P 2 ) An aqueous solution of methanol is being separated by distillation in column. Methanol ( A ) , which is the more volatile
P An aqueous solution of methanol is being separated by distillation in column. Methanol A which is the more volatile component, moves from the liquid phase to the vapour phase while water B the less volatile component, gets transported in the opposite direction. At a section of the column, the vapour phase contains mole fraction methanol and the liquid has mole fraction of it The temperature is and the total pressure is essentially atmospheric. The diffusional resistance offered is equivalent to that of a 'stagnant' vapour film of thickness. If the latent heat of vaporization of methanol is kca and that of water is kca at the given temperature, calculate the flux of methanol and that of water vapour. Given: if the mole fraction of methanol in the solution is its mole fraction in the equilibrium vapour would be The vapourphase mutual diffusivity,

transported in the opposite direction. At a section of the column, the vapour
phase contains mole fraction methanol and the liquid has mole
