Does anybody have any experience handling liquid hydrogen sulfide?
 
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?
 
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.
