Design of hybrid distillation-vapor membrane separation systems / Jose A. Caballero in Industrial & engineering chemistry research, Vol. 48 N° 20 (Octobre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 20 (Octobre 2009) . - pp. 9151–9162 Titre : Design of hybrid distillation-vapor membrane separation systems Type de document : texte imprimé Auteurs : Jose A. Caballero, Auteur ; Ignacio E. Grossmann, Auteur ; Majid Keyvani, Auteur Année de publication : 2010 Article en page(s) : pp. 9151–9162 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Hybrid  separation  system  Distillation  column  separation  Parallel  membrane  separation  Two-stage  approach Résumé : Currently the separation of olefins (ethylene, propylene) from (ethane, propane) on a commercial scale is performed almost exclusively by cryogenic distillation in petrochemical industries. Since this technology is highly energy intensive, there is a strong economic incentive to explore alternative separation technologies with lower energy consumption. In this work, using the separation of ethylene and ethane as a representative case, a mathematical programming approach is proposed to optimize and retrofit a hybrid separation system consisting of a distillation column and a parallel membrane separation unit. A two-stage approach is used. First, a shortcut model is introduced that allows determining whether the hybrid system could be of interest and the order of magnitude of the energy savings that can be expected. Second, a superstructure optimization approach is proposed that uses rigorous models for both the column and the membrane using a process simulator and state of the art MINLP solvers. The results presented in the case study show that significant savings in total costs and energy (up to 30%) can be obtained with the hybrid system.

Economic and environmental assessment of alternatives to the extraction of acetic acid from water / Norberto Garcia in Industrial & engineering chemistry research, Vol. 50 N° 18 (Septembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 18 (Septembre 2011) . - pp. 10717-10729 Titre : Economic and environmental assessment of alternatives to the extraction of acetic acid from water Type de document : texte imprimé Auteurs : Norberto Garcia, Auteur ; Jose A. Caballero, Auteur Année de publication : 2011 Article en page(s) : pp. 10717-10729 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Environment  impact Résumé : A comparison was made between conventional binary distillation and four feasible alternatives flowsheets to separate acetic acid from water attending to both economic and environmental criteria. All extraction steps use diethyl ether as an extractant. Our goals were, first, to estimate the economic and environmental incentives for each of the alternatives proposed in order to understand the trade-offs associated with each system and second, to show how, in some flowsheets, it is possible to rigorously decompose the system and perform detailed optimization without the necessity of simultaneous optimization of all the equipment implied in the flowsheet. To carry out the economic evaluation, two simple criteria were used: Economic Potential and Total Annual Cost These parameters were chosen because they can be used at various stages in the chemical plant design without the necessity of a complete picture of the industrial process. The environmental impacts are measured through the Ecoindicator-99 methodology, which reflects the advances in the damaged-oriented methodology recently developed for Life Cycle Assessment. For each of the alternatives, detailed optimization was performed to determine the Pareto's individual curves using the ε-constraint method. With the individual Pareto curves, it is also possible to obtain the compound Pareto's curve, and to then superimpose the individual Pareto's curves associated with the five alternatives to identify the trade-offs of this multiobjective optimization and ultimately determine the best alternatives, and even their optimum operational conditions.
