Definitions
- the feed exits the furnace at a temperature of preferably 3 450°C and £ 550°C, more preferably of 3 475°C and £ 500°C.
- the heated furnace product stream (C) is transported via a transfer line into a coke drum. It is desirable that the residence time in the transfer line is kept as short as possible, to avoid occurrence of coking prior to reaching the coke drum. Accordingly, it is desirable to keep the transfer line as short as possible.
- a typical configuration may involve two or more, often two, coke drums, so that one drum may be in operation whilst the other drum(s) may be subjected to coke removal and cleaning before switching back in operation again.
- the drum needs to be evacuated from time to time in a batch operation.

Abstract
La présente invention concerne un processus de production de matières premières chimiques à partir de déchets plastiques, le processus comprenant la fourniture d'une configuration de processus comprenant une tour de fractionnement (1), un four (2), une ou plusieurs chambres de cokéfaction (3) et un pré-réacteur (4), conçue de sorte qu'un courant de résidu (A) en provenance de la tour de fractionnement est mélangé avec un courant oligomère (L) et introduit dans le four, le courant de produits en provenance du four (C) est renvoyé dans une chambre de cokéfaction, et un courant de distillat de tête (D) en provenance de la chambre de cokéfaction est renvoyé dans la tour de fractionnement ; le courant oligomère (L) étant obtenu sous la forme d'un courant de produits de la conversion d'un courant de déchets plastiques (B) dans le pré-réacteur, et ayant une masse moléculaire moyenne en poids comprise entre 5 000 et 10 000 g/mol. Un tel processus permet la conversion d'un grand choix de déchets plastiques en produits chimiques valorisables. En outre, un tel processus permet d'augmenter la production de produits hydrocarbonés de gamme naphta qui peuvent être utilisés pour la production, par exemple, d'un nouveau produit polymère thermoplastique par conversion dans des installations de vapocraqueurs.
