Question: What is the reaction of hydrogen sulfide with metals? Answer: H2S can react with most metals to form sulfides; it can also form sulfides with other oxidizing agents, especially when heated or in the presence of water vapor. For example: 2H2S + Fe → FeS↓ + 2H2↑. H2S can severely corrode steel (equipment, pipes, etc.), so during shutdown purging, nitrogen is generally used as the purging medium, with the aim of preventing steam and H2S from accelerating corrosion by reacting with metals.
It can react with most metals to form sulfides, and especially in the presence of heat or water vapor, it can also form sulfides with other oxidizing agents. For example: 2H.

H2S can react with most metals to form sulfides, especially when heated or in the presence of water vapor. It can also react with other oxidizing agents to produce sulfides; for example: 2H2S + Fe → FeS (precipitate) + 2H2 (gas). H2S can cause severe corrosion of steel (equipment, pipes, etc.), which is why nitrogen is generally used instead of steam during shutdown and purging processes – the aim being to prevent steam from accelerating the reaction between H2S and metals and thereby causing corrosion.

Answer: H2S can react with most metals to form sulfides; it can also form sulfides with other oxidizing agents, especially when heated or in the presence of water vapor. For example: 2H2S+Fe→FeS
H2S can react with most metals to form sulfides; it can also form sulfides with other oxidizing agents, especially when heated or in the presence of water vapor. For example: 2H2S + Fe → FeS↓ + 2H2↑. H2S can severely corrode steel materials (equipment, pipes, etc.). Therefore, during shutdown and purging processes, nitrogen is generally used as the purging medium. The purpose is to prevent H2S vapor from accelerating its reaction with metals, thereby causing corrosion
