Title
(EN) REACTOR RISER OF A FLUID CATALYTIC CRACKING PLANT
(FR) COLONNE DE MONTEE DE REACTEUR D'UNE INSTALLATION DE CRAQUAGE CATALYTIQUE FLUIDE
Abstract
(EN)
Reactor riser (1) of a fluid catalytic cracking plant, which reactor riser (1) has an axial passageway (5) extending between an inlet end for receiving hydrocarbonaceous feed and catalyst particles and an outlet end for discharging effluent and catalyst particles, which reactor riser is provided with a plurality of contacting devices (6, 7, 8) arranged axially spaced apart in the axial passageway (5), wherein each contacting device (6, 7, 8) comprises a mixing element (10) having the shape of a segment of arc.
(FR)
L'invention concerne une colonne de montée (1) d'un réacteur d'une installation de craquage catalytique fluide. Cette colonne (1) présente un passage axial (5) qui s'étend entre une extrémité d'entrée pour recevoir une alimentation hydrocarbonée et des particules de catalyseur et une extrémité de sortie pour décharger l'effluent et les particules de catalyseur. Cette colonne de montée est pourvue de plusieurs dispositifs de contact (6, 7, 8) disposés de manière axiale par rapport au passage axial (5). Chaque dispositif de contact (6, 7, 8) comprend un élément de mélange (10) ayant la forme d'un segment d'arc.
