What Is An Ultra-High Purity (UHP) Nitrogen Generator Used For?

Some industries use nitrogen to achieve their manufacturing objectives. Nitrogen comes in various grades, from low-purity nitrogen and up. Knowing what ultra-high purity nitrogen is used for can help you decide if this type of nitrogen is right for your industrial application.

What is Ultra-High Purity Nitrogen Gas?

Ultra-high purity nitrogen generators (UHP) produce ultra-high purity nitrogen gas. Nitrogen gas can only be ultra-high purity if it exists in concentrations of 99.999% with negligible impurities. Any variation on these specifications may mean that the nitrogen is no longer ultra-high purity.

Oxygen cannot be present in ultra-high purity nitrogen in quantities greater than ten parts per million. And total hydrocarbons cannot be present in ultra-high purity nitrogen in amounts greater than 0.5 per million by volume.

What Industries Use a UHP Nitrogen Generator?

Nitrogen generators are used in a variety of industries. However, not all of these industries require ultra-high purity nitrogen generators. The industries that use ultra-high purity nitrogen generators include:

Metalworking Grade Nitrogen

Laser cutting processes require 99 – 99.999% nitrogen.

Pharmaceutical Industries

Pharmaceutical manufacturing processes require nitrogen because many drugs require high-grade to ultra-high nitrogen with a purity between 97 – 99.99%. Nitrogen is used for nitrogen receptacles, storage tanks, and other equipment and may be used in drug packaging to help medications retain freshness, thereby preventing the active ingredients from deteriorating.

Electronic & Semiconductor Manufacturing

Nitrogen is used in electronics and semiconductor production. This industry requires at least 99.99 – 99.999% nitrogen. A few processes in this industry use lower concentrations of nitrogen.

Do You Need an Ultra-High Purity Nitrogen Generator On-Site?

There are many reasons to get a UHP generator on-site, including:

  • Never run low again. When you rely on nitrogen gas delivery to your facility, there’s always the possibility that your nitrogen gas supply will run low. When you have your own generator, this will never happen.
  • Cost-effective. Delivery charges and other fees associated with nitrogen cylinder delivery can dramatically raise the cost of using nitrogen. Having your own generator keeps costs manageable.
  • Safety. Nitrogen cylinders can be a safety hazard if not properly handled. Using a generator eliminates any risks that may come from using cylinders.
  • Avoid supply issues. Every industry can be affected by supply chain issues – and the nitrogen gas supply chain is no exception. You can avoid these problems when you have a nitrogen gas generator, which keeps your company functioning.
  • Never have a supply delay again. Your supplier of nitrogen gas may experience delays for a variety of reasons. You can avoid this problem with a nitrogen generator.

How Does an Oxygen Generator Work?

Many industries need high purity oxygen for their manufacturing needs. Getting oxygen gas can be expensive and impractical without a dedicated oxygen generator. Knowing how an oxygen generator works can help you decide if this type of generator is right for you.

What is an Oxygen Generator?

An oxygen generator is an application that uses a unique selective adsorption technology to separate the oxygen from the nitrogen and other components in compressed air. The oxygen can flow through sieve that retains any nitrogen, producing high purity oxygen.

Oxygen generators are very similar to nitrogen generators. One way that oxygen generators are different is the material inside the sieve is made from zeolite instead of carbon.

Air channeled through the oxygen generator is separated into the gasses that make up the air. The sieve selectively absorbs the nitrogen with the zeolite, thus allowing the high purity oxygen to flow through the generator and be used in an application, or stored in tanks as needed.

What Are Oxygen Generators Used for?

Various applications can use an oxygen generator, including medical, sewage and wastewater treatment, paper making, food and beverage industries, glass manufacturing, mining, commercial fish farming, metallurgy, gasification processes, and more.

How Do Oxygen Generation Systems Work?

So, how do oxygen generators work? The generator uses an adsorptive tower with zeolite to retain nitrogen while allowing oxygen to pass into a collecting tank. The generator continues functioning until the zeolite sieve has reached full saturation and can no longer absorb nitrogen.

Once the zeolite has fully absorbed as much nitrogen as it can handle, the cylinder is depressurized to release the nitrogen into the atmosphere. This process is regulated by a unit that detects oxygen and nitrogen gas saturation levels.

Oxygen Generator vs. Oxygen Concentrator

The terms oxygen generator and an oxygen concentrator are often used interchangeably, and in general, these terms mean the same thing. Often, the term oxygen concentrator is used to describe a smaller, more portable oxygen generator, while the term oxygen generator is used to describe a large device that produces large quantities of oxygen for industrial use.

What Parts Make Up an Oxygen Generator?

Oxygen generators are generally made up of the following pieces:

  • Particulate and coalescing filters
  • Air compression unit
  • Zeolite sieve
  • Air dryers
  • Single pressure stabilizing reservoir
  • Gas circulation tubing
  • Inlet and outlet valves

Nitrogen Generating Machines: The Cost Benefits of an On-Site N2 Generator Machine

First, what are the main benefits of having an N2 generation machine on site at your facility?

  • Guaranteed Supply – When your company is generating nitrogen, you’re guaranteeing your supply and have the means to minimize downtime.
  • High Safety Standard – Relying on nitrogen cylinders brings with it many dangers and risks that are inherent to this system. Switching to on-site nitrogen generation not only eliminates those risk factors but also raises your company to a higher safety standard.
  • Cost-Efficient – Immediate cost efficiencies are realized including eliminating delivery charges, guessing your future needs to re-order enough volume supply, equipment rental fees, contract fees, and more.
  • Helping the Environment – On-site nitrogen generation reduces your company’s carbon footprint.
  • Made to Fit Multiple Applications – By geography, industry need, and purity level.

