Feasibility of batch reactive distillation

Abstract:
This article addresses gaining design insights into possible product cuts in batch reactive distillation columns from the geometrical analysis. For binary reactive systems, a batch rectifier allows us to circumvent a maximum boiling azeotrope while a batch stripper can eliminate a minimum boiling one. However this design insight cannot be extended into multicomponent systems such as ternary and quaternary reactive systems. By visualizing reaction equilibrium manifolds and distillation boundaries in the composition space, we can identify possible product cuts in various batch reactive configurations. More efforts will be made to derive a systematic method for the evaluation of the feasibility of various batch reactive distillation columns.
