Port Logistics Fuel Quality Control
A Liaoning Port Oil Depot is a large-scale grain and oil transit logistics base in the region, and also a core import and export port in Northeast China. Its associated oil depot undertakes a relatively large finished fuel transfer task, distributing diesel to inland areas or loading it onto ships for export through sea-land intermodal transport, with high requirements for logistics efficiency and fuel quality.
The seaside port oil depot faces unique environmental challenges:
Storage tank bottom sediment: The large day-night temperature difference and high air humidity at the seaside cause large-scale storage tanks to generate sediment and trace free water at the bottom during long-term operation, affecting dispatched fuel appearance.
High salt spray corrosion: Standard carbon steel filtration equipment is highly prone to rusting in seaport conditions, causing equipment housing corrosion and spalling, and even secondary contamination.
High-intensity throughput pressure: As a logistics hub, the depot has a large shipping volume, requiring filtration equipment to operate continuously at 60m³/h high flow rate, without interruptions from frequent cartridge blockage.
Strict downstream customer requirements: Downstream logistics fleets and ship users are relatively sensitive to fuel appearance. Cloudiness or sediment will trigger rejection or complaints.
Jingyuan provided the port with a "seaport dedicated version" 60m³/h purification solution:
Anti-corrosion architecture design: The equipment housing uses a special zinc-rich epoxy primer and polyurethane topcoat multi-layer protection process, with key piping and valves upgraded to 316L stainless steel to resist salt spray erosion.
Polymer Rigid Composite Membrane: Using Jingyuan® polymer rigid composite membrane, leveraging the oleophilic-hydrophobic properties of the membrane material, it efficiently intercepts particulate impurities while synergistically removing trace free water, ensuring dispatched fuel is clear, transparent, and meets cleanliness standards.
High-flow low-pressure-drop design: Optimized flow channel design ensures relatively low system internal pressure drop during 60m³/h full-load operation, without affecting pump delivery efficiency.
Robust and reliable performance: Structural components are reinforced to withstand vibration and harsh operating conditions in the port operation zone.
The system's deployment effectively resolved the fuel appearance issues that had troubled the port oil depot. Even in high-humidity weather, diesel treated through the 60m³/h system maintained its clear and transparent appearance. The equipment's anti-corrosion performance has withstood the test of sea winds, with the exterior remaining intact to date. This not only ensures efficient port logistics operations but also establishes a good reputation for the customer's fuel transit quality.
Operating an oil depot by the sea means a protracted battle against moisture and salt. Jingyuan's customized 60m³/h units are robust and durable, withstanding the harsh port environment, effectively ensuring the cleanliness of dispatched diesel. It is our reliable gatekeeper for port logistics.
