A mixture of propane, butane and pentane are to be separated in a distillation column. Feed= Propane - 20 wt % Butane - 50 wt% Pentane - 30wt%. Top=Propane – 93 wt% Butane - 7 wt% Pentane – 0 wt%. Bottom=Propane - ?? wt % Butane - ?? wt% Pentane - 38 wt%. The weight % values shown are compositions. The total feedrate is 5000 kg hr-1. ALL the pentane is recovered in the bottom product, (comprising 38 wt% of the composition of that stream), determine the following:

(a) The total mass flowrates of each of the top and bottom product streams.

(b) The percentage recovery of the propane in the top product

A distillation column receives a feed that is 40 mole % n-pentane and 60 mole % n-hexane. The feed is saturated liquid at 2,500 lbmol/hr. The column is at 1 atm. A distillate that is 97 mole % n-pentane is desired. A total condenser is used. The reflux is a saturated liquid. The external reflux ratio is L0/D = 3. The bottoms from the partial reboiler is 2 mole % n-pentane. Determine the intersection (xq, yq) of the q-line with...

Multicomponent Distillation 1 A distillation column is separating ethane, propane, and n-butane at 5 atm. Operation is at total reflux. We want a 98.9% recovery of ethane in the distillate and a 99.8% recovery of n-butane in the bottoms. Propane is a sandwich component (e.g., in between light and heavy keys). The feed is a saturated liquid at 100 kmol/h composed of 30.0 mol% ethane, 33.0 mol% propane and 37.0 mol% n-butane. You may assume relative volatilities are constant, αEB...

A binary mixture of benzene and toluene will be separated by continuous distillation. The mixture consists of 20% mol of benzene and 80% mol of toluene at the bubble point of 91ºC. The binary mixture is available at 100 mol h-1 and the separation should deliver a distillate product that has a concentration of 90% mol of benzene and that contains half of the benzene in the feed stream. a) Plot the equilibrium line for benzene. b) Determine the minimum...
