The present invention is a method for detecting an abnormal event for process units of a hydrocracking unit. The method compares the operation of the process units to a model developed by principle components analysis of normal operation for these units. If the difference between the operation of a process unit and the normal operation indicates an abnormal condition, then the cause of the abnormal condition is determined and corrected.
La présente invention concerne un procédé de détection d'un évènement anormal dans des unités de traitement d'une unité d'hydrocraquage. Ledit procédé consiste à comparer l'exploitation des unités de traitement à un modèle mis au point par analyse des composants essentiels d'une exploitation normale desdites unités. Si la différence entre l'exploitation d'une unité de traitement et l'exploitation normale indique un état anormal, la cause de l'état anormal est alors déterminée et corrigée.
