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

Oxygen generator machines are valuable for businesses in a variety of industries. Oxygen gas is vital in many functions in supporting life and essential chemical reactions. Whether you are looking to replace your oxygen supplier soon or are in the market for buying an oxygen generator, it’s good to educate yourself on the many benefits an oxygen generator system can have in the business sector. Let’s take a look.

Benefits of Oxygen Generator Machines Explained

Oxygen has sustained human life on earth for countless millennia. The essential gas is also helpful in hospitals, welding facilities, aerospace, and many other industries. Today’s oxygen generator systems are safer at regulating oxygen production than other current means of oxygen supply. Their notable applications include fish farms, welding, research labs, veterinaries, and medical life support. On Site Gas manufactures high-quality oxygen generators to provide oxygen when you need it during those critical times.

In welding and metalworking, oxygen increases the temperature of the welder’s flame, making it useful in the precise cutting of steel and other metal alloys. While it takes skill to operate an oxygen-powered flame, its uses are advantageous and sometimes required for specific applications. It also melts the metal in a more localized area than other types of gas could.

In zoos and aquariums, oxygen plays a vital role in aquarium keeping and veterinary medical life support for many animals as the need arises. The oxygen supply is available quickly and efficiently minimizing any risk to the animals.

Many research facilities use oxygen generators daily in their line of work, including biochemists, universities, government science departments, and more. Depending on the research being conducted, a generator in this setting needs to operate dependably to preserve a safe working environment.

In the gold and silver mining industries, using oxygen to convert mineral sulfides to sulfates and processing them, gold yield can be more than doubled over standard or gravity separation and concentration. Oxygen is safer and produces a higher yield, effectively lowering the liability and increasing profits simultaneously. High-purity oxygen gas can be delivered directly to the worksite via a portable oxygen generator machine.

Last but not least, oxygen is best known for providing life support in various medical applications. Therefore, an oxygen generator machine needs to deliver the gas consistently and be dependable. It is a vital tool for hospitals, in-patient services, hospices, urgent care facilities, and ambulances. Portable generators are particularly useful in these situations.

The Role of Portable Oxygen in the Future of Mobile Clinic Medical Centers

In any disaster or emergency situation, it’s essential to have timely responses and adequate supplies of quality medical equipment. Proper preparation and access to machines like portable oxygen generators can mean the difference between life and death for those affected by a crisis.

Below, we’re discussing the pivotal role portable oxygen generators play in mobile medical clinics, as well as how these machines have been used throughout the COVID-19 pandemic.

COVID-19 Mobile Clinics

In response to the global COVID-19 pandemic, hospitals and clinics around the world – especially in locations that are most hard hit by the virus – are scrambling to come up with alternative solutions to treat as many people as possible. When the existing medical infrastructure doesn’t have enough beds and equipment, solutions like mobile clinics can be used to expand resources and increase the number of patients that can be treated. Mobile hospitals are also flexible and able to move to where they are most needed.

Many cities are setting up temporary shelters outside of hospitals to use as extra triage and treatment spaces. Additionally, some states are converting stadiums and convention centers into mobile medical clinics to accommodate for the large number of COVID-19 patients. Because the virus causes respiratory symptoms, oxygen is a crucial resource for treatment. Therefore, these temporary healthcare establishments require access to a reliable supply of oxygen at all times.

Emergency Oxygen Equipment for Mobile Clinics

The COVID-19 virus is known to cause severe coughing and breathing problems, requiring all medical facilities to have ventilators, oxygen masks, and oxygen tanks or generators on hand. Medical oxygen generators provide a continuous supply of oxygen to the patients who need it most. They are also easy to transport and can be used in virtually any location.

Some key features of portable oxygen generators include:

  • Reliability – Oxygen generators for field hospitals produce their own oxygen and have back-up power sources, so they can keep running without any additional equipment. This also allows them to operate during power outages or in remote locations.
  • Safety – When treating patients with oxygen, it’s essential to provide the safest gas possible. At On Site Gas, our portable oxygen generator systems (POGS) are medical-grade and FDA-approved for patient use. They produce oxygen at the proper saturation and pressure levels necessary for use in healthcare operations.

