HLN-124 Hydrogenation Corrosion Inhibitor
Product Features
- Scale Inhibition: Forms water-soluble compounds with ammonium salts, preventing low-temperature precipitation and under-scale corrosion caused by NH4HS deposits.
- Corrosion Inhibition: Creates a dense and stable protective film on metal surfaces, mitigating NH4HS and wet H2S corrosion.
- Neutralization: Neutralizes condensed HCl and H2S, preventing acidic corrosion in equipment.
- Environmental Safety: Free of metals and harmful elements, does not react with sulfur-containing sewage, and has no adverse effects on oil-phase systems or subsequent products.

Applications
- Ammonium Bisulfide Corrosion Control: Mitigates NH4HS erosion and fouling in hydrogenation reactors and associated equipment.
- Wet Hydrogen Sulfide Corrosion Prevention: Protects overhead condensing cooling systems in refining units from wet H2S corrosion.
Usage Instructions
1. **Preparation:** Pump the product into a corrosion inhibitor storage tank and dilute with demineralized or softened water to the desired concentration.
2. **Injection Points:** Recommended for the condenser inlet at the top of the tower. Use DN15 stainless steel pipelines, ensuring the injection port extends to the pipeline center.
3. **Dosage:** Typical dosage ranges from 10μg/g to 30μg/g based on processing volume. Adjust according to the S, N, and Cl content in crude oil.
4. **Pre-Passivation:** During the initial 5 days, increase dosage to 30-50ppm to establish a solid protective film.
5. **Pipeline Maintenance:** Before switching corrosion inhibitor types, flush and purge injection pipelines thoroughly to prevent blockages.
