Membrane Separation Nitrogen Generator

Membrane separation nitrogen generator is an efficient and energy-saving nitrogen preparation equipment. It uses the principle of selective permeation of hollow fiber membranes to separate impurities such as oxygen and water vapor in compressed air to obtain high-purity nitrogen. This technology is widely used in chemical, electronics, food packaging, medicine, oil and natural gas industries, and provides a stable and reliable nitrogen supply.

Compared with traditional PSA (pressure-switching adsorption) nitrogen production technology, the membrane separation nitrogen generator has the advantages of simple structure, no moving parts, low maintenance costs, and low energy consumption. It is especially suitable for nitrogen demand scenarios with small and medium flow and medium purity (95%~99.9%).

Core technology principle

The core component of the Membrane separation nitrogen generator is the hollow fiber membrane group, which works based on the difference in permeability rate of gases in the membrane material. When compressed air enters the membrane group, "fast gas" such as oxygen and water vapor are preferred to be discharged through the membrane wall, while nitrogen remains in the membrane as "slow gas", thereby achieving nitrogen-oxygen separation.

Key Benefits:

• No consumables: no need to change adsorbent frequently, reducing operating costs
• Silent operation: no valve switching noise, suitable for precision working environment
• Start and use: The machine can produce qualified nitrogen without preheating
• Modular design: The number of membrane groups can be flexibly expanded according to requirements

Technical Specifications & Performance Parameters

Flow Rate vs. Purity Curve
(Graph Note: Nitrogen purity shows a gradual decline as flow rate increases. Typical flow rate at 99% purity is 100 Nm³/h.)

Industry application cases

1. Electronics industry: used for protection of inert gases such as SMT patches and semiconductor packaging, with a purity of ≥99.5%, oil-free and dust-free, ensuring a precise manufacturing environment.

2. Food packaging: Nitrogen-filled to keep fresh (99% purity), inhibit microbial growth, extend food shelf life, and meet FDA certification requirements.

3. Oil and natural gas: pipeline purge, storage tank coverage, explosion-proof and safe, adapting to -30°C field environment.
