You can assume constant molar flow rates 3. A saturated vapor feed that is 90 %mol maleic anhydride and 10%mol benzoic acid is distilled at 99.8 torr to give a distillate that is 99.5 %mol maleic anhydride and a bottoms that is 0.5 %mol maleic anhydride. How many equilibrium stages are needed using a reflux ratio that is 1.6 times the minimum? The solution is ideal in both vapor and liquid stages. Vapor pressures can be estimated with the following Antoine equations in °C and torr:

You can assume constant molar flow rates 3. A saturated vapor feed that is 90 %mol maleic anhydride and 10%mol benzoic acid is distilled at 99.8 torr to give a distillate that is 99.5 %mol maleic anhydride and a bottoms that is 0.5 %mol maleic anhydride. How many equilibrium stages are needed using a reflux ratio that is 1.6 times the minimum? The solution is ideal in both vapor and liquid stages. Vapor pressures can be estimated with the following Antoine equations in °C and torr: Maleic anhydride: Pº = exp (16.6541 Benzoic acid: Ps = exp (23.0155 4088.12 T+203.924 9336.97 T+321.434
