ON-SITE Nitrogen Generation

Significantly reduce your nitrogen gas costs

Purity Nitrogen Generator

Nitrogen Generators

Nitrogen is all around us. It is one of the most plentiful elements in our galaxy and accounts for 78% of the atmospheric air that we breathe. On site nitrogen gas generators simply separate and concentrate the nitrogen molecules in the air, while disposing of the oxygen and trace gases. The delivery process is on-demand, meaning you can generate as much or as little nitrogen gas as you require at any given time. Each application and industry will require varying nitrogen concentration levels, referred to as purity. The ability to control the purity, along with pressure and volume, is what drives such a rapid payback and exceptional ROI.

When evaluating technology options, it is crucial to understand how the system configuration, technology types and equipment design factors will impact the capital purchase price and operating costs of the system. A well-aligned technology and application synergy will tremendously reduce nitrogen expenses and ultimately contribute to the profitability of a business. Ineffective system design and misapplied technology can unnecessarily increase the capital cost of a system and also the cost of ownership by up to 800%.  When evaluating nitrogen gas generation for any application, it is critical to consult with a team who can quantify the impact of the technology selection and system design.

What to consider when evaluating technology options?

On site nitrogen gas generation can be achieved through pressure swing adsorption (PSA), or membrane separation technology.  The selection of which technology to apply will vary by industry and is highly dependent on how the nitrogen gas is being used.  Our design engineering process delivers the lowest cost of operation today, while allowing for future system expansion without compromising efficiency.

Pressure Swing Adsorption (PSA)

PSA is a process in which compressed air is passed through a bed of carbon molecular sieve (CMS), which is stored in multiple chambers, side by side. The CMS is an adsorbent material designed to capture the oxygen and trace gas molecules in its pores, while allowing the larger nitrogen molecule to flow past the CMS and out of the nitrogen generator for process use.

The PSA nitrogen generator is a self-regenerating system, meaning it cleanses itself of waste gas impurities without human interaction. The nitrogen generator is divided into two chambers: side A and side B.  These chambers will work in tandem to separate the gases, regenerate the spent CMS and equalize system pressure. While chamber A of the nitrogen generator is online, actively separating the nitrogen from air, chamber B is offline in regeneration mode, preparing for gas adsorption duty.  The chambers will continuously alternate gas separation and regeneration duties, providing a stable and uninterrupted flow of nitrogen gas at extremely high purity and uncapped flow rates.

A well designed system can offer a payback period of 6-18 months, with a 90% reduction in annual Nitrogen Expense

Hollow Fiber Membrane

Hollow Fiber Membrane

Nitrogen generation can be achieved using membrane technology.  Similar to pressure swing adsorption (PSA), nitrogen is isolated from the other air gases using a separation process.  Membrane separation is achieved by passing compressed air through thousands of hollow fibers, which are designed to separate nitrogen from oxygen and trace gases.  While the compressed air travels down the hollow fibers, the oxygen and trace gases will permeate through the fiber walls, allowing only nitrogen continue down the fiber tubes and out of the discharge port.  This separation process is called selective permeation. Hollow fiber membrane technology is a great solution for low flow and purity applications, where space and electricity are limited.
