JY-DX40 System Powers Regional Depot Quality Upgrade
Diesel Purification (Multi-Depot Distributed Application)
Key outcomes
- Unified Quality: Achieving a high degree of uniformity in finished fuel quality across different oil depots
- Reduced Maintenance Costs: Effectively reduces the maintenance costs of depot transport systems
- High-Flow Efficiency: Single-unit 40m³/h high flow rate, without affecting loading/unloading vehicle efficiency
Case Study
Stage 1 · Customer Problem
📋 Customer Problem
A large-scale energy distribution enterprise in a West African country operates multiple key oil depots across its territory. The country's diesel is highly susceptible to secondary contamination throughout the supply chain (barges, tanker trucks, storage tanks), so the customer deployed professional filtration equipment at distribution stations in three core cities. Managing cross-regional depots exposed the following problems:
🔀
Quality Fluctuations Across Sources
Diesel quality from different sources (barges, trucks, tanks) varies significantly; end customers report inconsistent fuel cleanliness at different stations, damaging brand reputation.
🌡️
Hot-Humid Climate Contamination
Under hot and humid climate conditions, storage tanks are prone to microbial growth and particulate matter accumulation, with ISO particle counts often at a poor level of 24/22/19.
📊
Precision Metering Damage
Rust and hard particles in the fuel frequently damage digital flow meters on the loading line, causing repair costs and economic losses from metering errors.
🧹
Frequent Downtime Cleaning
Periodic cleaning of storage tank bottom sludge is required, affecting depot turnover rates and operational continuity.
Stage 2 · Fuel Analysis · NEW
🔬 Fuel Analysis
Fuel sampling at the depot loading points revealed contamination from secondary supply-chain handling and hot-humid storage conditions:
| Metric | Before Treatment | After Treatment | Improvement |
|---|
| ISO 4406 Cleanliness | ~24/22/19 | 15/13/10 | 3+ levels ↑ |
| Free Water (ppm) | ~220 | ≤50 | 77% ↓ |
| Visual Appearance | Cloudy, hazy | Clear, transparent | — |
| TAN (mgKOH/g) | 0.18 | 0.09 | 50% ↓ |
| Particle Composition | Rust, microbial debris, sand | ≥98% removed at ≥5 μm | 98% ↓ |
Values are representative based on site conditions (West African hot-humid climate, multi-source diesel via barges/trucks/tanks). Field testing confirmed visual clarity improvement and compliance with regional dispatch cleanliness standards.
Stage 3 · Solution
🛠️ Solution & System Configuration
Jingyuan deployed JY-DX40 high-flow purification systems at the loading pump group outlet of three oil depots. Selection logic: the 40m³/h single-unit flow rate matches loading-bay throughput without affecting vehicle loading/unloading efficiency, while the mobile/fixed dual-mode allows circulation purification of different storage tanks as needed.
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

Deployment
3 depots, mobile/fixed dual-mode
Key design decisions: The Jingyuan® polymer rigid composite membrane leverages oleophilic-hydrophobic properties to efficiently intercept particulate impurities while synergistically removing trace free water, ensuring dispatched fuel is clear, transparent, and meets cleanliness standards. Deep filtration technology enables a single unit to effectively intercept micron-level fine particles at a 40m³/h flow rate.

Calibration Cycle Extended
| Metric | Before | After | Improvement |
|---|
| ISO 4406 Cleanliness | ~24/22/19 | 15/13/10 | 3+ levels ↑ |
| Flow Meter Calibration Cycle | Quarterly | Annually | 4× longer |
| Dispatch Fuel Clarity | Cloudy, hazy | Clear and transparent | — |
| Tank Cleaning Frequency | Periodic sludge removal | Greatly reduced | — |
| Annual Consumable Cost | ~¥36,000 | ¥0 | 100% ↓ |
By deploying JY-DX40 across different oil depots, the customer achieved standardized fuel cleanliness across the entire region. Monitoring data shows that all stations' dispatched diesel stably remains within ISO 15/13/10. Due to the clean fuel, the downstream flow meter calibration cycle was extended from quarterly to annually, effectively reducing operating expenses and metering losses.
Stage 5 · Lessons Learned · NEW
💡 Lessons Learned
✅
Key Success Factor
Standardized multi-depot deployment with mobile/fixed dual-mode was the critical decision. Uniform JY-DX40 units at every loading point ensured consistent quality across all stations regardless of diesel source, protecting brand reputation and enabling true regional quality control.
⚠️
Common Pitfall
Many regional distributors treat each depot independently with reactive cartridge replacement, which is costly, labor-intensive, and unable to guarantee consistent cleanliness across sources. Cross-regional quality consistency requires unified membrane filtration with gas-pulse sequential regeneration to eliminate reactive maintenance entirely.
🔄
Replication Advice
Directly applicable to multi-depot distribution networks in tropical and humid regions (Southeast Asia, Sub-Saharan Africa, Latin America) where secondary supply-chain contamination is severe. For depots requiring higher throughput, multiple JY-DX40 units can be deployed in parallel with synchronized group-switching regeneration.

Customer feedback
Distributing JY-DX40 units across each station was one of the right decisions we made this year. It not only protects precision pumps and valves but, more importantly, provides customers with quality-stable fuel. Now our stations are locally recognized as synonymous with high-quality diesel.
