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?
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.
