Corrosive components in gasoline
Thread Content
Why does hydrogenated gasoline have high corrosivity, even though its sulfur content is less than 10 ppm?
Hydrogenated gasoline inevitably contains some hydrogen sulfide; by removing this hydrogen sulfide completely, corrosion can be reduced.
It has been completely cleaned, but the rusting test still shows severe issues
Hello, may I ask why severe rusting occurs when there is a high amount of olefins?
The corrosive components in gasoline mainly include sulfur and reactive sulfides (such as H2S, S, RSH, etc.), as well as water-soluble acids and bases.
Take a look at the operations related to hydrogen addition at high and low levels to see if backmixing has occurred. Generally, it’s sufficient to keep the hydrogen sulfide level low, and try to maintain a slightly lower oil level.
