Nitrogen for Renewable Energy

Wind power is one of the fastest-growing types of renewable energy sources. In fact, approximately seven percent of the United States’ electricity was produced by wind in 2018. That’s 275 billion kWh, according to the Energy Information Administration. And as wind energy grows, reliance on fossil fuels will decrease, which could reduce carbon dioxide emissions and have a positive impact on the environment.
In order to ensure that the wind turbines operate efficiently, nitrogen must be provided to the turbine actuator. Because of this, nitrogen generators can be extremely beneficial to companies in the renewable energy industry.

Ensuring Efficient Wind Turbine Operation with Nitrogen

Wind turbines work by turning wind power into electricity. This is accomplished via large blades that are attached to a tall base. The blades are also connected to a hydraulics system with an accumulator. As the wind moves the blades, it activates the hydraulic system and the accumulator, which begins the process of creating energy so it can be stored or immediately used.
The accumulator is essential for this operation and consists of two compartments – one filled with gas and the other filled with fluid. Due to the design of the actuator, an inert gas is required to keep the two compartments separate. If the fluid absorbs any of the gas, it can affect the operation of the wind turbine. This is where nitrogen comes in. A constant supply of nitrogen gas can help prevent the contents of the two actuator compartments from mixing in the event of a leak. Nitrogen is an ideal solution because it is completely inert, doesn’t absorb moisture, and won’t combust or create an environmental hazard.

Benefits of Nitrogen Generators for Renewable Energy Applications

For medium and large wind turbine energy applications, nitrogen generators are the ideal solution. This is because one or more nitrogen generators can be connected to the wind turbines to supply a constant flow of nitrogen. Through a system of sensors and pressure valves, the generator can supply the wind turbines with on-demand nitrogen, greatly reducing the chances that the gas and fluid sides of the actuator will mix.

High-Quality Nitrogen Generators for Your Renewable Energy Business

On Site Gas offers a variety of different nitrogen generators for renewable energy applications, including:

  • Pressure Swing Adsorption (PSA) Nitrogen Generators – PSA generators are a reliable way to produce nitrogen for renewable energy applications. These generators create nitrogen by extracting it from the atmospheric air. They work by using pressure swing adsorption to separate the oxygen and nitrogen molecules. The nitrogen can be stored in a tank or used immediately, depending on the generator’s configuration. These systems are known for their stable year-round nitrogen prices.
  • Membrane Nitrogen Generators – This type of generator uses a membrane to separate the oxygen from the nitrogen molecules. The oxygen is released back into the atmosphere while the nitrogen is stored. Membrane generators can produce nitrogen gas with purity levels up to 99% and require little maintenance.
  • Custom Engineered Systems – In some instances, your renewable energy operation may require a custom-built nitrogen generation system. At On Site Gas, we can produce completely customized nitrogen generators to meet specific needs. And once your custom nitrogen generator is built, it can typically be installed in as little as one day.

Nitrogen Generators for Adhesive Purge

Does your manufacturing process require you to bond two or more materials together with commercial or industrial adhesives? If so, you may notice that your adhesive bonds are not as secure as you’d like. This is often due to oxygen and moisture infiltration during the bonding process. Luckily, using high concentrations of nitrogen (N2) can help ensure strong bonds by displacing oxygen, moisture, and particles to ensure that you get a high-quality finished product.

How Oxygen Affects the Bonding Process

In order to securely bond two materials, there cannot be any contaminants between the items and the bonding agent. One of the ways contaminants can be introduced into the bond is through oxygen infiltration. Oxygen typically contains impurities in the form of moisture and particulate matter. When particles are present, the bonding agent loses some of its effectiveness. This can result in a weak or incomplete bond, which reduces the durability of the finished product.

Benefits of Nitrogen for Adhesive Purging

When it comes to creating consistently tight bonds, oxygen, moisture, and other particles must be removed from the area before and during the bonding process. This can be accomplished by using nitrogen. When this gas is incorporated into the bonding process, it displaces oxygen and moisture as well as other particles that can negatively impact the strength of the bond. Once all of the oxygen has been removed, a tighter bond can be formed between the two materials.

