Metalworking · oil & gas gathering industries

Beyond refineries, BXH-102 is widely used for rust prevention of machined parts, metalworking fluid formulations and oil & gas gathering pipeline protection, and serves as an intermediate for downstream formulators.

FAQ

How to select oil-soluble imidazoline corrosion inhibitor? What is the difference between oil-soluble and water-soluble?

The core of selection depends on the phase state of the medium where corrosion occurs: if the corrosion is in the oil phase (inner wall of crude oil pipeline, oil phase stratification interface), select oil solubility (BXH-102); if the corrosion is in the water phase (water-containing cutting fluid), select water solubility (BXH-101). BXH-102 forms a hydrophilic and oleophobic film on the pipe wall after being dissolved in crude oil, blocking the erosion of corrosive water molecules and Cl⁻.

Which corrosion inhibitor should be chosen for crude oil pipelines? How much to add?

For long-distance crude oil pipelines, BXH-102 oil-soluble imidazoline is recommended, with an injection volume of 10–30 mg/L (based on the transmission volume). For high flow rate (>3 m/s) scenarios, it is recommended to upgrade to BXH-105 enhanced type, which has faster film formation speed and stronger erosion resistance.

How to choose corrosion inhibitors for oilfield gathering and transportation pipelines?

Oilfield gathering and transportation pipelines need to pay attention to the moisture content: if the moisture content is <60%, choose BXH-102; if the moisture content is >60%, choose OEM (anti-emulsification type), which has a lower emulsification tendency and does not affect subsequent dehydration treatment.

Can BXH-102 be exported? What certifications are there?

BXH-102 has completed the chemical export registration with the Ministry of Commerce and has export qualifications. Products have been exported to many countries and regions in Southeast Asia and the Middle East. For export procedures, please contact our International Business Team.

In-depth analysis: BXH-102 Oil-soluble imidazoline intermediate

Three core application scenarios of oil fields, pipeline transportation and refineries

Oil-soluble imidazoline corrosion inhibitor is one of the most widely used corrosion inhibitor categories in the petrochemical and oil fields. BXH-102 dissolves the imidazoline active component in an organic solvent carrier, injects it into an oil phase medium, and then disperses on its own. It competitively adsorbs on the metal surface, displaces the adsorbed corrosive water molecules, and forms a hydrophobic protective film.

Compared with water-soluble corrosion inhibitors, BXH-102 is more suitable Pipelines with low crude oil moisture content (<40%), Refining unit circulating oil injection point and Anti-corrosion protection of tank bottom. For oilfield conditions with high water content (>60%), it is recommended to use OEM anti-emulsification type.

Comparison of keywords for oil-soluble corrosion inhibitor selection

Crude oil pipeline corrosion inhibitor

BXH-102 forms a film on the pipe wall after being dissolved in crude oil, effectively preventing pitting corrosion and uniform corrosion of carbon steel after HCl and H₂S are dissolved in water in the pipe.

Imidazoline derivatives antiseptic

BXH-102 belongs to the quaternary ammonium salt derivative of amido imidazoline. Through the cooperative adsorption of N atoms and alkyl chains, the film formation is denser and the temperature resistance is better than ordinary imidazoline.

Refining unit circulating oil injection

The circulating oil at the top of the atmospheric and vacuum tower is injected into BXH-102 to protect the distillate pipeline and heat exchanger at the oil-water interface, forming a double-layer protection with BXH-101 water phase protection.

CO₂/H₂S Corrosion Protection

BXH-102 is effective against H₂S·CO₂·organic acid corrosion. It is suitable for high-acid crude oil processing equipment and has passed the sour crude oil evaluation test.
