The Role of Nitrogen Generators in Oil Well Pressurization

Only 12% to 15% of the original oil well can be obtained during the oil extraction process. This is due to the drive pressure produced by the oil well, which makes extraction difficult. Oil companies have adopted a number of practices, including fracturing, gas lift, and stimulation, to try and obtain the rest of this available oil. However, these methods are met with varying levels of success and face criticism regarding their environmental impacts. In addition, 60% to 70% of oil usually remains in the well even after these processes.
Nitrogen generators can assist in oil well pressurization and other extraction processes to obtain the maximum amount of oil possible. This tertiary recovery technique can aid in increasing oil reservoir pressure, thus promoting the additional recovery of hard-to-extract oil.

Nitrogen Generators and Oil Extraction

Nitrogen is a common gas that is ideal for re-pressurizing oil wells due to its inert, oxygen-free properties. Nitrogen, unlike other gases, does not have a corrosive effect on borehole piping and can be used in fresh and saltwater injection environments. Nitrogen application can also be used on underbalanced drilling rigs to displace oxygen and combat the oxidation process.
Nitrogen generators are typically used in older reservoirs. The rate of production is usually no longer economically viable in these reservoirs, and the generator can help displace what is left of recoverable oil for extraction.
Nitrogen is inserted into multiple wells on the oil site during the extraction process. The remaining oil left in these wells is then forced into a larger production well for workers to remove the product. Nitrogen generators can improve oil extraction in these older wells by 200% to 300%!

How Nitrogen Generators Improve the Jewelry Making Process

Jewelry manufacturers practice soldering in nearly every aspect of their craft, from forming bases for their pieces to adding delicate, gorgeous detail for the final product. However, this process can be hindered by the presence of oxygen in the environment, leading to damage and corrosion of the metal involved. To reduce this risk, many jewelers are including nitrogen generators in their manufacturing process to create a barrier between the metal and the environment.

What Is Soldering?

Soldering is fusing two metals together with the application of heat. This heat source usually comes from a blow torch or other industrial device. During the soldering process, the manufacturer melts the metal objects and joins them together. A filler metal with a relatively low melting point fills the joint where the objects meet, forming a permanent connection when the metal cools.
Soldering is a delicate and dangerous process. However, it is an essential component in a wide variety of industries: welding, plumbing, electronics, and jewelry manufacturing. Jewelers especially use this process in their craft to form their artwork. Unlike soldering pipes, the soldering process in jewelry making requires a light touch for this intricate artwork, as the jewelers have to work with very delicate materials.
A major risk in the jewelry soldering process is the presence of oxygen in the environment. When soldering is done in an oxygen-rich environment, the metals can corrode and the bonds become less effective. As a result, the jewelry can fall apart.

Nitrogen Generation and Jewelry Manufacturing

A simple solution to reducing the risk of oxygen corrosion in jewelry manufacturing is to displace the oxygen-rich air using nitrogen. During this process, jewelry makers can use a nitrogen generator, such as those supplied by On Site Gas, to store the gas for use during the soldering process. These nitrogen generators separate nitrogen from other elements in the air, storing the gas in tanks for later use.
Simply put, nitrogen displaces oxygen in the air. When it’s time to solder material, the jeweler flushes the environment with nitrogen gas. This creates a barrier between the metal and the oxygen in the air, reducing the effect of oxidation. Since nitrogen is non-combustible, working with high-heat materials during the soldering process is completely safe.

On Site Gas Solutions

On Site Gas offers a variety of on site nitrogen generators to benefit jewelry manufacturers during the soldering process. These machines are designed for fine selective soldering applications that offer the most benefit to the jewelry-making process.

