A Shandong petrochemical enterprise deployed a customised 60 m³/h high-standard purification unit built on the JY-DL60 platform as the final step of its in-plant production process — finished diesel is filtered before it enters the plant's storage tanks, so every batch held and dispatched meets the same verified clarity.
A Shandong petrochemical enterprise deployed a customised 60 m³/h high-standard purification unit built on the JY-DL60 platform as the final stage of its in-plant production process. Finished diesel is filtered before it enters plant storage, so every batch held and dispatched meets the same verified clarity at full production speed, without turning the quality barrier into a process bottleneck.
A petrochemical company in Shandong — China's refining heartland — integrates refining, high-end chemicals and logistics storage in one large modern enterprise. Its high-standard diesel supplies major industrial and mining companies, logistics fleets and premium retail markets, with shipment volumes among the region's highest.
The company deployed a customised 60 m³/h high-standard outbound purification unit built on the JY-DL60 platform as the final step of the production process — after filtration, the finished diesel enters the plant's storage tanks, and quality is locked in before the fuel ever leaves the process side.

The company's competitive position rests on "quality and environmental standards" — in a market where diesel is heavily commoditised, its high-standard product commands industrial, logistics and premium retail customers who verify what they buy.
For an enterprise of this scale, outbound quality is not a laboratory abstraction: every batch that enters the storage tanks carries the brand's reputation — ultimately to a customer who can see haze, measure cleanliness and file a claim.
Guarantee finished-diesel cleanliness before it enters plant storage — at 60 m³/h full production speed, without turning the quality barrier into a process bottleneck.
A customised 60 m³/h outbound purification unit engineered around four mutually reinforcing safeguards.
Installed as the final step of the in-plant production process, the unit filters every batch of finished diesel before it enters the plant's storage tanks — pipeline debris and contaminants are intercepted before they can ever reach storage.
The membrane filter elements in this system have not been replaced since commissioning in 2025 — the unit has remained in continuous normal operation on the original membrane set, maintained through gas-pulse regeneration.
Built on the JY-DL60 platform — see the product page for full technical specifications.
Since commissioning, the system has performed as intended — results below as reported in the customer's project records.
| Indicator | Before (Typical) | After (Reported) |
|---|---|---|
| Fuel appearance | Slightly cloudy, visible suspended matter | Clear and bright |
| Mechanical debris | Visible rust and metal particles | None |
| Process efficiency | Frequent stoppages from blinded elements | Stable continuous full-load operation |
| Pressure-drop control | Rapid rise at high flow | Low initial drop, stable throughout |
| Cleanliness compliance | Variable at storage intake | Stable, national-standard compliant |
| Customer quality complaints | Occasional fuel-quality disputes | Markedly reduced |
Data note: outcomes on this page are drawn from the customer's project records (Case DS38, 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.
"We treat quality as our lifeblood. Jingyuan's 60 m³/h filtration system ensures our outbound diesel meets the cleanliness standards of modern engines. It has not only simplified quality control at the final production stage — it has strengthened our competitiveness in premium fuel supply. Every tanker of diesel that leaves this plant can stand on its own."
— Operations Manager, petrochemical company, Shandong
For large fuel suppliers, the final production step is where product quality is locked in — this project shows how that barrier can be made reliable without slowing production.
High flow and high precision are not a trade-off when the barrier is engineered for both — every batch enters storage verified, without waiting.
