I would like to ask if there is SO3 in Klaus exhaust gas?

Theoretically, it is possible; acid dew point corrosion is generally calculated based on a 5% conversion of SO2
Will it happen with air or an excess of oxygen?

This kind of thing definitely happens; we suffered a big loss in 2013 due to ignorance – just one week after maintenance work started, the newly installed catalysts became completely useless. Attempting to reduce the air supply in order to restore normal performance had no effect at all. Fortunately, the operating load of our sulfur unit is very low; we have another sulfur unit that can be switched to, and the catalyst was replaced immediately. Moreover, our unit is designed on a relatively small scale, so the cost of replacing the catalyst in that instance was no more than 140,000 yuan.
Will there be no SO3 if there are trace amounts of H2S in the exhaust gases?
Too much air will result in SO3, right?
SO3 is based on SO2; in other words, SO2 exists first, and then SO3 is formed. Meanwhile, H2S is the basis for SO2!
Excess oxygen will oxidize SO2 to SO3; when SO3 enters the reactor, the catalyst is destroyed – is that the reason?
At what temperature do your catalysts become unusable?
