Application:

Almost all organic molecules used as corrosion inhibitors in oil and gas are highly polar and mainly nitrogen-based (such as amines, amides, imidazolines and quaternary ammonium salts). Nitrogen-based organic inhibitors such as polyamidoamines and imidazolines and their salts have been successfully used in this type of applications. The mechanism of action of this type of material is their surface absorption on the metal surface and creation of an interface layer. The ability of these compounds to create cations causes their strong surface adsorption on negatively charged surfaces such as metals and turns hydrophilic surfaces into hydrophobic ones. With this action, cathodic and anodic reactions are prevented. This product is used to prevent corrosion in tubing and wellhead equipment of oil wells and oil and gas fluid transmission pipelines, transmission and process systems related to sour water (such as stripping towers), process equipment (such as the overhead of distillation towers in the oil and gas, refining and petrochemical industries, which have a high H2S content (25% or higher)).
