Case Study
Stage 1 · Customer Problem
📋 Customer Problem
A Shandong Refining Co., Ltd. is located in an important energy and chemical base in China. As a large-scale enterprise integrating refining and chemical operations, its finished fuel is mainly supplied to transportation and industrial enterprises in surrounding provinces and cities. At the storage and transport terminal of this large refinery, ensuring clean dispatched fuel faces practical challenges:
🦠
Pipeline Rust Debris
The pipeline from the main storage tank to the loading bay is relatively long. Metal particles spalling from the pipe wall (such as rust) affect the normal operation of precision injector nozzles in downstream vehicles.
🛢️
Storage Tank Bottom Sediment
Large-scale refinery storage tanks generate sediment at the bottom during long-term operation. At high loading flow rates, this is easily drawn into the main flow, affecting the finished fuel appearance.
⚡
High-Load Loading Pressure
There is significant queuing pressure at the loading zone. The filtration system must complete high-precision purification without sacrificing flow rate (60m³/h), and must possess high system stability.
🚗
Downstream User Demands
With the widespread adoption of HPCR engines, downstream fleets' attribution of "black smoke, insufficient power, injector seizure" issues often points to refinery fuel quality, urgently requiring a solid quality barrier.
Stage 2 · Fuel Analysis · NEW
🔬 Fuel Analysis
Fuel sampling at the loading bay revealed contamination from long pipeline transport and storage tank bottom sediment, characteristic of large-scale refinery operations:
| Metric | Before Treatment | After Treatment | Improvement |
|---|
| ISO 4406 Cleanliness | ~22/20/17 | 14/12/9 | 3 levels ↑ |
| Free Water (ppm) | ~160 | ≤50 | 69% ↓ |
| Visual Appearance | Cloudy, rust-visible | Clear, transparent | — |
| TAN (mgKOH/g) | 0.13 | 0.07 | 46% ↓ |
| Particle Composition | Iron oxide (rust), tank bottom sediment, scale | ≥98% removed at ≥5 μm | 98% ↓ |
Values are representative based on site conditions (long pipeline from storage tank to loading bay, high-flow loading operations). On-site laboratory data confirmed the filtered diesel cleanliness achieved ISO 14/12/9 standards, effectively resolving pipeline secondary contamination issues.
Stage 3 · Solution
🛠️ Solution & System Configuration
Jingyuan provided the enterprise with a dual-stage high-flow purification solution. A 60m³/h and 40m³/h combination configuration covers different loading arm flow rates, achieving "load and purify simultaneously." The system is equipped with high-contaminant-capture-capacity precision cartridges, effectively extending the cartridge replacement cycle while ensuring micron-level filtration precision.
Model
JY-DL60 + JY-DL40 (Dual Config)
Membrane
Polymer Rigid Composite, 5 μm nominal
β Value
≥200 at rated pore size
Operating Pressure
0.2–0.4 MPa
Regeneration
Gas-pulse regeneration (brief 5-15 min safety pause)
Explosion-Proof
Ex d IIB T4
Cartridge Capacity
High-contaminant-capture design
Key design decisions: The oleophilic-hydrophobic membrane material efficiently intercepts particulate impurities while synergistically removing trace free water, ensuring dispatched fuel is clear and transparent. The dual-configuration design matches different loading arm flow rates without sacrificing speed. The entire system strictly follows petrochemical industry explosion-proof and static electricity protection standards, ensuring safe operation in flammable and explosive zones.

By deploying these two customized systems, the enterprise effectively improved the cleanliness of dispatched diesel. At a high flow rate of 60m³/h, the system demonstrated good differential pressure control capability without affecting loading speed. On-site laboratory data shows the filtered diesel cleanliness achieved ISO 14/12/9 standards, effectively resolving pipeline secondary contamination issues. This not only improved the enterprise's quality control image but also provided reliable quality assurance for downstream distributors.
Stage 5 · Lessons Learned · NEW
💡 Lessons Learned
✅
Key Success Factor
The dual-configuration (60+40m³/h) design was the critical decision. By matching different loading arm flow rates with appropriately sized units, the refinery achieved "load and purify simultaneously" without any logistics bottleneck, ensuring high-precision purification at full loading speed.
⚠️
Common Pitfall
Many refineries treat loading bay filtration as an afterthought, relying on storage tank settling alone. This approach fails at high loading flow rates, where tank bottom sediment is drawn into the main flow. Single-stage or undersized filters also cannot handle the contaminant load from long, aging pipelines.
🔄
Replication Advice
Directly applicable to all large-scale refinery loading stations with long pipeline runs and high dispatch volumes. The dual-configuration approach can be scaled by adding more units in parallel for stations with multiple loading arms. The high-contaminant-capture cartridge design is particularly valuable for facilities with aging pipeline infrastructure.
