1.6-1. Use of Enthalpy-Concentration Method to Distill an Ethanol-Water Solution. A mixture of 50 wt \% ethanol and 50 wt \% water which 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 3 wt \% ethanol. The feed rate is 453.6kg/h and a reflux ratio of 1.5 is to be used. Use equitibrium 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 trys 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 (c) qc=698750kJ/h,qR=704770kJ/h A.3-23 Equilibrium Datu for Ethanol-Water System at 101.325kPa(1Atm) - Reference state for eathalpy is pure liquid at 273K or 0C.
