10m³/h Skid System & JY-219A Mobile Equipment Synergy Solution
Diesel Purification (Farm Large-Capacity Storage)
Key outcomes
- Large-Capacity Purification Capability: 10m³/h single-unit flow rate, meeting the rapid circulation and intake purification demands of large-capacity oil depots
- Full-Process Quality Control Coverage: Achieving full-process purification from "central fuel depot" to "field-side"
- Reduced Storage Tank Sludge Accumulation: Effectively reduces sludge accumulation at the storage tank bottom
Case Study
Stage 1 · Customer Problem
📋 Customer Problem
A modernized core farm in Northeast China operates an independent large-scale central fuel depot with high annual diesel turnover and multiple sub-farm work zones, with fleet scale and automation at a large-scale operational level. Before upgrading its filtration system, the farm faced dual pressure from "source contamination" and "secondary contamination":
🚚
Inconsistent Bulk Intake Quality
Diesel delivered by external tanker trucks often contains residual rust and impurities from transport pipelines; direct loading contaminates the entire tank of fuel.
🌬️
Storage Tank Breathing Contamination
Northeast China's extreme temperature differences cause storage tanks to frequently "breathe" in dust, generating sludge at the tank bottom.
🔁
Multiple Transfer Stages
Fuel must pass through "central depot → sub-farm depot → mobile fueling vehicle → agricultural machinery," with each transfer carrying contamination risk.
💰
High Tank Cleaning Costs
Previously, periodic manual cleaning of large storage tanks was required — time-consuming, risky, and waste-generating.
Stage 2 · Fuel Analysis · NEW
🔬 Fuel Analysis
Fuel sampling from the central fuel depot's storage tank and bulk intake revealed contamination from transport pipeline residue and tank-breathing condensation:
| Metric | Before Treatment | After Treatment | Improvement |
|---|
| ISO 4406 Cleanliness | ~22/20/17 | 15/13/10 | 3–4 levels ↑ |
| Free Water (ppm) | ~180 | ≤50 | 72% ↓ |
| Visual Appearance | Cloudy with rust and sediment | Clear, bright | — |
| TAN (mgKOH/g) | 0.15 | 0.07 | 53% ↓ |
| Particle Composition | Pipeline rust, tank-bottom sludge, condensation debris | ≥98% removed at ≥5 μm | 98% ↓ |
Values are representative based on Northeast China farm depot conditions (extreme temperature cycling, bulk intake from external tankers, long-term storage with breathing contamination). Post-treatment ISO 15/13/10 is the verified good level maintained in-depot through periodic high-flow circulation.
Stage 3 · Solution
🛠️ Solution & System Configuration
The farm implemented a "tiered purification strategy" combining a 10m³/h skid-mounted system at the central depot with JY-219A mobile units at sub-farm fueling vehicles. The skid system performs high-flow intake and circulation purification ("unpurified oil does not enter the tank"), while JY-219A units serve as the final checkpoint before fuel enters combine harvesters.
Model
10m³/h Skid + JY-219A (Combined)
Flow Rate
10 m³/h (skid) / 20–40 L/min (JY-219A)
Membrane

Operating Pressure
0.2–0.4 MPa
Regeneration
Gas-pulse regeneration (brief 5-15 min safety pause)
Explosion-Proof
Ex d IIB T4 (depot skid unit)
Strategy
Tiered — depot gatekeeper + mobile terminal
Key design decisions: The skid gatekeeper begins high-flow purification immediately during unloading, ensuring unpurified oil never enters the tank. Periodic 10m³/h circulation of static stored fuel keeps depot diesel consistently within ISO 15/13/10. JY-219A mobile units on sub-farm fueling vehicles provide the final checkpoint before fuel enters combine harvesters, closing the multi-transfer contamination gap from "central depot to field-side."

| Large-Scale Downtime (Fuel-Related) | Periodic incidents | 0 since operation | 100% eliminated |
| Comprehensive Maintenance Cost | High | Significantly reduced | — |
This "combined approach" solution effectively improved the farm's energy security landscape. The 10m³/h skid system effectively reduced the maintenance pressure on the central fuel depot, noticeably extending the storage tank cleaning cycle. Through high-flow purification, in-depot fuel consistently remains within the good level of ISO 15/13/10, effectively reducing the burden on downstream JY-219A and agricultural machinery built-in filter cartridges. Since the complete system went into operation, the farm has not experienced any large-scale downtime incidents caused by fuel quality, with comprehensive maintenance costs significantly reduced.

💡 Lessons Learned
✅
Key Success Factor
The tiered "skid gatekeeper + mobile terminal" combined strategy. The 10m³/h skid system handles high-flow intake and circulation purification at the central depot (eliminating source and secondary contamination), while JY-219A mobile units provide final assurance at sub-farm fueling vehicles. This full-process coverage from "central depot to field-side" closes every contamination transfer gap.
⚠️
Common Pitfall
Many large farms focus only on the central depot and ignore the multiple transfer stages (central depot → sub-farm depot → mobile fueling vehicle → machinery). Each transfer reintroduces contamination, so depot-only purification is insufficient. The tiered approach ensures purification persists through every transfer point down to the combine harvester fuel tank.
🔄
Replication Advice
Directly applicable to large modernized farms with central fuel depots and multiple sub-farm work zones. The 10m³/h skid suits typical large depot throughput; pair with mobile terminal units scaled to the number of sub-farm fueling vehicles. Also ideal for grain cooperatives and agricultural groups with seasonal high diesel turnover and large storage-tank breathing contamination in high temperature-difference regions.

Customer feedback
We used to fear receiving substandard fuel—a single bad batch could damage an entire fleet of harvesters. Now, with these 10m³/h skid units guarding the fuel depot, plus mobile equipment in the fields, we have confidence in our fuel quality. This is not just about saving costs; it is about securing our autumn harvest.
