Minimum number of trays

100 kmol/hr of a feed of 60% benzene and 40% heptane is to be separated by distillation. The distillate is to be 90% benzene and the bottoms 10% benzene. The feed enters the column as 30 mol% vapor. Use R 1.5 times the minimum. Assume a constant relative voltaility of (alpha) of 4 and that the pressure is constant throughout the column at 1atm.

A distillation column has a feed of 100 kmol/h. The feed is 15 mol% heavy non-key, 35 mol% heavy key, and 50 mol% light key. The reflux ratio is 1.4 times the minimum. It is desired to have 99% recovery of the light key in the distillate. The mole fraction of light key in the distillate should be 0.85. Use the FUG approach to determine the number of ideal stages required. Equilibrium data: aLNK =3.5 aLK =1.5 aHK =0.85

We wish to separate a mixture of 60 mol% ethanol and 40 mol% n-propanol in a distillation column with a partial reboiler and a total condenser. The feed rate is 1000 kmol/h, and feed is a saturated vapour. We desire a distillate product of 99 mol% ethanol and a bottoms product that is 0.8 mol% ethanol. Reflux is saturated liquid and CMO can be used. Equilibrium data can be approximated with an average relative volatility of 2.1 (ethanol is more...

1.   The liquid product from a flash distillation has a mole fraction of the more volatile component that is lower than the specified liquid purity. Should we decrease, increase, or hold constant the vapor molar flowrate to meet the specified liquid purity? Draw a sketch and explain why? 2.   If the reflux ratio increases, do the molar flowrates for the distillate, bottoms, reflux, and overhead vapor decrease, stay the same, or increase?
