Separation of an acetone−methanol mixture by pressure-swing batch distillation in a double-column system with and without thermal integration / Gabor Modla in Industrial & engineering chemistry research, Vol. 49 N° 8 (Avril 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 8 (Avril 2010) . - pp. 3785–3793 Titre : Separation of an acetone−methanol mixture by pressure-swing batch distillation in a double-column system with and without thermal integration Type de document : texte imprimé Auteurs : Gabor Modla, Auteur ; Peter Lang, Auteur Année de publication : 2010 Article en page(s) : pp. 3785–3793 Langues : Anglais (eng) Mots-clés : Acetone−Methanol  Mixture  Batch  Distillation  Thermal  Integration Résumé : Pressure-swing batch distillation in a double-column system is suggested for the separation of an acetone−methanol pressure-sensitive azeotropic mixture. The studied column configuration is the double-column batch stripper in open mode. We investigated this separation by rigorous simulation using a professional dynamic flow-sheet simulator. The influence of the most important operational parameters is studied. The energy demand of the separation is converted to carbon dioxide emission. The two columns can be thermally integrated to save energy. The effectiveness of thermal coupling is also investigated at different pressure gaps.

Separation of a chloroform–acetone–toluene mixture by pressure-swing batch distillation in different column configurations / Gabor Modla in Industrial & engineering chemistry research, Vol. 50 N° 13 (Juillet 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 13 (Juillet 2011) . - pp. 8204-8215 Titre : Separation of a chloroform–acetone–toluene mixture by pressure-swing batch distillation in different column configurations Type de document : texte imprimé Auteurs : Gabor Modla, Auteur Année de publication : 2011 Article en page(s) : pp. 8204-8215 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Distillation  Batchwise Résumé : In this paper, a new, triple-column configuration application is introduced to separate ternary mixtures by pressure-swing batch distillation. This study investigates the separation of a chloroform-acetone-toluene ternary mixture in different column configurations (a combination of the batch stripper and the double-column batch rectifier, the double-column batch rectifier, and the triple-column configuration) by a feasibility study and by rigorous simulation and compares these processes at two different charge compositions by its overall specific energy consumption. The influences of the most important operational parameters are studied for all processes, and the performances of the column configurations are compared. On the basis of the results, we state that the triple-column configuration is more efficient than the other column configurations investigated.
