materrial vessel for h2s removal

[rudiawan .]

hi dear..
i need advise for materrial selection for h2s removal pressure vessel for gas

this pressure vessel will be used for h2s removal which the inlet gas contain sulfur 150 ppm
the pressure inlet is 15 psig, and the gas temeprature 125 deg.F
ijust thinking to use carnon steel with suitable material for cladding
please advise which material should be used for pressure vessel
pressure diameter is 3.2 meters, and tangent to tangent length is 6 meters
the gas composition also attached

at your service conditions I think you can use a carbon steel hic resistent according to NACE Requirements

inlet gas contain sulfur 150 ppm ... please advise which material should be used for pressure vessel

This does not work such way. One need to identify the whole range of T&P&composition of fluids inside during all cases possible including abnormal conditions.

Please describe your background in process/corrosion engineering.

Do you realize that H2S has extremely low acute toxicity and even a negligible leak is able to cause mass casualties?
