Features and Benefits of a Self-Generating Nitrogen Cylinder Filling Station

Before the ability to generate nitrogen on-site became available, companies had to purchase their nitrogen elsewhere, schedule a delivery and worry about running out of nitrogen before the delivery arrives. Today, we have the ability to generate nitrogen on-site. These on-site nitrogen generation systems have changed the way that many companies attain their nitrogen.

On-site Nitrogen Generator Systems Eliminate the Need for Bulk Deliveries

The nitrogen generators and nitrogen filling stations On Site Gas Systems offers eliminate the need for bulk purchases of nitrogen. In addition, all of our systems usually provide a return on investment within 18 months’ time. The nitrogen generator systems we offer are designed to last for decades.
Our nitrogen filling stations are used all over the world. As long as you have air and electricity, our nitrogen generator systems can operate; furthermore, the N2 generator systems we offer are compatible with worldwide power supplies.

On-site N2 Generation

Membrane Technology for Nitrogen Generation
The membranes used in our nitrogen membrane generators are bundles of hollow fibers. These fibers are porous and designed to allow oxygen molecules to pass through; however, the nitrogen molecules are too large and unable to exit. Air is forced down the fiber, which pushes the smaller oxygen molecules out of the pores, meanwhile the nitrogen molecules are captured at the opposite end.
The air that is being pushed through the membrane is usually heated: This heated air excites the oxygen molecules; thus, increasing the likelihood that they will permeate the holes in the membrane.
If you add a nitrogen filling station – your Nitrogen Generaror your staff will be able to fill their own nitrogen cylinders.

10 Features & Benefits of Nitrogen Cylinder Filling Stations

Why Generate Your Own Nitrogen or Oxygen Gas?

Nitrogen Generator BlogVarious industries, hospitals, and businesses may feel like they have no other option than to get cryogenic gas delivered in bulk to meet their nitrogen and oxygen needs. But this is not the case. On Site Gas makes it possible for these facilities to generate their own nitrogen and oxygen by means of an O2 & N2 Site self-generating system. When compared to cryogenic gas, these systems offer a variety of advantages.
Advantages of O2 & N2 Self-Generating Gas Systems

Ease of Use

No contracts to sign, you can purchase, lease or rent nitrogen and oxygen generating systems.

Low Maintenance Costs – System Can Last for Decades

Regular maintenance helps our nitrogen and oxygen generators last for decades.

Portable

Many of the O2 & N2 Site systems offer portability. These systems can be used anywhere that electricity and air are available. These systems are even usable in harsh conditions and extreme climates.

Less Expensive Than Purchasing Cryogenic Gas

The O2 & N2 Site gas generating systems are economical. The typical cost per CCF of the self-generated gas systems ranges from one-third to one-half of the costs associated with purchasing cryogenic gas.

No More Concerns About Running Out of Gas

Any concerns related to running out of gas are eliminated because the O2 & N2 Site system generates its own gas.

Pressure Swing Adsorption (PSA) and Membrane Technologies – How They Work

The O2 & N2 Site systems have two ways of generating gas: membrane technology or PSA.

The Process of Pressure Swing Adsorption

That is adsorption, not absorption. These two words may look similar, but they mean two very different things. Adsorption differs from absorption in that absorption is a chemical process, whereas adsorption refers to the physical process of actually separating gas molecules from one another.
PSA systems are designed to generate both N2 and O2. Compressed air is used to pressurize a vessel that is filled with zeolite or carbon. Zeolite and carbon separate molecules according to their structure or physical composition.
The forcing of air into the vessel causes either the O2 or N2 molecules to become trapped; meanwhile, the other gas floats free. As pressure releases, the O2 or N2 molecules are drawn off and collected in the tank. The captured molecules of unwanted gases are released into the air via a pressure release valve. These unwanted gases immediately recombine into ambient percentages.
Our systems consist of two sieve beds working at opposing ends of the cycle. This ensures there is constantly a consistent flow of O2 or N2.

The N2 Membrane – How it Works

The membranes in our systems consist of a series of hollow fibers that have holes in their walls. These holes are small enough to allow O2 molecules to escape. These molecules escape when pressure within the fibers increases.
These holes are too small to allow N2 molecules to escape. Therefore, when air is forced down the fiber, the O2 molecules exit the fibers and the N2 molecules are captured in the fibers at the opposite end.
The air within the membranes is typically heated. Heating the air excites the molecules, which increases the chance that they will exit through the holes in the fiber.

