General
Refinery Corrosion Inhibitor ZX-C3-04 is a water-soluble corrosion inhibitor mainly used at the top of the refinery towers and composed of composite pyridine quaternary ammonium salt as main ingredients and some synergist. It has a good protection functions for condensation and cooling system from HCl-H2S-H2O dew point corrosion. This corrosion inhibitor has certain neutralization and filmformation functions. It can evidently prevent the corrosion media from metal corrosion , and a good inhibition performance to naphthenic acid, CO2.
The acidic substances in the oil (such as HCl and H2S) are neutralized by organic amine components to adjust the pH value of the medium to the neutral range of 6.7-7.7. Meanwhile, the active ingredients are directionally adsorbed on the metal surface to form a dense protective film. Experiments have confirmed that this film layer can reduce the iron ion concentration to below 2ppm, achieving physical blocking of the contact with corrosive media. Alkyne alcohol compounds and auxiliary surfactants work together to enhance the impermeability of the film layer, maintaining stable protection even in high-temperature and high-acid environments.
