A fractionation column operating at 101 kPa is to separate 30 kgh of a solution of benzene and toluene containing 0.6 mass-fraction toluene into an overhead product containing 0.97 mass-fraction benzene and a bottoms product containing 0.98 mass-fraction toluene. A reflux ratio of 3.5 is to be used. The r feed is liquid at its boiling point, feed is to the optimal tray, and the reflux is at saturation temperature.

(a) Determine the quantity of top and bottom products

(b) Determine the number of stagesrequired.
