Hydrogen production from coking dry gas
Thread Content
Hydrogen and oxygen production from coking dry gas: After advanced A desulfurization, the total sulfur content was 0.25 ppm, while after B desulfurization, it was 3 ppm. (The B reactor has a newly installed zinc oxide desulfurizer) What could be the reason? ?
First, verify whether the sampling bag has been properly replaced； Second, contact the laboratory to confirm whether there are any issues with the analysis instruments ； Third, verify whether there is any internal leakage in the connection line between the two desulfurization tanks.
If sampling is fine, then it’s an analysis error; the level is only one or two PPM, so sampling and analysis errors are likely to occur.
Let’s consider the sampling error; try taking samples again
It is usually due to sampling and analysis errors, and there might also be some internal leakage in the cross-connected lines. By the way, how often do you replace your zinc oxide desulfurizer?
