Function:

Protective atmosphere: In many high-temperature processing procedures, such as annealing and metal film deposition, nitrogen is used as an inert gas to prevent unwanted reactions between oxygen or other reactive gases and the material. Nitrogen can create a stable oxygen-free environment, preventing oxidation and other chemical reactions from occurring.

Clean gas: Nitrogen, as a clean gas, is widely used to remove residual substances, gases and moisture from production equipment, ensuring the normal operation of the equipment and improving production efficiency.

Cost reduction: In the production process, the use of nitrogen can reduce exhaust emissions, save energy, and lower the risk of equipment failure.

Nitrogen is an inert gas, meaning that under normal conditions it does not react with other substances. This feature makes it very ideal for 3D printing applications. When 3D printers use lasers to sinter materials together, intense heat can cause the materials to react with oxygen in the air, leading to oxidation. This oxidation will reduce the quality of the final product, cause defects and weaken the material. By filling the printing chamber with nitrogen, the oxygen content can be significantly reduced, preventing oxidation and ensuring higher-quality printing.

The use of nitrogen in 3D printing offers multiple advantages:

It enhances print quality by preventing oxidation, thereby generating stronger and more durable components. This is particularly important when printing with metals, as oxidation can significantly affect the mechanical properties of the final product.

Nitrogen can improve the surface finish of 3D printed parts. In the absence of oxygen, the material melts more evenly, resulting in a smoother and finer surface. This can reduce the demand for subsequent processing, saving time and resources.

The use of nitrogen can expand the range of materials that can be printed. Some materials are highly reactive and cannot be printed in an oxygen-rich environment. By using nitrogen, these materials become feasible, offering new possibilities for 3D printed products.

With the continuous development of 3D printing, the use of nitrogen may become more widespread. As companies seek to produce more complex and high-quality components, the demand for controlled environments will increase. Furthermore, as more highly reactive materials are used in 3D printing, nitrogen will play a key role in making these materials available. Using a PSA nitrogen generator to produce nitrogen on-site not only improves the printing quality but also expands the range of printing materials.

In the petrochemical industry, the role of nitrogen is mainly reflected in the following aspects:

• Enhance oil recovery rate: Nitrogen can be used to increase the pressure within oil Wells, thereby boosting oil production, especially in enhanced oil recovery (EOR) projects.

• Preventing combustion and corrosion: Nitrogen, as an inert gas, can prevent the combustion of flammable gases and protect the oil pipe from downhole corrosion.

• Chemical equipment protection: In chemical production, nitrogen can be used to prevent oxidation and corrosion of equipment, ensuring production safety.

These functions make nitrogen an important public utility medium in the petrochemical industry.

AGHA nitrogen gas source in the laboratory, the nitrogen generator is safe and convenient to use, greatly improving the efficiency of the laboratory. The nitrogen generator makes the gas supply for gas chromatographs safer and more efficient. The main reason why users choose nitrogen generators is that they can continuously supply gas without interruption and can start or end at any time. The gas in the gas cylinder will eventually run out and needs to be refilled and replaced at irregular intervals. Not only is it time-consuming and laborious, but sometimes it also delays the experimental work. Secondly, there is the issue of safety. The transportation, installation and use of gas cylinders all require many steps and precautions. A single misstep may lead to serious safety accidents. In short, nitrogen generators are both economical and safe, making them the ideal choice for gas chromatography laboratories!

Nitrogen is the most widely used auxiliary gas in laser cutting, which is attributed to its reactive inertness. It is used to ensure that the laser performs at high quality, especially when high-quality cutting is required. Nitrogen can eliminate oxygen in the air, thereby preventing oxygen from reacting with hot metals and achieving ideal, bright cuts without affecting the color of the material (depending on the purity of the nitrogen used). Nitrogen is an inert gas. It enables the laser to operate in an oxygen-free environment and prevents the oxidation of the cut edges. Nitrogen also plays a significant role in reducing costs, accelerating cutting speeds, enhancing productivity, improving control performance and achieving efficient processing. Optional "plug-and-play" solutions are available for on-demand nitrogen supply.

The application of nitrogen (N₂)

Inert protection: Nitrogen is often used in the production process to provide an oxygen-free environment for pharmaceutical raw materials and prevent oxidation reactions from occurring.

Purging and cleaning: Nitrogen is used for purging reactors and equipment to ensure that there are no contaminants inside the system.

