- hydrogen sulfide is an industrially important intermediate, for example, for the synthesis of methylmercaptan, dimethyl sulfide, dimethyl disulfide, sulfonic acids, dimethyl sulfoxide, dimethylsulfone and numerous sulfidation reactions.
- the synthesis of hydrogen sulfide from the elements hydrogen and sulfur is usually carried out by introducing hydrogen into liquid sulfur and a downstream reaction space in the gas phase. Both catalysed and uncatalyzed processes are known.

If the removal is between 0.1 and 0.3 mm / a, then this can usually be compensated for a long-term operation of the reaction vessel by a corrosion allowance. Abrasions> 0.5 mm / a would lead to massive clogging of equipment and piping as well as significantly increased material costs, high maintenance costs and greater safety risks.
- reaction vessel only partially from the very durable material, for example, if certain semi-finished products are not available in the desired dimensions or are then very expensive.

Since the corrosion behavior depends strongly on the temperature and the temperature can be different within the reaction vessel, can also Only the parts of the reaction vessel, which are exposed to high temperatures during the course of the reaction, consist of the resistant material with the desired low removal rates, while the remaining part is made of other materials with possibly higher removal rates.