Our Nitrogen and Oxygen Generating Systems Are Durable and Versatile

Our nitrogen and oxygen generating systems are used across essentially every conceivable place where these gases are needed. We build our N2 and O2 generator systems under the assumption that they need to operate for decades.
That is why our nitrogen and oxygen generating systems are used even in the most remote places on the planet, at numerous combinations of hertz and voltage as well as under the most extreme climates. In fact, our portable oxygen generators are saving the lives of military personnel, no matter where they are located.

How It All Works: PSA and Membrane Technologies Made Easy

A variety of manufacturers utilize Nitrogen and Oxygen gas for numerous applications. The ability to generate gas on-site is more economical and efficient than gas delivery.
In order to achieve the proper nitrogen purity level, nitrogen generators rely on either membrane technology or pressure-swing adsorption (PSA); whereas, oxygen relies solely on pressure-swing adsorption technology.

Pressure-Swing Adsorption Vs. Membrane Technologies – What is the Difference?

Adsorption is a physical process where one substance fully integrates into another. Pressure-swing adsorption (PSA) technology is designed to use the concept of adsorption as a means to separate gas molecules from each other. The process of adsorption involves molecules temporarily adhering to the surface of certain materials they come into contact with.

PSA Nitrogen and Oxygen Generators – The Process

A pressure-swing adsorption nitrogen generator usually consists of at least two towers. These towers contain carbon molecular sieve. Carbon molecular sieve is adsorbent material.

PSA System for N2 Generation

When compressed air is forced into the towers, they become pressurized. Once pressurized, the O2 gas molecules become trapped within the carbon molecular sieve. As the pressure is released, the nitrogen molecules are collected in a tank; meanwhile, the oxygen is released back into the atmosphere via a vent. Once the unwanted gas molecules are released into the atmosphere, they rapidly convert back to their ambient conditions.
Companies that frequently use PSA systems for nitrogen generation include:

  • Plastic Molding
  • Packaging
  • Electronics
  • Food
  • Beverage
  • Metallurgy
  • Fruit Storage

PSA System for O2 Generation

O2 generators with pressure-swing adsorption technology works very similar to the N2 generator however zeolite is used to isolate O2 molecules; thus, separating them from the other molecules within the compressed air. Oxygen generating systems are perfect for use in wastewater treatment plants, for ozone production applications and fish farming; furthermore, the portable O2 generators available through On Site Gas Systems are ideal for use in the medical field.

Membrane Technology for N2 Generation

A nitrogen membrane generator is designed to remove nitrogen from the atmosphere. This is accomplished by pushing compressed air through a set of polymer fibers. As the compressed air moves through the membrane, the nitrogen molecules are separated from the other molecules. Tiny microscopic holes in the membrane fibers allow oxygen to pass through and return to the atmosphere as waste gas: The nitrogen molecules are too large to pass through the microscopic holes; therefore, the N2 molecules are captured at the opposite end.

Nitrogen Cylinder Filling Station

An N2 filling station is the perfect solution for manufacturers who purchase bottled nitrogen. A nitrogen fill station from On Site Gas Systems, allows for easy cylinder refills. With an on-site nitrogen filling station, concerns related to running out of nitrogen gas and/or waiting for a delivery are in the past.
On Site Gas Systems offers its clients systems of the highest quality. All the systems On Site Gas Systems offers are designed to operate for decades. These systems are reliable even in the most remote locations around the globe, under the harshest climates and in a variety of hertz and voltage combinations.

Nitrogen Membrane Generators for Mining in Africa

nitrogen membrane generator

Large amounts of nitrogen are essential to the nickel extraction process. Without nitrogen, the nickel mining process can be shut down with a loss of production.

How Nitrogen Gas is Used in Nickel Mining

When raw material is extracted from nickel mines, it travels “as is” to the processing facility. In the processing facility, nickel is separated from the raw material and captured for further processing. Nitrogen is a key part of this process; without large volumes of nitrogen, the nickel extraction process will inevitably come to a standstill.

Why On-Site Nitrogen is Crucial for Mining in Africa

The nickel mines in Africa are often in very desolate or remote locations, making it nearly impossible-or at least extremely expensive-for liquid nitrogen to be used. Not only that, but having to rely on liquid nitrogen deliveries can often leave mines without the supply they need to continue the nickel extraction process. If the mine is required to shut down because of a lack of nitrogen gas supply, it can result in over $1,000,000 per day of lost revenue, depending on the size of the mine.

