Plantwide design of ideal reactive distillation processes with thermal coupling / Wang, San-Jang in Industrial & engineering chemistry research, Vol. 49 N° 7 (Avril 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 7 (Avril 2010) . - pp. 3262–3274 Titre : Plantwide design of ideal reactive distillation processes with thermal coupling Type de document : texte imprimé Auteurs : Wang, San-Jang, Auteur ; Hao-Yeh Lee, Auteur ; Jui-Hung Ho, Auteur Année de publication : 2010 Article en page(s) : pp. 3262–3274 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Plantwide  Design  Distillation  Thermal  Coupling Résumé : Process intensification is aimed to integrate different processes in design to reduce energy consumption and capital investment, as well as to achieve environmental and safety benefits. Reactive distillation and thermally coupled distillation are examples of such process intensification. In this study, the performance of thermally coupled reactive distillation, a technology combining reactive distillation and thermally coupled distillation, is investigated for ideal quaternary reaction systems with different rankings of relative volatility. Possible configurations of thermally coupled reactive distillation are designed for systems of types IR, IIR, and IIIR with the excess design and type IIP with the stoichiometric design. Reactive distillation with thermal coupling is demonstrated to provide better energy efficiency than conventional reactive distillation. The remixing phenomenon associated with thermodynamic inefficiency in conventional distillation sequences can be reduced or eliminated by implementing thermal coupling between columns.
