3. A distillation column with a total condenser is using open steam beating to separate ethanol from water. Feed is 30 weights % ethanol and is at 20 C. Distillate is a saturated liquid of 80 wt.% ethanol. External reflux ratio is 1.15 times (LOD) min. Bottom is 5 wt. % ethanol. Input steam is pure water and is a saturated vapor. Pressure is 1 kg/cm? Equilibrium data is given in Figure 2-4 (a) Find (L.D) min and LD. (b) Plot Ap and Plot AB () Use the Ponchon-Savarit analysis to determine the number of equilibrium stages and find the optimum feed stage. 600 600 500) Destine. 500 Betriez line ict waterpolenta ceumarines composition 400 400 Enthalpy, kcal/kg. 300 300 89 901 985 1981 De ex 805 1sothermal to yine 40C 79.59 185 88+ 79- / 84 17765 78 83 78 200 200 Amalropis Composition 100 100 Boiling Ling IKG/19.com 100'da 80 601 40 201 Zoud OP Water o Fred Line Solid Ice OG -100 J-100 02 dz 0.8 d9 ds 04 ds db Concentration of Alcohol, Weight Fraction grybe
