Reduce Costs with On-Site Nitrogen Generation
Generating nitrogen on-site significantly cuts nitrogen consumption costs, which is why most businesses invest in GN2 systems. Purchasing nitrogen in gaseous or liquid form can range from $0.60 to $2.88 per 100 cubic feet, depending on factors like consumption volume, product type, location, and vendor. However, these prices only cover the gas or liquid itself and don't include additional costs such as:
- Delivery Fees
- Monthly Cylinder/Tank Rental Charges
- Bulk Evaporative Loss
- Handling and Labor Costs
- Extra Site Liability Insurance
By contrast, a GN2 system produces nitrogen gas at a cost of $0.131 to $0.320 per 100 cubic feet. These costs vary due to local power rates, compressor efficiency, maintenance expenses, and required nitrogen purity levels. A typical GN2 system achieves a return on investment (ROI) within 6 to 18 months, making it a highly attractive option financially, especially when considering the 75% to 92% reduction in nitrogen costs.
How Nitrogen is Generated
The earth's atmosphere is made up of about 78% nitrogen and 21% oxygen. When atmospheric air is compressed, its pressure increases, but the proportion of nitrogen and oxygen remains unchanged.
In the GN2 nitrogen generator, the compressed air is filtered and dried before passing through a bed of Carbon Molecular Sieve (CMS). The CMS selectively adsorbs oxygen molecules, allowing the larger nitrogen molecules to pass through. The oxygen is trapped in the CMS bed, while a high-purity stream of nitrogen is released from the generator.
When one CMS bed reaches its adsorption limit, the system switches to a second bed, allowing the first to regenerate. This cycle, known as Pressure Swing Adsorption (PSA), creates a continuous flow of high-purity nitrogen gas.