What Using Nitrogen Generators Means in Semiconductor Manufacturing – The Trend That Our Smartphones Demand

When you get right down to it, almost all electronic devices we use on a day-to-day basis contain semiconductors of some kind, and nitrogen is a key component in producing them. Gases have been imperative to the electronics industry since the middle of the last century, when the earliest examples of commercial transistors and circuits began being produced on a large scale. Today, several factors are driving up the consumption of gases, but the most notable is the sheer scale of deployment of semiconductor fabrication plants to meet the demands of large economies.
Gases are a desirable element in the world of tech for many reasons – they are easy to store, easy to produce on site and simple to deliver high quality nitrogen throughout the facility to multiple points of use with simple inexpensive piping. Additionally, it is easy to control gases’ chemical reactions at the molecular level. Therefore, nitrogen systems have become popular options for semiconductor manufacturing. Here are a few examples of nitrogen systems used in popular methods of semiconductor manufacturing:

  • Nitrogen Membrane Generator. This is a convenient, turnkey system. It arrives at your location, built to your specs and ready for you to put online.
  • PSA Nitrogen Generator. These systems effectively generate nitrogen by separating it from the oxygen in the air around you.
  • Nitrogen Cylinder Filling. Filling your own nitrogen cylinders is a cost-effective way to replenish your nitrogen supply. It beats the price of bottled gas.

So, what has increased the demand for these types of semiconductor manufacturing? Quite simply, the answer is gadgets. Semiconductor manufacturers are staring down the barrel at an intense challenge, the intersection of ever-increasing demand and the need to continually lower costs. Not only are the devices we all have in our pockets more complex than ever, but there is an ever-growing trend to pack more into less. Laptops are paper-thin, and our smartphones hold a world of information in a package that can slip into the back pocket of fitted jeans. Can semiconductor manufacturing keep up? If so, nitrogen generators are a large part of the equation.
To meet the demands of a society that is increasingly dependent upon smartphones, semiconductor manufacturers have been using nitrogen inertion. Whether in the fabrication of stacked dies, rework, or component solder bumping, nitrogen gas allows a larger process window in the safety of minimal oxygen. As mandated, lead-free soldering has emerged; the combination of flux chemistry aggressiveness and the smaller Delta T temperature window has allowed N2 inerting to boost production success. Controlled nitrogen atmospheres in reflow, wave, selective, and rework applications give engineers a larger process arena to work in. Nitrogen also helps during the liquidous state while the solder is completing surface wetting for a good bond.
As we rely more on smartphones, the demand will continue to increase for this form of manufacturing. At On Site Gas, we strive to supply on-site nitrogen with the utmost safety and forward-thinking innovation to stay at the forefront of a rapidly digitizing world. If you’re interested in how on-site nitrogen can be used for semiconductor manufacturing, contact us today to learn more.

How Nitrogen Generators Improve Wine-Making

Wine-making is a delicate and sophisticated process that requires a skilled hand and deep knowledge of the science behind it. When wine is aging, it is crucial that the wine is protected from any contact with oxygen – if oxygen happens to seep into the cask or barrel, yeast and aerobic bacteria can grow. Oxidation can spoil the wine and drastically change its color, taste, and aroma, ruining years of hard labor.
A solution to wine-making’s oxygen issue comes in the form of another common atmospheric gas: nitrogen. By using a nitrogen generator, like the ones supplied by On Site Gas, winemakers can reduce oxygen levels in the environment to preserve the wine’s integrity.

How Do Nitrogen Generators Work?

On Site Gas offers multiple nitrogen generator options, including PSA Nitrogen Generator Systems, Membrane Generators, Container Systems, and Cylinder Filling Systems. For wine-making, On Site Gas recommends the use of a PSA Nitrogen Generator System.
PSA systems take the air we breathe and separate nitrogen molecules from oxygen molecules. This creates a flow of nitrogen gas that can be injected in multiple stages of the wine-making process.

How Does This Benefit the Wine?

Winemakers aim to create a nitrogen blanket across any surfaces where oxygen residue may lie, such as wine bottles, casks, and hoses. This creates a barrier between the wine and the oxygen molecules, reducing the risk of oxidation. Winemakers can use nitrogen generators in many steps while they’re storing, aging, and bottling wine.

