol should be recovered in the top product, which should be 95 % pure by mole. The column is provided with a total condenser and a kettle-type reboiler. If the feed rate is 200 kmol/h and the reflux ratio is set at 1.7 times its minimum value, reply the followings:
a) Draw schematically a column and show the currents and their compositions.
b) Calculate the flow rates of top and bottom products and the composition of the bottom product,
c) Write the equations of q-line, and enriching and stripping section operating lines.
d) Find the number of the ideal plates by using McCabe-Thiele Method.
e) Calculate the condenser and reboiler loads (duties) as kW.
Latent heat of vaporization of the solutions may be assumed constant at 47 000 kJ/kmol.

Homework Answers
from mole balance and material
balance all the values are calculated and also equations of all the
lines are calculated. And for option (d) relative volatility is
needed so that mc cabe thiele can be applied and plotted in graph
to find out number of tray

We are separating acetone and ethanol in a distillation column with a total condenser and a partial reboiler. The column has two feeds and operates at a pressure of 1.0 atm. Feed 1 is a saturated liquid that is 60.0 mol% acetone and has a feed rate of F1 = 200.0 kmol/h. The second feed is 40.0 mol% acetone, has a feed rate of F2 = 300.0 kmol/h, and is a two-phase mixture that is 20% vapor. Assume CMO is...

600 mol per hour of a mixture of acetone ethanol containing a 0.2 molar fraction of acetone was desired. The food enters as saturated liquid. A distillate with a mole fraction of 0.78 of acetone and a n.sls fraction in the bottoms of D.93 of ethanol can be obtained.
