4 Sets of 20m³/h High-Flow Diesel Filtration Purification Systems

The customer is an enterprise focused on environmental technology, dedicated to the research, development, and application of process technologies that convert raw materials into high-quality diesel.

The customer aims to improve finished diesel cleanliness, reduce overall system maintenance frequency, and enhance market competitiveness.

Prior to this, the customer faced issues including:

High consumable expenditure: Frequent cartridge replacement of downstream precision filter units resulted in high consumable costs.

Fuel contamination issues: Diesel contained process residual oxidized resins and gums, causing finished oil to appear cloudy with sludge accumulation at the tank bottom.

Key indicators exceeding standards: Initial particle counts reached ISO 23/21/18, exceeding precision fuel system requirements.

High maintenance costs: Unplanned downtime for cleaning reactors and piping resulted in high per-unit maintenance costs.

4 sets of industrial-grade high-flow depth filtration systems were installed at key process nodes of the production line (such as reactor outlet and pre-filling).

Filtration precision: 3μm absolute precision

System flow rate: 20m³/h (per set)

Polymer Rigid Composite Membrane: Using Jingyuan® polymer rigid composite membrane, leveraging the oleophilic-hydrophobic properties of the membrane material, it efficiently intercepts fine particles and oxidized polymers (gums) while synergistically removing trace free water, ensuring finished oil is clear, transparent, and meets cleanliness standards.

By introducing the filtration system, the factory's overall maintenance costs were significantly reduced. Thanks to the system's automated operation, unplanned downtime was effectively shortened, and the color and stability of finished diesel were significantly improved, meeting international trade requirements for high-quality fuel.
