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 / Francisco A. Sanchez in Industrial & engineering chemistry research, Vol. 49 N° 15 (Août 2010) 

Public ISBD [article]  in Industrial & 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.

Phase behavior modeling of alkyl amine + hydrocarbon and alkyl amine + alcohol systems using a group contribution associating equation of state / Francisco A. Sanchez in Industrial & engineering chemistry research, Vol. 48 N° 16 (Août 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 16 (Août 2009) . - pp. 7705–7712 Titre : Phase behavior modeling of alkyl amine + hydrocarbon and alkyl amine + alcohol systems using a group contribution associating equation of state Type de document : texte imprimé Auteurs : Francisco A. Sanchez, Auteur ; Amir H. Mohammadi, Auteur ; Alfonsina Andreatta, Auteur Année de publication : 2009 Article en page(s) : pp. 7705–7712 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Alkyl  amine  +  hydrocarbon  systemAlkyl  amine  +  alcohol  system  State  namely  GCA-EoS Résumé : In this work, a group contribution-associating equation of state namely GCA-EoS, is extended to model the phase behavior of alkyl amine + hydrocarbon and alkyl amine + alcohol systems while considering the association of functional groups. A generalized routine has been implemented to quantify the association effects through functional groups with associating sites. The predictions of the model are found in good agreement with experimental data reported in the literature. The model parameters were estimated in the temperature range 218−428 K and pressures up to 735 kPa.
