In the aviation kerosene industry, fluid filtration products are the key technologies to ensure fuel cleanliness, flight safety and efficient engine operation, and run through the whole process of refining production, storage and transportation management, airport refueling and aircraft fuel supply.

Refining and refining process: When the crude oil is processed into aviation kerosene (such as Jet A/A-1), it is necessary to remove the residual catalyst powder, iron sulfide and other particle impurities through the deep filtration system to prevent the reactor blockage in the subsequent hydrodesulfurization process; The coalescing filter is used to separate the free and emulsified water in the fuel, ensuring that the moisture content is strictly ASTM D1655 (less than 30 ppm).

Storage and transportation: In strategic oil depots or transit tanks, the microbial interceptor filter element can inhibit bacteria and fungi (such as Cladosporium bacteria) that grow in the fuel due to long-term standing, so as to avoid pipeline corrosion and filter blockage caused by biofilm formation; During transportation, high-precision particle filters (accuracy 1-5 microns) installed in tank cars or pipelines can intercept contaminants such as rust and welding slag to ensure the stability of fuel during long-distance transportation.

Airport refueling and aircraft refueling: Jet fuel is preceded by a multistage purification system, including a agglomeration separator (removing water), an adsorption filter (removing trace amounts of dissolved water) and an absolute precision filter (intercepting sub-micron particles) to ensure that the fuel entering the aircraft fuel tank meets SAE ARP1408 specifications. In the aircraft fuel system, the high-pressure filter unit needs to withstand extreme low temperatures (altitude -50 ° C) and fluctuating pressure to continuously filter out metal debris caused by the wear of the fuel pump and protect the engine fuel nozzle from the risk of stuck.

Environmental and intelligent trends: In response to the aviation industry's carbon reduction needs, esterification reaction byproducts in the production of bioaviation coal (SAF) need to achieve efficient solid-liquid separation through nanofiber filtration membranes; In terms of intelligence, online particle counters and humidity sensors can monitor fuel cleanliness in real time, combined with self-cleaning filter technology (such as backwash design) to reduce the frequency of downtime maintenance.

At present, the aviation kerosene industry is addressing the challenges of high-sulfur crude oil processing and the compatibility needs of sustainable aviation fuels through innovative technologies such as the development of high-temperature and antistatic filters (to prevent the accumulation of static electricity in fuel) and the development of super-hydrophobic coating filters (to improve dehydration efficiency), providing a core guarantee for the safety and low-carbon goals of the global aviation industry.
