A distillation column has two feeds. Feed F1 is 80kmol/ hour and is a two phase mixture, 45% methanol. Feed F2 is a saturated vapor, 100kmol/hr 20 mol% methanol. We desire a distillate of 95% xb=5% methanol. Reflux is returned as a saturated liquid pressure is 1atm. L/D= 1.375. Assume CMO. Find the optimum feed locations (reported as stages above the reboiler) and the total number of equllibruim stages required. Show ALL steps please
