How Nitrogen Generators Are Revolutionizing Manufacturing

Key Benefits and Industry Applications -

Nitrogen is an inert gas available in abundance in nature and it makes up most of the air we breathe. Considering its inert nature, it is suitable for many industrial applications in which slow oxidation or fast oxidation to be prevented. Its also odourless and colourless, which means that it can be used in food and beverages industries.    

Unfortunately, nitrogen cannot be used as it is. Before using it, nitrogen has to be processed and separated in usable format. This can be done quickly and efficiently by using device called Nitrogen Generators.

Nitrogen Generators –

A nitrogen generator is a system or device designed to produce nitrogen gas (N?) from the air, which is primarily composed of nitrogen (~78%), oxygen (~21%), and trace gases.nstead of purchasing bottled nitrogen or relying on liquid nitrogen deliveries, companies can produce their own nitrogen on-site, which can be more cost-effective and provide a continuous supply.

Types of Nitrogen Generators :

1. PSA (Pressure Swing Adsorption) Nitrogen Generators

• Working Principle: PSA technology uses a process of adsorbing and desorbing gases under pressure. It typically involves two vessels filled with adsorbent material (such as zeolite), which selectively adsorbs oxygen and other gases, allowing nitrogen to pass through.
• Process: The system operates by alternating the pressure in the vessels to separate the nitrogen from oxygen. When the pressure is high, the adsorbent material captures the oxygen, and when the pressure is lowered, the oxygen is released. This process is continuous.
• Advantages:
  • High purity nitrogen (up to 99.999%).
  • Relatively simple and cost-effective for medium to large-scale applications.
  • Fast production of nitrogen on-demand

2. Membrane Nitrogen Generators

• Working Principle: Membrane technology uses semi-permeable membranes to separate nitrogen from oxygen in compressed air. The membrane allows smaller molecules like oxygen to permeate through it more quickly, while nitrogen (being a larger molecule) passes through at a slower rate, resulting in a nitrogen-rich output.
• Process: Compressed air is forced through the membrane, and the resulting mixture of gases is split, with nitrogen being collected for use.
• Advantages:
  • More compact and simple design than PSA systems.
  • No moving parts, leading to less maintenance.
  • Suitable for smaller-scale applications where high purity is not as critical (typically nitrogen purity up to 95–98%).

Why Nitrogen Generators are becoming ideal choice for manufacturing industries :

·Cost Savings: Over time, producing nitrogen on-site is more economical than purchasing bottled or bulk nitrogen.

·On-Demand Supply: Provides a continuous, reliable supply of nitrogen, reducing the need for stock management of cylinders.

·Purity Control: Most generators allow users to adjust the nitrogen purity to meet specific requirements.

·Space Efficiency: Modern nitrogen generators are compact and can be installed in facilities where space is limited.

·Environmental Impact: By reducing reliance on bottled gas deliveries, nitrogen generators reduce transportation-related carbon emissions and waste from gas cylinders.

Airox Nitrogen Generators :

Airox technologies is one of the leading player in the field of Nitrogen Generators for industrial users. Airox Nitrogen Generators eliminate the expense, inconvenience, hazardous handling, and storage problems often associated with purchased liquid or high pressure cylinder nitrogen.Fully automatic, the generators require no specialized operating personnel. Simply connect an air compressor or central air supply to the generator and your application or nitrogen distribution system to the generator’s nitrogen receiver.
