Oil Treatment Agent Series
  • ZHQ-AT-01 Fatty Acid Type Diesel Anti-wear Agent

    ZHQ-AT-01 Fatty Acid Type Diesel Anti-wear Agent is a high-efficiency diesel anti-wear agent mainly composed of various fatty acids. It effectively compensates for the degraded lubricity of diesel caused by desulfurization and refining. A small dosage can greatly improve diesel lubricity and anti-wear performance, and effectively reduce wear on relevant engine components.The product can be diluted with diesel or added directly to diesel, featuring easy uniform blending, high flash point and safe, convenient application. It burns completely along with diesel to form harmless substances and causes no pollution to the environment.

  • ZHQ-AT-02 Fatty Acid Type Diesel Anti-wear Agent

    ZHQ-AT-02 fatty acid ester type diesel anti-wear agent is a low-acid product mainly composed of multiple fatty acid esters. It can effectively improve the lubricity of desulfurized refined diesel and enhance the anti-wear performance of low-sulfur diesel. A small dosage can greatly optimize the lubricating property of diesel and prevent wear of relevant engine components.

  • ZHQ-AA-01 Gasoline and Diesel Antistatic Agent

    ZHQ-AA-01 Gasoline & Diesel Antistatic Agent is specially developed to prevent static electricity generation during the transportation, loading and unloading of fuel oils. Rapid flow of fuels tends to accumulate large amounts of static charges, which poses potential safety hazards. After addition of this antistatic agent, accumulated static charges can be safely dissipated via grounding to eliminate explosion risks.This product is widely applicable to light oils and heavy fuels including naphtha, gasoline, diesel oil and heavy oil, and can effectively improve the antistatic performance of oil products.

  • ZHQ-PPD-01 Diesel Pour Point Depressant

    ZHQ-PPD-01 Diesel Pour Point Depressant can rapidly lower the freezing point of diesel oil, effectively refine wax crystals and reduce cold filter plugging point, so as to greatly improve the low-temperature fluidity of oil products. It is non-toxic, non-corrosive and features good flowability.

  • ZHQ-LTNI-01 Neutralization Corrosion Inhibitor

    ZHQ-LTNI-01 Neutralization Corrosion Inhibitor

  • ZHQ-PR01 Crude Oil Demulsifier

    TH-PR series crude oil demulsifiers are alkyl oxide resin type products. They can effectively neutralize emulsifying media, enabling fine water droplets dispersed in crude oil to coalesce, grow larger and settle down, while the oil phase quickly rises to the top.

  • ZHQ‑DCa Crude Oil Calcium Remover

    ZHQ-DCa crude oil decalcifier is a water-soluble agent mainly composed of small-molecule polymeric carboxylic acid, chelating agent and corrosion inhibitor. It can react with calcium ions in crude oil to form stable water-soluble chelates. Through chelation and precipitation, calcium ions are converted into water-soluble substances or water-phase sediments, which are removed along with the water phase during oil-water separation in electric desalting units.

  • Model ZHQ-LTIC-01 Corrosion Inhibitor for Top of Atmospheric & Vacuum Distillation Column

    Model ZHQ-LTIC-01 Corrosion Inhibitor for Top of Atmospheric & Vacuum Distillation Column

  • ZHQ-HTIC-01 High Temperature Corrosion Inhibitor

    ZHQ-HTIC-01 High Temperature Corrosion Inhibitor is a high-efficiency film-forming oil-soluble corrosion inhibitor. It can directly protect corroded areas and form a firm chemical protective film.

  • ZHQ-SIS-01 Slurry Antiscaling Agent

    ZHQ-SIS-01 Oil Slurry Antiscaling Agent is an oil-soluble antiscalant mainly composed of detergent dispersant, antioxidant and polymerization inhibitor.After adding this product, the detergent-dispersant components can prevent the agglomeration and deposition of corrosive products, inorganic salts and organic polymer particles in feedstock, thus reducing the formation of inorganic scale.
