Oxygenated process water corrosion
WebApr 5, 2024 · How Does Salt Water Rust Metals? Iron oxide, a reddish-brown compound, is normally referred to as rust. It forms when iron and oxygen react in water or in moisture in the air. The reaction of iron and chloride underwater is also referred to as rust. Certain factors speed up the rusting process, such as salt in the water. WebIn the presence of oxygen, the corrosion process described above is modified. Dissolved oxygen replaces hydrogen ions in the reduction reaction. The reactions are as follows: Oxidation: Reduction: Overall: This reaction occurs more readily than the direct reaction between iron and protons.
