Compressing Nitrogen vs Air: What's Different?

Compressed nitrogen and air are used in many different industries. Although compression methods and equipment are similar, property differences between these gases can impact equipment design. Get more news about nitrogen compressor exporters,you can vist our website!

Nitrogen is a pure gas, while air is a mixture of multiple gases such as nitrogen, oxygen, argon, and other trace gases. Compressing nitrogen is simpler than compressing air since there are no other gases to consider.

Nitrogen is an inert gas, making it less reactive than oxygen or other gases. When compressing nitrogen, it is essential to ensure the gas remains contaminant-free.

Compressing nitrogen and air share many similarities, but their different properties will affect some portions of the equipment design, safety considerations, and compressor packaging.

Nitrogen Applications
As a versatile and essential gas for everyday production, nitrogen covers various applications across many industries. Some include:

Electronics: Nitrogen is used to manufacture electronic components (semiconductors, LCDs, and computer chips) to create a controlled environment free of oxygen and other impurities. Those gases can significantly damage electronic components’ capabilities. This is a rapidly expanding industry requiring increasing demand for pressurized nitrogen.

Chemical: Nitrogen is also required for many processes, including the production of ammonia and fertilizers. Nitrogen is used to neutralize the potentially harmful effects of oxygen in chemical manufacturing operations through nitrogen blanketing. Nitrogen blanketing introduces nitrogen gas into a storage vessel that will be used to store chemical components or finished chemical products.

Welding: Nitrogen acts as shielding to help improve the welding quality. It protects the weld from surrounding air, which contains moisture and other impurities that can negatively impact weld strength and quality.

Food & Beverage: Nitrogen helps with packaging and preservation. Since nitrogen is an inert gas, it prevents oxidation and spoilage for food products such as potato chips, nuts, fruits, and dairy.

Medical: Nitrogen is used in many intricate surgeries and therapy practices to freeze and destroy abnormal tissue growth. It is also used in medical imaging, like MRIs, to cool the equipment.

For many manufacturing applications, nitrogen is safer as part of the process because it is non-flammable and non-reactive.

However, when compressing nitrogen, there are some additional safety considerations for the compressor to avoid harm to the operator. Since 78% of the air we breathe is nitrogen, nitrogen is assumed to be not hazardous. However, high levels of pure nitrogen can cause you to feel dizzy and lightheaded. Exposure to pure nitrogen without proper ventilation/oxygen present can result in loss of consciousness and even death. To prevent this, nitrogen compressors will typically include the following safety features:
