Title (EN) BAFFLES FOR IMPROVING RISER HYDRODYNAMICS
(FR) DÉFLECTEURS POUR AMÉLIORER L'HYDRODYNAMIQUE DES COLONNES MONTANTES
Abstract:
(EN) Fluid catalytic cracking units having risers with improved hydrodynamics through the use of baffles are described. The baffles break up the high concentration of catalyst in the slower moving outer annulus and redistribute it into the faster moving, more dilute center of the riser flow.
(FR) La présente invention concerne des unités de craquage catalytique sur lit fluidisé présentant des colonnes montantes dotées d'une hydrodynamique améliorée grâce à l'utilisation de déflecteurs. Les déflecteurs cassent la forte concentration de catalyseur dans l'anneau externe à déplacement plus lent et la redistribue dans le centre plus dilué à déplacement plus rapide de l'écoulement des colonnes montantes.
