Show transcribed image text A column with a partial reboiler and a total condenser is distilling hydrocarbons at 7,0 bar. The saturated liquid feed is 25.0 mol% ethane, 35.0 mol% n-butane, and 40.0 mo1% n-pentane, and the flow, rate is 100.0 kmol/h. Recover 992% of the n-butane E2. and L /D = 30. Find the optimum feed stage and the total number of equilibrium contacts required. Assun spr of the n-pentane in bottoms. The reflux is a saturated liquid e CMO, and use DePriester charts or Eq. (2-28). Use of a eadsheet to do dew-point calculations is highly recommended
