The core of membrane separation is the physical process of gas separation based on the different diffusivity of different components in the air in the membrane fiber wall (polymer material). Polymer material is made into the thickness of the hollow fiber membrane as a human hair silk, the gas inside the hollow fibre membrane by the different components of the gas in the fibre wall seepage velocity is different, lead to different osmotic quantity, through a certain length of fiber membrane selective permeability, at the end of the film fiber get need purity nitrogen (90 ~ 99.99%), membrane fiber wall osmosis oxygen-enriched gas emissions and the concentration of oxygen enrichment can reach about 40%.

Membrane separation technology is now extensively utilized across various industries including oil (for tertiary oil as well as and natural gas recovery); chemical (for purging, chemical displacement, and as protective gas); metallurgy (for carburizing, annealing, and shielding gas used for welding); electronics (for electronic component protection); transportation (for flammable and explosive material protection); coal (for fire suppression and explosion prevention); agriculture (for storage protection of crops against mold, bacteria, and pests); and pharmaceuticals (for nitrogen blanketing and as protective inert gas in medicinal packaging).

• Low Energy Consumption: Ultra-fine hollow fiber membranes provide exceptional separation performance and large specific surface area, achieving high nitrogen recovery rates, consuming 15-25% less energy than other air separation technologies.
• High reliability: Unlike other gas separation equipment, hollow fiber membrane nitrogen systems operate statically without moving parts, requiring minimal maintenance for safe and continuous operation.
• Long lifespan: The membrane separation system boasts a life span of over 6-8 years.
• Proven technology: Thousands of units are successfully operating worldwide, demonstrating effective performance.
• Flexible operation: Increasing nitrogen output is as simple as adding more membrane separators, a flexibility unmatched by other technologies. Additionally, the concentration and flow rate of nitrogen produced can be adjusted as required.
• Compact and lightweight: Due to the compact structure of membrane separation systems, there is no need for significant infrastructure investment, and installation costs are low.
• Low dew point: The membrane separation process also removes oxygen and water vapor, resulting in a low dew point for the nitrogen product.
• High automation: The concentration and output of the product gas, as well as temperature and pressure, can be automatically controlled as required.
• No special environmental requirements: The system operates without open flames, allowing it to function in harsh conditions and explosive atmospheres.
• Customizable design: Systems are designed according to customer specifications to meet diverse requirements.
