Why did the oxygen content increase after desulfurization? ?
Thread Content
After 12 hours of shutdown for maintenance, the oxygen content was 0.15 at the sample point after the blower, and 0.8 after desulfurization. Is it because of the coke being just taken out of the furnace, or is the problem in the desulfurization unit? Is there a possibility of cross-connection when there is an excess of air in the desulfurization section?
What is your unit? Milligrams or grams?
It must be the volume percentage; we hadn’t noticed that before. It’s possible for the desulfurization lean liquid to contain dissolved air, but would the level be this high?
How does your company remove sulfur?
Leakage is more likely. Could it also be a problem with the instrument display?
Was no sample added at that time? Laboratory equipment or laboratory technicians can also make mistakes, but the possibility of air leakage cannot be ruled out either.
