Abstract

The measurement of ‘Level’ is crucial in an Industrial Process, as low levels can cause problems and damage equipment. In contrast, high levels can cause overflow and potentially create safety and environmental problems. When working with the Fluid Catalytic Cracking System Unit (FCCU) in Refineries, there are requirements for various types of level measurement instruments. One of them is the Nucleonic Level Measurement device used in the process involved in the separation of catalyst from the Flue gasses passes through types of equipment such as Third Stage Separator, Fourth Stage Separator, Fines Collection Hopper, Fines Disposal Hopper, and End Level Drums or Bins. Nucleonic level measurement works upon radiometric level measurement techniques in which sources and detectors transmit and receive gamma rays to detect the catalyst level of hoppers/vessels. The following are the advantages of Nucleonic Level Measurement: ● Used in level, interface, density, concentration, and point-level measurement ● It can utilized for measurement in liquids, solids, suspensions, or sludges ● It’s also used in extreme process conditions: high pressure, high temperature, corrosion, abrasion, viscosity, toxicity, and all kinds of process vessels, for example, reactors, autoclaves, separators, acid tanks, and cyclones.
