Corrosion Inhibitor for oilfield

Definition of Oil and Gas Corrosion Inhibitors:

Generally, corrosion inhibitors refer to substances that provide protective effects on metal surfaces. Adding small or trace amounts of these chemical substances can significantly reduce the corrosion rate of metal materials in a given medium.

Corrosion inhibitors can be categorized based on their application into the following types: acidizing corrosion inhibitors, oilfield wastewater corrosion inhibitors, gathering and transportation corrosion inhibitors, and refinery corrosion inhibitors.

Imidazoline Corrosion Inhibitors are a type of organic adsorption corrosion inhibitor. Imidazoline corrosion inhibitors are typical and among the most widely used organic corrosion inhibitors. The anti-corrosion effect of organic corrosion inhibitors on metals primarily works through two mechanisms: adsorption by polar groups, or hydrophilic groups, and shielding by non-polar groups.

Corrosion Inhibition Mechanism: Imidazoline corrosion inhibitors adsorb onto the metal surface through their polar groups, while the non-polar groups are directionally arranged on the metal surface, forming a hydrophobic film. Upon adsorption onto the metal surface, the corrosion inhibitor alters the charge distribution and interfacial properties of the metal surface, stabilizing the energy state of the metal surface. This increases the activation energy of the corrosion reaction, thereby inhibiting corrosion.
