  • METHOD AND SYSTEM FOR DETECTING ABNORMAL OPERATION IN A HYDROCRACKER
    Publication number: 20110295545
    Abstract: A system and method for detecting abnormal operation of a hydrocracker includes a model to model the hydrocracker. The model may be configurable to include one or more regression models corresponding to different operating regions of the portion of the hydrocracker. The system and method may also determine if a monitored temperature difference variable deviates significantly from the temperature difference variable predicted by the model. If there is a significant deviation, this may indicate an abnormal operation.
