Abstract

La présente invention concerne des réacteurs soumis à une cokéfaction dans des procédés chimiques de craquage d'hydrocarbure. Pendant le procédé de décokage, une cémentation du substrat métallique peut se produire, ayant un impact négatif sur la durée de vie du réacteur. Les décokages sont également coûteux en raison du temps d'indisponibilité où les coûts sont encourus sans production de produits commerciaux. La réduction de la fréquence des décokages fournit une opportunité de réduire les impacts financiers des temps d'arrêt. L'invention concerne une procédure de démarrage qui limite le dépôt de coke initial, conduisant à une tendance réduite à la cémentation du substrat métallique, améliorant la durée de vie du réacteur, et plus important encore, prolongeant la durée de fonctionnement du réacteur.
