Title (EN) IMPROVED SYSTEM FOR FLUIDIZED CATALYTIC CRACKING OF HYDROCARBON MOLECULES
(FR) SYSTEME AMELIORE DE CRAQUAGE CATALYTIQUE FLUIDISE DE MOLECULES D'HYDROCARBURES
Abstract: front page image
(EN)A fluidized catalytic cracking system (10) includes a riser (16) for contacting catalyst and hydrocarbon feedstock. The riser (16) has an inner surface that defines a central passage (17). The central passage (17) acts as a flow path for the catalyst and the hydrocarbon feedstock. A plurality of ribs (29) are disposed on the riser inner surface. The ribs (29) increase the degree of mixing that occurs between the catalyst and the hydrocarbon feedstock within the central passage (17). In particular, each rib (29) has a contoured inner wall (29a). The contour of the inner wall (29a) forces a portion of the catalyst flow inward, toward the hydrocarbon-rich center of the central passage (17).
(FR)La présente invention concerne un système de craquage catalytique (10) comprenant un colonne montante (16) dans laquelle sont mélangés le catalyseur et la charge d'hydrocarbures. La colonne montante (16) comporte une surface interne pourvue d'un passage central (17). Ce passage central (17) sert de chemin d'écoulement pour le catalyseur et la charge d'hydrocarbures. Une pluralité de nervures (29) garnissent la surface interne de la colonne montante. Ces nervures (29) augmentent le degré de mélange entre le catalyseur et la charge d'hydrocarbures dans le passage central (17). Plus précisément, chaque nervure (29) comporte une paroi interne périphérique (29a) qui amène à force une partie du flux de catalyseur vers l'intérieur, en direction du milieu du passage central (17) riche en hydrocarbures.
