Effects of CO2 on a High Performance Hollow-Fiber Membrane for Natural Gas Purification / Imona C. Omole in Industrial & engineering chemistry research, Vol. 49 N° 10 (Mai 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 10 (Mai 2010) . - pp. 4887–4896 Titre : Effects of CO2 on a High Performance Hollow-Fiber Membrane for Natural Gas Purification Type de document : texte imprimé Auteurs : Imona C. Omole, Auteur ; Ryan T. Adams, Auteur ; Stephen J. Miller, Auteur Année de publication : 2010 Article en page(s) : pp. 4887–4896 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Natural  Gas  Fiber Résumé : A 6FDA-based, cross-linkable polyimide was characterized in the form of a defect-free asymmetric hollow-fiber membrane. The novel membrane was cross-linked at various temperatures and tested for natural gas purification in the presence of high CO2 partial pressures. The cross-linked membrane material shows high intrinsic separation performance for CO2 and CH4 (selectivity 49, CO2 permeability 161 barrer, with a feed at 65 psia, 35 °C, and 10% CO2). Cross-linked asymmetric hollow-fiber membranes made from the material show good resistance to CO2-induced plasticization. Carbon dioxide partial pressures as high as 400 psia were employed, and the membrane was shown to be promisingly stable under these aggressive conditions. The performance of the membrane was also analyzed using the dual-mode sorption/transport model.
