Diesel Purification
The customer is an international engineering contractor, specializing in EPC (Engineering, Procurement, and Construction) and operation of large-scale mining projects in the African region. The mining area it serves is located in a harsh environment with a complex supply chain, placing high demands on equipment reliability.
The customer hopes to ensure that its generator sets and heavy-duty mining trucks at the African mining site can operate stably, especially for modern diesel engines equipped with HPCR systems.
Previously, the customer's main issues included:
Poor fuel quality: Locally supplied diesel has severe particulate contamination (typical ISO codes reaching 24/22/19), causing frequent blockage and wear of precision injector nozzles.
Higher maintenance costs: Due to unclean fuel, the engine's built-in primary and secondary filter cartridges frequently block and require frequent replacement. In remote Africa, spare parts logistics costs are high.
Unplanned downtime: Key generator set failures due to fuel system issues cause power outages across the entire mining area, resulting in significant production losses.
Shortened equipment life: Impurities and trace free water in diesel affect fuel stability, increasing the risk of fuel tank corrosion.
The customer procured multiple sets of Jingyuan 12m³/h diesel filtration equipment, deployed at the mining area's main storage tank and fueling island front end.
Flow rate: 12m³/h high-flow rapid purification
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.
Filtration precision: 3μm absolute precision
Function: Effectively removes particulate contaminants and synergistically removes trace free water before fuel enters mining equipment, ensuring fuel cleanliness.
By deploying this batch of filtration systems, the mining area's diesel quality was significantly improved. Maintenance data shows a noticeable decrease in the unplanned replacement rate of engine injector nozzles. Additionally, the fuel cartridge replacement cycle for generator sets has been effectively extended, reducing consumables procurement and logistics costs. Stable power supply ensured continuous mining, and productivity was improved.
In the harsh environment of African mining, fuel quality is an important variable affecting availability rates. Jingyuan's filtration equipment effectively improved diesel quality. Our generator sets' reliability has been significantly improved, and we have saved considerable spare parts logistics costs.
