3. Given the equilibrium data for acetone from ethanol at 1 atm below, 0.262 0.15 0.348 0.417 0.25 0.478 0.524 0.35 0.566 0.605 0.674 0.739 0.802 0.865 0.929 0.1 0.3 0.6 0.7 0.9 Answer the following: A distillation column with a total condenser is separating acetone from ethanol. A distillate concentration of 90 mo1% acetone is desired. Since CMO is valid, LN is constant at 0.80, find the composition of the liquid leaving the 5th stage below the condenser a. b. A distillation column separating acetone and ethanol has a partial reboiler that acts as an equilibrium contact. If the bottoms concentration is 13 mol%) acetone and the boilup ratio equals 1.0, find the vapor composition leaving the second stage above the partial reboiler The distillation column in parts a and b is separating acetone from ethanol and has a 90 mol% distillate concentration and 13 mol% bottoms concentration ethanol. The internal reflux ration is 0.8 and the boilup ratio is 1.0. If the feed contains 30 mol% ethanol, find c. i. optimum feed plate location, ii. total number of stages iii. required feed quality (q-value) of the feed. iv. Number of stages required at total reflux. v. Minimum internal reflux ratio, and minimum external reflux ratio.
