Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 15 (Août 2010) . - pp 7085–7092 Titre : Phase behavior modeling of alkyl−amine+water mixtures and prediction of alkane solubilities in alkanolamine aqueous solutions with group contribution with association equation of state Type de document : texte imprimé Auteurs : Francisco A. Sanchez, Auteur ; Ticiana M. Soria, Auteur ; Selva Pereda, Auteur Année de publication : 2010 Article en page(s) : pp 7085–7092 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Alkyl amine Water Alkane solubilities Aqueous solutions. Résumé : Precise knowledge of phase behavior of natural gas+aqueous alkanolamine solutions is of interest to design and optimize amine absorption units. In this work, we extend a group contribution with association equation of state to the modeling of phase behavior of mixtures containing water, alkanolamine, and light hydrocarbons (HC). The model parameters were estimated on the basis of binary vapor−liquid equilibrium and liquid−liquid equilibrium data of the following binary systems: HC + amines, HC + alcohol, water + amine, water + alcohol. The group contribution approach allows the use of an extended databank of experimental data which gives a solid foundation for predicting hydrocarbon solubility in aqueous alkanolamine solutions.
