β¦ Synopsis
The multiple upcomer (Mu) extraction tray was specifically developed for aromatics extraction processes. Hydrodynamic and mass transfer experiments have been carried out w i t h n-butanollsuccinic acidwater as an experimental system in a MU tray extraction column of 0.1 m diameter. The dispersed phase hold-up, drop s u e and overall efticiency were measured and the hydrodynamic and mass transfer parameters were correlated. The flooding velocities and the overall efficiency predicted from the correlation for this column agreed well with the experimental data. On a spkifiquement mis au point un plateau d'extraction a colonnes montantes multiples (MU) pour les procedes d'extraction aromatiques. Des experiences hydrodynamiques et de transfert de matiere ont ete menees en utilisant le n- butanollacide succinique/eau comme systeme experimental dans une colonne d'extraction a plateaux MU de 0,l m de diametre, La retention de phase dispersee, la taille des gouttes et I'efficacite globale ont ete mesurees et on a correle les parametres hydrodynamiques et de transfert de matieres. Les vitesses d'engorgement et I'efficacite globale prbdites a partir de la correlation pour cette colonne concordent bien avec les donnees experimentales.
