Abstract
Systems and methods are disclosed for detecting temperature excursion in a chemical plant or petrochemical plant or refinery. Aspects of the disclosure provide an enhanced control system for a reactor, such as in hydroprocessing. The enhanced control system may provide early warnings of impending undesirable events, directly or indirectly manipulate certain process variables to reduce undesirable outcomes, and/or directly or indirectly manipulate of certain process variables so as to place a reactor unit in a 'safe park' state. This may avoid a high temperature trip, depressuration, associated operating risks, allow for faster recovery from temperature excursions, and/or avoid unplanned emergency shutdowns of the reactor, chemical process, plant, or refinery.