  • During the bottling process, winemakers use nitrogen generators to flush wine bottles of oxygen before filling them. This prevents any oxygen residue from mixing with the wine and sparking the oxidation process before the bottle is opened.
  • After the wine has left the cask, winemakers flush the inside of the container with nitrogen to remove evaporated wine. This removes any oxygen residue before the next batch is made.
  • Sometimes, a winemaker will need to transfer wine from one cask to another container. Oxygen can easily mix with the exposed wine during this process. To combat this, winemakers’ flush tubes and vessels with nitrogen to remove oxygen residue before transferring the wine.

Nitrogen generators also assist with other wine-making processes such as fermentation, de-aeration, carbon dioxide adjustment, storage, and other production activities.

Additional Benefits of Nitrogen Generators

Nitrogen generators are a worthy investment for the serious winemaker. Nitrogen generators help winemakers produce the best quality product and ensure that each bottle leaves the vineyard without a risk of in-bottle oxidation.
In addition, nitrogen generators:

  • Are easy and simple to install
  • Require little maintenance and upkeep
  • Help winemakers wean themselves the use of argon, which is much more expensive than nitrogen
  • Reduce the need to sign large contracts with gas suppliers

On Site Nitrogen Generators for Chemical Blanketing

It is common for many industries (including Chemical and Refinery plants) to store their liquids and gases in storage tanks. However, it’s important to note that oxygen can degrade and oxidize, and if the stored substances (like flammable liquids) come into contact with oxygen this could create a potentially explosive and hazardous situation. This makes it essential for industries that store hazardous materials to implement a way to prevent a fire or explosion of their tanks. With nitrogen and chemical blanketing, you could provide ideal protection of your tanks, while at the same time, safeguarding the contents inside.

How Blanketing Works

Nitrogen and chemical blanketing (sometimes known as tank padding) is an ideal application for generated non-cryo nitrogen. It applies nitrogen gas to the vacant space in your storage container, and effectively reduces the actual oxygen in the vapor space. This process inactivates the oxygen, and at the same time, successfully eliminates the possibility of a fire or explosion of your tank.

Blanketing Methods and How to Best Protect Your Tanks

Producing your own nitrogen using an on site nitrogen generator is one of the most popular supply methods for nitrogen blanketing. However, when making your own on site nitrogen, you will need to determine how you will go about blanketing your storage tank in addition to what size of generator you will need.
When it comes time to decide how to blanket your storage tank, there are a few options to choose from. You can either use the continuous purge blanketing method, concentration control blanketing, or pressure control blanketing. With continuous purge blanketing being the most common technique, it is simple to set up, and you do not need a control device or control loop (but nitrogen consumption can be high). Concentration control blanketing does require a feedback loop to turn the generator on and off, but nitrogen use is also more efficient. If you use pressure control blanketing, a valve and pressure regulator controls your nitrogen levels.
The size of the generator that you need will depend on the amount of liquid lost during your pumping sessions and the condensation of your tank vapors that happen during atmospheric thermal cooling. Based on this information, On Site Gas Systems can help you determine what size generator is necessary.

Benefits of Nitrogen and Chemical Blanketing

Using a blanketing method stops a vacuum from developing in your tank, maintains consistent pressure, and reduces much of the evaporation of your stored material. This method also helps you save more of your materials, and at the same time, drastically reduces your emissions. Blanketing also has the potential to make your equipment last longer and you’ll never have to worry about refilling or replenishing because of the continuous production of nitrogen. On Site Gas Systems can assist you with attaining a custom nitrogen generation system solution for your business that will help you with all of your blanketing needs.

Using Oxygen Generators for Water Treatment Systems

Clean, pure water is a fundamental human necessity. Whether it be for cooking, or hygiene, every person needs safe water. Clean water is becoming harder to obtain as our worldwide consumption of water continues to grow. By injecting oxygen into your water system it can increase the effectivity of removing contaminants and impurities from your water supply.

How do Oxygen Generators Work?

