“…Distillation is an expensive operation, both in terms of investment and operating costs (183), yet its ubiquity testifies to its effectiveness as a separation method, even for non-ideal and azeotropic mixtures. As a result of its prominence and expense, many contributions have been made to improve its design and operation (184). A review of early techniques can be found in (185,186).…”

This article first reviews recent developments in process synthesis and discusses some of the major challenges in the theory and practice in this area. Next, the article reviews key concepts in optimization-based conceptual design, namely superstructure representations, multilevel models, optimization methods, and modeling environments. A brief review of the synthesis of major subsystems and flowsheets is presented. Finally, the article closes with a critical assessment and future research challenges for the process synthesis area.

Currently, membrane gas separation systems enjoy widespread acceptance in industry As multistage systems are needed to achieve high recovery and high product purity simultaneously, many such configurations are possible. These designs rely on the process engineer's experience and therefore sub-optimal configurations are often the result. This paper proposes a systematic methodology for obtaining the optimal multistage membrane flowsheet and corresponding operating conditions. The new approach is applied to cross-flow membrane modules that separate CO 2 from CH 4 , for which the optimization of the proposed superstructure has been achieved via a MINLP model, with the gas processing cost as objective function. The novelty of this work resides in the large number of possible interconnections between each membrane module, the energy recovery from the high pressure outlet stream and allowing for non-isothermal conditions. The results presented in this work comprise the optimal flowsheet and operating conditions of two case studies.

“…The generation of logical relationships using Boolean or binary variables that can be included in a mathematical programming model, and that systematically include all the sequence of separation task that can be rearranged in N-1 distillation columns, was developed by Caballero and Grossmann in a set of papers -See for example, Caballero & Grossmann, (2014)-. As this model formulation does not rely on any specific column configuration, it is considered here as the starting point for generating intensified sequences.…”

In this work we present a methodology that transform insights from the conceptual design of intensified thermally coupled distillation in a set of logical expressions and mathematical models that can be integrated in a mathematical programming environment with the objective of systematically generate column sequences with a reduced number of actual columns (lower than N-1 columns, where N is the number of components). Some of the alternatives considered are Divided Wall Columns (DWC); Columns with vertical partitions, Kaibel like configurations, Elimination of transfer blocks, Extended DWC (including columns with vertical partitions) with external liquid transfer.The combination of all these alternatives provides a new rich space of alternatives, some of them not known before that should be taken into account in the design of distillation based separation systems. Some examples illustrate the procedure.
