Our own Songzi production base — developed and synthesized in-house, not toll-manufactured, not resold
We synthesize corrosion inhibitor concentrates in-house and deliver complete heavy-oil refining process packages — direct from our own plant.
In-house synthesis · Three-checkpoint QC in our own lab · 20+ refinery applications · Fast sampling
Our corrosion inhibitor concentrates are in service at refineries, oilfields, water-treatment plants and metalworking shops in China and overseas. Our heavy-oil packages — denitrification, deacidification and slurry deashing — lift refinery feedstock quality.
Refineries · Oilfields · Water treatment · Metalworking — corrosion protection across the board
Non-hydrogenation · Denitrification / deacidification / deashing · Delivered as a complete package
In an industry that competes on price, we would rather compete on data
Our Songzi plant runs 10+ glass-lined and stainless-steel reactors in a range of sizes, and synthesizes the imidazoline monomer itself. Every batch carries a full QC record. Buying from the plant that made it means transparent pricing, traceable quality and batch-to-batch consistency.See our production capability →
A team of 10+ specialists working on refinery corrosion protection, oil denitrification and wastewater reuse. Our own process, our own formulas — not off-the-shelf blending.View production capability →
Both state-owned refineries and large independent refiners run our products in production. We can supply third-party test reports up front — check the data, then buy only once it passes your own evaluation.

Rooted in state-owned refineries, expanding overseas, and working closely with our trading partners
Repeat shipments of oil-soluble and water-soluble imidazoline concentrate to the Middle East and West Africa, used in oilfield gathering systems, with a high reorder rate.
Customer reportSuccessfully applied on the No.2 atmospheric distillation unit, markedly suppressing naphthenic acid corrosion in the high-temperature sections — and, critically, resolving the reactor fouling that phosphorus-based inhibitors had been causing in the downstream hydrotreater.
Application reportOur complete coker gas oil denitrification process has run here for years, cutting basic nitrogen in the coker gas oil down to the typical level of vacuum gas oil.
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 reactors, 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 center, 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 concentrate was delivered on schedule, and the product quality was accepted by the customer.
We supply the product specification and third-party test reports, and support your own lab evaluation. Samples usually arrive within 3–5 working days.
Serving state-owned refiners including Sinopec, CNOOC and PetroChina, plus 20+ large independent refining and chemical companies
