Vanconol® ET-105 Acidizing Corrosion Inhibitor
Product Overview
In the petroleum industry, acidizing is used to stimulate oil and gas well production and to enhance injection in water injection wells. The acid fluids used in acidizing operations can cause severe corrosion of pipelines and equipment. Vanconol® ET-105 acidizing corrosion inhibitor withstands high temperatures and concentrated acids, offers good solubility and dispersibility, is environmentally friendly and contains no chloride ions. It is designed for acidizing operations in oil and gas wells and for industrial acid cleaning.
Chemical Description
A combination of modified Mannich base, specialty surfactants and synergists.
Mechanism of Action
Heteroatoms such as N within the molecule and metal-affinic anchoring groups rapidly adsorb onto the metal surface to form coordinate bonds, creating a monomolecular adsorption film. This film prevents the corrosive medium from contacting the metal, slows the electrode reaction rate and protects the metal surface.