Packaging gas: When packaging drugs, nitrogen is used to replace the air inside the package, extending the shelf life of the drugs. 

The main uses of nitrogen in the food industry include:

• Food storage and packaging: Nitrogen can replace the oxygen inside the packaging, inhibit the growth of microorganisms and extend the shelf life of food.

• Fruit and vegetable preservation: Control the nitrogen content in the controlled atmosphere chamber to slow down the oxidation and quality loss of fruits and vegetables.

• Rapid freezing: Utilizing the low temperature of liquid nitrogen to rapidly cool food and maintain its quality.

• Cold chain transportation: Nitrogen is filled in the transportation containers to maintain a low-temperature environment and ensure food safety.

• Preventing oxidation: Nitrogen can prevent the oxidation of dairy products, meat and other foods, extending their shelf life.

These uses demonstrate the significance of nitrogen in food processing and preservation.

1. Improve combustion efficiency 

After using industrial oxygen-assisted combustion devices, the oxygen concentration during the combustion process is greatly increased, and the fuel can burn more fully. In this case, the release of energy is more rapid, and efficiency naturally rises accordingly.

2. Reduce emissions

Efficient combustion means less unburned matter and pollutant emissions. As we all know, reducing emissions is the key to environmental protection, and industrial oxygen-assisted combustion devices are precisely effective tools to achieve this goal.

3. Cost savings

The combustion-supporting device can optimize the use of fuel, reduce fuel waste, and thereby lower production costs. This is undoubtedly a considerable savings for many enterprises.

The application scope of industrial oxygen-assisted combustion devices is becoming increasingly wide, covering multiple industries. Let's take a look at its performance in different fields:

1. "Metallurgical Industry

In the metallurgical industry, oxygen-assisted combustion devices are mainly used in blast furnaces and electric arc furnaces, which can significantly increase the output and quality of molten iron. The oxygen provided by large VPSA oxygen generators can make the smelting process more efficient.

2. Chemical Production

In the chemical industry, oxygen-assisted combustion devices can be used in reactions during the combustion process, which can increase the reaction rate and boost product output. Imagine that if the response speed is accelerated and the production cycle is shortened, the competitiveness of the enterprise will undoubtedly be greatly enhanced.

3. Power generation industry

In the power generation industry, oxygen-assisted combustion can enhance combustion efficiency and make the operation of power generation equipment more stable. Especially in some coal-fired power plants, the application of oxygen-assisted combustion devices can significantly reduce carbon dioxide emissions.

4. "Waste incineration

In the process of waste incineration, oxygen-assisted combustion not only enhances the incineration efficiency but also reduces the generation of harmful gases. Facing the increasing problem of garbage disposal, this is undoubtedly a solution.

In fishery farms, oxygen is mainly used to increase the level of dissolved oxygen (DO) in water. Dissolved oxygen is the form of oxygen in water that can be directly utilized by fish and is crucial for their respiratory activities. The appropriate dissolved oxygen level has a direct impact on the growth rate, health condition and survival rate of fish. Studies show that maintaining the dissolved oxygen level above 6 mg/L can significantly increase the growth rate and immunity of fish. For instance, salmon grow 20% faster in an environment with a dissolved oxygen level of 8 mg/L than in a condition of 5 mg/L.

Through long-term practice and exploration, it has been found that the scientific use of oxygen can play an improving role in the three stages of papermaking. This will further reduce environmental pollution and increase (improve) production efficiency. Bleaching and delignin: Using oxygen instead of chlorine or chlorine dioxide can reduce the impact on the environment and enhance safety. Oxygen delignin can remove 40-50% of the residual lignin in unbleached pulp, reduce the demand for irritating chemicals and lower production costs. Recycling (deinking) : Oxygen can improve the flotation process during deinking, enabling better separation of ink from paper fibers and enhancing the quality of recycled paper. Wastewater treatment A large amount of organic wastewater is produced in the papermaking industry. By using oxygen (through oxygen injection or aeration), the dissolved oxygen level in the water can be increased, promoting the growth and reproduction of aerobic microorganisms, decomposing organic matter in the wastewater, reducing BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand), and effectively purifying the wastewater before its discharge, thereby improving water quality. The above improvements can, to a large extent, help papermaking enterprises enhance the quality of their final products and achieve a more efficient, environmentally friendly and economical production process. This also makes oxygen an indispensable production material in the papermaking industry.
