99% Nitrogen Generator Supplier

What technology does the nitrogen generator use to achieve 99% purity?

As a device that can extract and separate high-purity nitrogen from the air, the nitrogen generator can achieve a purity of 99% or even higher. This achievement is inseparable from the key technologies behind it.

Ⅰ. PSA pressure swing adsorption technology
PSA pressure swing adsorption technology is one of the main technologies for nitrogen generators to achieve high-purity nitrogen. This technology is based on the difference in adsorption capacity of different gases in molecular sieves, and achieves the separation of nitrogen and oxygen through pressure changes. Specifically, when compressed air passes through an adsorption tower filled with a specific molecular sieve, oxygen molecules are adsorbed on the molecular sieve due to their greater adsorption capacity, while nitrogen molecules are able to pass through due to their weaker adsorption capacity, thereby obtaining high-purity nitrogen at the outlet of the adsorption tower. By periodically changing the pressure in the adsorption tower, effective separation and purification of oxygen and nitrogen are achieved.

Ⅱ. Hollow fiber membrane separation technology
Another technology to achieve 99% purity nitrogen is hollow fiber membrane separation technology. This technology uses the selective permeability of hollow fiber membranes to separate oxygen and nitrogen in the air. Hollow fiber membranes are composed of a series of tiny tubular membranes with specific pore sizes and surface properties that allow nitrogen molecules to pass through while blocking oxygen molecules. When compressed air passes through the hollow fiber membrane, nitrogen molecules can quickly pass through the membrane pores into the membrane, while oxygen molecules are trapped outside the membrane, thereby achieving effective separation of nitrogen and oxygen.

Ⅲ. Technical characteristics and advantages
Whether it is PSA pressure swing adsorption technology or hollow fiber membrane separation technology, they have the following common characteristics and advantages:

1. High efficiency: Both technologies can achieve efficient gas separation and purification, ensuring that the purity of nitrogen reaches more than 99%.

2. High degree of automation: The nitrogen generator adopts an advanced control system, which can realize automatic operation and reduce the need for manual intervention.

3. Energy saving and environmental protection: Compared with traditional liquid nitrogen or bottled nitrogen, the nitrogen generator does not need to be stored and transported, which reduces costs and reduces environmental pollution.

4. Good stability: The nitrogen generator has stable performance and can operate continuously for a long time to ensure a stable supply of nitrogen.

The nitrogen generator achieves the preparation of high-purity nitrogen by adopting key technologies such as PSA pressure swing adsorption technology and hollow fiber membrane separation technology. The application of these technologies not only improves the purity of nitrogen, but also makes the operation of the nitrogen generator more efficient, energy-saving and environmentally friendly.
