We want to separate 45 kg/hr of 50 mol % benzene in toluene entering as a saturated liquid into streams of 85 mol% benzene and 90 mol% toluene. 1. What is the minimum number of theoretical (equilibrium) stages required to achieve this separation? 2. What is the minimum reflux ratio? 3. If 3x the minimum reflux ratio is used, what is the required number of equilibrium stages, and where should the feed stage be located? 4. What is the mass flow rate of the product streams for the situation given in part 3? Also report the composition (mole fraction of light key) of the bottoms stream given the number of equilibrium stages you report in part 3.
