The present invention is a method for detecting an abnormal event for process units of an ethylene processing system. The method compares the operation of the process units to a model developed by principal 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 procédés de détection d'événement anormal d'unités de traitement d'un système de traitement d'éthylène. Ce procédé compare le fonctionnement des unités de traitement à un modèle élaboré par une analyse des composantes principales du fonctionnement normal de ces unités. Si la différence entre le fonctionnement d'une unité de traitement et le fonctionnement normal indique un état anormal, la cause de cet état anormal est alors déterminée et corrigée.
