Modular representation synthesis framework for homogeneous azeotropic separation

The synthesis and design of separation systems for nonideal azeotropic mixtures traditionally utilize graphical methods, focusing on separation feasibility within a sequential design framework. Once promising systems have been identified, sequencing and design are optimized in a second stage, limited by the separation feasibility region defined in the first stage. A generalized modular representation proposed for the synthesis of nonideal separations can simultaneously explore entrainer and sequencing alternatives. A multipurpose mass/heat exchange module, introduced in earlier work, is employed to investigate separation units and structures as mass‐ and heat‐exchange possibilities. Process units, separation sequences, and entrainers that aid the separation are examined within one separation problem rather than in a sequential manner. Promising separation schemes can be further considered for detailed design optimization.
