Gas holdup in gas — liquid stirred tanks / Sean G. Mueller in Industrial & engineering chemistry research, Vol. 49 N° 21 (Novembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 21 (Novembre 2010) . - pp. 10744-10750 Titre : Gas holdup in gas — liquid stirred tanks Type de document : texte imprimé Auteurs : Sean G. Mueller, Auteur ; Milorad P. Dudukovic, Auteur Année de publication : 2011 Article en page(s) : pp. 10744-10750 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Stirred  vessel  Hydrodynamics  Gas  holdup Résumé : A single-point optical probe is developed that can accurately obtain local gas holdup in a gas-liquid stirred tank across a wide range of operating pressures, temperatures, and fluids. It is found that the probe orientation to the flow in a stirred tank can cause underestimations in gas holdup if only a single probe orientation is used. The probe is also able to capture the complex flow pattern in the vessel. This allows improved understanding of optical probes and stirred tanks and generation of data at elevated pressure and temperature conditions needed for development of new fundamental models.
