Question: a distillation column with a total condenser and a partial reboiler is separating isopropyl alcohol(1) and water (2) at 2.4 atm. Feed is 30 mol%

a distillation column with a total condenser and a partial reboiler is separating isopropyl alcohol(1) and water (2) at 2.4 atm. Feed is 30 mol% ethanol and it enters as a saturated liquid at 2.00 mol/s on the optimum plate. The distillate is a saturated liquid with 62 mol % ethano. hl=18.6 kj/mol , Hv=57.22 kj/mol. The actual reflux ratio (R=L/D) is exactly double the minimum and bottoms composition is 8 mol% isopropyl. find the minimum reflux ratio, rmin.
