Title
(EN) REMOVAL OF CATALYST FINES FROM A REACTION SYSTEM
(FR) RETRAIT DE FINS DE CATALYSEUR D'UN SYSTEME DE REACTION
Abstract
(EN)
This invention provides a process for limiting the loss of catalyst particles through olefin product streams and regenerator flue gas streams exiting the reaction system. In particular, this invention provides for removing catalyst particles from the reactor using a water stream and from the regenerator using a two step separation process. The two step process involves the use of a catalyst fine separation unit.
(FR)
La présente invention concerne un processus permettant de limiter la perte des grains de catalyseur dans des courants de produits oléfiniques et des courants de gaz de combustion de régénérateur sortant du système de réaction. En particulier, l'invention concerne le retrait des grains de catalyseur en provenance du réacteur en utilisant un courant d'eau et en provenance du régénérateur en utilisant un processus de séparation en deux étapes. Le processus en deux étapes comprend l'utilisation d'un module de séparation des fins de catalyseur.
