Abstract: In "Influence of Mass Transfer in Distillation: Residue Curves and Total Reflux" (Dec. 2004), Taylor et al. presented some comments on the article entitled "On the dynamics of simple batch distillation processes" (Chemical Engineering and Processing) by J.M.F. Silva et al. Taylor et al. agreed with most of the assumptions, but considered the change of the total vapor pressure across the film as rather unusual. They argued that this difference leads to bulk fluid motion across the film, and that it is "standard practice" in mass-transfer modeling to assume the transfer to be isobaric. According to Silva, this is misleading for simple batch distillation because there is a bulk fluid motion across the film. The batch distillation process is a differential distillation, where back-diffusion is not allowed to occur. Taylor et al. affirmed that the calculations performed in the article are wrong. For Silva, the work is consistent and it is correct, presenting a more adequate model for the simple batch distillation processes.
