What Is Nitrogen?

As the most commonly found gas in the atmosphere, nitrogen (N2) is readily available and can be used for a range of industrial purposes. Because nitrogen is an inert gas that reacts slowly with other substances, it’s ideal for situations where you need to prevent either slow or rapid oxidation. This gas is also often used in the food and beverage industries due to its colorless, tasteless and odorless nature.

What Is a Nitrogen Generator?

A nitrogen generator separates nitrogen molecules from compressed air so that users can achieve a flow that is nearly 100% pure nitrogen. These machines can generate varying purity levels of nitrogen, allowing users to tailor their nitrogen supplies to their product or process needs.

A nitrogen generation system allows access to nitrogen on-site, which is excellent for companies that require nitrogen as an essential part of their business processes. Additionally, nitrogen generators don’t present the same safety risks as handling nitrogen cylinders, contributing to a safer work environment.

How Do Nitrogen Generators Work?

A nitrogen generator takes compressed air and separates the nitrogen and oxygen molecules found in the air from each other. This separation of nitrogen and oxygen results in a supply of pure nitrogen. The generator is connected to a compressor and is typically a membrane nitrogen generator or a pressure swing adsorption nitrogen generator.

The nitrogen purity level you need will determine what type of nitrogen generator you should use. A membrane nitrogen generator works well for applications like inflating tires, which require low nitrogen purity. If you need high nitrogen purity for food and beverage processes, a pressure swing adsorption nitrogen generator is a more suitable option.

Nitrogen Generators vs. Nitrogen Cylinders

Those working with nitrogen are likely aware of nitrogen cylinders as one of the most popular ways to supply the gas. How do nitrogen generators differ from cylinders? Why is a nitrogen generator system more suitable for certain applications?

  • Longevity of supply: If you require a high-volume or consistent nitrogen supply, nitrogen cylinders may not be the best option, as their supplies can be depleted quickly. In comparison, on-site nitrogen generators can continually supply nitrogen.
  • Space: Purchasing nitrogen cylinders means you need to dedicate a large amount of space to cylinder storage. If your building lacks the space to properly store nitrogen cylinders, investing in a generator can be a space-saving option.
  • Safety risks: In terms of safety, nitrogen cylinders are heavy and can be challenging to maneuver, posing safety risks, especially when staff aren’t trained on how to move them properly. Operating a nitrogen generator is a safer task that requires no heavy lifting.
  • Associated costs: Continually purchasing and refilling nitrogen cylinders can be a notable business expense. In comparison, investing in permanent equipment like a nitrogen generator can be a sounder financial approach in the long run.

Benefits of Nitrogen Generators

If you’re considering a nitrogen gas generation system for your business but are debating whether it’s worth it, consider some of the most significant benefits of nitrogen generators:

  • Cost efficiency: Generally, nitrogen generators offer reduced operational costs compared to conventional nitrogen supplies. The nitrogen itself often also costs less per cubic meter because of its variations in purity. When users have more control over their purity levels — and don’t have to pay for unnecessarily pure nitrogen for their applications — they can enjoy cost savings.
  • Reliability: All nitrogen cylinder supplies deplete eventually, and waiting for a new supply can decrease productivity on your production line or in other processes. Using a nitrogen generator means your supply won’t run out, so you can enjoy supply assurance and increased productivity.
  • Positive environmental impact: Some nitrogen cylinders cannot be reused, so they’re disposed of after their supply is depleted. Other types of nitrogen cylinders can be refilled and reused multiple times, but they will also be disposed of eventually. Choosing a nitrogen generator can drastically cut down on material waste and result in lower emissions, especially compared to nitrogen delivery services.
  • Product integrity: Because nitrogen minimizes oxidation, it preserves packaging and the products in it without compromising their flavor or reducing their shelf life. Packaging with a nitrogen gas generation system is easier and more accessible.
  • Time savings: If a business relies on external vendors for their nitrogen cylinders, unexpected delays on the vendor’s end could impact the business’s productivity and potentially lead to financial loss. A nitrogen generator eliminates potential vendor issues and helps the company save time.

Industrial Applications of Nitrogen Generators

Here are a few industry sectors where nitrogen generators are especially useful:

  • Food and beverage: Since nitrogen is often used to preserve food and beverages, nitrogen generators can be beneficial for food and beverage producers to keep a steady supply of nitrogen. For example, companies can use nitrogen generators to add nitrogen to chip bags and prevent the bags from collapsing. Overall, nitrogen allows for quality improvement and extends the shelf life of food products.
  • Pharmaceutical and medical: Like the food and beverage industry, nitrogen is commonly used in pharmaceutical packaging, and generators can improve efficiency. This gas can also compress and incapsulate tablets. One of the biggest benefits of nitrogen in the medical industry is that it keeps products dry and sterile, improving their durability and safety.
  • Electronics manufacturing: Since oxygen can cause oxidation in electronic products, nitrogen can be used during production to create an inert atmosphere that prevents oxidation in the soldering process.

