I'm sure. H2S smells like rotten eggs. There is also CS2 (Carbinyl sulfide), but it comes in lower concentrations. There are tons of desulfurization plants near you. There are also lots of Natural Gas "sweetening" units.
They are taking Sulfer out of the petroleum products and then burning either burning it in an incinerator or capturing it in sulfer pits.
An upset should go straight to a flare. It looks like a giant torch. If you smell something, but don't see a flare, then there could be a problem. This is Bad. You should call the TNRCC it you keep smelling it.
Thanks for adding your voice to the concern of others, and me too.
This isn't right...and after you smell something for a while, you can get dulled to it...
Whoops! COS=Carbinyl Sulfide, CS2= Carbon disulfide, H2S=Hydrogen Sulfide
Woo. I keep dreamin' of heading to the northwest part of town... may be time to look harder...
Oh, and the upset-then-flare sequence, that I knew about. See it a LOT around here, lights up the sky beautifully... not!
