Title (EN) METHOD FOR UPGRADING STEAM CRACKER TARS
(FR) PROCEDE D'AMELIORATION DE GOUDRONS DE VAPOCRAQUEUR
Abstract:
(EN) A process for the production of gaseous olefins which involves introducing a hydrocarbon feedstock stream into a high temperature thermal cracking zone to produce a high temperature cracked product stream, quenching the cracked product stream to stop the cracking reactions, injecting at least one HDD (hydrogen donor diluent) into the cracked product stream at or downstream of the point at which the reaction is quenched, recovering normally gaseous olefins from the cracked product stream, and recovering a liquid product stream containing a diminished asphaltene content.
(FR) Procédé de production d'oléfines gazeuses consistant à introduire un courant d'une charge d'alimentation d'hydrocarbure dans une zone de craquage thermique à haute température afin de produire un courant de produits craqués à haute température, à refroidir le courant de produits craqués afin de stopper les réactions de craquage, à injecter au moins un DDH (diluant donneur d'hydrogène) dans le courant de produits craqués au niveau ou en aval du point auquel la réaction est refroidie, à récupérer normalement des oléfines gazeuses du courant de produits craqués, et à récupérer un courant de produits liquides présentant une teneur en asphaltène diminuée.
