How On-Site Nitrogen Generation Works: A Step-by-Step Guide

In many industrial and manufacturing settings, maintaining a reliable supply of nitrogen is essential. An on-site nitrogen generator allows you to produce nitrogen gas right at your facility, eliminating the need for tank and N2 cylinder deliveries. Below, we’ll break down exactly how on-site nitrogen generation works, step by step, and highlight its benefits for your operation.

What Is an On-Site Nitrogen Generator?

An on-site nitrogen generator is a system that separates nitrogen from ambient air and delivers it at a specific purity, pressure, and flow rate. Instead of depending on nitrogen deliveries, these systems generate nitrogen gas on demand using compressed air as the feed source.

The two primary technologies used for on-site nitrogen generation are Pressure Swing Adsorption (PSA) and membrane separation. Both systems deliver consistent nitrogen output, but each functions differently depending on purity requirements, operating costs, and maintenance needs.

Why Choose On-Site Nitrogen Generation?

There are several compelling reasons businesses across industries are switching to on-site nitrogen generation. Once installed, operating costs are significantly lower than recurring cylinder or bulk delivery expenses. Nitrogen is always available on demand, ensuring uninterrupted operations even during supply chain delays. Producing gas on-site also minimizes waste because nitrogen is generated as needed, not stored and discarded. These systems are compact, freeing up valuable floor space, and they’re safer and more environmentally friendly by reducing truck deliveries and emissions. Lastly, modern nitrogen generators feature built-in analyzers that allow you to maintain precise nitrogen purity levels for your applications.

Step-by-Step: How On-Site Nitrogen Generation Works

Step 1: Air Preparation

The process starts with compressed, dry, and clean air. The air passes through filters that remove particulates, oil vapor, and moisture. High-quality feed air ensures longer system life and consistent nitrogen output.

Step 2: Pressure Regulation

The clean air is adjusted to the operating pressure needed for nitrogen separation. Proper pressure control ensures steady flow and optimal purity.

Step 3: Nitrogen Separation

This is the core of the system, where nitrogen is separated from oxygen and other gases using either PSA or membrane technology.

In a Pressure Swing Adsorption (PSA) system, air enters a vessel filled with carbon molecular sieve (CMS). Oxygen molecules are adsorbed while nitrogen passes through as product gas. When the adsorbent becomes saturated, the vessel depressurizes and regenerates while a second vessel takes over. This cycle continues to provide a consistent flow of high-purity nitrogen gas. PSA systems are ideal for industries that require very high nitrogen purity levels.

In a Membrane Separation system, compressed air passes through membrane fibers that selectively allow oxygen, carbon dioxide, and water vapor to pass through more quickly than nitrogen. The nitrogen remains as the primary output, creating a continuous stream of gas suitable for moderate-purity applications..

Step 4: Purity Monitoring

An oxygen analyzer continuously measures nitrogen purity to ensure the gas meets your specified standards. If oxygen levels increase beyond the set limit, the system automatically adjusts flow or timing to maintain consistency.

Step 5: Delivery to Application

The purified nitrogen is delivered directly to process lines, storage tanks, or other end-use points. Because the system operates on-site, nitrogen is always available without the downtime or logistics associated with deliveries.

Step 6: Venting and Regeneration

In PSA systems, oxygen-rich exhaust gases are vented safely to the atmosphere during regeneration. This allows the adsorbent material to be reused in the next cycle. Proper venting design ensures safe and efficient operation.

Step 7: Maintenance and Optimization

Routine maintenance keeps the system performing at peak efficiency. This includes replacing filters, checking for leaks, calibrating sensors, and monitoring performance metrics. With proper care, nitrogen generators can operate efficiently for decades.

PSA vs. Membrane Nitrogen Generators

Both PSA and membrane nitrogen generators have unique strengths depending on your purity needs and application. PSA nitrogen generators can achieve extremely high purity levels—up to 99.999%—making them ideal for industries like electronics, pharmaceuticals, and metal processing. They have more complex components and require a bit more maintenance but deliver the highest performance where precision matters most.

Membrane nitrogen generators, on the other hand, provide purities up to around 99.5% and are simpler, more compact, and energy-efficient. They’re excellent for applications where moderate purity levels are sufficient. With fewer moving parts and straightforward operation, membrane systems are an economical, low-maintenance solution for continuous nitrogen supply.

