A distillation column is separating methanol from water at 1 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 (see below). The feed flow rate is 2000kmol/day. The feed is 48mol% methanol and the condition is such that for every 4 moles of feed, 1 mole of vapor must condense inside the column. The desired distillate composition is 92mol% methanol, and the bottoms is 8mol% methanol. The reflux is saturated and the reflux ratio is 1.0. The boilup ratio is 0.5. Assume CMO is valid. Find the optimum feed plate location and the total number of equilibrium stages required. Equilibrium data can be found in problem 7.19.
