Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 47 N°17 (Septembre 2008) . - p. 6685–6697 Titre : Coupling exothermic and endothermic reactions in plug-flow reactor-separation-recycle systems Type de document : texte imprimé Auteurs : Pietro Altimari, Auteur ; Costin Sorin Bildea, Auteur Année de publication : 2008 Article en page(s) : p. 6685–6697 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Plug-flow reactor-separation-recycle systems Exothermic reaction Endothermic Résumé : The nonlinear behavior of plug-flow reactor−separation−recycle systems, where the endothermic first-order reaction A → R + Q and the exothermic second-order reaction B + Q → P simultaneously take place, is investigated. As the physical properties of the species involved vary, possible flowsheets are identified and feasible control strategies are suggested. Bifurcation analysis of the reactor−separation−recycle system is performed by choosing set-point variables as bifurcation parameters. Steady state multiplicity is invariably detected leading to complex behavior. Implications on plantwide control are thoroughly discussed and guidelines are provided which enable to select values of set-point variables in a way that guarantees safe operation.
