Condenser Rellus column A distillation column, as shown in the figure, is a device used to separate components with different volatilities. In a specific process, a distillation column is used to separate a feed stream containing 0.4300 mol ethanol/mol and 0.5700 mol water/mol into two product streams: an overhead stream that is ethanol-rich and a bottoms stream that is water-rich. Vapor containing 0.7860 mol ethanol/mol and 0.2140 mol water/mol leaves the top of the distillation column and enters a Overhead product condenser, where the stream condenses completely into a liquid. This stream Food Distillation is then split; the reflux returns to the column, and the overhead product leaves the process. The ratio of the flow rates of reflux to overhead product Boilup is given by the reflux ratio R= flow rate of reflux flow rate of overhead product and for this particular process, R = 1.37. Liquid leaving the bottom of the Bottoms product distillation column enters a reboiler, where a fraction of the stream is vaporized and returns to the distillation column as boilup, while the liquid fraction leaves the process as bottoms product. The composition of the boilup and the bottoms-product streams are governed by the relative volatility, a, of ethanol and water. Reboller Yw/xw yt/XE (1 - y)/(1 - XE) ye/(1 - Ye) XE (1 - XE) where ye is the mole fraction of ethanol in the vapor stream, yw is the mole fraction of water in the vapor stream, Xp is the mole fraction of ethanol in the liquid stream, and Xw is the mole fraction of water in the liquid stream. For this particular process a = 10.575, and the ratio of ethanol leaving the reboiler in the boilup to ethanol leaving the reboiler in the bottoms product is 0.650. For a basis of 100 mol of feed, 53.59 mol of overhead product is produced. Given this basis, answer the questions. Label the process flow diagram. Label any quantities as "unknown" if they are not given or implied. Do not leave any blank spaces. Variable names are given for reference later. mol Condenser mol E/mol mol W/mol (1 - y) = Overhead product Reflux mol mol Feed mol E/mol mol E/mol mol W/mol mol mol W/mol Distillation column X, (1-2) mol E/mol mol W/mol Boilup mol Answer Bank y, (1 - y) = mol/mol mol W/mol 1.37 53.59 10.575 100 Bottoms product Reboiler mol 0.4300 unknown 0.2140 mol mol E/mol mol W/mol mol E/mol mol W/mol 0.7860) 0.650 0.5700 (1-x) = Given the basis, what is no, the moles of bottoms product? mol What is X6, the mole fraction of ethanol in the bottoms product?
