Title (EN) PROCESS FOR INCREASING ETHYLENE AND PROPYLENE YIELD FROM A PROPYLENE PLANT
(FR) PROCÉDÉ POUR AUGMENTER LE RENDEMENT D'ÉTHYLÈNE ET DE PROPYLÈNE D'UNE INSTALLATION DE PRODUCTION DE PROPYLÈNE
Abstract:
(EN) The disclosure provides a process for recovery of C2 and C3 components in an on-purpose propylene production system utilizing a packed rectifier with a countercurrent stream to strip C2 and C3 components from a combined de-ethanizer overhead lights vapor and cracked gas vapor stream.
(FR) La présente invention concerne un procédé pour la récupération de composants C2 et C3 dans un système de production de propylène spécifique utilisant un rectificateur compact avec un flux à contre-courant pour réextraire les composants C2 et C3 d'un courant combiné de vapeur de gaz craqué et de vapeur de composants légers de produit de tête de dééthaniseur.
