Case Study
Stage 1 · Customer Problem
📋 Customer Problem
A Northeast Oilfield operates a vast finished fuel storage and transport network, with multiple depots of different scales and construction eras under its jurisdiction. These depots jointly undertake the diesel supply task for the surrounding area and the Northeast region, serving as an important component of regional energy logistics. When managing dispersed multiple oil depots, the customer faced the pain point of "inconsistency" across its network:
🏗️
Large Differences in Depot Conditions
Different oil depots were built in different years. Aging depots suffer from severe pipeline corrosion, while newer depots face impurity issues during the new tank break-in period, causing inconsistent dispatched fuel quality.
📊
Difficulty Unifying Quality Control
Previously, each depot used different brands of filters with varying precision, causing downstream logistics fleets to frequently complain that fuel from a specific depot was not as clean as from others.
🔧
Complex Maintenance Management
Diverse equipment models made spare parts inventory (cartridges, seals) cumbersome, increasing procurement and management costs across the depot network.
🚛
Shipping Efficiency Bottleneck
All oil depots face queuing pressure during peak dispatch periods, urgently requiring a standardized solution that guarantees both 60m³/h flow rate and unified precision.
Stage 2 · Fuel Analysis · NEW
🔬 Fuel Analysis
Fuel sampling across the 6 depots revealed significant quality variance driven by differing infrastructure ages and filter brands. The unified baseline target was set at ISO 14/12/10 for all dispatched diesel:
| Metric | Before Treatment | After Treatment | Improvement |
|---|
| ISO 4406 Cleanliness | ~22/20/17 to ~24/22/19 (varies by depot) | 14/12/10 (all stations) | 3–4 levels ↑ |
| Free Water (ppm) | ~200 | ≤50 | 75% ↓ |
| Visual Appearance | Inconsistent (cloudy at aging depots) | Clear, transparent (all stations) | — |
| TAN (mgKOH/g) | 0.14 | 0.08 | 43% ↓ |
| Particle Composition | Iron oxide, pipeline scale, break-in debris | ≥98% removed at ≥5 μm | 98% ↓ |
Values are representative across 6 depots with varying infrastructure conditions (aging pipelines at older depots, new-tank break-in at newer depots). Post-treatment results confirm all stations achieved the unified ISO 14/12/10 baseline.
Stage 3 · Solution
🛠️ Solution & System Configuration
The customer adopted a "unified model selection, distributed implementation" strategy, procuring multiple sets of Jingyuan 60m³/h purification units. All equipment adopts unified specifications and interface design, achieving "plug-and-play" integration into existing loading arm systems. A unified cleanliness baseline (ISO 14/12/10) was set for the entire jurisdiction, and all stations may only dispatch after meeting the standard.

Deployment
6 stations, unified model
Key design decisions: The standardized modular design enables quick integration regardless of depot age or scale. The internal cartridge configuration offers good adaptability to different operating conditions, ensuring the same high-quality fuel output under varying conditions. Since all 6 stations use the same equipment model, the customer needs only one central spare parts depot, effectively reducing inventory backlog and cross-depot maintenance costs.

Central Spare Parts Depot
| Metric | Before | After | Improvement |

| Cross-Depot Quality Variance | Significant (3–4 ISO levels) | Zero (all at 14/12/10) | 100% unified |
| Spare Parts Inventory | Multiple brands, high stock | Single model, 1 central depot | — |
| Filter Replacement Cycle | Every 2–4 weeks (varies) | 0 (3-year membrane life) | 100% eliminated |
| Downstream Fleet Complaints | Frequent (depot-specific) | Eliminated | — |
| Peak Dispatch Throughput | Bottlenecked by old filters | 60m³/h sustained at all stations | — |
Through the distributed deployment of multiple units, the oilfield successfully narrowed the quality differences among its subordinate depots. Regardless of which sub-depot a tanker truck loads fuel from, the diesel cleanliness achieves ISO 14/12/10 standards. This "standardized replication" model not only improved the overall brand image but also effectively enhanced cross-depot equipment maintenance efficiency. The Jingyuan 60m³/h units have become a benchmark case for standardized depot upgrades in the region.
Stage 5 · Lessons Learned · NEW
💡 Lessons Learned
✅
Key Success Factor
The "unified model selection, distributed implementation" strategy was the critical decision. By standardizing all 6 stations on the same JY-DL60 platform with a single ISO 14/12/10 baseline, the oilfield eliminated cross-depot quality variance while simplifying spare parts management to a single central depot.
⚠️
Common Pitfall
Many multi-depot operators allow each depot to independently select filter brands and precision levels. This fragmented approach creates inconsistent dispatched fuel quality, frustrates downstream fleet customers, and multiplies spare parts inventory complexity. A unified standard is essential for network-wide quality control.
🔄
Replication Advice
Directly applicable to any multi-depot oilfield or regional fuel distribution network. The standardized modular design enables rapid deployment across depots of different ages and scales. For networks requiring higher flow rates, multiple JY-DL60 units can be deployed in parallel at high-throughput stations while maintaining the same unified baseline.

Customer feedback
Due to varying infrastructure conditions, managing the quality of multiple oil depots used to be a headache. By deploying Jingyuan 60m³/h units as standard equipment across 6 stations, we achieved unified quality output. Now, regardless of which depot the fuel comes from, the dispatched diesel all meets the same high standards.
