Technological Advancements
The evolution of nitrogen generation technology has seen significant advancements that have further enhanced its efficiency and utility.
Membrane Technology
Filters Oxygen from Compressed Air via Hollow, Polymeric Fibres
Membrane technology operates by passing compressed air through hollow polymeric fibres. These fibres filter out oxygen and other trace gases, allowing only pure nitrogen to pass through. The result is a continuous supply of nitrogen on-site, eliminating the need for cylinder deliveries and their associated risks and costs.
Adjustable Purity Through Regulating the Volume of Air Passed through the Membrane
One of the key benefits of membrane technology is the ability to adjust the purity of the generated nitrogen. Purity levels range from 95% to 99.5%, covering a broad spectrum of applications. By modulating the volume of ambient air the compressed air system passes through the membrane, users can precisely control the purity level of the output. This gives businesses the flexibility to tailor nitrogen production to their specific needs, whether they require low purity for general applications or high purity for sensitive processes.
Ideal for Applications like Snack Food Packaging, Laser Cutting, and Tank Padding
The versatility of membrane technology makes it ideal for a wide range of applications. In snack food packaging, the adjustable purity levels allow for the precise control required to preserve product freshness. In industries such as laser cutting, a reliable supply of high-purity nitrogen is essential for achieving precision cuts. Similarly, in tank padding, nitrogen creates an inert atmosphere that prevents the risk of explosion or contamination.
PSA (Pressure Swing Adsorption) Technology
PSA Technology is a cornerstone in the field of on-site nitrogen generation. But what is this technology, and what are its associated benefits?
Two-Tower CMS Structure
PSA technology operates on a dual-tower mechanism, each packed with a Carbon Molecular Sieve (CMS). As air passes through one tower, the CMS selectively traps oxygen and other impurities, allowing only nitrogen to pass through, resulting in a consistent supply of highly pure nitrogen.
The Purification Process
The CMS has the unique property of preferentially adsorbing oxygen, water vapours, and other trace gases. This differential adsorption process leads to the separation of nitrogen from the incoming air, leaving behind pure, dry nitrogen gas.
High-Purity Applications
PSA technology’s ability to deliver high-purity nitrogen makes it particularly well-suited for industries where purity is a critical requirement. Purity levels can reach 99.999%, ideal for electronics manufacturing or pharmaceuticals These include chemical processing, where nitrogen is ideal for blanketing and purging processes, and oil and gas production, where nitrogen can be used for pipeline testing, to prevent combustion and oxidation, and to maintain equipment at optimal performance levels.
