Metal passivator
Thread Content
Please discuss in more detail the specifications, types, and applications of metal passivators.
Regardless of the passivator you use, whether the addition is appropriate depends mainly on whether the antimony-nickel ratio and the hydrogen-methane ratio in the dry gas are within normal ranges. Use it sparingly while meeting the requirements.
The most commonly used types of catalyst materials are passivated nickel and vanadium
Could someone with experience provide the specifications for metal passivators used in various refineries? (No code is required; it’s better if there are detection metrics.)
