If the bottoms composition is xB = 0.13 mole fraction acetone and theД«oilup ratio /B = 1.0, find the vapor composition leaving the second stage above the partialД¬. A distillation column separating acetone and ethanol has a partial reboiler that acts as anД®quilibrium contact. If L/V is equal to 0.8, find the composition of the liquid leaving the fifth stage belowД«. A distillateД¬oncentration of xD = 0.90 mole fraction acetone is desired. A distillation column with a total condenser is separating acetone from ethanol. If F = 50 mol/h, z = 0.8, p = 1 atm, and ym = 0.892 mole fraction methanol, find V, L, and xm.ДЄ. If z = 0.4, p = 1 atm, and Tdrum = 77вЊ, find V/F, xm, and ym. What must the flow rate and composition of the feed be?ДЇ. We are operating the flash drum so that the liquid mole fraction is 45 mol% methanol. V/F must be used? For a feed rate of 1000 lbmol/h, find product flow rates and compositions.Д. If the feed is 30 mol% methanol and we desire a liquid product that is 20 mol% methanol, what Mole fractions and flow rates? Feed rate is 100 kmol/h.Д¬. Feed is 60 mol% methanol, and 40% of the feed is vaporized. We are separating a mixture of methanol and water in a flash drum at 1 atm pressure. HowД¬an you get the composition from P and T? Setting the pressure and temperature also specifies the equilibrium composition. This part is sort of backwards (feed composition is not specified). Which variables have been specified, and how doesД.

Which two variables (besides the feedД¬omposition) have been specified? The drum just separates the vapor from the liquid.Д¬.
