CorFix™ 9113 Corrosion Inhibitor
Refinery Corrosion Inhibitors: Filming & Neutralizing Amine-Based Cl
CorFix™ 9113 Corrosion Inhibitor
Protecting Refinery Lines from Corrosion
In oil refineries, corrosion poses a significant operational challenge, intensified by high temperatures, fluctuating pressures, and acidic crude oils containing naphthenic acids, H₂S, and CO₂. CorFix™ 9113 is specially engineered to perform under these demanding conditions, delivering reliable and continuous protection across diverse refinery processes. Its phosphate-free formulation effectively inhibits naphthenic acid corrosion, forming a protective barrier on metal surfaces that repels water and minimizes corrosion reactions. Optimized for both high- and low-temperature environments, CorFix™ 9113 safeguards condensers, condensate systems, and other critical equipment, ensuring enhanced operational efficiency, equipment longevity, and refinery integrity.
Performance Highlight
Preventing naphthenic acid corrosion in refineries
CorFix™ 9113 delivers exceptional protection against high-temperature naphthenic acid corrosion in refinery units. In crude oils with a total acid number (TAN) of 3 mg KOH/g at 300 ºC, achieving up to 99% inhibition and reducing corrosion rates from 221 to 2 mpy, it forms a durable, thermally stable film that safeguards metal surfaces and ensures reliable operation with reduced maintenance and downtime.
| CorFix™ 9113 Concentration (ppm) | Corrosion Rate (mpy) | Corrosion Inhibition (%) |
|---|---|---|
| 0 | 221 | NA |
| 300 | 74 | 67 |
| 500 | 28 | 90 |
| 700 | 2 | 99 |
Engineered for Reliable High-Temperature
Provides robust corrosion inhibition for critical refinery equipment such as distillation columns, heat exchangers, and transfer lines under high-temperature conditions (>250 °C).
Phosphorus-Free Formulation
Applicable in downstream refinery units without the negative effects of phosphate-based corrosion inhibitor.
Lower Maintenance and Operational Costs
Maintains cleaner metal surfaces, extends inspection and turnaround intervals, and minimizes repair, cleaning, and replacement requirements. Optimizes overall refinery efficiency and cost-effectiveness.
