System: Ethanol - Water

 

Description of the exercise:

Question 1: Do a distillation with total reflux and estimate average plate efficiency as a function of vapor speed.

Question 2: Measure the pressure drop over the column for different vapor speeds and find capacity borders (lower and higher).

Question 3: Do a ‘binary-batch’ distillation with given reflux and reboiler duty. Decide distillate composition as a function of n/n0.

n = total number of moles back in reboiler + column.

n0 = total number of moles at the beginning of the experiment.