Nitrogen Generators for Adhesive Purge

N2 generators for adhesive purging are the most cost-effective way to ensure your business has reliable access to nitrogen. On-demand generators can remove oxygen from normal atmospheric air, leaving you with high purity levels of nitrogen gas. Plus, generators give you consistent access to nitrogen, meaning you won’t have to spend money on monthly cylinder orders or refills. On Site Gas offers several different types of N2 generators, including:

  • Pressure Swing Adsorption (PSA) Nitrogen Generators – PSA nitrogen generators are known for their consistent production of nitrogen and stable gas generation prices.
  • Nitrogen Membrane Generators – Nitrogen membrane generators are known for their low maintenance costs, extreme reliability, and longstanding durability. They can produce purity levels of up to 99 percent.
  • Engineered Nitrogen Generators – When a standard nitrogen generation system isn’t enough for your business, we can custom-design one to fit your needs. Once your unique system has been constructed, it can typically be installed in one day.
  • Used and Refurbished Nitrogen Generators – If you’re looking for an affordable way to generate nitrogen at your location, a refurbished system may be what you need. All of our used nitrogen generators are inspected and fully restored, which means you can enjoy consistent access to nitrogen at an affordable price.

Nitrogen Generators for Power Plants

Are you experiencing corrosion and leaks in your power plant’s boiler? If so, consider incorporating nitrogen into your processes. A nitrogen generator can help you maintain your boilers and prevent oxidization and rust when they are not in use. Here at On Site Gas Systems, we offer a variety of high-quality nitrogen generator systems for power plants.

Power Production, Boilers, and Corrosion

Whether you operate a coal, oil, or nuclear power plant, you probably have several boilers that are designed to produce steam for the generation of electricity. While this method is extremely efficient, it also comes with certain drawbacks.
When boilers aren’t in use, any leftover water and moisture can cause rusting, pitting, and corrosion within the pipes. This can lead to leaks and a loss of boiler efficiency. You may even notice that you have to make repairs and replace sections of pipes more frequently than you’d like. To eliminate moisture in your system, we recommend using nitrogen. With a low-pressure, slow flow nitrogen purge, you can displace oxygen in any wet parts of your equipment. In doing so, you’ll significantly reduce the chances of oxidation.

Benefits of Nitrogen Generators for Utility Plants

Many utility and power plants that use nitrogen choose to rent cylinders. And while this approach may appear to be most convenient, it may end up costing you more money and reducing your efficiency. This is because nitrogen cylinders tend to leak, sending usable nitrogen back into the atmospheric air and wasting your money. Additionally, cylinders must be ordered and delivered each month, which can interrupt your business operations if your supply runs low unexpectedly.
Generators, on the other hand, are a reliable and cost-efficient way to produce nitrogen at your location. These systems work by taking in atmospheric air, removing the oxygen, and storing the nitrogen for later use. This gives you access to a constant supply of pure nitrogen, which can save you money and time. With a nitrogen generator, there’s no need for costly nitrogen deliveries, and you’ll never risk running out!

Types of Nitrogen Generator Systems for Power Plants

On Site Gas offers several types of nitrogen generators for energy plants, including:

  • Pressure Swing Adsorption (PSA) Nitrogen Generators – PSA generators are extremely efficient and reliable when it comes to extracting nitrogen from the air and storing it. They can produce high purities of nitrogen, which means you can use them to blanket your boiler systems, remove moisture and oxygen, and prevent corrosion. They also offer stable yearly nitrogen gas costs.
  • Membrane Nitrogen Generators – Membrane nitrogen generators are completely turn-key and can produce up to 99.5 percent pure nitrogen. They do this by using a membrane to separate the oxygen from the nitrogen. Owners of membrane nitrogen systems enjoy low maintenance costs and reliable gas production.
  • Custom Nitrogen Generators – Some power plants require a specialized system for nitrogen generation. That’s why On Site Gas offers custom-designed nitrogen generators. These systems are built to your specifications so you can produce as much or as little nitrogen as you need. Once your new nitrogen generator is constructed, it can usually be installed in less than a day.

