CA 2251045

A cyclone (310) and process for fluidized catalytic cracking of heavy oils is disclosed. Gas and entrained solids are added tangentially around a vapor outlet tube (320) in a cylindrical tube cyclone body. Solids and some gas are withdrawn via a plurality of openings (316) radially and longitudinally distributed in the cylindrical sidewall (314) of the cyclone. Distributed withdrawal replaces or reduces conventional underflow of solids from an end of cyclone outlet and reduces solids reentrainment. The removal of particles less than 5 microns in size is enhanced by reducing eddy formation and particle bouncing near the cyclone sidewall (314). The device may be used as an FCC regenerator third stage separator.

Cyclone (310) et procédé de craquage catalytique fluidisé d'huiles lourdes. Du gaz et des particules solides entraînées sons introduits tangentiellement autour d'un tube de sortie de vapeur (320) dans un tube cylindrique du corps du cyclone. Les solides et une certaine quantité de gaz sont extraits à travers plusieurs ouvertures (316) réparties le long et sur le pourtour de la paroi cylindrique (314) du cyclone. L'extraction répartie remplace ou réduit le sous-écoulement classique des solides par une extrémité de sortie du cyclone et permet de réduire le réentraînement des solides. L'élimination des particules inférieures à 5 microns est améliorée grâce à la limitation de la formation de remous et à la diminution du rebond des particules contre la paroi (314) du cyclone. L'appareil peut être utilisé comme séparateur de troisième étage d'un régénérateur de craquage catalytique à lit fluidisé.
