Relationship between gasoline copper sheet corrosion and boiling point
Thread Content
Unqualified gasoline copper corrosion issues occur frequently here; how can this be resolved? :)
Copper sheet corrosion is related to the S content in gasoline; high S levels lead to unacceptable levels of corrosion. It is necessary to increase the amount of stripping steam used in the stripper to remove H2S from the oil. The S content in our gasoline is generally below 10.
Thank you! Our thiol compounds are generally up to standard; it’s only the low-pressure gas fed into the company’s overall system that fails to meet the requirements. We suspect that gasri contains oxygen, but we have not provided reasons that satisfy everyone. I’m not sure if this guy is referring to injecting more gas vapor into the fractionation tower
Which refinery is it on the 2nd floor? Dong? ?
Alkalinity in gasoline can also lead to corrosion that does not meet the requirements; pay attention to removing alkalinity, ensure proper control of the temperature used for alkaline cleaning of gasoline, and keep the line speed from being too high.
If the temperature is high, copper corrosion may result in failure to meet specifications; the sulfur content increases with temperature
