Corrosion Inhibitor is chemicals that are added to a chemical stream to prevent corrosion or lower the rate of corrosion so that the processing equipment will have a suitable service lifetime. Corrosion inhibitors are often the most cost-effective way to prevent or control corrosion because they allow one to use less expensive metals for a corrosive environment.
Mechanism of Corrosion Inhibitor
• The inhibitor is chemically adsorbed (chemisorption) on the surface of the metal and forms a protective thin film with inhibitor effect or by a combination of inhibitor ions and metallic surface;
• The inhibitor leads a formation of a film by oxide protection of the base metal;
• The inhibitor reacts with a potential corrosive component present in aqueous media and the
product is a complex.
Application :::
1.) Acid pickling: Prevent the attack in the metal due to the acid solution in which metal gets
cleaned of mill scale (bark lamination), and also prevented the subsequent hydrogen evolution inhibitors are added, typically organic, must be soluble or dispersed in the solution.
2.) Oil industry: Corrosion is caused
by the dissolution of the corrosive gases, such as carbon dioxide and hydrogen sulfide as well
as condensation of acid vapors. Sodium carbonates or organic amines complex is employed to reduce the corrosive effect of CO2, H2S, and organic acids.
3.) Water transmission and distribution systems: The most common inhibitors are phosphates, amines volatiles. It is used as a corrosion inhibitor in combination with pH adjusters and alkalinity control towards an efficient protection.
4.) Concrete: To improve the durability of reinforced concrete structures, which are impaired due to the high alkalinity, are used corrosion inhibitors, mixed with cement or concrete paste.
5.) Boiler: Ammonia, Cyclohexylamine, alkanol, and Morpholine are used as inhibitors in boilers in various processes. The inhibitors are added by the hydrochloric acid used for the solubilization of limescale to prevent the attack on pipes.
