Ⅰ. Main types of industrial gases and filtration challenges

Industrial gas systems can be divided into three categories, each of which has unique requirements for filtration technology:

  • Compressed air systems: need to deal with lubricating oil mist (0.1-5μm), water vapor and pipeline particles, among which Class A gas (food and medical grade) requires residual oil content <0.01mg/m³;
  • Special process gases: such as inert gases such as helium and argon, metal ions need to be controlled to ppt level, especially electronic special gases for semiconductors require particles <0.003μm;
  • Industrial waste gas: contains complex components, such as VOCs, acidic gases (SOx/NOx) and heavy metal dust, and must meet emission regulations such as NESHAP. A study by Festo in Germany shows that untreated compressed air can increase the failure rate of pneumatic components by 300%.

Ⅱ. Filtration technology focus and innovative solutions

Modern industrial gas filtration focuses on three core issues:

  • Particle retention: relying on gradient filter materials (such as sintered stainless steel + PTFE coating) to increase the efficiency of 0.1μm particles to 99.995%; Liquid pollutant separation: using cyclone + coalescence combination technology, such as Atlas Copco’s Oil-X series to achieve a residual oil content of 0.003ppm;
  • Chemical pollutant adsorption: relying on activated carbon/molecular sieve media, Kobelco’s Kobelco filter can remove oil mist and acidic gas at the same time.
  • It is worth noting that the new EU regulation EU 2023/1789 has included nano-scale particles in the mandatory monitoring scope, pushing the filtration accuracy into the sub-micron era.

Ⅲ. Filter classification and technological evolution

Industrial gas filtration technology has formed a complete system architecture according to different application scenarios and filtration accuracy:

  1. Pretreatment filter: At the basic filtration level, the primary pre-filter bears the heavy responsibility of the first line of defense, mainly intercepting large particle pollutants above 5 microns. This type of filter generally uses metal sintered mesh or synthetic fiber as filter material, and plays a key role at the air compressor inlet and the front end of the pipeline.
  2. Precision filter: The core link of industrial gas purification, its filtration accuracy usually reaches 0.1 micron level. This level of filter needs to take into account both high-efficiency interception and low pressure drop, and the technical difficulty is relatively high. The current mainstream solution uses gradient density glass fiber composite materials with special surface treatment processes.
  3. Ultrapurification filtration: Semiconductor manufacturing, pharmaceutical production and other scenarios require a filtration accuracy of 0.003 microns, and there are also strict restrictions on the precipitation of metal ions. This level of filter often uses a composite structure of ceramic membrane and molecular sieve, combined with a special sealing process.

From the perspective of technological evolution trends, the field of industrial gas filtration is undergoing innovation in three dimensions. In terms of materials, the application of new nanomaterials and bio-based materials continues to break through performance limits; in terms of structural design, modularization and integration have become the mainstream direction; intelligent transformation enables traditional filtration equipment to have the ability to predict maintenance and optimize energy efficiency.
