Abstract

The Basket Impeller Column combines the mass transfer advantages of a spinning basket reactor with the practicality of a dual flow tray column to achieve controllable liquid holdup, as well as a potential solution to many of the problems plaguing current catalytic distillation internals. Sieve plate design, impeller size and speed, along with water and air, flow rates were explored in order to establish a feasible design. An optimal set of specifications was determined via statistical evaluation. Additional experiments were then conducted to obtain correlations for liquid holdup, gas holdup, froth height, pressure drop and power in terms of the significant hydraulic variables.

Abstract

La colonne à turbine à panier combine les avantages de transfert de matière d'un réacteur à panier tournant et le côté pratique d'une colonne à plateau à double écoulement, ce qui permet de contrôler la rétention de liquide et de fournir ainsi une solution possible aux nombreux problèmes affectant les internes courants de distillation catalytique. La conception des plateaux perforés à déversoir, la taille et la vitesse des turbines ainsi que les débits d'air et d'eau ont été explorés afin d'obtenir une configuration réalisable. On a déterminé un ensemble optimal de spécifications par l'évaluation statistique et on a mené d'autres expériences pour obtenir des corrélations pour la rétention de liquide, la rétention de gaz, la hauteur de mousse, la perte de charge et l'énergie en fonction des variables hydrauliques significatives.
