A distillation column is designed to separate a 100 mol/s feed of 50% benzene and 50% toluene. You specify both the distillate and bottoms products to be 90% pure, and the reflux ratio to be 2. You are tasked with designing the total condenser for this unit. In particular, you would like to calculate the required mass flow rate of cooling water (available at 25°C) that you'll need to supply the heat duty to the condenser. Engineers responsible for maintaining the cooling towers in your chemical plant specify that the cooling towers can handle water no warmer than 40°C. Hints: The vapor into the total condenser is at the dew point temperature. The liquid out is at the bubble point temperature. I have not supplied at least three physical properties (one each of benzene, toluene, and water) required to solve this problem. You will need to discuss which information you need and where to find it.
