You folks are good(informed). What about the gas that comes to our homes? Can’t that be a source?
No, there are scrubbers to take H2S out before it gets to the end-use pipeline, plus an additional chemical to give (gas you use) a smell that you recognize.
Frequently you will see big piles of yellow stuff next to a processor. That’s the sulfer by-product
Aside from the safety factor, they also take H2S out because it causes what is called “embrittlement” to the pipes. To over-simplify, hyrdogen atoms break off and float into the steel and make it more like cast iron — brittle, instead of bendy.
I deal with this in drill pipe, and it is why you often see pipe that looks good sitting out in the baking Sun for a couple months -— the heat and light bakes out the H+ and the pipes go back to normal.
You could end up dealing with this on internal pipeing, which makes for fragile connections.
Thackney is very correct re: H2S smell. We have monitors and breathers in the chicken coops for this reason. Buzzer goes off — RUN.
Never happened yet, and won’t, God willing.
I have, however, been on a drilling site where a guy falls down in the cellar (the underground part of a well being drilled) -— he’s dead from H2S. Good buddy goes to help -— and he dies.
My one and only brush with the legal system was testifying in this case about how they all violated their training about masks, alarms, etc.
Posting to confirm all the TheThirdRuffian said.
The nat gas at your house has been cleaned. It is nearly pure methane.
