Source factory production site·real product shots
Self-built Songzi production base, independent research and development, independent synthesis, non-OEM and non-agency
Based on the petrochemical industry, we focus on independent research and development and synthesis of imidazoline corrosion inhibitors and heavy oil refined products, and supply them directly from the source factory.
In-house synthesis process · 20+ real application cases in refineries · Rapid sample inspection
The imidazoline corrosion inhibitor series has been stably supplied to many refineries at home and abroad; the heavy oil refining series helps refineries improve oil quality
Atmospheric and vacuum · Catalytic cracking · Hydrogenation · Oilfield gathering and transportation Full-scenario anti-corrosion solution
Non-hydrogenation complexation denitrification · Improves FCC feed quality · Basic nitrogen removal ≥80%
In an industry with fierce price competition, we choose to speak with technology and cases
The self-built Songzi factory has 10+ enamel/stainless steel reaction synthesis kettles of different specifications, and independently synthesizes imidazoline monomers, with complete quality inspection records for each batch. Direct supply from the source factory means transparent prices, traceable quality, and stable batches.Understand the production strength of the source factory →
A team of more than 10 experts continues to deepen expertise in petrochemical corrosion protection, oil product denitrification, and sewage reuse. Independent processes and proprietary formulas—not simple blending.View production capability →
State-owned refineries and large independent refining companies alike have practical application cases with our products. Test reports from third-party authoritative organizations can be provided, and the data speaks for itself before purchasing if qualified.

Low-acid-value denitrification of coker gas oil: basic nitrogen reduced from 1136/1585 μg/g to 429.8/772.5 μg/g at ~1.0-1.1% dosage.
Application reportErchang's phosphorus-free high-temperature corrosion inhibitor was successfully tested and significantly inhibited naphthenic acid corrosion in high-temperature areas, which was verified by scale sample analysis by the client group research institute.
application reportComplexation denitrification project for coker gas oil: non-hydrogenation tank-settling process reduces basic nitrogen and improves FCC feed quality.
Project proposalOn August 27, 2026, Hubei Benxin Environmental Protection Technology completed the full relocation of its production base to Songzi Port Industrial Park, Hubei Province. The new base is equipped with 10+ sets of enamel/stainless-steel reaction synthesis kettles, continuing the process route of synthesizing imidazoline in-house through high-temperature dehydration condensation of oleic acid and organic amines. The Wuhan Optics Valley R&D headquarters remains unchanged, with R&D and production now running in parallel.
In June 2026, at the invitation of a Shandong refinery, our team completed a scale-up deacidification trial on its No.2 atmospheric side-cut at the client's R&D centre, producing high-purity naphthenic acid samples as feedstock for downstream refining.
In May 2026, Benxin won the tender to supply the denitrification agent for a CNPC refinery's coker gas oil unit, helping keep the unit running stably, lowering basic nitrogen in the gas oil and improving feedstock quality.
BXH-102 The overseas export order of oil-soluble imidazoline stock solution was delivered on schedule, and the product quality was accepted by the customer.
Provide product specifications, third-party testing reports, and support laboratory evaluation. Quick sample delivery, usually arrives in 3-5 working days.
