In this contribution, a sequential and hierarchical approach for the feasibility analysis and the preliminary design of reactive distillation columns is extended to systems involving vapour phase chemical reaction and is successfully applied to the HI vapour phase decomposition to produce H2.The complex phase and physico chemical behaviour of the quaternary HI-H2-I2-H2O system is represented by the Neumann's thermodynamic model and instantaneous vapour phase chemical equilibrium is assumed.Then, from minimal information concerning the physicochemical properties of the system, three successive steps lead to the design of the unit and the specification of its operating conditions: the feasibility analysis, the synthesis and the design step. First, the analysis of reactive condensation curve map method (rCCM), assuming infinite internal liquid and vapour flow rate and infinite reflux ratio, is used to assess the feasibility of the process. It determines the column structure and estimates the attainable compositions. These results are used as inputs data for the synthesis step. Based on the boundary value 2 design method (BVD), considering finite internal liquid and vapour flow rate and finite reflux ratio while neglecting all thermal effects and assuming a constant heat of vaporisation, the synthesis step provides more precise information about the process configuration (minimum reflux ratio, number of theoretical stages, localisation and number of reactive plates, position of the feed plate). Finally, the BVD method results are used to initialise rigorous simulations, based on an equilibrium stage model with energy balance, to estimate the reflux ratio taking into account thermal effect on the process.

“…The optimisation of RD processes is usually a mixed-integer nonlinear programming (MINLP) problem, because of the nonlinear coupling of chemical reaction, transport phenomena and phase equilibria and the presence of discrete variables (Almeida-Rivera et al, 2004;Doherty and Malone, 2001). The latter are commonly used to decide the existence and/or type of a stage, e.g., feed stage, nonreactive or reactive stage (Gangadwala and Kienle, 2007).…”

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 catalyst selection, the reaction volume provided by column internals, and the position of the feeds are the major design parameters for reactive distillation processes. Almeida-Rivera et al classified the available methods for designing reactive distillation processes into graphical, heuristic, and optimization methods and discussed them in a comprehensive manner [39].…”