Real-World Process Overview

Installing an on-site nitrogen generator typically begins with assessing your facility’s nitrogen demand, including desired flow rates, purity levels, and pressure requirements. The generator modules are then installed and connected to your compressed air and power systems. Once operational, sensors are calibrated, and the system begins its separation cycle. Operators can monitor purity and make adjustments as needed, while ongoing maintenance keeps performance optimized for years to come.

Environmental Impact: On-Site Nitrogen Generation vs. Delivered Nitrogen

As businesses look for ways to reduce their carbon footprint and operate more sustainably, the choice of how you source industrial gases matters. Nitrogen is essential across industries—food packaging, electronics manufacturing, pharmaceuticals, and more—but how you get your nitrogen can make a significant environmental difference.

Here’s a closer look at the environmental impact of on-site nitrogen generation compared to delivered nitrogen, and why producing your own nitrogen often proves to be the greener choice.

Understanding the Two Options

Traditionally, companies have relied on delivered nitrogen—either in high-pressure cylinders or as nitrogen transported in large tanks. While this approach may seem convenient, it involves energy-intensive production at off-site plants and significant transportation to get the gas to your facility.

By contrast, an on-site nitrogen generation system produces nitrogen directly from ambient air using membrane or PSA (Pressure Swing Adsorption) technology. Instead of relying on repeated deliveries, you generate only the nitrogen you need, exactly when you need it.

Lower Carbon Footprint from Reduced Transportation

One of the biggest environmental advantages of on-site generation is the dramatic reduction in transportation emissions. Delivered nitrogen requires frequent truck deliveries to your facility—sometimes multiple times per week—each trip burning fuel and producing greenhouse gases. On-site systems eliminate these recurring deliveries. Fewer trucks on the road mean lower CO₂ emissions and less wear on local infrastructure.

Energy Efficiency and Reduced Waste

Large plants that produce nitrogen consume vast amounts of energy to generate nitrogen gases. Every liter of nitrogen delivered to your site represents a significant upfront energy cost. On-site nitrogen generators, especially modern PSA and membrane systems, typically use only the energy needed to compress and separate the air. This localized process is far less energy-intensive overall.

Additionally, delivered nitrogen often involves partial cylinder returns or product loss from venting, which wastes both nitrogen and the energy used to produce it. Generating nitrogen on-site produces only what you use, helping eliminate unnecessary waste.

Smaller Environmental Footprint from Packaging and Handling

Delivered nitrogen requires cylinders, pallets, protective wrapping, and other packaging materials—many of which have limited reuse cycles and eventually end up as waste. With an on-site nitrogen generation system, these materials are no longer part of your supply chain. That translates to less landfill waste and fewer resources consumed in manufacturing and recycling cylinders or tanks.

Improved Sustainability for Your Operations

For companies pursuing sustainability goals or environmental certifications, reducing your nitrogen supply chain footprint can make a measurable difference. On-site nitrogen generation supports greener operations by minimizing fuel use, cutting greenhouse gas emissions, and lowering the embodied energy in every cubic foot of nitrogen you consume.

Long-Term Cost and Environmental Benefits

Beyond environmental gains, on-site nitrogen generation typically lowers operating costs over time. By eliminating recurring delivery fees, rental charges, and cylinder management, your company can reduce expenses while advancing its sustainability commitments. The investment in an on-site generator pays off both financially and environmentally.

What Is a Nitrogen Generation System and How Does It Work?

Across many industrial, manufacturing, food, and research applications, a nitrogen generation system is a backbone utility: it delivers a continuous supply of nitrogen gas exactly on-site, on-demand. Whether you’re preserving freshness in packaging, maintaining inert atmospheres for welding or brazing, or ensuring safety in oxygen-sensitive processes, using an in-house nitrogen generation system can offer reliability and cost savings that bottled or delivered gas often cannot match.

In this article, we’ll explain what a nitrogen generation system is, explore how nitrogen generation systems work, and show you the main types and benefits of installing one.

What Is a Nitrogen Generation System?

A nitrogen generation system (also called a nitrogen generator) is a setup that extracts nitrogen gas from the ambient air, purifies it to a required purity level, and delivers it for use in-house. Instead of ordering nitrogen in cylinders or bulk deliveries, the system makes nitrogen continuously at your facility, customized to your usage rate and purity needs.

Key components typically include a source of compressed air, filters and dryers to remove moisture, particulates, and oil, the separation module where nitrogen is isolated, and controls, safety features, and sometimes storage or buffer tanks.

How Does a Nitrogen Generator Work?

There are multiple technologies for separation, and each nitrogen generation system might use one or more different methods depending on required purity, flow rate, pressure, and cost. Two of the most common technologies are PSA (Pressure Swing Adsorption) and membrane separation.