Nitrogen Generators for Breweries and Wineries

Does your brewery or winery still use delivered nitrogen cylinders for pressurizing and preserving your spirits? If so, you could be spending unnecessary money. At On Site Gas, we sell permanent and portable PSA and nitrogen membrane generators that can save you money and enhance your business operations.

Types of Nitrogen Generators for Breweries and Wineries

Nitrogen generators work by separating and removing oxygen from the air so only the nitrogen is left. The nitrogen is then stored in a tank to be used in the beer and winemaking process. There are several types of nitrogen generators available for use in wineries and breweries, including:

Benefits of Nitrogen Generators for Breweries

A generator can save you anywhere from 40 to 75 percent on your nitrogen costs and provide you with a reliable source that will never run out or leak. Beyond saving you money, nitrogen generators offer a myriad of benefits for breweries. These are just some of the ways a generator can improve your operations:

  • Can be used in conjunction with carbon dioxide
  • Helps pressurize kegs
  • Helps prevent spoilage
  • Can purge tanks between batches
  • Creates a more consistent product
  • Improves color, flavor, and carbonization

Benefits of Nitrogen Generators for Wineries

Nitrogen gas is used to displace oxygen during the winemaking process in order to preserve flavor and prevent spoilage due to contamination. Wineries typically use nitrogen for flushing, sparging, blanketing, and bottling. Flushing is needed during the transfer stages in order to purge pumps, hoses, and transfer containers. During the fermentation stage, nitrogen is added as tiny gas bubbles to remove oxygen – a method known as sparging. Blanketing is the process of pushing nitrogen through bottles, barrels, and tanks in order to remove oxygen prior to storing the wine.
It is estimated that wineries can save between 40 and 80 percent on nitrogen costs when they choose to install a generator versus renting cylinders. Not to mention, you’ll be improving your winery’s environmental friendliness.
Here are just a few more of the many benefits of nitrogen generators for wineries:

  • Improve your ROI and profit margin
  • Never run out of nitrogen
  • Prevent nitrogen leakage, which is common in cylinders
  • Reduce wasted wine due to spoilage

Nitrogen Generators for Laser Cutting

Nitrogen generators are extremely beneficial for manufacturing operations and businesses that offer precision laser cutting services. Using nitrogen during the laser cutting process can help reduce oxidation of metal surfaces and provide for a faster cleaner cut.

Laser Cutting with Nitrogen Generators

Using nitrogen during your laser cutting process can help you achieve precise, optimal cuts on metal, glass, and ceramic as well as other types of materials. Nitrogen keeps oxygen away from the cut, which prevents discoloration, scorching, and burning. Additionally, materials that are laser-cut with nitrogen are more likely to pass the bend test after welding and have a lower risk of paint adhesion failure.

Benefits of Using a Nitrogen Generator for Laser Cutting

Nitrogen isn’t flammable and doesn’t interact with the laser beam or the cut surface, which makes it ideal for use with laser cutters as well as welding machines.
These are just a few of the benefits of using a nitrogen generator during the laser cutting process:

  • Displaces oxygen around the cut to reduce the risk of burning, scorching, and oxidation
  • Removes molten metal from the path of the cut
  • Reduces laser cutting costs and improves ROI when compared to renting nitrogen cylinders
  • Allows for precise control of nitrogen purity levels
  • Reduces nitrogen waste
  • Provides access to a constant supply of nitrogen

Best Types of Nitrogen Generators for Laser Cutting

There are several different nitrogen generators that can be used for laser cutting. The type of machine you choose will depend on your current needs. Some of the best types of nitrogen generators for laser cutting operations include:

