“…The combination of chemical reaction and thermodynamic separation inside a single unit represents one of the most promising methods of implementing process intensification (Schmidt-Traub and Górak, 2006;Stankiewicz, 2003). Compared to conventional reaction-separation sequences, such so-called integrated reactive separation processes offer the potential for large savings of capital, energy, and materials (Górak and Stankiewicz, 2011;van Gerven and Stankiewicz, 2009)).…”

Reactive distillation (RD) has already demonstrated its potential to significantly increase reactant conversion and the purity of the target product. Our work focuses on the application of RD to reaction systems that feature more than one main reaction. In such multiple-reaction systems, the application of RD would enhance not only the reactant conversion but also the selectivity of the target product. The potential of RD to improve the product selectivity of multiple-reaction systems has not yet been fully exploited because of a shortage of available comprehensive experimental and theoretical studies. In the present article, we want to theoretically identify the full potential of RD technology in multiple-reaction systems by performing a detailed optimisation study. An evolutionary algorithm was applied and the obtained results were compared with those of a conventional stirred tank reactor to quantify the potential of RD to improve the target product selectivity of multiple-reaction systems. The consecutive transesterification of dimethyl carbonate with ethanol to form ethyl methyl carbonate and diethyl carbonate was used as a case study.

The chemical process industry aims particularly at energy, capital expenditure and variable feedstock cost savings due to fierce global competition, the Kyoto Protocol and requirements for sustainable development.Increasingly conceptual process design methods are used in the industry to achieve these aims. They are used in:• existing processes to renew parts;• process re-designs based on existing feedstocks and catalysts;• innovative processes (new feed stocks, new catalysts, new process routes, new multifunctional equipment).This article is focused on the best industrial conceptual design practices applied for these application areas. To this end we have reviewed methods, which are used in the chemical process industry in the last 15 years. Capital, energy and variable cost savings are indicated for each method.Specific attention is paid to:• functional integration to multi-functional equipment;• heuristic based selection of unit operations and recycle structure;• superstructure based design optimisation with mixed-integer-non-linear programming (MINLP).
