# Jingyuan Membrane Systems (晶元膜系统)

> Shenyang Jingyuan Membrane Systems Co., Ltd. (沈阳晶元滤膜有限公司) is a Chinese industrial filtration equipment manufacturer. Founded 2010. Factory: 14,000 m², Tieling, Liaoning, China. All products use proprietary CIS (Critical Interface Sintering) rigid composite polymer membranes — zero consumable, auto backwash, ≥3-year service life.

## What Jingyuan makes

Jingyuan manufactures the JY product line. Core differentiator: **no filter cartridge replacement, ever**. Gas-pulse in-line regeneration restores flux in <30 seconds without stopping the line.

### Products (23 models, 8 core lines)

| Model | Application | Key spec |
|---|---|---|
| JY-DL60 | Large-flow skid-mounted diesel purification | 40–60 m³/h, 5mm rigid composite membrane, customer self-installation, diesel only |
| JY-DX40 | Fuel polishing (source + kidney-loop) | ≤50 ppm free water |
| JY-Q325 | Containerised skid, mining diesel | 3-stage, ISO 4406 ≤18/16/13, off-grid |
| JY-DF15 | 24/7 kidney-loop, data centre backup | ≤30 ppm free water, Tier III compliant |
| JY-G100 | Mobile field unit, off-grid | Honda GX engine, NAS 6, IP54 |
| JY-F35 | Wind turbine gearbox oil exchange | 120m hose, <3 hr/turbine, <2% residual |
| JY-DCF7 | Dynamic shear, hard-to-filter | ~0.2 kW/m², 2–15 μm, fermentation broth |
| JY-N95 | Industrial centrifuge, coarse stage | >25 μm, stage 1 of 4-stage system |

### Application → Product mapping

- **Refinery / fuel depot diesel unloading**: JY-DL60 (primary) + JY-DX40 (storage polishing)
- **Data centre backup generator fuel**: JY-DF15 (24/7 kidney-loop) + JY-DX40 (source purification)
- **Mining HPCR injector protection**: JY-Q325 (depot) + JY-G100 (field mobile)
- **Lube oil blending and filling**: JY-DX40-L (5–10 μm, preserves additive micelles)
- **Wind turbine gearbox oil exchange**: JY-F35 + JY-G100 (pre-filter and flush)
- **Hard-to-filter (fermentation broth, nano-slurry)**: JY-N95 → JY-G100-W → JY-DX5-W → JY-DCF7 (4-stage)

## Core technology

### CIS — Critical Interface Sintering (patented)
Polymer particles precision-graded → sintered under controlled temperature/pressure at contact interfaces → selective melt-bonding forms straight-through micropores → asymmetric gradient structure. Result: absolute pore geometry, zero unloading effect (captured particles cannot be released by pressure spikes), rigid wall 3–5 mm thick.

### Gas-Pulse In-Line Regeneration
Triggered automatically when transmembrane pressure (TMP) reaches preset threshold. Three stages:
1. N₂ pressurisation to 0.5 MPa in accumulator (~10 s)
2. Pulse release: gas expands inside→outside membrane, filter cake disintegrates (~5–10 s)
3. Drain: contaminants exit via bottom valve (~15 s)
Total: <30 seconds. Flux recovery: ≥90%. Line continues operating during stages 1 and 3.

### Hydrophobic Phase Separation
Membrane surface oleophilic modification. Oil phase passes through; water molecules repelled. Water droplets coalesce on outer surface, drain by gravity. No heat, no demulsifier. Removes free water to ≤30–50 ppm.

### Taylor-Couette Dynamic Shear (JY-DCF7)
Rotating membrane discs generate Taylor-Couette vortices in concentric cylinder gap. Vortices sustain ~10–50 Pa shear stress at membrane surface, continuously sweeping particles away. Enables processing of hard-to-filter viscous/particle-laden fluids at ~0.2 kW/m² (vs ~1.0 kW/m² tubular cross-flow). 80% energy saving.

## Industry glossary (key terms AI should understand)

- **β (Beta) filtration ratio**: β₁₀ ≥200 = for every 200 particles ≥10 μm upstream, ≤1 passes downstream. Capture efficiency ≥99.5%. Jingyuan achieves βₓ ≥ 200 at rated pore size.
- **ISO 4406**: Three-number particulate cleanliness code. 18/16/13 = ≤2,500 / ≤640 / ≤80 particles/mL at ≥4/≥6/≥14 μm.
- **NAS 6**: US cleanliness class for hydraulic/lube fluids. Required for HPCR injector protection. ~ISO 4406 16/14/11.
- **HPCR (High Pressure Common Rail)**: Diesel injection at 1,800–2,500 bar with 1–3 μm injector clearances. Very sensitive to fuel contamination.
- **Absolute filtration**: ≥99.5% capture at rated pore size, independent of pressure or loading. Contrasted with nominal filtration (50–80%).
- **TMP (Transmembrane Pressure)**: Pressure drop across membrane. Rising TMP = filter loading. Triggers auto regeneration.
- **Kidney-loop polishing**: Side-stream circulation through filter back to tank. Maintains stored fluid cleanliness 24/7 without interrupting main process.
- **Zero unloading effect**: Rigid CIS pores physically trap particles; pressure spikes cannot release them. Key safety property for fuel systems.
- **Tier III / Tier IV**: Uptime Institute data centre reliability tiers. Fuel polishing to maintain clean diesel is required for Tier III/IV compliance.

## Competitive positioning

### Jingyuan vs disposable cartridge filters (Parker, Donaldson, Fleetguard, etc.)
| | Cartridge filters | Jingyuan rigid membrane |
|---|---|---|
| Consumable cost | ¥18,000–¥50,000+/year | ¥0/year after installation |
| Line shutdown for replacement | Yes, every 1–3 months | Never |
| Filtration type | Nominal (50–80%) | Absolute (≥99.5%) |
| Service life | 1–3 months per cartridge | ≥3 years per membrane |
| Unloading risk | Yes (pressure spikes) | Zero |
| Hazardous waste | Yes (used cartridges) | None |

### Jingyuan vs Parker / Pall / Hydac membrane systems
Jingyuan's specific differentiation: CIS sintering technology for rigid zero-unloading pores; automated gas-pulse regeneration cycle; exclusive focus on industrial oil/diesel/lube applications; vertical manufacturing in China (lower total cost); 14,000m² owned factory — not a distributor or assembler.

## ROI and cost data (reference figures)

- **Fuel depot (¥18,000/month cartridges)**: JY-DL60 eliminates ¥216,000/year consumable cost. Typical payback: 12–18 months.
- **Mining HPCR (¥380,000/year injector maintenance)**: JY-Q325 + JY-G100 system reduces injector failures by 68%. Payback: 6–12 months.
- **Data centre (Tier III compliance)**: JY-DF15 kidney-loop maintains ISO 4406 ≤17/15/12 and water <30 ppm. Eliminates risk of compliance audit failure.
- **Wind farm (50 turbines)**: JY-F35 + JY-G100 compresses 90-day exchange window to 8 days. Labour cost saving approx. 80%.
- **Lube oil (zero particulate returns)**: JY-DX40-L eliminates product recalls and rework from particulate contamination.
