Iron Sulphide: Friend or Foe?

摘要

In sour gas production there are two primary corrosion causing species: hydrogen sulphide (H_2S) and carbon dioxide (CO_2). The corrosion products that form from the reaction of these gases with steel in the presence of water can provide a clue as to the formation mechanism, the severity of the potential corrosive environment and the degree to which the corrosion will affect operation of an amine unit.
