Is it necessary to upgrade the material of the equipment according to the conditions in sulfur chemical production?

There is a hydrogenation unit; for several of the equipment, the operating conditions do not require chromium-molybdenum steel. However, there is a sulfur treatment process that requires the use of a material with enhanced properties according to the Nelson curve – is that necessary? Waiting online for the expert
The Nelson curve was developed for the hydrogen resistance mentioned earlier, not hydrogen sulfide! Additionally, the sulfurization conditions must be taken into account, but chromium-molybdenum steel is not necessarily required
It shouldn’t be necessary. Our vulcanization process also involves raw materials and distillation-related equipment, but no special attention was paid to the material used. However, it seems necessary to pay attention to the dead ends in the pipelines of various devices at the end of the vulcanization process
Generally, there’s no need for deliberate consideration of vulcanization~! If that’s taken into account, the entire setup would need to be made of special materials – so how much would that cost?
