Abstract

In order to evaluate the behavior of extractive distillation columns efficiency was used the correlation developed by Barros & Wolf, which considers the mass and heat transfer parameters, based on the physical and thermal characteristic of ideal and non-ideal liquid mixtures. The results obtained from Barros & Wolf correlation efficiency were compared with the experimental data obtained by Meirelles. For all cases studied, the solvent used to separate each mixture, reflect on the efficiency values in extractive distillation column. Those factors are more strongly when the interaction between the liquid and vapor phase in the column promote the turbulence, factor predominant on mass and heat transference. The correlation used here shows good approximation when the data from this correlation were compared with that from real profile data obtained by Meirelles, for extractive distillation column. The precision of this correlation is due the mass and heat phenomenon are involved in real process and the behavior efficiency along of distillation column is similar that described in the literature. For this, due the high complexity associated with carried out experiment in laboratory, the correlation used here can be explore to evaluate the profile of extractive distillation operations.
