N-GEN PSA Nitrogen Generators

The N-GEN nitrogen generators extract the available nitrogen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology. During the PSA process, compressed, cleaned ambient air is led to a molecular sieve bed, which allows the nitrogen to pass through as a product gas but adsorbs other gases. The sieve releases the adsorbed gases into the atmosphere when the outlet valve is closed, and the bed pressure returns to ambient pressure. Subsequently, the bed will be purged with nitrogen before fresh compressed air enters for a new production cycle. In order to guarantee a constant product flow, N-GEN nitrogen generators use two molecular sieve beds, which alternatively switch between the adsorption and the regeneration phase. Industrial nitrogen gas can also be produced by the separation of gaseous air using membrane technology or fractional distillation of liquid air using cryogenic technology. The best production method depends on the purity, volume, and consumption regime required.

Nitrogen Generator FAQs

How does a nitrogen generator work?

Nitrogen generators operate on principles such as pressure swing adsorption (PSA) or membrane separation. In PSA, air is passed through a bed of adsorbent material, which selectively captures oxygen and other trace gases, allowing nitrogen to pass through. Membrane separation uses semi-permeable membranes to separate nitrogen from other gases based on size and permeability.

What are nitrogen generators used for?

Industrial nitrogen generators create pure nitrogen from compressed air. They play a crucial role in food packaging, electronics, pharmaceuticals, chemicals, oil & gas, automotive, and aerospace industries. They preserve freshness, prevent oxidation, maintain product integrity, ensure safety, and enhance performance in various applications.

What are the risks of nitrogen generators?

While nitrogen generators are generally safe when operated correctly, there are potential risks associated with oxygen depletion in enclosed spaces if leaks occur or if the system malfunctions. Following proper installation, operation, and maintenance procedures is crucial to mitigate these risks and ensure safety.

How long does a nitrogen generator last?

The lifespan of a nitrogen generator depends on factors such as the type of technology used, operating conditions, and maintenance practices. Many PSA systems have a life cycle of 20 to 25 years. Membrane nitrogen generators can last up to 15 years before replacement is necessary. Regular maintenance and servicing can help extend the lifespan of the equipment.
