Abstract

La présente demande de brevet décrit des modifications de conception d'ingénierie à la sortie VSS, à l'entrée de puits marginal et aux pieds plongeants de cyclone principaux pouvant réduire significativement le soupassement des produits de colonne montante de réacteur dans le puits marginal et le caisson de réacteur et ainsi produire de plus grandes sélections de produits souhaités et améliorer l'efficacité du dégazolinage et du gaz d'évent du puits marginal qui circule continuellement dans le caisson de réacteur selon un faible potentiel de formation de coke en raison de sa faible concentration d'éthylène et de sa matière à masse moléculaire élevée, qui peut être récupérée séparément des produits de colonne montante principaux.
