Copper sheet corrosion issue
Thread Content
The sulfur content in the diesel is 9PPM, and the copper sheet corrosion test results show a grade of 3B. What’s going on here? Can mixing in other diesel help to get the copper sheet corrosion rating to meet the requirements?
There is no alkali washing for the diesel output unit; if alkali washing were done, it might be due to alkali corrosion； Secondly, check whether the diesel contains water; if it does, hydrogen sulfide present in the water can cause corrosion, resulting in failure to meet the standards.
Could we conduct a doctoral-level experiment to see? Or check if there is hydrogen sulfide
Use a desulfurization device to achieve effective desulfurization
The one on the 2nd floor, has studied *. If there is H2S, desulfurization will not be thorough.
Copper sheet corrosion is mainly caused by hydrogen sulfide and elemental sulfur; it is necessary to conduct a targeted analysis of the reasons for the corrosion failure to determine whether it is caused by hydrogen sulfide or some other factor. Agree with the person above; the one up there
