Method and apparatus for monitoring amounts of submerged solid consumable. A GWR (Guided Wave Radar) component can provide a measurement of a reflection at a fixed position in a particle bed. The reflection represents aggregate dielectric properties in a vessel. The measurement includes hydrocarbon and solid consumable properties of a mixture in the vessel, wherein a measurement value is indicative of a greater amount of the solid consumable in the mixture in the vessel. If data is measured by the GWR component indicating that the measurement value is approaching the measurement value of the hydrocarbon, this data is indicative that the material (e.g., solid consumable such as salt) in the vessel should be replenished.

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.