On the contrary, with an on-site nitrogen membrane generator, the nickel mines in Africa are able to create their own consistent supply of nitrogen gas. They won’t be shut down because of bad weather or other delays of the delivery trucks. On-site nitrogen gas is the only way for mines to have a reliable, stable nitrogen gas supply to keep them operating at maximum efficiency.

Why Nitrogen Membrane Generators from On Site Gas Systems

We are known worldwide for our nitrogen membrane generators that provide mines with a dependable nitrogen gas supply. Our on-site nitrogen systems are available for long and short-term usage, as well as either for rental or for purchase. They can produce nitrogen gas at a purity up to 99.9% and a volume up to 6000 SCFM. There is no location too remote for our nitrogen membrane generators, and there is no application too complex. To experience the benefits of your own on-site nitrogen membrane generator, contact On Site Gas Systems today.

How NAPP Put a Nitrogen Generator to Work to Increase Their Productivity and Profitability

,

How NAPP Put a Nitrogen Generator to Work to Increase Their Productivity and ProfitabilityOftentimes, you don’t realize the value in something until you experience it for yourself. That is why we created our demo program, which allows companies to test out our nitrogen generators before fully investing in them.
Recently, Natural American Pet Products (which has since been acquired by Dogswell), a premier pet food packager in the United States, embarked on their path to nitrogen gas freedom by giving our nitrogen generator demo program a try.
Here’s their story…

NAPP’s Experience with a Nitrogen Generator

Natural American Pet Products (NAPP) was curious to test the ROI of an On Site Gas nitrogen generator at their pet food plant. Shortly after our first contact, we installed a nitrogen generator on-site at their Missouri facility. The rest is history.

  • Within 30 days of the demo nitrogen generator being delivered, NAPP purchased the unit outright.
  • Within 60 days of installing the nitrogen generator, NAPP sent back all of their nitrogen gas cylinders and LN2 dewars (and they don’t miss all the logistics that go along with them).
  • After five months, they had recouped all of the costs of the nitrogen generator.

Their Missouri facility now produces all of their nitrogen gas on-site using our nitrogen generator.

How a Nitrogen Generator Can Work for You

It’s easy to see why NAPP converted to solely using a nitrogen generator for their nitrogen gas needs. They were able to produce their own nitrogen gas when their production demanded it, and they didn’t have to deal with the deliveries and storage of nitrogen gas cylinders. This had a profound impact on their productivity.
Additionally, an on-site nitrogen generator allowed them to increase their profits drastically. Instead of the ongoing costs associated with nitrogen gas cylinders, they were able to pay for the nitrogen generator outright after five short months. Now, they have minimal overhead expenses for their nitrogen supply, and little-to-no maintenance to worry about.
If you are ready to see how a nitrogen generator can help your company flourish, contact On Site Gas Systems today. We would love to discuss our demo program with you to help your company become more efficient and profitable.

Benefits of On-site Nitrogen Generators in the Oil and Gas Industry

,

Nitrogen Generators in Oil and Gas Industry
Thanks to its odorless and non-reactive properties, nitrogen gas has many uses in the oil and gas industry. From moving materials through pipelines at refineries to re-pressurizing depleted oil wells and serving as a gas barrier to prevent explosions, on-site nitrogen generators can increase production and improve job-site safety.  Here are some of the many benefits to an on-site nitrogen generator:

Nitrogen Generators Reduce Downtime While Increasing Production

With on-site nitrogen generators, companies in the oil and gas industry are able to make their own nitrogen gas on-demand, which can eradicate unnecessary downtime and improve production rates. Additionally, an on-site nitrogen generator eliminates the need for constant nitrogen gas tank deliveries.

Nitrogen Generators Can be Easily Moved or Expanded

Another tremendous benefit of on-site nitrogen generators to the oil and gas industry is their capability to be easily moved from location to another (stationary nitrogen generators are also available, if preferred). The nitrogen generators are fully automated and simply require an electrical outlet to get started. Their maintenance is minimal and their operation is easy. Furthermore, nitrogen generators can be expanded and/or upgraded in the future, helping companies in the oil and gas industry grow as demand increases.

Nitrogen Generators Keep Worksites Safer

In the oil and gas industry, safety is always a concern. With on-site nitrogen generators, safety concerns can be greatly reduced in a variety of situations where an inert atmosphere is required.

