Patent

CA 2236523

The invention relates to a method of returning a finely-divided solid (4) extracted at an extraction point of a reactor vessel (1) from said vessel using a gas to a feed-back point (16) of said vessel. The solid (4) is separated in a solid separator (3), subsequently collected in a collector (8) and fed back from said collector to the reactor vessel (1) using a feed gas. To improve operation of the solid separator (3) without extra loading of the reactor vessel (1), an additional gas flow (23) which is independent of the gas flow in the reactor vessel is circulated through the solid separator (3) in the direction of flow of the solid (4).

L'invention concerne un procédé de renvoi d'un solide (4) à fines particules extrait en un point d'extraction de la cuve (1) d'un réacteur vers un point (16) de recyclage de ladite cuve au moyen d'un gaz de transport. Le solide (4) est séparé dans un séparateur (3) de solide puis collecté dans un collecteur (8) d'où il est renvoyé dans la cuve (1) du réacteur au moyen d'un gaz de transport. Pour améliorer le fonctionnement du séparateur (3) du solide sans pour autant créer une surcharge dans la cuve (1), on fait circuler un flux gazeux (23) supplémentaire, indépendant du flux gazeux contenu dans la cuve, à travers le séparateur (3), dans le sens d'écoulement du solide (4).
