That's a good point, Albina. Stagnate areas could definitely contribute to sulfidation.

I'm not sure, but I think it could also be D) Elemental sulfur collecting in stagnate areas.

Sulfidation, huh? Sounds like a good name for a heavy metal band. 'Sulfidation' - I can already hear the sick guitar riffs!

E) Operators failing to control the pH of sulfur streams? Sounds like someone's trying to sneak in a trick question here.

I'm going with C) Sulfur compounds being created in the FCCU. That's where a lot of sulfur-containing feedstocks get processed, so it's a logical source.

I agree with option C as well, the FCCU seems like a likely culprit for sulfidation.

D) Elemental sulfur collecting in stagnate areas makes sense too. Dead legs and other low-flow zones can be a breeding ground for sulfur buildup.
