ON-SITE Nitrogen Generation

Significantly reduce your nitrogen gas costs


Nitrogen gas generation is simply the process of separating air gases. Air is comprised of 78% nitrogen, 21% oxygen and 1% trace gases. The process utilizes a line of compressed air and state of the art gas separation technology to isolate and concentrate the nitrogen molecules from the air, while safely disposing of the oxygen and trace gas.
Most nitrogen gas generation systems will offer a payback period of 6 to 18 months and provide an annual return of investment of up to 90%. The project payback and return on investment for each project will vary and is highly dependant on the nitrogen flow, pressure and purity requirements of the application. Every project is an engineered solution, designed to satisfy the specifications of the industry and application. It is important to consult with a professional who can offer a non-intrusive preliminary assessment to help determine project viability, payback and roi.

When speaking about nitrogen, the term purity refers to the level of gas concentration.  A common misconception when discussing nitrogen purity, is that it refers to the presence of contaminants, such as particulate matter and oil vapour. While filtering these contaminants is highly critical, it should not be confused for purity when speaking about nitrogen.

Our solutions are engineered to produce nitrogen gas ranging from 95% to 99.999% purity. One of the core benefits of nitrogen gas generation is the ability to produce nitrogen at the purity the application truly requires, often creating tremendous cost reduction opportunities for the user. A higher tolerance for remaining oxygen content will result in lower capital and operating costs of the system.

Yes, nitrogen gas generation is very safe and can be a substantial contribution to a company’s health and safety initiatives. Onsite nitrogen generation removes the requirement for employees to work with liquid nitrogen at a temperature of -196°C, or handle gas cylinders pressurized to 4,500psi, both of which can be extremely dangerous. Nitrogen gas generation systems are designed to safely produce nitrogen, in gaseous state, on demand.

Nitrogen generation is the most cost effective way of procuring nitrogen gas. When purchasing nitrogen in conventional liquid and bottled supply, the buyer has to pay for transport, storage, rental, compliance, handling and many other charges, in addition to the stated price of nitrogen gas. All of these additional charges need to be considered when calculating the cost per m3 of nitrogen.

Once a nitrogen generation system is installed, the only costs of operation are electricity to power the system and equipment maintenance. The sum of these two values is what determines the cost per m3.

Typical price ranges of varying nitrogen supply types in the North American market are as follows:

  • Bottled Gas (most expensive) $3.00 – $15.00 per m3
  • Liquid dewar (more expensive) $1.50 – $3.00 per m3
  • Liquid bulk tank (expensive) $0.40 – $1.50 per m3
  • Nitrogen gas generation (least expensive) $0.005 – $0.09 per m3
    • Price per m3 is dictated by application requirements
