Optimization of the design and operation of an extractive distillation system for the production of fuel grade ethanol using glycerol as entrainer / Pablo Garcia - Herreros in Industrial & engineering chemistry research, Vol. 50 N° 7 (Avril 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 7 (Avril 2011) . - pp. 3977-3985 Titre : Optimization of the design and operation of an extractive distillation system for the production of fuel grade ethanol using glycerol as entrainer Type de document : texte imprimé Auteurs : Pablo Garcia - Herreros, Auteur ; Jorge M. Gomez, Auteur Année de publication : 2011 Article en page(s) : pp. 3977-3985 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Fuel  Production  Extractive  distillation  Design  Optimization Résumé : The extractive distillation of ethanol using glycerol as entrainer is studied in order to find its optimal design and operating conditions. The optimization is formulated as a mixed integer nonlinear programming (MINLP) problem. The discrete variables determine the number of stages of the columns and their feed stage locations. The continuous variables include the variables of the equilibrium model and operating variables. The solution of the optimization problem is achieved through a two-level strategy that combines stochastic and deterministic algorithms. The result obtained establishes the process that maximizes an economic criterion for the industrial production of bioethanol satisfying the problem constraints.
