In this work we present an overview of the main advances in column sequence optimization in zeotropic systems, ranging from systems using only conventional columns, each with a condenser and a reboiler, to fully thermally coupled systems with a single reboiler and a single condenser in the entire sequence. We also review the rigorous design of distillation columns, or column sequences. In all the cases we focus on mathematical programming approaches.

“…To solve the problem, they used the so called successive relaxed MINLP (SR-MINLP) proposed by Kraemer et al (2007), which reformulate the MINLP or GDP problems as pure continuous problems with tailored big-M constraints, where all discrete decisions are represented by continuous variables. The discrete decisions are enforced by non-convex constraints that force the continuous variables to take discrete values A c c e p t e d M a n u s c r i p t Even with all these difficulties, complex problems have been successfully solved, including reactive distillation (Ciric & Gu, 1994;Jackson & Grossmann, 2001); azeotropic sequences (Mariana Barttfeld et al, 2004;Bauer & Stichlmair, 1996, Thermally coupled distillation sequences (Dunnebier & Pantelides, 1999) or hybrid membrane/distillation systems (Kookos, 2003) among others.…”

We take advantage of the best of algebraic models and process simulators. AbstractIn this paper, we propose a novel algorithm for the rigorous design of distillation columns that integrates a process simulator in a generalized disjunctive programming formulation. The optimal distillation column, or column sequence, is obtained by selecting, for each column section, among a set of column sections with different number of theoretical trays. The selection of thermodynamic models, properties estimation etc., are all in the simulation environment. All the numerical issues related to the convergence of distillation columns (or column sections) are also maintained in the simulation environment. The model is formulated as a Generalized Disjunctive Programming (GDP) problem and solved using the logic based outer approximation algorithm without MINLP reformulation. Some examples involving from a single column to thermally coupled sequence or extractive distillation shows the performance of the new algorithm.

“…Different configurations of a superstructure can result in faster solution times as well as a reduction in the complexity of the formulation. For instance, Bauer & Stichlmair (1996) stated that previous superstructures for distillation separation sequences did not take into account direct column coupling, non ideal and azeotropic mixtures. Therefore, the authors developed a superstructure where coupled columns and complex separation schemes could be handled as well as handling zeotropic and homogeneous azeotropic mixtures.…”
