3. Mass Transfer & Separation Q: Design a binary distillation column with reflux ratio R = 1.5 times the minimum. Feed is 50 mol% ethanol and 50 mol% water at bubble point, with distillate purity of 95 mol% ethanol and bottoms purity of 5 mol% ethanol. Using McCabe–Thiele method, determine the number of theoretical stages and feed tray location.
