Do sulfur dioxide and hydrogen sulfide coexist in industry?
Thread Content
Do sulfur dioxide and hydrogen sulfide coexist in industry? According to high school chemistry theory, the two cannot coexist! But take a look at the following figures: Sulfur recovered in exhaust gases / mg·m‑3 H2S SO2 38160 17240 23100 4350 4360 78100 68120 9360 9250
It’s urgent! Waiting online for the answer! Everyone, please help!
Why can’t they coexist? Their reaction is also conditional.
Middle school chemistry covers theoretical situations; in reality, if sulfur dioxide and hydrogen sulfide coexist indefinitely, a reaction will certainly occur, and after a long time only one of them will remain
The reactions of both are limited by the thermodynamic equilibrium conversion rate; if this is not accepted, then there is no point in discussing them.

Under certain conditions, the reaction has a limit; after coming out of the Claus furnace and passing through the sulfur reactor, has the reaction been complete? Of course, if you insist on keeping a mixture of the two in a bottle for 10,000 years, they certainly won’t coexist. Theoretically, most inorganic chemical reactions are complete; what the original poster is asking is whether these two substances can coexist on an industrial scale. Moreover, data from high school chemistry is cited here – since the environment differs, a specific analysis is necessary.
I discovered a secret: when hydrogen sulfide levels in exhaust gases are high, sulfur dioxide levels tend to be low. . . When the former is low, the latter becomes high again!
Before the CLAUS exhaust gas is subjected to hydrogenation, both of these are definitely present, along with elemental sulfur and sulfides; their concentrations depend on the air supply conditions in the acid gas furnace.