  • Nitrogen Filling Stations – If you already rent nitrogen cylinders or frequently need to take nitrogen to off-site locations, a nitrogen filling station may be the best solution. With this type of generator, you will be able to fill your own cylinders and transport them to various locations.
  • Nitrogen Membrane Generators – Because they have no moving parts, nitrogen membrane generators offer easy installation and low maintenance costs. In order to produce nitrogen, oxygen and moisture are separated from the atmospheric air via the membrane. We can custom build these systems to fit your desired specifications.
  • PSA Nitrogen Generators – These machines offer nitrogen purities of up to 99.999 percent. They use Pressure Swing Adsorption (PSA) to separate nitrogen from the normal atmospheric air. The nitrogen is then collected in a receiver while the oxygen is released into the atmosphere. PSA nitrogen generators are extremely efficient and cost-effective.
  • Engineered Nitrogen Generators – This type of generator is custom designed for laser cutting businesses. We take into consideration the volume of nitrogen currently used, future demands, optimal purity levels, on-site laser cutting equipment, and the types of materials your company cuts in order to custom design the perfect generator for your business.

What Is the ROI of an On-Site Nitrogen Generator?

Whether you package food, manufacture electronics, or brew beer (along with a slew of other industries), you use nitrogen on a daily basis. And if you are like most companies who rely on nitrogen for their daily operations, you have probably contemplated what the ROI for a nitrogen generator is. You currently rely on nitrogen delivery and are done with the recurring costs and hassles they bring, but you aren’t sure if the nitrogen generator system ROI is worth it. To assure you that it is, here is a closer look at a realistic nitrogen generator ROI.

Factors to Include when Calculating an On Site Nitrogen Generator ROI

Before you can begin to do the actual calculations of what a nitrogen generator ROI really is, you have to make sure you understand all of the factors at play. Some of the things to consider include:

  • How much you currently pay for nitrogen delivery, including the cylinders themselves along with the rental and delivery fees. And remember, this is a recurring charge that will never go away if you keep using this method of obtaining nitrogen.
  • How much nitrogen gas is being wasted by using these nitrogen cylinders. Approximately 10% of the gas never gets used in a cylinder.
  • How much you are paying for employee accidents due to them working with the liquid nitrogen that is a harmful -320 degrees Fahrenheit.
  • How much time is wasted dealing with the logistics of the delivery and pick-up of nitrogen cylinders. This is time that your employees could be working on something else.

Example of a Nitrogen Generator System ROI

Now that you understand all of the factors that go into computing the true ROI for a nitrogen generator, let’s break down some actual figures, assuming 6 days per week at 16 hours per day usage.

Annual Cost for Bulk Nitrogen

  • Assume that each month, you use 2,880 hundred cubic feet (CCF) of nitrogen gas.
  • If purchased at the average rate of $0.80 per CCF, this amount of bulk nitrogen would cost you $2,300 per month.
  • This equates to an annual bulk nitrogen gas cost of $27,650, plus any delivery charges or rental tank fees.

Annual Cost for an On Site Nitrogen Generator

  • Assuming the same usage needs in the example above, you purchase a nitrogen generator that produces 683 SCFH.
  • You pay an average of $0.10 per kwh to power the generator.
  • This puts the cost of the nitrogen gas down to $0.0614 per CFF.
  • To meet the same needs mentioned above, you would pay an annual cost of $2,120 to run the equipment. Add in about $550 for maintenance and filter changes, and your annual cost of a nitrogen generator is $2,670.

Using this example, you can expect to have a full nitrogen generator ROI within 17 months. After that time, you will continue to save over $25,000 per year. Of course, your operation needs may vary from this example, but the point is clear: While a nitrogen generator has a higher upfront cost, it will pay for itself time and time again.

How to Determine the Cost of a Nitrogen Generator

Are you considering purchasing a nitrogen generator and wondering how much they cost? These systems can cost anywhere from a few thousand dollars to more than $30,000, depending on the size of the generator and your specific needs.
Let’s take a look at how to determine the cost of a nitrogen generator.

How Much Nitrogen Do You Use?

Before you purchase a nitrogen generator, it’s important to determine how much you use on a daily, weekly, and monthly basis. If you’ve previously used nitrogen cylinders, an easy way to determine your average usage is by examining your past purchases. What was the volume of gas in those cylinders? How much did they cost to rent, and did you run out of nitrogen at any point?

