A compeny decides 10 reoover the ethanol from theif ethanol-water misture by using distillation process. The feed which contains 50 wt \% ethanol and 50 wt \% wrier is to be distilled at 101.325 kPa preseure. The distillate ecetains fos wt % cthanol and the botion contain 3 wt % cthanol. The fect rase is 10,000kg and and eathalpy is 120k/kg. Use ecasistent unis of kg/h, weight fraction and k/kg. The equillbriam data for ethanol-water system at 101.325kPa (1 atm) is provided in Table 1 . Table 1: Equilibrium Data for Ethanol-Water System at 101.125kPa (1 atm) (a) Plot the xA versus yA, and the cnthalpy concentration graphs and calculate the amount of distillate and bottoms.
