Benzene toluene distillation column problem and solution (McCabe -Thiele method)

A benzene–toluene mixture containing 50 mol% benzene (xf) is to be separated in a distillation column with a reboiler and a partial condenser. The goal is to obtain: A distillate product containing 80 mol% benzene (xd) A bottoms product containing 15 mol% benzene (xw) The feed is a mixture of 50% saturated vapor, which means q=0.5. The reflux ratio (R) is 2.0, and the overall tray efficiency (ηtrays) is 50%. Tasks: 1. Find the number of actual trays required 2. Determine the feed tray location 3. Calculate the minimum reflux ratio #ChemicalEngineering #Distillation #McCabeThiele #EngineeringTutorials #ProcessEngineering
