Case Study
A Shandong Petrochemical Co., Ltd. is located in Shandong, an important energy hub in China. As a large-scale modern petrochemical enterprise integrating refining, high-end chemicals, and logistics storage and transport, the company's core competitiveness lies in "premium quality and environmental protection." Its high-standard diesel is widely supplied to large-scale industrial and mining operations, logistics companies, and the high-end retail market.
Stage 1 · Customer Problem
Refinery Dispatch Quality Control Challenges
As a large-scale finished fuel supplier, the enterprise faces demanding quality control tests at the dispatch stage. High-load loading operations stress pipelines and filters simultaneously, threatening both throughput and fuel cleanliness.
🏭
Pipeline Secondary Contamination
The refinery's extensive pipeline network generates micron-level metal debris and rust during long-term operation, which easily enters tanker trucks during loading, affecting the customer experience.
🛢️
Storage Tank Bottom Sediment
Large storage tanks generate sediment at the bottom during long-term operation. If not effectively treated before loading, it affects the fuel appearance.
⚡
High Flow vs. High Precision Balance
The loading bay requires 60m³/h throughput. Standard filters often experience rapid pressure drop increase at high flow, causing frequent cartridge blockage and affecting loading efficiency.
🏆
Brand Reputation Assurance
In a diesel market with severe homogenization, the enterprise needs to prove its high-quality commitment to customers through the visualized means of "physical purification."
Stage 2 · Fuel Analysis · NEW
Pre-Filtration Fuel Condition Assessment
Sampling at the loading arm revealed contamination levels exceeding National VI cleanliness requirements, driven by pipeline rust and tank-bottom entrainment under high-flow draw.
| Indicator | Before Filtration | After Filtration | National VI Target |
|---|
| ISO 4406 Cleanliness | 21/19/16 | 15/13/10 | ≤18/16/13 |
| Free Water (ppm) | 180 | 35 | ≤50 |
| Visual Appearance | Hazy with visible particles | Clear & transparent | Clear & bright |
| TAN (mgKOH/g) | 0.18 | 0.11 | ≤0.10 |
| Particle Composition | Iron oxide & metal fines | <4µm organic only | No hard metal particles |
Iron-rich particles confirmed pipeline rust as the primary contamination source under 60m³/h high-load loading.

Stage 4 · Results
Dispatch Quality & Operational Performance
| Metric | Before Deployment | After Deployment |
|---|
| Pressure drop rise | Rapid at 60m³/h, frequent blockage | Stable, gas-pulse regeneration sustains flow |
| Cartridge life | Short, frequent replacement | Significantly extended |
| Loading time | Extended by blockage downtime | No increase, full-load maintained |
| Visual clarity | Hazy with particles | Clear & transparent |
| Downstream acceptance | Quality disputes from pipeline impurities | No complaints reported |
The 60m³/h throughput effectively matches the dispatch bay's operational rhythm, significantly improving diesel visual clarity and particle count indicators without increasing loading time.
Stage 5 · Lessons Learned · NEW
Key Takeaways from 60m³/h Refinery Loading
✅
Parallel High-Flow Skid Architecture
A large-volume parallel filter housing design is essential to sustain 60m³/h full-load operation with stable internal flow velocity and low initial pressure drop, avoiding the rapid clogging seen with standard single-cartridge filters.
⚠️
Pipeline Rust Must Be Intercepted Progressively
Refinery pipeline iron oxide and metal fines are the dominant contamination source under high-load loading. Progressive layered cartridges are required to intercept micron-level solid impurities and protect downstream HPCR injection systems.
🔄
Gas-Pulse Regeneration Sustains High-Flow Stability
Gas-pulse group-switching regeneration is critical for maintaining cartridge capacity during continuous high-flow dispatch. Combined with DCS-interlocked differential pressure monitoring, it enables digital management of cartridge life without interrupting loading rhythm.
