Modeling and simulation of a downer-Type HS-FCC unit / Abdullah A. Shaikh in Industrial & engineering chemistry research, Vol. 47 N° 23 (Décembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N° 23 (Décembre 2008) . - p. 9018–9024 Titre : Modeling and simulation of a downer-Type HS-FCC unit Type de document : texte imprimé Auteurs : Abdullah A. Shaikh, Auteur ; Eid M. Al-Mutairi, Auteur ; Takashi Ino, Auteur Année de publication : 2009 Article en page(s) : p. 9018–9024 Note générale : Engineering Chemistry Langues : Anglais (eng) Mots-clés : Modeling  and  Simulation  of  a  Downer  --  Type  HS-FCC  Unit Résumé : Mathematical models and simulations of an integrated downer−regenerator FCC unit are presented. The models describe the steady-state nonisothermal behavior of the interdependent heavy oil cracking downflow reactor and catalyst regeneration fluidized-bed reactor. The models are rooted in four-lump cracking reaction kinetics and complete combustion kinetics for the regenerator reactions. Simulations results for the downer-type unit are partially validated against data collected in a 0.1−0.3 b/day pilot plant that was operated in the high-severity mode. The results are fairly reasonable especially in regard to predicting the performance of the cracking reactor.