Oxygen generators allow you to produce your own oxygen when and where you need it (versus relying on a liquid oxygen supply or depending on filled cylinders). By using Pressure Swing Adsorption (PSA) to generate oxygen, nitrogen is separated from the oxygen that is in the regular air.
At On Site Gas Systems, our oxygen generators have a vessel that absorbs the nitrogen molecules, and while the oxygen molecules drift past that vessel, they collect into an oxygen receiver tank. The oxygen receiver tank is attached to the oxygen generator, then releasing the pressure from the vessel and venting the nitrogen molecules back into the atmosphere. This cycle repeats in a second vessel, providing a consistent flow of gas from our oxygen generators.

What Applications are There for Oxygen Generators?

There are various applications for oxygen generators in water treatment systems including:
Oxygen Generators for Ozone: Using an oxygen generator for ozone is beneficial in many different situations. It works by acting as feed gas for your ozone system. It is environmentally safe, which makes it suitable for treating vast quantities of water efficiently (including ensuring clean drinking water from the tap). A couple of examples of using oxygen generators for ozone include making suitable drinking water for animals, water for cleaning equipment, and replacing chloride with ozone in swimming pools.
Oxygen Generators for Waste Water: Waste water can come from many different sources – whether it be from an industrial building, work office, or someone’s home, it can come from anywhere. By injecting oxygen into your waste water it can significantly increase bacteriological survival and regeneration. Oxygen generation systems can provide years of self-contained oxygen production – meaning you won’t have to deal with the ongoing expense of delivered cryogenically produced oxygen. Oxygen generators for waste water are also very cost effective and low in energy use. At On Site Gas Systems we offer custom engineered oxygen generators, oxygen container systems (up to 99% purity), and oxygen generators (up to 95% purity).
At On Site Gas Systems, we are experts in oxygen generators. Whether you’re looking for one to help with waste water, or ozone, we have what you need for your water treatment systems. Our systems are designed to meet your specific purity, pressure, and flow requirement needs (and at a lower cost than delivered gas).

Nitrogen Generators for Effective Fruit Storage

Fresh fruit is enjoyed all year round; however, it cannot be grown all year round. That’s where controlled atmosphere storage (CA) comes in. By strategically controlling the atmosphere the fruit is stored in with the help of a nitrogen generator, fresh produce can continue to be sold all year round.

Why Nitrogen for Fruit Storage?

Oxygen is fresh fruit’s enemy. When exposed to oxygen, produce begins to grow bacteria, including mold and mildew, making it spoiled and unsellable. By using nitrogen to inert the oxygen, just-picked fruit can be successfully stored without any spoilage in sight. Through this controlled atmosphere storage, fresh produce can be sold all year long, and the consumers will not be able to tell that the fruit was, in fact, picked months ago. And since the process doesn’t involve any chemicals, there is no impact on the quality of the fruit.

Best Nitrogen Generators for Fruit Storage

On Site Gas Systems has nitrogen generators that were specially designed for controlled atmosphere storage. They feature a proprietary flow control valve and nitrogen purity that allows precise control of the oxygen levels in the air. When it comes to nitrogen for fruit storage, there are two types of nitrogen generators that are recommended. These include:

  • Nitrogen Membrane Generator – This type of generator is ideal for high flow applications that require a lower purity. The generators are simple to operate and use a filter-like system to remove the oxygen from the air. They require minimal maintenance, have a quiet operation, and they can be custom built to meet the needs of the fruit storage facility. They arrive to the location ready to use.
  • PSA Nitrogen Generator – When a higher purity level is required, a PSA nitrogen generator is preferred. They work by running oxygen through a carbon sieve, which absorbs any oxygen or other gasses that are in the air, leaving only the nitrogen behind. PSA generators offer a quick ROI and provide reliable year-to-year costs.

The nitrogen generator you choose for your fruit storage facility depends on your specific needs. Regardless, you will reap the benefits of not having to worry about nitrogen cylinder delivery and storage, and you can dramatically decrease your recurring nitrogen gas costs. At On Site Gas Systems, we are experts in nitrogen generators. We can help you select the nitrogen generator that will produce nitrogen at the rate and purity you need for successful fruit storage.

