It’s Your Money! Investing In Onsite Nitrogen Generation
Nitrogen is available from gas suppliers in multiple delivery forms:
- Bulk liquid
- Liquid dewars
- High-pressure cylinders
Did you know that you can generate nitrogen by extracting it from the ambient air using PSA or Membrane technology?
The benefits of onsite nitrogen generation are numerous, but none are as compelling as the reduction in operating expenses. Annual operating costs associated with onsite nitrogen generation fall into two categories:
- the electricity consumed by the air compressor
- periodic maintenance (changing filters and other consumables)
Of these two, electricity is the most significant annual expense. This cost, however, is relatively nominal in terms of price per unit compared to the cost of purchasing nitrogen from a bulk supplier!
Return On Investment – Purchasing Your Holtec Generator
- ROI – the initial investment in a nitrogen generator is typically paid back in less than one year! This ROI is even more dramatic for high nitrogen prices found in locations that are remote to the supply chain
- Operational flexibility – in addition to the expense of bulk nitrogen, buying it comes with harsh terms, including price increases contractually demanded by the supplier. Contracts are typically 5-10 years or more long and very restrictive. Purchasing nitrogen often comes with charges for tank rental fees, delivery fees, and hazardous material surcharges
- Convenience – nitrogen generated onsite is under YOUR control. If you decide to run a second shift, nitrogen will be available! No need to work through a contract, availability, and pricing details with your bulk supplier
- Reduced safety concerns – onsite nitrogen is typically stored at 5-20x lower pressure than a nitrogen cylinder. Liquid nitrogen is stored at shallow temperatures, which presents a freezing hazard and, when safeties fail, can cause extreme over pressurization of downstream equipment
- Purity control – Bulk nitrogen is typically supplied at ultra-high purity – >99.999% – which is significantly higher than most industrial requirements and demands more electricity to produce. In contrast, onsite nitrogen generators are sized to only produce the flow, purity, and capacity that you require. Smaller, less costly systems can be acquired if purity is customized to your actual needs
- Consumption rates – Pay for what you use! When you are not using nitrogen, your new Holtec nitrogen generator will turn off, consuming no electricity. Liquid nitrogen stored in a bulk tank outside your facility will boil off when not consumed and must be released through a safety valve. Additionally, some suppliers require you to absorb a specific loss rate and may empty your tank to the atmosphere before refilling
