Influence of gas flow rate on liquid distribution in trickle-beds using perforated plates as liquid distributors / Juan-David Llamas in Industrial & engineering chemistry research, Vol. 48 N°1 (Janvier 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°1 (Janvier 2009) . - p. 7-11 Titre : Influence of gas flow rate on liquid distribution in trickle-beds using perforated plates as liquid distributors Type de document : texte imprimé Auteurs : Juan-David Llamas, Editeur scientifique ; François Lesage, Editeur scientifique ; Gabriel Wild, Auteur Année de publication : 2009 Article en page(s) : p. 7-11 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Gas  flow  rate  liquid  distribution Résumé : Two wire mesh tomography devices and a liquid collector were used to study the influence of the gas flow rate on liquid distribution when fluids distribution on top of the reactor is ensured by a perforated plate. In opposition to most of the studies realized by other authors, conditions in which the gas has a negative impact in liquid distribution were evidenced. Indeed, the obtained results show that the influence of gas flow rate depends on the quality of the initial distribution, as the gas forces the liquid to “respect” the distribution imposed at the top of the reactor. Finally, a comparison between the two measuring techniques shows the limitations of the liquid collector and the improper conclusions to which its use could lead.
