Optimizing control of CSTR/distillation column processes with one material recycle / Hiroya Seki ; Naka Yuji in Industrial & engineering chemistry research, Vol. 47 n°22 (Novembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°22 (Novembre 2008) . - p. 8741–8753 Titre : Optimizing control of CSTR/distillation column processes with one material recycle Type de document : texte imprimé Auteurs : Hiroya Seki, Auteur ; Naka Yuji, Auteur Année de publication : 2008 Article en page(s) : p. 8741–8753 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : CSTR/Distillation Résumé : Control system design for recycle processes that are composed of a continuous stirred tank reactor (CSTR) and a distillation column is discussed. It is shown that the reflux ratio control, which has been known to serve as a self-optimizing control for the process with the elementary chemistry A → B, can be also applied to processes with more-general types of chemistry that involves side reactions. Using the self-optimizing control as the basis, control systems that seek economically optimal operations are hierarchically constructed for example processes with different types of process chemistry. Particularly, for a process that exhibits tradeoff between product yield and separation cost, a linear model predictive controller design example is given with simulation results.
