Abstract
This paper deals with the feasibility analysis of batch extractive distillation taking into account the effect of the univolatility lines ai,j = 1 and the shape of residue curves for ternary mixtures involving two binary azeotropes. A general feasibility criterion previously established for ternary mixtures only including one azeotrope is now extended to Serafimov’s classification diagrams: 2.0-1, 2.0-2a, 2.0-2b and 2.0-2c. Application of the feasibility criterion hints at which component goes up or down using a rectifying or stripping column. Preliminary feasibility results are verified by computing the map of extractive liquid profiles using a simplified modelling. Examples including batch rectifier are also corroborated by rigorous simulation using ProSim Batch.
