6.7-1. Use of the Enthalpy-Concentration Method to Distill an Ethanol-Water Solution. A mixture of 50wt% ethanol and 50wt% water that is saturated liquid at the boiling point is to be distilled at 101.3kPa pressure to give a distillate containing 85wt% ethanol and a bottoms containing 3wt% ethanol. The feed rate is 453.6kg/h and a reflux ratio of 1.5 is to be used. Use equilibrium and enthalpy data from Appendix A.3. Note that the data are given in wt fraction and kJ/kg. Use these consistent units in plotting the enthalpy-concentration data and equilibrium data. Do as follows: (a) Calculate the amount of distillate and bottoms. (b) Calculate the number of theoretical trays needed. (c) Calculate the condenser and reboiler loads. Ans. (a) D=260.0kg/h,W=193.6kg/h (b) 3.9 trays plus a reboiler
