A 50 mole% benzene-toluene mixture is separated on a continuous distillation column. Requirements of the distillation: xD=95 mole% benzene, XM-7 mole% benzene. The following data about the operation of the column are available: reflux ratio R = 3, feed is liquid at boiling point. Reflux is the result of total condensation. a) Assuming 100 kmol/h feed, what are the mass flows of the distillate and bottoms product? b) How many theoretical plates are required to achieve the separation? c) To which plate must the feed be introduced?

Answer rating: 100% (QA)

Solution to the image a To determine the mass flows of the distillate and bottoms product we can use the following mass balance equations F D B xF xD D xB B where F is the feed flow rate kmolh D is th... View the full answer
