5.118 One thousand kg h of an alcohol-water solution containing 50 weight\% alcohol is separated into a distillate containing 85 weight % alcohol and a bottoms containing 3 weight\% alcohol in a plate column at 101.3kPa. A total condenser is employed and the reflux ratio used is 1.5. The feed enters the column as saturated liquid. The equilibrium data (weicht fraction ethanol) are: Distiliation 443 The enthalpy data (weight fraction ethanol)are: Determine: (a) The amoums of distillate and residue, kg/h (b) The number of theoretical plates (c) Condenver and reboiler loads, ki/h (Answer: (a) D=573.17kg/h,B=426.83kgh (b) 3.8. (c) 1.528910kJ/h,I.544010kJ/h)
