Consider having a 700 mol/h feed entering a flash distillation unit or still under isothermal conditions containing 55 mole% of toluene and the rest of it is benzene. Operation of the still is at 760 torr. The equilibrium data for the benzene - toluene system approximated with a constant relative volatility of 2.5, where benzene is the more volatile component, a) Plot for the y - x diagram for benzene-toluene. b) If we desire a V/F of 0.60, what is the corresponding liquid composition and what are the liquid and vapor flow rates?

Briefly explain what is meant by “Control for Operability”.