What’s the Ideal Purity of Your Nitrogen?

Nitrogen generators have the ability to produce purities of up to 99.999 percent.. In addition to determining your purity level, you need to know the required flow and outlet pressure. These three variables will help to determine the cost of your equipment.

What Type of Nitrogen Generator Do You Need?

Nitrogen generators typically come in two forms – stationary and portable. Stationary nitrogen generators do not move; once they are installed, they must remain in place. Portable generators, on the other hand, can be moved using a trailer system. Your cost to purchase will depend on the type of system you need for your business.

How Nitrogen Generators Can Save You Money

For many businesses that require nitrogen, the go-to solution is to rent cylinders because it’s fast and reasonably reliable. However, these tanks usually never get emptied and you are wasting as much as 20 percent of the encased nitrogen. Cylinders must also be transported within your facility, which can lead to workplace accidents and an increase in workers compensation claims.
Unlike nitrogen cylinders, on-site nitrogen generators provide a constant supply of nitrogen directly on your property, you won’t have to worry about the risks associated with transportation. Therefore, while there is an initial investment to purchase a nitrogen generator , purchasing one could save you money in the long run.

How to Buy a PSA Nitrogen Generator

Here at On Site Gas, we offer new and used nitrogen generators. We have membrane nitrogen generators, portable generators, nitrogen filling stations, custom engineered systems, and Pressure Swing Adsorption (PSA) nitrogen generators for sale. If you know the type of system you’d prefer, you can order it directly from us at affordable prices. And if you’re not sure or you want to spec your system, we offer custom quotes.

10 Common Foods Packaged with Nitrogen Gas

Nitrogen gas is essential for the food packaging industry, as it increases the shelf life of packaged food products. The presence of oxygen in a package can lead to mold growth and spoiling before its use-by or expiration date. By removing the existing oxygen and replacing it with nitrogen, the food will remain fresh and safe to eat for a longer period of time.

Which Foods Are Packaged with Nitrogen Gas?

Modified atmosphere packaging is extremely common in the food industry. It is the process of removing the oxygen from a package and replacing it with nitrogen gas. A good rule of thumb is that if the food is packaged in an air-tight container, there’s a good chance the gas inside is nitrogen rather than normal atmospheric air.
The following foods are typically packaged with nitrogen gas:

  • Chips, Popcorn, Nuts, and Other Snack Foods
  • Fresh Meat
  • Prepackaged Lunch Meat
  • Salad Mixes and Bags of Lettuce
  • Pre-cut Apples and Carrot Sticks
  • Bacon, Smoked Sausage, and Kielbasa
  • Wine Bottles
  • Emergency Food Rations
  • Berries
  • Frozen Foods

Nitrogen Gas in Food Packaging

Nitrogen gas is used in food packaging because it preserves the color, flavor, and texture of the product while preventing spoilage and extending the shelf life. In the case of chips and snack foods, the nitrogen gas also provides padding that prevents the products inside from breaking into crumbs. If these same foods were to be packaged with air, they would quickly start to change color, grow mold, and spoil. Therefore, when you see a package of lunchmeat or a container of sliced apples with a broken seal, you should never purchase it. This is also why supermarket employees are required to remove and discard damaged packages.

Vacuum Packing with Nitrogen

Modified atmosphere packaging requires the use of a vacuum. During the packaging process, the food is placed into the container. Then, all of the oxygen is removed using the vacuum. The package is then filled with nitrogen and immediately sealed. This process is often used for items like chips, popcorn, pretzels, and lunchmeat.

Nitrogen Gas Generators for Food Packaging

Here at On Site Gas, we sell new and used nitrogen gas generators for use in the food industry. You can choose from PSA nitrogen generators, nitrogen membrane generators, nitrogen cylinder filling stations, and custom engineered systems. Our machines have the ability to produce up to 99.999 percent pure nitrogen, which is necessary for preserving moisture laden foods, like sliced and cut vegetables, as well as foods that are meant to sit at room temperature.