PSA systems pass compressed air through vessels filled with an adsorbent like carbon molecular sieve. Oxygen, along with CO₂ and water vapor, is adsorbed under high pressure while nitrogen passes through. The pressure is then released so the adsorbent regenerates, and the cycle alternates between two or more vessels to provide continuous output. PSA can deliver very high purity levels, often exceeding 99%.

Membrane systems push compressed air through a membrane that allows oxygen and water vapor to pass through faster than nitrogen. The slower nitrogen flow is collected as product gas. While membrane systems typically achieve 95–99% purity, this is often sufficient for many industrial applications.

Here is a step-by-step summary of how a typical PSA nitrogen generation system works:

  1. Air intake & compression – Ambient air is drawn in and compressed to a target pressure.
  2. Pre-treatment – Filtration, drying, and cooling remove moisture, oil, dust, and CO₂.
  3. Adsorption – Cleaned, compressed air enters a vessel filled with carbon molecular sieve. Oxygen and other unwanted components are captured while nitrogen passes through as the product.
  4. Switching / Desorption – Once the adsorbent becomes saturated with oxygen, the system directs air to another vessel while the saturated vessel regenerates by reducing pressure, releasing the oxygen.
  5. Purity control & buffering – Sensors monitor nitrogen purity, and buffer tanks or storage smooth out fluctuations in demand.
  6. Delivery – Purified nitrogen is delivered to the point of use or stored if needed.

Types of Nitrogen Generation Systems

Different configurations suit different needs. Options include turnkey PSA generator systems, membrane nitrogen generators for lower-purity applications, custom engineered systems for unique requirements, containerized or modular systems for portable operations, and cylinder-filling systems for facilities that want to fill their own nitrogen cylinders.

Why Choose a Nitrogen Generation System?

Key benefits include cost savings compared to bottled or bulk nitrogen, supply reliability with independence from delivery schedules, the ability to set and maintain exact purity levels, and operational flexibility to match changing demand. Additional advantages include fewer safety and handling risks and a reduced environmental footprint thanks to less transportation and packaging waste.

The good news is that modern nitrogen generation technologies are designed to maximize efficiency while maintaining purity and performance.

Why Energy Efficiency Matters in Nitrogen Generation

Operating a nitrogen generator around the clock can be energy-intensive if not properly optimized. Inefficient systems waste electricity, increase carbon footprints, and raise overall operating costs. For facilities where nitrogen is critical—such as food packaging, electronics, metal fabrication, and healthcare—improving energy efficiency has a direct impact on both profitability and sustainability goals.

Energy-Efficient Nitrogen Generation Technologies

The latest advancements in on-site nitrogen generators focus on lowering energy use without sacrificing gas purity. Here are some key technologies:

  • PSA (Pressure Swing Adsorption) Optimization
     PSA nitrogen generators can be designed with advanced adsorption materials that increase nitrogen yield per cycle, reducing the energy required for each cubic foot of nitrogen produced.
  • Membrane Separation Systems
     Membrane nitrogen generators operate without moving parts, making them inherently more energy-efficient for applications that require moderate purity levels.
  • Variable-Speed Compressors
     By adjusting output to match demand, variable-speed air compressors prevent unnecessary energy consumption during low-usage periods.
  • Smart Monitoring & Controls
     Integrated sensors and automated controls ensure nitrogen production is aligned with real-time demand, avoiding overproduction and wasted energy.

Practical Tips for Improving Nitrogen Generation Efficiency

Even the most advanced technology benefits from best practices. Facilities can boost energy efficiency with these steps:

  • Regular Maintenance – Clean filters, check valves, and service compressors to ensure the system operates at peak performance.
  • Right-Sizing the System – Choose a nitrogen generator that matches your actual consumption. Oversized systems waste energy by producing excess gas.
  • Optimize Purity Levels – Higher purity requires more energy. Select the purity level your application truly needs—no more, no less.
  • Heat Recovery – Reclaim waste heat from compressors and reuse it for facility heating or other processes.
  • Leak Detection – Even small air leaks in the system force compressors to work harder, wasting energy. Regular leak audits keep efficiency high.

When you purchase a nitrogen system from On Site Gas Systems, we ensure that your nitrogen system will produce nitrogen at the purity and rate you require. If your business needs a custom nitrogen generator, we can help.

