I I ENGINEERING / ChEE. 2 A distillation column was designed to separate 424kg/hr feed (25C) contain 40 weight % methanol and remaining water, to produce distillate (38C) of 170kg/hr contains 97 weight % methanol and the residue (85C) contains 98 weight % water. Density of liquid =1005kg/m3. Cooling water enters at 25C and leaves at 35C. Column operates at 1atm and average temperature at 80C. Heat capacity of methanol and water are: 2530J/(kg.K),4.2kJ/(kg.K), respectively. Reflux ratio, Ro =5; Boiling point of 97mol% methanol is 65C. Latent heat of methanol and water at 65C are: 1085kJ/kg and 2500kJ/kg, respectively. Take flooding constant, Csbflood=0.12 and =20. Find (i) actual area of stripping section. (ii) the amount of heat removed from condenser
