80 m³/h Ultra-High Flow Diesel Filtration:
Zero Outbound Quality Risk at a Regional Fuel Hub

Two customised JY skid systems — Henan Province petrochemical storage and distribution terminal, China

Project Overview

1. The Challenge: Speed and Quality Under Simultaneous Pressure

As a high-throughput regional fuel distribution hub serving thousands of logistics fleets and industrial operators, the terminal faced a fundamental conflict: the faster the throughput, the harder it is to maintain outbound fuel quality.

Flow rate bottleneck at the loading rack

Conventional filtration equipment typically caps out at 30–40 m³/h due to high differential pressure at elevated flow rates. With daily dispatch volumes in the thousands of tonnes, this throughput ceiling created chronic tanker queuing at the loading bays, increasing logistics costs and eroding customer relationships.

Tank bottom contamination mobilised at high flow

Large storage tanks accumulate sediment, mill scale, and condensed water at the bottom over years of operation. At 80 m³/h suction intensity, these contaminants are readily entrained into the loading pipeline — creating a direct quality risk on every dispatch cycle.

National VI compliance requirements

As Henan Province and surrounding regions enforced China’s National VI emission standards across the fuel supply chain, downstream customers’ expectations for particulate count and water content reached near-laboratory levels. Any measurable deviation threatened both product liability and brand reputation.

Maintenance downtime risk during peak operations

Frequent filter cartridge replacement or unplanned maintenance during high-load periods would directly paralyse the loading line — an unacceptable operational risk for a hub handling critical regional fuel supply.

2. The Solution: Customised 80 m³/h Jingyuan Skid Systems

Jingyuan’s engineering team developed a purpose-built configuration to simultaneously address throughput capacity, contamination control, and operational continuity.

Ultra-high flow skid design

The system uses an optimised internal flow channel geometry that expands the effective filtration area, maintaining extremely low initial differential pressure even at 80 m³/h. This achieves double the throughput of conventional equipment without sacrificing filtration precision.

Redundant parallel membrane array

Multiple JINGYUAN® rigid composite polymer membrane assemblies are arranged in parallel within each skid. This configuration provides exceptionally high dirt-holding capacity — critical for capturing the heavy contamination loads from aged tank bottoms — while substantially reducing maintenance frequency compared to single-element designs.

High-flow water separation

The membrane array incorporates Jingyuan’s hydrophobic phase separation technology, optimised for effective water removal at 80 m³/h flow rates where conventional coalescing elements lose efficiency. The oleophilic-hydrophobic membrane surface separates free water without heat or chemical demulsifier.

Petrochemical-grade safety compliance

The complete system is engineered to the highest petrochemical explosion-proof and static discharge standards. At 80 m³/h, fuel velocity generates significant static charge; the system’s anti-static earthing architecture ensures safe dissipation throughout all operating conditions.

5. Technical Notes for Engineers

Why conventional filters fail at 80 m³/h

At flow rates above 40 m³/h, three failure modes become critical in traditional coalescing filters: (1) shear forces re-emulsify coalesced water droplets before they can settle, reducing water separation efficiency to below 70%; (2) differential pressure rises steeply across glass-fibre depth media, forcing premature cartridge replacement; (3) glass-fibre media deformation under sustained high pressure creates bypass channels, destroying filtration precision.

How Jingyuan rigid membrane maintains precision at 80 m³/h

The JINGYUAN® CIS (Critical Interface Sintering) rigid composite polymer membrane uses an asymmetric gradient pore structure with 3–5 mm wall thickness. Unlike glass-fibre media, the rigid pore geometry does not deform under elevated differential pressure. Water separation relies on the membrane’s oleophilic-hydrophobic surface chemistry — a physical mechanism independent of flow velocity — rather than on droplet coalescence and gravity settling.

Static discharge at high flow rates

At 80 m³/h, fuel velocity through pipework and filter elements generates electrostatic charge exceeding the ignition threshold for hydrocarbon vapours. The Jingyuan system includes fully bonded anti-static earthing architecture on all conductive components, with resistance verified to <10⁶ Ω per petrochemical standard requirements.
