2) 2-Propanol-Water Separation. A saturated liquid feed of 100 mol/hr containing 30 mole % 2-Propanol is to be fractionated at 101.325kPa (abs) in order to form a distillate containing 50 mole % 2-Propanol and a bottoms product of 2 mole % 2- Propanol. Experimental data (3 sources) for this system are provided. Determine a minimum reflux ratio (if possible) and design (size) the column using a reflux of 1.5 *RMIN (or suggest an appropriate reflux and unlnin the value you use for the system design).

2) 2-Propanol-Water Separation.
A saturated liquid feed of 100 mol/hr containing 30 mole % 2-Propanol is to be fractionated at 101.325kPa
(abs) in order to form a distillate containing 50 mole % 2-Propanol and a bottoms product of 2 mole % 2-
Propanol. Experimental data (3 sources) for this system are provided. Determine a minimum reflux ratio (if
possible) and design (size) the column using a reflux of 1.5 *RMIN (or suggest an appropriate reflux and
explain the value you use for the system design).
a) Calculate the flowrates (mol/hr) of the distillate and bottoms.
b) Determine the minimum reflux ratio, RMIN and the minimum number of theoretical trays at total reflux.
c) Determine the theoretical number of trays and the feed tray number for the specified operation al design.
d) If the column is 75% efficient how many actual stages will be required?
e) Using Raoult's Law (in other words using Antoine's correlation and assuming an ideal system)
recalculate and plot the Txy diagram at a total pressure of 101.325kPa, and
f) Plot the xy data for this system at a total pressure of 101.325kPa.
g) How well do the results of (e) and (f) compare to the experimental information?
h) Repeat parts (a) – (c) for the ideal system determined using Raoult's Law.
