Abstract
Experimental studies on vapor-phase mass and sensible heat fluxes in ternary distillation of the acetone-methanol-ethanol system were made by a vertical flat-plate wetted-wall column under total reflux conditions.
Observed vapor-phase diffusion fluxes of each component were found to be proportional to their concentration driving-forces, whereas observed vapor-phase mass fluxes were not. Dimensionless vapor-phase diffusion fluxes and sensible heat fluxes showed good agreement with laminar boundary layer theory with mass injection and suction.
Simulation of the distillation path for ternary distillation by a vertical flat-plate wetted-wall column were made, and it showed good agreement with the observed distillation paths.
