PROCESS TO REDUCE CATALYST FLUIDIZATION IN REGENERATION UNITS

The invention involves a system and a process that reduces the potential for catalyst fluidization in a reduction vessel of a continuous catalyst regeneration system. The gas exit area from the catalyst reduction zone is increased by ventilating the cylindrical baffle of the upper reduction zone. Th...

Summary:The invention involves a system and a process that reduces the potential for catalyst fluidization in a reduction vessel of a continuous catalyst regeneration system. The gas exit area from the catalyst reduction zone is increased by ventilating the cylindrical baffle of the upper reduction zone. This provides an increased exit cross-sectional area for the upper reduction gas to escape and reduce the overall exit velocity of the combined upper and lower reduction gases and reduces the potential for catalyst fluidization. L'invention concerne un système et un procédé qui réduisent le potentiel pour la fluidisation catalytique dans un récipient de réduction d'un système de régénération catalytique continu. La surface de sortie de gaz de la zone de réduction catalytique est augmentée par ventilation du déflecteur cylindrique de la zone de réduction supérieure. Ceci fournit une surface en coupe transversale de sortie accrue pour que le gaz de réduction supérieur s'échappe et réduise la vitesse de sortie globale des gaz de réduction supérieur et inférieur combinés, et réduit le potentiel pour la fluidisation catalytique.
