A mixture, F, of 620 lbmol/h of 46 mol% benzene (B) and 54 mol% toluene (T) is separated continuously into two products. One product, the distillate , is 98 mol% benzene. The other product, the bottoms , is 95 mol% toluene. Compute the flow rates of these two streams in: (a) lbmol/h, and (b) kmol/h. Calculate the fraction of the benzene fed to the unit that is recovered in the distillate.

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.

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...

A liquid stream has a flow rate of 100 mol/min and contains 25 mol% Stanzium and 75 mol% water. Stanzium is foul and disgusting and nobody wants that stuff in their water, so an extraction process is used to purify the water. The liquid enters the extraction unit, as does 400 mol/min of a solvent stream, which contains 98 mol% hexane and 2 mol% Stanzium. The water and hexane are completely immiscible, though the Stanzium is soluble in both. The...
