Comprehensive and Detailed Explanation From Exact Extract:
Per API RP 571, sulfidation corrosion rates are significantly accelerated by the presence of hydrogen. Hydrogen promotes:
Breakdown of protective sulfide scales
Increased diffusion of sulfur into the metal
Higher metal loss rates
This phenomenon is often referred to as hydrogen-assisted sulfidation and is commonly observed in refinery process units.
Moisture is more closely associated with oxidation mechanisms rather than high-temperature sulfidation.
