Does type II wet hydrogen sulfide corrosion involve water?
Thread Content
Type II wet hydrogen sulfide corrosion: Can the corrosion environment for Type II wet hydrogen sulfide corrosion be free of water? In version 20 of 20581, 6.8.2 explicitly refers to free water, while 6.8.3 only mentions the liquid phase; there is a clear difference between the two. SH/T3193-2017 defines both as liquid water. I don’t know which one to use? I remember posting it in the Corrosion section before; I don’t know how it ended up in the Process forum:L
Post it in the industry community to see if any experts know about it
Free water or liquid phase – it’s still water
As for free water, there’s no doubt about it; in the case of type II hydrogen sulfide corrosion, it refers to the liquid phase, with no specific mention of water
Could you help move it? I’m not very good at figuring out how to send it
The necessary condition for a wet hydrogen sulfide corrosion environment is the presence of water
I think the same way, but in the new version 20581-2020, there is a difference between sections 6.8.2 and 6.8.3: the clause regarding free water falls under 6.8.2, while it isn’t mentioned in 6.8.3. Since these two clauses are presented side by side, this confusion arises.
We have been using hydrogen sulfide in humid environments at the Dazhou Natural Gas Purification Plant for ten years now, and the results are good
Liquid, gas, solid. . . . .
