A distillation column is separating methanol from water at a pressure of 1.0 atm. The column has a total condenser and a partial reboiler. In addition a saturated vapor stream of pure steam is input on the second stage above the partial reboiler.The feed flow rate is 2000.0 kmol/day. Feed is 48.0 mol% methanol and 52.0 mol% water and is a subcooled liquid. For every 4.0 moles of feed, 1.0 mole of vapor must condense inside the column. Distillate is 92.0 mol% methanol. Reflux is a saturated liquid, and L 0 /D = 1.0. Bottoms is 8.0 mol% methanol. Boilup ratio is =V / B 0.5. As- sume that CMO is valid. Find the optimum feed plate location and the total number of equilibrium stages required.
