Title (EN) SILICONE FREE ANTI-FOAMING PROCESS AND CONTROLLED FOAMING PROCESS FOR PETROLEUM COKING
(FR) PROCÉDÉ D'ANTI-MOUSSAGE SANS SILICONE ET PROCÉDÉ DE MOUSSAGE RÉGULÉ POUR LA COKÉFACTION DE PÉTROLE
Abstract:
(EN) The current invention provides an improved petroleum coking process wherein the risk of silicone poisoning of units downstream of the coke drums is eliminated. The method of the current invention controls the foam layer within the coke drum by injection of a non-silicone anti-foam agent, preferably a tire oil. In another embodiment, the current invention provides a controlled foaming method which increases the liquid production from the coke drum. In the controlled foaming method, an anti-foam agent is cyclically injected into the drum early in the coke drum fill cycle. The cyclic injections manage the foam layer without inducing the induction phase in the coke feedstock, thereby increasing the total volume of feedstock received by the coke drum.
(FR) La présente invention concerne un procédé amélioré de cokéfaction de pétrole, selon lequel le risque d'empoisonnement par de la silicone des unités en aval des fours à coke est éliminé. Le procédé selon la présente invention régule la couche de mousse dans le four à coke par injection d'un agent anti-mousse sans silicone, de préférence une huile pour pneus. Selon un autre mode de réalisation, la présente invention concerne un procédé de moussage régulé qui augmente la production de liquide à partir du four à coke. Selon le procédé de moussage régulé, un agent anti-mousse est injecté cycliquement dans le four au début du cycle de remplissage du four à coke. Les injections cycliques régulent la couche de mousse sans induire la phase d'induction dans la matière première de la cokéfaction, ce qui augmente le volume total de la matière première reçue par le four à coke.
