We present a methodology to estimate the maximum recovery of each component in an azeotropic multicomponent mixture processed at a batch distillation column. Based in the most recent advances in the field of separation feasibility we have adapted an algorithm to predict all the distillation regions for the multicomponent mixture with their corresponding natural and distillation boundaries. The results of the maximum separation problem together with those corresponding to conceptual dynamic runs are used to illustrate several important issues related to the synthesis and design of highly non-ideal azeotropic mixtures.
