Model building methodology for multiphase reaction systems / Rameshwar Hiwale in Industrial & engineering chemistry research, Vol. 50 N° 17 (Septembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 17 (Septembre 2011) . - pp. 10148-10157 Titre : Model building methodology for multiphase reaction systems Type de document : texte imprimé Auteurs : Rameshwar Hiwale, Auteur ; Sungwon Hwang, Auteur ; Robin Smith, Auteur Année de publication : 2011 Article en page(s) : pp. 10148-10157 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Modeling Résumé : A new approach to reactor model building for two-phase absorption processes is developed by considering simultaneously mass and heat transfer phenomena, and chemical reaction mechanism and kinetics. In particular, the interaction of mass and heat transfer with chemical reaction over the reactor design is considered to improve the accuracy of the simulation results. A novel methodology is applied to identify suitable reaction mechanisms and kinetics based on limited experimental data. This methodology allows the engineer to develop feasible reaction mechanisms in a systematic approach. Importantly, the required scope for any further lab experiments is identified, especially when the modeling needs further clarification for the reaction kinetics or mechanisms. In this way, a more robust reactor design can be achieved by making full use of experimental information, saving unnecessary laboratory and pilot plant experiments. For a case study, chlorine absorption to oleic acid is applied to the modeling of a laminar jet absorber.

Model building methodology for multiphase reaction systems — modeling of CO2 absorption in monoethanolamine for laminar jet absorbers and packing beds / Rameshwar Hiwale in Industrial & engineering chemistry research, Vol. 51 N° 11 (Mars 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 11 (Mars 2012) . - pp. 4328–4346 Titre : Model building methodology for multiphase reaction systems — modeling of CO2 absorption in monoethanolamine for laminar jet absorbers and packing beds Type de document : texte imprimé Auteurs : Rameshwar Hiwale, Auteur ; Sungwon Hwang, Auteur ; Robin Smith, Auteur Année de publication : 2012 Article en page(s) : pp. 4328–4346 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Chemical  reactions  Absorption  processes Résumé : This research has focused on a new methodology to develop a rigorous reactor model for gas–liquid chemical reactions in absorption processes. This involves simultaneous chemical reaction and mass transfer between two phases. In particular, all feasible chemical reaction mechanisms and kinetics are considered for the modeling to improve the accuracy of the simulation results. Detailed mathematical modeling is developed to identify physical properties of the key components. For a reactor design, a packed bed reactor has been developed with two different types of modeling approaches. The results of two separate models are compared with the laboratory experimental data. For a case study, CO2 absorption to monoethanolamine (MEA) solution is used based on a wide range of experimental data from both laminar jet absorber and packed bed column.
