A distillation column with a partial reboiler and a total condenser is being used to separate a Xmixture of Propane (1), Propylene (2) , and Butylene (3). The feed is 30.0% mole Propane, 30.0% mole Propylene and 40.0% mole Butylene. The feed is input as a saturated vapor. We desire 94.00% recovery of the Propylene in the bottoms and 98.50% recovery of the Propane in the distillate. The reflux is returned as a saturated liquid, and CMO can be assumed. Equilibrium can be represented as constant relative volatilities. Choosing Propylene (2) as the reference component, a12 = 1.48 and a32 = 0.65. Use a basis of 100 moles of feed/h. Use a %3D basis of 100 moles of feed/h. Assuming this system has a class II pinch possible roots (O) have been determined as 0.9321, 1.2962 and 1.5424. Find the minimum reflux ratio, Rmin:
