Liquid hydrogen sulfid corrosion 1

[TomSt]

Does anybody have any experience handling liquid hydrogen sulfide?

 

[JLSeagull]

Many have experience with hydrocarbon liquid that is rich in hydrogen sulfide. Do you mean high pressure liquified pure or nearly pure H2S or HC liquid?

 

[TomSt]

By liquid hydrogen sulfide, I mean pure or nearly pure H2S, not HC with H2S contamination.

Dry LHS is a pain to handle, but non-corrosive.
Add a small amount of water and all hell breaks loose. I built a pump a number of years ago to handle dirty LHS. We used modified alloy 'C' (C-22, 59 or 686) for everything.