How PSA Nitrogen Generators Work

Nitrogen mHow PSA Nitrogen Generators Workakes up 79% of the air we breathe, so there is an unlimited source right at your fingertips waiting to be tapped to save you 80% to 90% of your current annual nitrogen costs. A Pressure Swing Adsorption Nitrogen Generator simply separates the nitrogen molecules out of your compressed air stream to a usable purity, flow and pressure, based on your required specification. Unlike other nitrogen separation technologies, PSA nitrogen generators give you the ability to achieve extremely high purities to 99.9995% or 5 PPM. The PSA process is a physical process and uses no chemicals, therefore the annual consumables costs are extremely low. PSA nitrogen generators also put very little strain on the equipment and filter media so units often last 20+ years with very little maintenance costs. It is not uncommon for a PSA nitrogen generator to exceed 40,000 hours of service.

PSA Nitrogen Generator Purity Requirements and ROI

When developing your specification for a nitrogen generator, it is important to understand that the size and cost of the equipment is mainly based on the purity and flow rate required. With PSA generators, it is key to identify your maximum peak flow requirement at any given point during your operation. It is also important to identify the minimum purity that you require to maximize your savings potential. Most applications do not require the “one size fits all” purity supplied by your gas company. For example, many food-packaging applications require 99.5% purity. 99.5% is considered a low purity for PSA generation leading to extremely low cost equipment and very efficient compressed air to Nitrogen ratios. There are many applications where high purities of 99.999%+ offer tremendous savings as well.

Liquid Dewars Versus PSA Nitrogen Generators

Many of our electronics and lab customers are not candidates for bulk cryogenic tanks based on volume so they are forced to use expensive liquid nitrogen dewars. In most cases, liquid nitrogen dewars are roughly 50% more expensive than PSA generators. There are also many inherent dangers in using liquid dewars that just don’t exist when using a PSA generator. With a PSA nitrogen generator there are no deliveries, no rolling heavy wheeled pressurized canisters through the plant and no venting and boil off your product.
Please contact On Site Gas Systems to discuss your flow requirement, your purity requirement and your pressure requirement. We will then work with you to design a nitrogen generation system to maximize your savings potential. We will also provide you with a Return on Investment profile that will outline the “real” savings achieved using our Pressure Swing Adsorption technology.

Nitrogen Gas On Site in the Food Packaging Industry

,

Food Industry Nitrogen GeneratorsWith so much time spent on getting your product perfect, it only makes sense that you would want your food packaging to preserve its quality and freshness – all while keeping manufacturing costs low. Food is often damaged during shipment or has a shorter-than-necessary shelf life with traditional packaging. An easy solution to these common food packaging problems is a nitrogen generator from On Site Gas Systems.
Whether you use bags, cans, boxes, bottles, cardboard, or plastic, On Site Gas Systems offers a cost-effective nitrogen gas solution that gives you peace of mind knowing your product is fresh and intact on store shelves. Many companies are choosing to replace their current liquid nitrogen supply with On Site Gas Systems nitrogen generators to avoid ongoing energy and transportation costs associated with delivery of liquid nitrogen or cylinders. Beyond this, it’s important to understand these three reasons why On Site Gas nitrogen generators are a staple in the food industry:

Lengthens Shelf Life

Bacteria need oxygen to survive—it’s a matter of science. Without oxygen in your food packaging, you won’t have to worry about mold or mildew forming on your product. Our onsite nitrogen generator provides a simple, effective, affordable way to displace the oxygen out of your food packaging and replace it with nitrogen gas. As a result, your product can last a lot longer, so there is less waste.

Preserves Quality

Not only does nitrogen gas prevent mold and mildew growth, it also preserves the quality of your product. With nitrogen gas filling up the extra space in your food packaging, there is no room for moisture to get in—and as you know, moisture can deteriorate the quality of your food faster than just about anything. With a nitrogen generator from On Site Gas Systems, you can realistically save thousands of dollars per year because you won’t have to discard as much product.

Prevents Damage

Nitrogen gas for food packaging can prevent damage. If you place a fragile food product—like chips or crackers—in packaging that can be crushed during shipment, there is a high probability your product will arrive in pieces. On the contrary, with our nitrogen generator, you can easily fill the remaining space in your food packaging with nitrogen gas. In doing so, you will ensure that your product arrives to your customer as you intended.
For the past 28 years, On Site Gas Systems has been supplying reliable, USA-made nitrogen gas generators to food manufacturers across the world. From your morning coffee to an afternoon bag of chips (and even your glass of wine in the evening!), On Site Gas Systems help food packagers keep their product fresh and intact, while saving them time and money.
