The Role of Nitrogen Booster in Nitrogen Generator

The role of nitrogen booster in nitrogen generator

In the 1970s, Carbotech Company (formerly BF Company) was the first in the world to develop nitrogen production processes and carbon molecular sieves for nitrogen production, which led to rapid development of nitrogen production equipment in the 1980s and 1990s. With the development of science and technology, the application scope of nitrogen is increasingly expanding, from traditional industries such as metallurgy and chemical engineering to industries such as textiles, electronics, pharmaceuticals, food, and rubber. The method of production has evolved from the previous single cryogenic method to the development of nitrogen production equipment based on the principle of pressure swing adsorption.

Pressure swing adsorption (PSA) is an advanced gas separation technology that plays an irreplaceable role in ambient temperature gas production. PSA pressure swing adsorption nitrogen production device is a high-tech and energy-saving separation technology that directly produces nitrogen from air at room temperature. It uses compressed air to undergo a series of purification processes such as oil removal, water removal, and dust removal, followed by pressure swing adsorption to separate and produce nitrogen. Due to dynamic effects, the diffusion rate of oxygen on carbon molecular sieves is significantly higher than that of nitrogen. When adsorption reaches equilibrium, nitrogen is enriched in the gas phase. Imported PLC automatic control technology is used to achieve continuous production of high-quality nitrogen gas. It has the advantages of compact equipment, small footprint, fully automatic operation, reliable operation, fast start stop, low operating cost, convenient production and maintenance at room temperature, and the purity of nitrogen can be adjusted appropriately with flow rate. Non polluting environment, it is an efficient on-site gas production device.

Carbon molecular sieve is the core part of PSA nitrogen production, with a large number of micropores distributed on its surface. Under a certain pressure, it adsorbs a large amount of oxygen, carbon dioxide, moisture, etc. from the air, while nitrogen adsorption is very small, becoming product gas flowing out from the top of the adsorption tower. When the pressure drops to atmospheric pressure, the hydrogen, carbon dioxide, and moisture adsorbed by it are released from the carbon molecular sieve. The PSA nitrogen generator is generated based on this principle. Generally, two adsorption towers are set up in the system, one tower for nitrogen adsorption and the other tower for desorption and regeneration, alternately circulating to continuously produce nitrogen gas. Usually, customers use nitrogen at two pressures, one below 10 bar and the other above 10 bar. Especially for pressures above 10 bar, customers need to use a nitrogen booster to increase nitrogen to meet actual process requirements.

Nitrogen booster, also known as nitrogen booster pump, belongs to reciprocating booster pump, different from plunger pump, it is classified as piston booster. The working principle of a nitrogen booster is to use the pressure difference formed by the area ratio to output high-pressure nitrogen gas generated by the small piston through the small force of the large piston. The direction of the high-pressure one-way valve controls the output of the nitrogen gas at the high-pressure end. Nitrogen is an inert gas, and more than half of the air contains nitrogen. Therefore, the development of nitrogen boosters provides a convenient tool for increasing the pressure or filling nitrogen cylinders in nitrogen generators. The application range of nitrogen is very wide, such as in automobiles, aviation, laboratories, medical care, factories, etc., which also reflects the high pressure requirements of nitrogen boosters in these fields, especially for nitrogen, which cannot be separated. So its application scope can be extended to the following aspects：

1. Nitrogen filling of accumulator.

2. Nitrogen power source for nitrogen circulation and protection system

3. Laboratory high-pressure nitrogen filling reactor auxiliary simulation experiment.

4. High pressure nitrogen filling for car and airplane tires.

5. Nitrogen in the firefighting industry is used as a high-pressure booster to promote the spraying of chemicals.

6. High pressure gas assisted injection molding is used in the gas assisted injection molding industry of the mold industry.

7. Typical application of physical foaming in Shenxian Shenlan.

8. Airtightness test and substitute helium gas for leak detection.

The characteristics of nitrogen booster are reflected in its wide output pressure range, strong applicability, flexible application, customizable multiple pressures, safe operation, simple maintenance, and long service life.