Depending on your industry, nitrogen could be essential to your daily processes, and a nitrogen generator provides a cost-effective, flexible and sustainable solution for nitrogen supplies.

How Does a Nitrogen Generator Work? - CHAMCO

Nitrogen generators are an excellent option for on-demand generation of nitrogen on-site.

Their streamlined design and enhanced functionality allow businesses to produce high-purity nitrogen right where needed, minimizing dependency on external suppliers and reducing logistical hurdles.

But do you know how a nitrogen generator works?

In this article, we’ll explain how nitrogen generation technology functions and discuss the factors you must consider when implementing a nitrogen gas generation system to produce nitrogen for your facility.

The Power of a Nitrogen Generator

A nitrogen generator is an efficient machine designed to seamlessly integrate into your existing setups.

At Chamco, we supply compact, plug-and-play nitrogen generators that utilize Pressure Swing Adsorption (PSA) technology. PSA nitrogen generators employ adsorbent materials to filter out oxygen and other impurities, effectively allowing only nitrogen to pass through.

Nitrogen generators are available in sizes to suit businesses of all scales, from small to large, ensuring that even smaller operations can enjoy the benefits of consistent, on-site nitrogen supply.

These systems are versatile and customizable solutions that meet the specific requirements of different industries including laser facilities, food packaging, breweries, electronics, and pharmaceuticals, among others.

The Requirements to Set up an On-Site Nitrogen Generation System

A nitrogen generation system requires a compressor and dryer for operation. If your existing compressor and dryer setup has sufficient capacity, you only need to incorporate the nitrogen generator and buffer tank to complete your setup, ensuring a streamlined process for high-purity nitrogen production.

The Nitrogen Generation Process

Source: PEAK Scientific

So let’s break it down. Here is the nitrogen generation process in a PSA nitrogen generation system.

Step 1: Air Intake

The process starts by drawing in ambient air, which is composed of approximately 78% nitrogen, 21% oxygen, and trace gases from the surroundings.

Step 2: Compression

The incoming air is compressed using an air compressor.

Step 3: Pre-Filtration

Compressed air undergoes pre-filtration before entering the PSA unit, and filters remove dust, moisture, and oil to protect the adsorbent material.

Step 4: Adsorption (Nitrogen Separation)

Compressed air is fed into the dual-pressure CMS vessels and undergoes a cycle of compression and decompression, during which oxygen is absorbed and nitrogen is passed downstream.

This not only delivers continuous nitrogen gas flow rates on a large scale, it also guards against abrasive breakdown, preventing gas supply contamination and ensuring an expected CMS lifespan of up to 20 years.

Step 5: Nitrogen Collection

The process tank ensures there are no large spikes in demand from the system. The nitrogen-enriched gas from the adsorber is collected and supplied to the application via distribution lines at various points within the facility. The generator is sized specifically to the flow rate needed, and, much like water from a faucet, nitrogen is supplied as and when needed.

The purity of the nitrogen ranges from 95% to 99.%will depend on the specific adsorbent material and system design.

What to Consider Before Installing an On-Site Nitrogen Gas Generator

If you’re considering implementing an on-site nitrogen generation system in your facility, there are a few things to consider:

The Purity Required

The purity level required depends on your industry. For example, a laboratory-based application may require ultra-high-purity nitrogen at 99.% purity, while a brewery or chemical plant that is just purging for safety to reduce flammability or reduce oxygen content might need 99.5% purity.

Current Nitrogen Flow Rate

Again, this depends on the industry and the types of machines and processes within your facility. The current flow rate can easily be calculated by looking at your consumption and dividing it by the number of hours you’re operating.

The Pressure Required

Pressure is another parameter that varies depending on the industry and application. For instance, some nitrogen generators can deliver up to 130 psi, which suits various applications—from laboratory environments and food and beverage packaging to brewery purging processes. However, high-pressure applications, such as laser cutting, demand higher pressures, around 400 psi.

The Residual Demand in the Existing Compressor

Compressed air is required to operate an on-site nitrogen generation system, so it’s important to decide whether you need to upgrade or change your existing air compressor to facilitate the addition of the nitrogen generator.

If your operation relies on a bulk tank, you might not have an air compressor if the nitrogen is fed directly into your machinery through a regulator that adjusts the pressure as needed. In such cases, integrating a nitrogen generator would necessitate acquiring an air compressor to provide the necessary compressed air for nitrogen production.

On the other hand, if your facility already has an air compressor, the key question becomes whether it has the spare capacity to support the additional demand from the nitrogen generator.

Current Nitrogen Spend

Understanding your current expenditure on nitrogen is crucial when considering an on-site nitrogen generation system, as it directly influences the decision-making process by highlighting the potential return on investment (ROI).

For instance, if you’re spending $45,000 annually on nitrogen and the complete system costs $140,000, the investment pays for itself in just under two years. Given the system’s lifespan of 15 to 20 years, the investment will offer significant long-term savings compared to a lower annual spend that may not justify the upfront cost of the generator.