How Oxygen Is Used in Glassblowing

Glassblowing is a unique art that combines the skill of melting glass with the subtle blowing of air to form masterful decorations. However, in order to work properly, the flame that the glassblower uses must be a specific temperature. That’s where oxygen gas comes in. With the high purity of oxygen gas provided by our 95% O2 PSA on site oxygen generators, glassblowers can make sure their torches remain the proper temperature for their masterpiece.

How They Use It

As mentioned, glassblowers rely on oxygen as their fuel for the burners and torches they use to melt the glass. Basic compressed air just doesn’t produce the necessary heat. Oxygen is the only fuel source that will ensure the flame is hot enough to effectively and strategically melt quartz and borosilicate glass. In most situations, the glassblower will use oxygen gas at a range of 10-15 psi, with a purity of 95%.

Why Glassblowers Rely on Oxygen Generators

Instead of having to manage and maintain oxygen cylinders, many artists are choosing to implement the use of an on site oxygen generator. This is for many reasons:

  • It Is Dependable – Not all glassblowers work in urban areas, and getting cylinders delivered is not reliable. With on site oxygen generation, there is no risk of running out of gas, so operations won’t have to come to a halt.
  • It Is Affordable – Oxygen cylinders can get expensive, and they are a recurring cost that doesn’t go away. On the contrary, with on site oxygen generation, glassblowers only have the upfront costs to worry about. Once those have been recouped, the artist can continue producing oxygen for essentially no additional costs.
  • Is It Safe – The art of glassblowing is dangerous enough, the last thing a glassblower needs to worry about is a high-pressure cylinder exploding and damaging something in the shop.
  • It Is Durable – Our on site oxygen generators are made to handle the most rugged environments, so wherever the glassblowing is being performed, the oxygen generator will stand the test of time.

Glassblowing is a meticulous art, and every detail matters. With the use of on site oxygen gas generator, a glassblower can be sure that the flame they are using stays at a high enough temperature to get them the results they need. The last thing they want to do is start all over because the flame isn’t hot enough. If you are in the glassblowing industry and you want to learn more about the true ROI of an on site oxygen generator, please contact us today. We would love to discuss the options available to you.

On Site Oxygen Use in Vet Clinics

With National Dog Day right around the corner (August 26th), there is no better time than now to discuss why veterinarians need an onsite oxygen generation system. A 95% pure oxygen gas is used on animals both during and after any type of surgical procedure. It helps to keep the animal stable until they can effectively breathe for themselves. In a typical situation, the on site oxygen generator is installed outside of the vet clinic or hospital, with feed lines going in to each of the operating rooms, so it does not take up the minimal space in most surgery rooms. On site oxygen generation can be used effectively for both large and small veterinary clinics.

Why On Site Oxygen for Vets

Just like other medical facilities, veterinarians need to be able to rely on their oxygen supply. It is impossible to predict how much oxygen will be required, and if the supply runs out, the pets’ lives are at risk. As such, it is evident why many vet clinics make the switch from oxygen cylinders to on site oxygen generation.

  • By producing their own oxygen, the veterinarian never has to worry about running out.
  • It is way more convenient to simply set up the oxygen generator and forget about it than it is to monitor oxygen tank levels and arrange for pick-ups and deliveries.
  • Over time, on site oxygen generation is also much more cost effective, as it only has to be paid for upfront, and has minimal maintenance fees over time. There are no recurring charges to deal with, other than minimal routine maintenance costs.

On Site Oxygen Options for Vets

At On Site Gas Systems, we carry all types oxygen generators for any application. This includes:

  • Customized oxygen generation designed for the specific needs of the vet.
  • Filling stations that can be used at either 93%, 95%, or 99% purity, allowing the vet to fill their own cylinders as needed for a fraction of the cost.

No matter how much oxygen gas a veterinarian requires, they can depend on our on site oxygen generation to provide it. For over 25 years, On Site Gas Systems has been engineering custom and off-the-shelf oxygen generation solutions for veterinarians in both rural and urban areas. To learn more about how on site oxygen for vets can benefit you, contact us today, and always have the oxygen you need no matter what animal emergency comes your way.
