Prediction of H2S and CO2 solubilities in aqueous triethanolamine solutions using a simple model of kent – eisenberg type / Wael A. Fouad in Industrial & engineering chemistry research, Vol. 51 N° 18 (Mai 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 18 (Mai 2012) . - pp. 6591-6597 Titre : Prediction of H2S and CO2 solubilities in aqueous triethanolamine solutions using a simple model of kent – eisenberg type Type de document : texte imprimé Auteurs : Wael A. Fouad, Auteur ; Abdallah S. Berrouk, Auteur Année de publication : 2012 Article en page(s) : pp. 6591-6597 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Modeling  Solubility  Carbon  dioxide  Hydrogen  sulfides  Prediction Résumé : Absorption of acid gases (H2S and CO2) by aqueous solutions of alkanolamines is the most commonly used process in the gas treatment industry. Recent process investigations on the use of triethanolamine (TEA) show its potential to render the gas sweetening operation more energy efficient in particular when mixed to methyldiethanolamine (MDEA). This paper presents a simple model of Kent-Eisenberg type that computes the dissociation of the protonated triethanolamine (TEA) equilibrium constant The model can be used to correlate mixed acid gases solubility data over 2, 3.5, and 5 M of aqueous TEA solutions at 50, 75, and 100 °C. Results for the new model shows high fitting percentage errors for both acid gases; however, the model was able to predict H2S and CO2 partial pressures accurately for another set of unfitted data. Despite the highly fitted percentage errors, the model was used as an initial guess for a different Kent-Eisenberg model which resulted into a significantly lower percentage error at 50°C.
