Reaction in the hydrogenation reactor

It shouldn’t happen, right? If there’s a peroxide combustion sulfur production furnace ahead, SO2 levels will increase, which will lead to an excess of SO2 in the hydrogenation reactor and thus more H2SO3 formation. Moreover, the presence of oxygen will further facilitate the spontaneous combustion of ferrous sulfide. It’s a relatively simple concept to understand.
The presence of oxygen triggers many reactions: it forms SO2 with sulfur, and at the same time it is converted through hydrogenation. Reacting with H2 to produce water is also a hydrogenation reaction. It undergoes an oxidation reaction with sulfided catalysts.
No, under peroxide conditions only more sulfur dioxide can be produced; if the hydrogenation reaction does not proceed completely, this sulfur dioxide will enter the quench tower, resulting in sulfur penetration!
