Inerting is a critical safety and process requirement across many industries where flammable, explosive, or oxygen-sensitive environments exist. Traditionally, nitrogen used for inerting has been supplied through high-pressure gas cylinders or bulk liquid nitrogen deliveries. However, with rising operational costs, supply chain challenges, and increased focus on safety and sustainability, on-site nitrogen generation has emerged as a reliable and cost-effective alternative.
What is Nitrogen Inerting?
Nitrogen inerting is the process of reducing or eliminating oxygen in a system by introducing nitrogen gas. By lowering oxygen concentration below the level required for combustion or oxidation, inerting helps prevent:
Nitrogen is ideal for inerting because it is inert, non-toxic, non-flammable, and readily available from atmospheric air.
Why On-site Nitrogen Generation?
On-site nitrogen generation systems produce nitrogen directly at the point of use by separating it from compressed air. These systems eliminate dependency on external nitrogen suppliers and offer continuous, on-demand supply tailored to specific process requirements.
Key Advantages
1. Enhanced Safety
On-site generation removes the need for handling high-pressure cylinders or cryogenic liquid nitrogen. This significantly reduces risks associated with storage, transportation, and manual handling.
2. Cost Savings
After the initial investment, operating costs are substantially lower compared to cylinder or liquid nitrogen supply. Industries typically achieve payback within 12–24 months due to:
3. Continuous and Reliable Supply
On-site systems provide uninterrupted nitrogen availability, ensuring critical inerting processes are never compromised due to supply delays or shortages.
4. Adjustable Purity Levels
Nitrogen purity can be adjusted based on application needs, commonly ranging from 95% to 99.999%. This flexibility allows industries to avoid paying for higher purity than required.
5. Environmentally Friendly
Producing nitrogen on-site reduces carbon emissions associated with transportation and logistics, supporting sustainability and ESG goals.
Technologies Used in On-site Nitrogen Generation
PSA (Pressure Swing Adsorption)
PSA systems use carbon molecular sieve (CMS) to separate nitrogen from oxygen under pressure. They are widely used for industrial inerting due to:
Membrane Nitrogen Generators
Membrane systems separate gases using hollow fiber membranes. They are compact, low-maintenance, and ideal for:
