An aqueous solution of methanol is being separated by distillation in a column. Methanol (A). which is the more volatile component, moves from liquid phase to the vapor phase while water (B), the less volatile component, moves from vagor phase to the liquid phase. At a section of the column, the vapor phase contains 70 mol% methanol and the liquid phase has 40 mole% of water. The diffusion takes place in Imm thick stagnant vapor layer between the liquid and vapor phases. The temperature is 75 C and the total pressure is 1 atm: The vapor pressure of methanol is 1.5 atm and its diffusivity through water is 1.82 x105 m/s. The fluxes are related through the heat released during the vaporization/condensation in the distillation process: NAAHX=-NAH: the heat of vaporization are 8787 kcal/kmol for methanol and 10039 kcal/kmol for water. Perform the following: a) Draw a schematic diagram (2 point) b) list all assumptions required (2 points) c) Develop and simplify the differential flux equation of methanol (8 points) d) What are the boundary conditions? (2 point) e) Determine the fluxes of methanol and water (6 point) NB 6 motion 0-3 water No vapor Quld 0.4 of water o.c of
