Title
(EN) GAS INJECTION ELEMENT FOR A FLUID CATALYTIC CRACKING UNIT AND GAS DISTRIBUTION SYSTEM EQUIPPED WITH THIS INJECTION ELEMENT
(FR) ELEMENT D'INJECTION DE GAZ POUR UNITE DE CRAQUAGE CATALYTIQUE FLUIDE ET SYSTEME DE DISTRIBUTION DE GAZ EQUIPE DE CET ELEMENT D'INJECTION
Abstract
(EN) A gas injection element (10) for a system for distributing a gas inside a chamber of a fluid catalytic cracking unit. This injection member comprises a passage (14) extending entirely therethrough, and - an inner ceramic member (20) having an inner surface (22) that entirely delimits the through-passage (14); and - a hollow metal sleeve (30), inside which at least a portion of the inner member (20) is received, the sleeve (30) and the inner member (20) respectively having an inner surface (32) and an outer surface (24) with matching shapes allowing the inner member (20) to move relative to the sleeve (30) in a direction parallel to an axis (X) of the passage (14), the outer (32) and inner surfaces (24) being provided with fastening elements (26, 36) that engage to reversibly fasten the sleeve and the inner member.
(FR) L'invention concerne un élément d'injection de gaz (10) pour un système de distribution de gaz à l'intérieur d'une enceinte d'une unité de craquage catalytique fluide. Cet élément d'injection comprend un passage (14) le traversant de part en part et - un élément interne (20) en matériau céramique dont une surface interne (22) définit entièrement le passage traversant (14), - un fourreau métallique creux (30), à l'intérieur duquel est logée au moins une partie de l'élément interne (20), le fourreau (30) et l'élément interne (20) présentant respectivement une surface interne (32) et une surface externe (24) de formes complémentaires autorisant un déplacement de l'élément interne (20) par rapport au fourreau (30) suivant une direction parallèle à un axe (X) du passage (14), ces surfaces interne (32) et externe (24) étant pourvues d'éléments de fixation (26, 36) coopérant pour fixer de manière réversible le fourreau et l'élément interne.
