Nitrogen Generators

Onsite nitrogen generators are a highly cost-effective and reliable solution in most industrial applications where nitrogen gas is used. They reduce the need to spend time and money on ordering and transporting nitrogen gas tanks or bulk liquid nitrogen, increase employee safety, and ensure a more efficient operation since they provide 24/7, onsite access to nitrogen. The two main types of nitrogen generators are Pressure Swing Absorption (PSA) generators and Membrane nitrogen generators, each designed to meet specific purity, flow rate, and operational requirements.

Types of Nitrogen Gas Generation Technologies

Advanced Gas Technologies offers a full range of PSA and membrane type nitrogen generation technologies, engineered for reliability, energy efficiency, and long-term performance. Our nitrogen generation technologies cover a wide range of flow capacities from less than 1 m3/hour (40 SCFH) to large tonnage nitrogen plants suitable for refining, chemical processing, and other high-flow volume applications.

Membrane Type
Nitrogen Generators

Membrane nitrogen generators use advanced hollow-fiber, polymeric membranes to efficiently filter oxygen from a dry compressed air stream to produce gaseous nitrogen. The purity of nitrogen can be adjusted, which makes it ideal for applications where the purity requirement is below 99.5%. Membrane technology is a sustainable, low maintenance, and efficient way to produce nitrogen. Membrane nitrogen generators are also compact and easy to install, making them a highly economical option for businesses of all sizes.

Modular PSA Nitrogen Generators

For lower nitrogen flow requirements, Advanced Gas Technologies can offer a truly modular, field expandable PSA nitrogen generator. These systems are ideal for smaller operations that have high growth aspirations. Adding a second selective soldering to your electronics manufacturing operation? Adding a second MAP line to your food packaging operation? No problem. We have you covered. We can add additional modules in the field to your nitrogen generator and have you up and operating with increased nitrogen generation capacity in a matter of hours!

Standard Twin Tower Nitrogen Generators

For higher nitrogen flow requirements, Advanced Gas Technologies' line of standard twin tower nitrogen generators are the most energy efficient on the market. Based on an electricity cost of $0.07 USD per kW/h, ultra-high-purity nitrogen (99.999%+) can be produced on site for a little as $0.10 USD per 100 CF (< $0.04 per M3). Depending on nitrogen purity requirements, system capacities of over 100 tons per day of nitrogen production are available with a single equipment train. Multi-train systems c/w energy efficient turn-up and turn-down capabilities are available for higher capacity requirements.

The Benefits of an Onsite Nitrogen Generating System

The benefits of generating your own nitrogen include:

Cost Savings

Factors like fluctuating conventional nitrogen supply prices and delivery location will impact what you spend if you have nitrogen delivered to your facility. When you shift to onsite nitrogen generation, you can substantially reduce these costs no matter where you are located. In fact, you can see a return on investment in a little as nine to 24 months.

Increase Safety for Employees

Employee safety is paramount in any industrial environment. Onsite nitrogen generation significantly reduce the risk of worker injury. Handling nitrogen cylinders, tank leaks and exposure to liquid nitrogen through delivery and unloading is 100% eliminated, thus creating a safe and reliable system.

Reduce Negative Impact on Environment

By having your own nitrogen generating system, you reduce your environmental impact as you no longer need to use heavy transport trucks to deliver and replenish your tanks. You also increase operational efficiency and improve your reputation in the industry as a company that is environmentally conscious.

Efficient Time Savings

Industrial users who set up onsite nitrogen generation save time on critical operations that use nitrogen. One of the biggest losses for industrial users each year is operational downtime caused by logistical issues with transporting nitrogen from vendor locations. With an onsite nitrogen generating system, critical processes run smoothly because you have a 24-hour supply of high-purity nitrogen gas to run your processes.

How Much Does It Cost to Generate Nitrogen?

Here is a range of costs associated with the various types of conventional sources of nitrogen gas supply in the North American marketplace:

Cylinder / Nitrogen
$3.00 - $15.00 per M3 / $8.00 - $40.00 per 100 CF

Liquid Dewar / Nitrogen
$0.70 - $1.50 per M3 / $1.80 - $4.00 per 100 CF

Bulk Liquid / Nitrogen
$0.12 - $0.75 per M3 / $0.30 - $2.00 per 100 CF

Depending on nitrogen purity required, geographic location and associated electricity costs, typical operating costs (energy and maintenance) for generating nitrogen on site can be less than $0.02 per M3/$0.05 per 100 CF based on nitrogen purities of 95 – 97%.

The typical cost to generate nitrogen on site at a nitrogen purity of 99.5% would be $0.03 - $0.05 per M3 / $0.10 - $0.14 per 100 CF.

Top 5 Industrial Nitrogen Generator Applications

Here are the five most popular nitrogen generator applications in the industrial sector:

Food Packaging (MAP)

Modified Atmosphere Packaging (MAP) with nitrogen and nitrogen-CO2 gas mixes are often used in the food packaging industry to preserve perishable items by preventing spoilage, ensuring freshness, maintaining flavour, and extending the product shelf life. Onsite nitrogen generation is highly beneficial in the food packaging industry to save on costs and maintain a quality product.

Beverage Storage, Transport, and Dispensing

Like the food industry, the beverage industry can also improve its operational efficiency by having onsite nitrogen generating systems. These systems make it more efficient to transport beverages to end users such as juice packagers, vintners, breweries, and other manufacturers of beverage dispensing systems.

Laser Cutting

The success of a laser cutting operation depends on a lean and efficient shop, which is why it is highly beneficial to generate your own nitrogen onsite. Nitrogen shields the metal from oxidation and removes molten material during cutting. Many industrial facilities rely on high-pressure cylinder or bulk liquid nitrogen, which can lead to significant purge losses of up to 20%. An onsite nitrogen generator eliminates these losses entirely.

Electronics Manufacturing and Soldering

High-purity nitrogen is essential in electronics manufacturing, particularly for solder applications such as selective soldering applications, where consistent purity reduces dross and improves solder quality. Nitrogen generators reduce dross formation, lowers surface tension, and allows solder to separate cleanly from the workpiece.

Fuel and Chemical Tank Inerting

The ideal inert gas for blanketing or purging fuel and chemical tanks is nitrogen. Having an onsite nitrogen system will reduce your costs and allow you to have a 24/7 nitrogen supply to meet your requirements.

Other Common Applications for Membrane and PSA Nitrogen Generators

Some of the other applications that are well-suited for onsite nitrogen generating systems techology include:
