A continuous steady-state distillation column with a total condenser and a partial reboiler is separating 1-butanol from cyclohexanol at 1 atm. 1000 kmol/h of the said binary mixture consisting of 45 mol% 1-butanol is being fed to the column. It is desired to have a distillate product that is 95 mol% 1-butanol and a bottoms product that is 2 mol% 1-butanol. Assume CMO. The reflux ratio and the boil-up ratio are 1.30 and 1.80, respectively. a) Perform mass balances to plot the enriching section, stripping section, and the feed line. b) What type of feed is used in the column? c) Find number of ideal stages for desired separation and the optimal feed tray location.

A continuous steady-state distillation column with a total condenser and a partial reboiler is
separating 1-butanol from cyclohexanol at 1 atm. 1000 kmol/h of the said binary mixture
consisting of 45 mol% 1-butanol is being fed to the column. It is desired to have a distillate product
that is 95 mol% 1-butanol and a bottoms product that is 2 mol% 1-butanol. Assume CMO. The
reflux ratio and the boil-up ratio are 1.30 and 1.80, respectively.
a) Perform mass balances to plot the enriching section, stripping section, and the feed line.
b) What type of feed is used in the column?
c) Find number of ideal stages for desired separation and the optimal feed tray location.
d) Determine the concentration of the mixture at each stage.
e) Calculate the flowrates of the distillate and bottoms, as well as the reflux and boil-off.
f) Find the minimum number of stages required to achieve the desired separation.
g) Find the minimum reflux ratio.
If needed below is the graphs.
