S. and Man, Z.}, abstract = {A hybrid predictive model has been developed for accurate prediction of thermodynamics of carbon dioxide separation by aqueous alkanolamines. The model incorporates equation of state/excess Gibbs energy model into Kent{\^a}??Eisenberg approach to predict carbon dioxide{\^a}??alkanolamine{\^a}??water equilibria. The approach imparts theoretical corrections to Kent{\^a}??Eisenberg approach and significantly extends their range of application for monoethanolamine, diethanolamine, methyldiethanolamine, and 2-amino-2-methyl-1-propanol solutions. The proposed model suitably predicts thermodynamics of carbon dioxide separation, well beyond the regressed range of parameters. The results are in excellent agreement with experimental data for a wide range of process parameters and found superior to existing thermodynamic approaches. {\^A}{\copyright} 2016 Taylor \& Francis.}, issn = {01496395}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84987851786&doi=10.1080\%2f01496395.2016.1217241&partnerID=40&md5=f89bc8812cea5f40e3c66e780e9ff694} }
