Experimental studies to the effect of interactions between diffusion fluxes in ternary distillation of the methanol-2-propanol-water system are made by a vertical flat plate wetted-wall column under total reflux conditions for wide ranges of vapor flow rates and liquid concentrations.
Observed vapor-phase diffusion fluxes are compared with the results of numerical analysis for ternary mass transfer in the laminar boundary layer with surface mass injection or suction. The effects of partial condensation of mixed vapors and of interactions between diffusion fluxes are examined with reference to the laminar boundary layer theory for ternary mass systems. A correlation for the vapor-phase diffusion fluxes in ternary distillation is proposed by considering the effect of interactions between diffusion fluxes under high mass flux conditions.
