A Shandong new-energy company deployed a dedicated JY-DX40-based 40 m³/h purification unit beside its product tanks — intercepting micron-scale gum and oxidised resin that conventional mechanical filters cannot catch, turning slightly hazy diesel into a clear, high-grade product.
A Shandong new-energy company deployed a dedicated JY-DX40-based 40 m³/h purification unit beside its product tanks, intercepting the micron-scale gum and oxidised resin that conventional mechanical filters cannot capture. The unit runs in circulation mode during non-loading periods, upgrading tank-held diesel from hazy to clear without becoming a logistics bottleneck.
A new-energy company in Shandong Province — a refining and clean-energy petrochemical producer supplying high-standard diesel to precision industrial equipment and premium transport markets — deployed a customised 40 m³/h diesel purification unit built on the JY-DX40 platform at its product-tank area.
Installed beside the main storage tanks, the unit operates in circulation mode during non-loading periods — continuously upgrading the quality of tank-held product — and in dispatch mode for outbound purification. The result: "polish while you store", with product diesel kept clear and bright around the clock.

The customer is a petrochemical enterprise focused on finished-oil refining and clean-energy development — a production-grade operation with extremely high quality standards, supplying diesel for high-precision industrial equipment and premium transport applications.
In the refined-fuel business, clarity is quality. Trace contamination and gum do not merely affect appearance — they directly determine product grade, and in premium tenders a hazy sample is a scoring liability that no sales team can talk around.
Supply high-standard, visually clear diesel to premium markets — and do it at refining throughput, without turning purification into a logistics bottleneck.
Jingyuan deployed a dedicated refining-grade purification system — protecting finished-product quality across three dimensions.
The "polish while you store" operating concept is the heart of this deployment: instead of treating fuel only at the loading moment, the system continuously circulates tank contents during storage — so product quality is upgraded in the tank, not just at the gate.
Built on the JY-DX40 platform — see the product page for full technical specifications.
The system delivered a complete loop from product-quality improvement to commercial return, as reported by the customer.
| Indicator | Before (Typical) | After (Reported) |
|---|---|---|
| Appearance | Slightly hazy, visible suspended matter | Clear and bright |
| Fine gum | Above target range | Markedly reduced |
| Mechanical debris | Trace visible particles | None |
| Chemical additive dependency | Relatively heavy use | Reduced usage |
| Premium-market competitiveness | Limited | Significantly improved |
Data note: qualitative outcomes on this page are drawn from the customer's project records (Case DS13, updated 2025) and are presented as reported. They describe this deployment and are not a general performance guarantee — actual results depend on feed condition and plant configuration.
"In the new-energy industry, clarity equals quality. The fine gum in our diesel used to be a technical problem — until we installed Jingyuan's 40 m³/h system. It gives our product the final 'polish' it needed. Our diesel is now clear and bright, meeting the demands of the premium market."
— Production Director, new-energy company, Shandong
The value of this project is the shift from end-of-pipe treatment to source-level quality control — purity engineered into the product before it ever ships.
For refiners and quality-focused fuel producers, membrane-grade purification at the tank turns fuel clarity from a tender liability into a verifiable product advantage.
