AI Overview
Oil refinery passivators are chemical additives, such as metal deactivators (e.g., ToluilTriazolAmmina, CUVAN® 484), used to bind to reactive metal surfaces or contaminants to prevent corrosion, degradation, and unwanted catalysis. They protect equipment by forming a passive, unreactive film. In Fluid Catalytic Cracking Units (FCCU), specialized agents immobilize nickel and vanadium, reducing hydrogen and coke formation to improve product yield.
