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.

“…Keller et al experimentally demonstrated that reactive distillation is able to overcome the limitation of target product selectivity in a multiple-reaction system, regardless of whether it is formed as an intermediate product or at the end of consecutive reactions [129]. Both of these cases were treated in the example of the transesterification of dimethyl carbonate with ethanol.…”

“…The minimization of the least squares sum is done under the restriction that the mass-and component balances are fulfilled. For a reactive system the reaction stoichiometry must be provided in the latter case [7,8]. Additionally, the user has the possibility to define further restrictions, e.g., purity specifications on product streams.…”

The development of chemical processes is based on both experiments and process simulations. Data evaluation and reconciliation, model development and validation, and design of experiments are essential steps in this procedure. The different tools and approaches available are usually not supported in an integrated way in the process developer's workflow. Therefore, a framework for process design was created and integrated in a tool box which supports process design comprehensively. It contains methods for data selection and reconciliation, sensitivity analysis, model validation and model adjustment.
