Title
(EN) METHOD AND APPARATUS FOR QUENCHING THE COKE DRUM VAPOUR LINE IN A COKER
(FR) PROCÉDÉ ET DISPOSITIF DE REFROIDISSEMENT DE LA LIGNE VAPEUR DU TAMBOUR À COKE D'UN FOUR À COKE
Abstract
(EN)
A method and apparatus for quenching the coke drum vapour line from a coke drum to the main fractionator in a coker unit whereby the volume of quench liquid prevents the drum vapour line from plugging with carbon-based deposits. A differential pressure control technique is utilized to quench the drum vapours being delivered to the fractionator. Vapour line quench control by differential pressure prevents over-quenching of the vapour line during a coke drum switch, unit start-up, or slowdown as well as under-quenching during drum warm-ups.
(FR)
La présente invention concerne un procédé et un dispositif de refroidissement de la ligne vapeur du tambour à coke partant d'un tambour et aboutissant à la colonne de fractionnement d'un four à coke. En l'occurrence, le volume de liquide de refroidissement empêche que la ligne de vapeur ne s'engorge de dépôts carbonés. On a recours à une procédure de régulation de pression différentielle pour refroidir les vapeurs de tambour amenées à la colonne de fractionnement. Cette régulation de pression différentielle de la ligne de vapeur empêche un excès de refroidissement de la ligne de vapeur à l'inversion entre tambours à coke, au lancement de l'appareil, ou à la mise en protection ainsi qu'en cas de refroidissement insuffisant pendant la phase de préchauffage.
