Where it is used

  • ⚙️ Refinery overhead systems: Protection against wet H₂S corrosion
  • ⛽ Oilfield gathering & injection water lines: Protection against H₂S, CO₂ and high-salinity water corrosion
  • 🏭 Industrial cleaning / pickling: 0.1-0.5% concentration as pickling inhibitor to protect base metal
  • 🔩 Electroplating: Process corrosion inhibition for electroplating
  • 💧 Circulating water systems: Corrosion control to extend heat exchanger life

Product advantages

✔ The imidazoline head group is strongly adsorbed on the metal surface, and the corrosion inhibition efficiency is >85% (coupling test)
✔ Good water solubility, easy to add, does not affect the quality of downstream products
✔ Good compatibility with demulsifiers, neutralizing amines and other additives
✔ In-house lab with three-checkpoint QC: raw material, in-process and finished goods, batch report issued

Typical applications

A CNPC Refinery Atmospheric and Vacuum Unit
CNPC · A Certain Refinery

BXH-101 injected into overhead wash water (5-20 ppm on feed basis) as part of the standard desalting-and-injection anti-corrosion program, controlled to condensate Fe²⁺ ≤1 mg/L and pH 5.5-6.5, with coupon-tested inhibition efficiency >85%.

BXH-101/102 are our flagship export concentrates: multiple export orders delivered on schedule since 2025, with overseas customers verifying quality through their own formulation programs.

Industrial cleaning & metalworking
A domestic refinery

At 0.1-0.5% concentration, used as a pickling inhibitor for equipment and workpieces, in electroplating processes and for inter-process rust prevention of machined parts — a mature application field beyond refineries.

FAQ

How do BXH-101 and BXH-102 work together?
Both target aqueous phase (water-soluble) and oil-phase (oil-soluble) environments respectively. In the atmospheric and vacuum tower top system, BXH-101 is usually used to inject wash water first to protect the most severely corroded gas-liquid interface, and then cooperate with BXH-102 to inject circulating oil to protect the distillate pipeline. The ratio between the two is dynamically adjusted based on the water content and corrosion data of the unit.
What is the minimum purchase quantity? Can I make a sample first?
The official minimum purchase quantity is 200 L (one barrel). New customers can apply for 100-500ml free technical samples for coupon testing or on-site pilot evaluation. Fill out the contact form to arrange delivery without committing to a purchase quantity.
Is there a third-party testing report?
Yes, we hold more than 10 evaluation reports issued by third-party organizations such as the Petrochemical Research Institute and China Petrochemical Research Institute, covering indicators such as corrosion inhibition efficiency, compatibility with compatible chemicals, and environmental toxicity. Sales engineers can be contacted to provide it on demand.
