ChE 150B Problem Set 8 Due October 22, 2010 1. (40 points) Vapor-liquid equilibrium data for mixtures of water and isopropanol at 1 atm (101.3 kPa, 760 torr) are given below. (a) Prepare T - X-y and x-y diagrams. (b) When a solution containing 40 mol% isopropanol is slowly vaporized, what will be the composition of the initial vapor formed? (c) If this same 40% mixture is heated under equilibrium conditions until 75 mol% has been vaporized, what will be the compositions of the vapor and liquid produced? VAPOR-LIQUID EQUILIBRIUM FOR ISOPROPANOL AND ATER AT 1 ATM Mol% Isopropanol T , °C Liquid Vapor 93.00 1.18 21.95 89.75 3.22 32.41 84.02 8.41 46.20 83.85 9.10 47.06 82.12 19.78 52.42 81.64 28.68 53.44 81.25 34.96 55.16 80.62 45.25 59.26 80.32 60.30 64.22 80.16 67.94 68.21 80.21 68.10 68.26 80.28 76.93 74.21 80.66 85.67 82.70 81.51 94.42 91.60 Notes: Composition of the azeotrope: x =y = 68.54% Boiling point of azeotrope: 80.22 ° C Boiling point of pure isopropanol: 82.5 ° C.
