please q3&4

Q1 (82 points) A saturated liquid feed (600 kg/h) containing 30 wt% ethanol and 70 wt% water is to be separated in a distillation column at 101.3 kPa. The bottoms product contains 0.05 wt% ethanol. The vapor distillate from a partial condenser is 85 wt% ethanol. Reflux is a saturated liquid, and the reflux ratio (L5/D) is 3 (by mass) Note: 1. Use the given enthalpy-composition diagram to find compositions, if needed. Clearly indicate the data found inside the diagram. 2. Use the given enthalpy-composition diagram to find enthalpies, if needed. Clearly indicate the data found inside the diagram. 3. Use the given enthalpy-composition diagram to find compositions, if needed. Clearly indicate the data found inside the diagram. 4. If a tie line is required, clearly show that using the auxiliary line inside the given enthalpy- composition diagram. 1.1 un 3. Calculate the heat duty of the reboiler. (10 points) 4. What is the expected temperature of the partial condenser? (10 points)
