Out of curiosity, what generates H2S in power plants?
|
Maybe coal? I know H2S is a bigger hazard in coal mines than other kinds of mines due to the geological features of the surrounding rock. That being said, I don't really know much about that so its just speculation on my part.

could be the scrubber agents they are using... caustic meets acid... H2S

The chemistry in how H2S is formed is fascinating. Coal contains some sulfur which releases SO2 when burned. The exhaust is run through a slurry of limestone which causes sulfur to precipitate out as a solid in the form of calcium sulfate (gypsum) rather than letting it into the atmosphere where it can precipitate sulfuric acid into rain.
Sulfur bacteria then eats gypsum and release H2S.

So what I'm hearing here is that if that if the plant owners were lazy and didn't remove the gypsum when they closed down, the precipitation chambers (or whatever they're called) and the room they're stored in if the tanks are leaky with age might be places H2S can accumulate long after the power plant shuts down.

Wow, this is a really interesting thread.
The comments here thus far seem to suggest that many of you are pretty familiar with this topic, so maybe I could get some of your opinions/suggestions on something:
There has been a location on my radar here in Texas that appears to be half-abandoned, half-active. I think it's some kind of oil field operation with an abandoned refinery adjacent to the active portion. Several clues suggest the active and inactive portions are owned by the same company. The front gate has an H2S warning, the other gate has the same warning but just says, "danger; poisonous gas," on it (and the big, scary looking 'no trespassing' signs of course).
The active portion has one of those continuous flames burning off god-knows-what into the air, which clearly indicates activity on site. I know very little about toxic gasses, but I know enough that the sign has given me pause and I have yet to check out the location, even though I suspect it could be pretty damn cool after doing a little bit of research and satellite viewing of the area.
This has been a location goal for 3 or 4 years now, but due to my inexperience with these types of hazards, I've kept putting it off.
How risky would a place like this be if it is (apparently) out in the open air but you don't have access to any analyzers, etc.?
I'm mostly referring to the gas risk, btw, not the risk of getting caught.

Finally,
I had to delve into the archives for the thread, but it's relevant to the discussion. The thread was about "Stormceptors," and evolved from there:

If there's an H2S sign, you have to treat it as a potential poisonous gas environment. Old abandoned H2S sites scare the hell out of me, so I would be super careful. This site however has an active part, which means the gas alarm systems around the site should still be running, and probably also still running in the older parts of the building. They would surely want to know if the abandoned part of the facility started leaking.
Some facility buildings have permanently wired gas detectors mounted near the outside doors, so a person can peek at the monitor before entering the building. Look for them if you do go in a building. (you can Google what they look like)
H2S corrodes metal and can seep through flanges, eating away at the gaskets and causing the paint to peel away on the outsides of the pipes. Even a well-sealed line can leech gas over time, so I would be super careful entering any buildings where there is little air movement.
Personally, wouldn't bother with a site like this. There's plenty of abandoned 'sweet gas' sites out there to explore. To me, it's not worth the risk, even if I had a gas monitor on me. I don't trust abandoned gas sites.
If you go down, it will likely be with no warning and nobody will be equipped to help you or even know you had fallen.
I've seen enough gas leaks and evacuations in controlled environments.. I can't imagine what an abandoned sour gas site would have hiding in it.
That flame you see at the active site is just a flare stack, and it's used to burn off any excess gas coming from a well that they can't deal with and just want to get rid of. Sometimes the well pressure is unstable and a large surge of pressure can overwhelm a facility. A flare stack allows the gas to burn away without causing any harm. The flare also burns any gas that needs to be purged from lines that are undergoing maintenance. It's a safety feature more than anything. One site I was working on had a massive surge of pressure and the flare flame shot up about 100' in the air and sounded like a jet engine. It lit the trees on fire 60' away and we had to immediately report it to Natural Resources. Thankfully the fire didn't spread, but that was on a sour gas site, so imagine if the flame wasn't there and all that gas just drifted freely about!

Here’s a satellite view of the site. Sorry for the shitty resolution, but it was the only way I could get under 100kb on an iPad.
