Abstract

The feasibility of the separation of minimum boiling binary homoazeotrope using a batch heterogeneous extractive distillation was studied. The applied entrainer formed a binary heterogeneous azeotrope with the less volatile component of the original azeotrope. The studied mixture was acetonitrile and water, with butyl acetate as entrainer. The composition constraint was the minimum distillate purity. This assigned a tie line and a destination region in the top of the column. According to the feed position profile, maps were calculated to determine the feasible region and to examine the effect of the operational parameters. If the effect of the operational parameters are well-known, the separation sequence can be determined and a verification can be performed for the process. If the entrainer is fed to the reboiler, the separation is feasible but practically useless, because enormous amount of entrainer is needed to be premixed into the reboiler. If the entrainer is fed into the top of the column, the separation is feasible, but there is a maximum entrainer flowrate limit due to the distillate purity. The results were validated by ProsimBatch simulator. This is an abstract of a paper presented at the 7th World Congress of Chemical Engineering (Glasgow, Scotland 7/10-14/2005).
