Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 50 N° 10 (Mai 2011) . - pp. 6287-6296 Titre : Shortcut design of fully thermally coupled distillation systems with postfractionator Type de document : texte imprimé Auteurs : Lorena E. Ruiz-Marin, Auteur ; Nelly Ramirez-Corona, Auteur ; Angel Castro-Aguero, Auteur Année de publication : 2011 Article en page(s) : pp. 6287-6296 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Distillation Design Résumé : A modification to the fully thermally coupled distillation system, or Petlyuk column, in which a postfractionator is added has recently been considered. The modified structure incorporates the postfractionator aiming for a better match in the composition of the interlinking stages of the Petlyuk column. In this paper we present a design method for the modified thermally coupled system with postfractionator. A shortcut method is used to provide the minimum reflux conditions of the system, and the boundary value method is used to complete the design task. The effectiveness of the design method is shown through the application to several case studies. The effect of the postfractionator on the performance of the Petlyuk system is also analyzed.
