“…The model was originally developed by and was successfully used for the simulation of different RD processes (Hoffmann et al, 2004;Kenig et al, 2001;Kloeker et al, 2005). We have recently published an article, in which the model validation for the homogeneously catalysed transesterification of DMC with EtOH is comprehensively described (Keller and Górak, 2013).…”

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.

a b s t r a c tSolubility, critical states and liquid-liquid equilibrium (LLE) data for the quaternary system acetic acid-ethanol-ethyl acetate-water and for the ternary subsystems acetic acid-ethyl acetate-water and ethanol-ethyl acetate-water were studied at 303.15 K and 313.15 K and atmospheric pressure. Binodal surfaces, binodal curves, tie-lines and compositions of critical points were determined. In order to construct the binodal surfaces and critical curves of the quaternary system, five quaternary sectional planes with several different ratios of concentration of acetic acid to ethanol were studied. Experimental LLE data were compared with the values calculated by UNIFAC and NRTL models, and it was found that the experimental and calculated data are in good agreement.

“…There is a rich literature on catalytic and reactive distillation and several process applications. Nevertheless, a large gap remains between academic analysis (Sundmacher et al, 1994;Thiel et al, 1997;Bessling et al, 1998;Lee and Dudukovic, 1998;Xu and Dudukovic, 1999;Venimadhavan et al, 1999;Chen et al, 2000Chen et al, , 2002Kenig et al, 2001;Stitt, 2002;Sundmacher and Kienle, 2003) of the combined reaction-distillation process and practical implementations (Smith and Arganbright, 2000;Hearn et al, 2002;Smith et al, 2003;Smith and Adams, 2006). There is resistance to replacing depreciated working equipment with new, more improved installations.…”

The importance of reaction engineering in generating a myriad of products on which developed societies depend is outlined. The challenges of a political, economic, and technical nature that need to be addressed in rendering conversion of raw materials into desired products that are more environmentally friendly and sustainable are briefly discussed. It is shown that multiphase reactors are prevalent in all applications, and improvements in the reactor material and energy efficiencies lead to more environmentally benign processes. This requires, in addition to the selection of green process chemistry, systematic implementation of the multi-scale reaction engineering methodology to accomplish proper reactor type selection and scaleup for commercial applications. It is also illustrated that recent innovations in multiphase reaction engineering basically utilize two key concepts: process intensification (e.g., enhancement in mass and heat transfer rates) and simultaneous reaction and separation. Examples of these are discussed, such as micro-reactors, reactive distillation, etc. It is also shown that commercialization of bench-scale discoveries requires either scaleup in parallel or vertical scaleup. New tools for visualization of opaque multiphase flows and development of appropriate rational phenomenological multiphase reactor models for scaleup and design are also briefly discussed.
