h2s partial pressure
h2s partial pressure
(OP)
i am checking on the maximum h2s partial pressure in the gas pipeline (wet gas) before the sulfite stress cracking begin to occur. is there any rule of thumb for the h2s partial pressure?
Thanks in advance.
Thanks in advance.

The H2S partial pressure limits vary with the type of steel you are using in the given environment. For details refer to NACE MR 0175, I've seen 15 psi and above for carbon steel, etc...

From memory, if under 750 ppm, it is based on partial pressure. If over 750 ppm, it is based on total pressure.
You should go through the NACE MR-01-75 document.
