Simulation and optimal design of electrodeionization process / Anjushri S. Kurup 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. 9268–9277 Titre : Simulation and optimal design of electrodeionization process : separation of multicomponent electrolyte solution Type de document : texte imprimé Auteurs : Anjushri S. Kurup, Auteur ; Thang Ho, Auteur ; Jamie A. Hestekin, Auteur Année de publication : 2010 Article en page(s) : pp. 9268–9277 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Electrodeionization  technology  Ultrapure  water  Electrolyte  solutions Résumé : Electrodeionization (EDI) technology combines the operation principle of both ion exchange and electrodialysis in one single unit and overcomes the disadvantages of either unit. This technology has been widely used in the production of ultrapure water due to its better performance and economical operation at low feed concentrations. As a result, there have been several studies that deal with application of this technology for the removal of ions from water. However, except for a few studies, most of the reported works deal with the experimental study of EDI. This study deals with the development of a mathematical model for deionization of electrolyte solutions containing more than one ion and ions that are multivalent in nature. The model validity is verified by comparing the results with a few experimental observations. This is followed by a sensitivity study of the EDI unit to explore the effect of various operating and system parameters on the ion removing ability of the EDI unit. Consequently, a systematic optimization exercise that can simultaneously handle more than one objective for superior system performance of the experimental unit is demonstrated. Due to the optimization study, it is shown that many times EDI is not operated at optimized conditions and decreasing the flow rate, among other variables, might have a significant effect on system performance.