Guaranteeing Your Gas Supply with On-Site Nitrogen Generation

Once you begin generating nitrogen on site at your company, you will quickly realize a reduction in downtime as well as have considerably fewer supply issues. For starters, you are guaranteeing your own supply based on real-time needs. Avoid having to guess what you may (or may not) need for future orders – just because your deadline is due.

By eliminating the outside vendor as your source of nitrogen gas, you are also no longer subject to the vendor’s own delays, unpredictable supply chain issues, closings, deadlines, or shortages. When you are generating your own nitrogen gas, you know precisely how much gas you have on any given day, and how much gas you can generate in a day. This means, no more wait times for deliveries, delayed orders, and unnecessary production downtime that is connected to deliveries. Is your company located in a remote geographic area outside of the supplier’s main delivery route? Time to switch to an on-site nitrogen generation, it eliminates the headaches and downtime associated with that, too!

On-site N2 generation boosts your operations and efficiencies, which in turn maximizes productivity.

Higher Safety Standards

Certain dangers are inherent to transporting or storing nitrogen gas cylinders or liquid nitrogen pressurization and cylinders are storing nitrogen at 2200 PSI. All of the risks associated with transporting and storing the nitrogen gas supply are eliminated with on-site nitrogen gas generation.

Realizing Immediate Cost Efficiencies

Investing in an on-site nitrogen generator will quickly yield cost savings and begin increasing efficiencies long term as well. Nitrogen gas can cost anywhere from $0.35 to $1.50 per hundred cubic feet while delivering nitrogen in cylinders can double that cost. The installation of an on-site nitrogen generator can potentially decrease that cost to $0.25 per hundred cubic feet. Add to those savings, the removal of add-on fees for delivering cylinders including hazmat fees, tank rentals, delivery charges, and other miscellaneous fees.

With on-site nitrogen generation, you can generate what you need when you need it instead of guessing the amount of gas required for future delivery.

Environmentally Friendly

It takes a large amount of energy to convert air into nitrogen liquid and then back to a gas. This large volume of energy contributes to polluting the environment. Switching over to on-site nitrogen generation eliminates that step and greatly reduces your carbon footprint – along with being a cost-efficient form of energy production.

Made to Fit Multiple Applications

From chemical manufacturing to pharmaceutical technology and offshore drilling, on-site nitrogen is generated for all of their production needs at different levels. Volume production is adjustable at any purity level for any geographic location.

On Site Gas Systems has made and installed nitrogen generation systems for companies around the globe. We can arrange a free consultation to find out what nitrogen generation machine is best suited for your facility’s needs. Contact us today!

Industrial Nitrogen Generators: How To Choose An Industrial N2 Generator

Several factors are at play when choosing a nitrogen generation system to fit your company’s needs. It is important to consider the possible options for cost savings, portability, and what quantity you will need for the application. To do this, it is best to identify the industrial application that the nitrogen generator will be supplying. It is also good to think about the end result required for the task at hand. Membrane systems and PSA systems are two types of nitrogen generators that produce high quantities of nitrogen. Each one delivers notable volume, and the cost of maintenance and operations is nominal.

Are Nitrogen Generators Cost-Effective?

Producing nitrogen on site provides our clients with substantial savings when compared to the costs associated with purchasing cylinders, bulk, or dewars. The elimination of delivery fees, long-term contracts, tank rental costs, and price increases allow for a fast return on investment. On average, our systems pay for themselves in less than 18-months. Operating costs associated with On Site Gas Systems on-site nitrogen generators are minimal due to limited maintenance and a low air-to-nitrogen ratio.

Membrane Nitrogen Generator

That said, the selection of an industrial nitrogen generator comes down to the quantity of gas required, and the portability needed if necessary. With a membrane nitrogen generator, the separation process does not require moving parts. Membrane nitrogen generators offer several custom configurations and system mobility that other technologies don’t offer. Membrane units are particularly helpful in outdoor environments, for example.

What Nitrogen Purity Does My Application Require?

An N2 system that provides 95% purity takes approximately two standard cubic feet per minute of compressed air to provide one standard cubic foot per minute of Nitrogen. Experts recommend that managers work backward from every application that uses nitrogen first, and then tally it together to determine the total need. Both PSA and membrane generator systems are capable of delivering high volumes of nitrogen at comparable costs of operation. It is important to note that some equipment may require higher purity gasses for certain tasks. All applications are unique and On Site Gas Systems can tailor a system to meet your needs. Some common applications and nitrogen purity levels are as follows:

  • Food Packaging – About 99.5% for the majority of applications.
  • Blanketing to Avert Hazardous Conditions – Anywhere from 95% to 97%.
  • Heat Treating Metals – Materials and the processes determine whether purity levels can be 97% or as high as 99.999% (10 parts per million of O2).
  • Blanketing Vegetable Oils (Edible) – Approximately 99.9%.
  • Printed Circuit Boards – “Lead-Free” selective solder in most cases requires 99.999% (10 parts per million of O2). Both wave solder and reflow can require purities between 99.9% and 99.99%.

Commercial Nitrogen Generator Maintenance

Fortunately, generator maintenance is a fairly straightforward process and staff can be trained to perform general maintenance. On Site Gas Systems also employs a team of experienced technicians who can assist with on-site maintenance as needed.
