Oil Refining Auxiliary

HLN-129 is a high-performance phosphorus-free high-temperature corrosion inhibitor formulated by diluting the stock solution with diesel oil, aromatic hydrocarbons, or similar solvents. This polymer surfactant contains strong polar groups such as nitrogen (N) and oxygen (O), making it free from phosphorus (P), chloride (Cl), metals, and other toxic substances. The product is environmentally friendly, exhibits excellent oil solubility, and is thermally stable with a decomposition temperature exceeding 500℃. RUN-129 forms a dense monomolecular or polymolecular adsorption film on metal surfaces, effectively preventing high-temperature naphthenic acid corrosion.

HLN-127-4 is a high-performance water-soluble corrosion inhibitor designed to enhance efficiency and reduce production costs for atmospheric and vacuum distillation devices. By concentrating the active corrosion inhibition components into a four-fold solution, the product combines multiple types of inhibitors to provide excellent protection against corrosion caused by sulfides and chlorides. The product forms a robust protective film on metal surfaces through physical adsorption and chemical coordination adsorption.

HLN-127 is a high-performance neutralizing corrosion inhibitor specifically designed for use in atmospheric and vacuum distillation units. It effectively mitigates corrosion caused by acidic substances such as HCl and H2S, as well as scale corrosion due to ammonium chloride (NH4Cl) and iron sulfide (FeS). This product combines organic amines, amphoteric imidazolines, gas-phase corrosion inhibitors, anti-emulsifiers, and dispersants, providing comprehensive protection for critical equipment in refining processes.

HLN-124-4 is a hydrogenation corrosion inhibitor formulated with organic amines, polymerization inhibitors, cycloalkyl amphoteric imidazolines, morpholine derivatives, dispersants, and other corrosion inhibition components. This product leverages the synergistic effects among different types of inhibitors to form a protective film on metal surfaces through physical adsorption and chemical coordination adsorption. It provides excellent corrosion resistance, particularly in systems with high concentrations of sulfides, and effectively reduces the oxidation of sulfides to elemental sulfur, preventing under-scale corrosion.

HLN-124 is a patented, water-soluble hydrogenation corrosion inhibitor composed of multiple adsorption-type corrosion inhibitors, polycarboxylic acid polymer scale dispersants, organic amines, anti-emulsifiers, and acid corrosion inhibitors. The product is specifically designed for use in hydrocracking, hydrofinishing, and catalytic reforming processes to control ammonium bisulfide (NH4HS) erosion, fouling, and wet hydrogen sulfide (H2S) corrosion. It provides the following key benefits:

HLH-107 is a patented corrosion and scorch inhibitor (Patent No: ZL 201110203220.0) specifically designed for lubricating oil furfural refining units. It addresses the dual challenges of corrosion and coking, offering a comprehensive solution to extend equipment lifespan and improve operational efficiency. This product neutralizes furoic acid, prevents furfural oxidation, and reduces furfural condensation reactions, thereby mitigating corrosion and coking issues that are common in the industry.