The Basics: How Nitrogen Generators Work

Nitrogen generators come in two types: pressure swing adsorption (PSA) nitrogen generators and membrane nitrogen generators. Both types of generators require a source of compressed air. When the compressed air enters the nitrogen generator, the nitrogen separates from other gases. These gases are expelled from the generator, while nitrogen comes out in a steady, continuous stream.

Compared to bulk or cylinder nitrogen delivery, on-site nitrogen generation is beneficial in many ways.

  • Eco-friendly: On-site nitrogen generation is environmentally friendly. Nitrogen generators use little energy and do not rely on fossil-fuel-dependent vehicles for periodic transportation.
  • Low-cost: Nitrogen generators cost little money to operate every month. After the initial up-front cost, nitrogen generators have a low cost.
  • Reliable: Nitrogen generators are far more reliable than cylinder delivery, which can be affected by supply chain disruptions. Businesses with nitrogen generators enjoy a continuous supply of nitrogen whenever needed.
  • Unlimited supply: Nitrogen generators produce an unlimited supply of nitrogen. This allows businesses to scale their production up or down as needed.

Why Customization is Critical in Certain Industries

Customized nitrogen system design is critical in some industries because purity, flow rate, and pressure demands vary from one business to the other. Each industry also has its own environmental, spatial, and regulatory challenges.

Why PSA Nitrogen Generators Are the Industry Standard

Nitrogen plays a vital role in many industrial processes, so nitrogen generation is important in many industries. If your business uses nitrogen, either for manufacturing or other reasons, then it’s important to find a reliable source of nitrogen.

There are several different types of nitrogen generators that your business can choose from, including PSA (Pressure Swing Adsorption) nitrogen generators. PSA nitrogen generators provide high-purity nitrogen to businesses of all kinds.

If your business needs a nitrogen generator, pressure swing adsorption nitrogen generation can help your business obtain high-purity nitrogen at an affordable price.

Understanding PSA Nitrogen Generation

PSA nitrogen generators have two tanks that each contain a carbon molecular sieve. The generator fills one tank with air, then increases pressure inside the tank. The carbon molecular sieve adsorbs oxygen and other molecules.

Once the nitrogen has been separated from the various types of gas in the tank, the pressure swing adsorption nitrogen generator produces a high-purity stream of nitrogen. The other gases are ejected from the tank. PSA nitrogen generators have two tanks that alternate between pressurizing and depressurizing (this is the pressure swing process), allowing the generator to produce a continuous supply of nitrogen. Compared to other ways of obtaining nitrogen, such as cryogenic separation, PSA nitrogen generators have many advantages. 

  • They are more convenient than cryogenic nitrogen production.
  • It costs less over time when compared to nitrogen obtained through cylinders.

If your business could benefit from nitrogen generators, talk to On Site Gas Systems to learn more about whether PSA nitrogen generators can meet the unique needs of your business.

The Benefits of PSA Nitrogen Generators

There are many benefits to using a PSA nitrogen generator. Knowing the benefits can help you decide whether this type of nitrogen generator will work for your business.

1. High Purity Nitrogen Production

PSA nitrogen generators produce high-purity nitrogen (up to 99.9999%). This makes PSA nitrogen generators critical for applications that require high-purity nitrogen.

2. Cost-Effective and Energy-Efficient

PSA nitrogen generators have lower operating costs compared to traditional nitrogen delivery methods, such as cylinders and liquid nitrogen. They require little energy to run and, therefore, cost little money to operate.

3. Reliable and Continuous Nitrogen Supply

The use of a PSA nitrogen generator eliminates supply chain delays and reliance on third-party nitrogen suppliers. PSA nitrogen generators offer on-demand nitrogen production for various industrial applications.

4. Versatility Across Industries

PSA nitrogen generators are used in many industries, including:

  • Food & beverage industry – PSA nitrogen generators play an important role in packaging and food preservation.
  • Pharmaceuticals – Nitrogen creates an inert environment to aid in drug production and packaging.
  • Electronics & manufacturing – The use of nitrogen in electronics and manufacturing helps prevent oxidation during the soldering process.
  • Aerospace & automotive – Nitrogen is used in tire inflation and fuel system inerting in the aerospace and automotive industries.

5. Reduced Environmental Impact

For businesses that prioritize sustainability in their operations, PSA nitrogen generators are highly energy efficient. Whereas nitrogen cylinders rely on vehicles that use fossil fuels to operate, PSA nitrogen generators do not. This makes them the “green” choice for businesses.

In addition to eliminating emissions associated with nitrogen transportation, pressure swing adsorption nitrogen generation is a more sustainable solution compared to cryogenic nitrogen production.