The Critical Need for Oxygen Generators During the COVID-19 Pandemic

Emergency medical oxygen generators are an absolute necessity during the current COVID-19 outbreak. Many patients require oxygen therapy due to the breathing issues that result from the virus, and healthcare systems across the country are being flooded with more patients than they are built to handle. Specialized equipment like oxygen generators for hospitals is critical for providing much-needed oxygen therapy in mobile clinics and other temporary medical establishments.

Oxygen generators can be quickly and easily moved into place and remain for as long as the disaster requires. Plus, they eliminate the need for oxygen cylinder deliveries, which are more expensive and may leave healthcare operations without oxygen if they run out before a new shipment arrives.

On Site Gas: Providing Life Saving Oxygen When It’s Needed Most

The future of the pandemic is uncertain, but On Site Gas is here to provide oxygen generators to help COVID-19 patients for as long as necessary. For more information about how our generators can provide critical oxygen for mobile medical clinics, contact us today.

On Site Gas Provides COVID-19 Medical Oxygen Generators for Samaritan's Purse

As the COVID-19 virus spreads across the globe, many cities are preparing for a drastic increase in individuals needing medical assistance. Many of our hospitals and clinics simply do not have enough beds, resources, and medical equipment to support the massive influx of patients. In response, many healthcare systems are establishing temporary facilities in hotels, stadiums, and other large buildings as well as field hospitals in outdoor tents. As more and more mobile clinics open, there is an increasing need for medical supplies and equipment.

Below, we’re discussing our involvement in the treatment of COVID-19 patients through our client, Samaritan’s Purse.

Emergency Field Hospitals in New York City

New York City has quickly become the epicenter of the COVID-19 crisis in the United States. To keep up with the influx of patients, the city is actively searching for new solutions to help alleviate the strain the virus has put on its hospitals. Over the past few weeks, they have established several mobile medical clinics, including:

  • The USNS Comfort, a Navy hospital ship, which is now docked in New York Harbor to care for extra patients that hospitals can’t accommodate.
  • The Javits Center, a large convention center, which has been converted into a large field hospital for more patient overflow.

An additional field hospital has also been constructed in Central Park to treat patients. It will serve as a respiratory care unit, dealing with COVID-19 exclusively. Samaritan’s Purse, a Christian humanitarian aid organization, was at the helm of the Central Park field hospital project, gathering volunteers and erecting tents along the East Meadow, near Mount Sinai Hospital. The group of tents houses 68 hospital beds, as well as an additional 10 beds that are equipped for ICU-level care. Samaritan’s Purse’s efforts have helped to relieve some of the strain on local hospitals, many of which are at capacity in terms of space and supplies.

On Site Gas Provides Oxygen Generators to Help COVID-19 Patients

Because the COVID-19 virus causes severe respiratory symptoms in some patients, oxygen has been a vital resource for treatment. Emergency medical oxygen generators, in particular, have proven invaluable, making it quick and easy to set up oxygen supplies in field hospitals and other temporary establishments. Instead of relying on oxygen tanks and cylinders, which are cumbersome to haul and need to be refilled or delivered regularly, medical oxygen generators can continually produce the gas with no waiting time..

6 Key Benefits of Oxygen Generators for Water Treatment

Despite water covering 70% of the earth, actual usable, fresh water is a scarce commodity. According to the World Wildlife Foundation, the fresh water necessary for human life only comprises 3% of the world’s water supply, two-thirds of which is inaccessible. In our everyday lives, we use water not only for consumption but for cleaning and irrigation as well.
The water left over from these processes is wastewater and needs treatment before it is safe to use again. Normally, to recycle our water for reuse, wastewater (used water containing pollutants) gets recycled at water treatment plants. Thankfully, now over-stressed water systems can get a break, thanks to the benefits of oxygen generators for water treatment facilities.

How Oxygen Generators Improve Wastewater Treatment

Wastewater takes an extremely long time to biodegrade. The biodegrading process occurs with the help of bacteria. Without oxygenation, the biodegrading process causes malodorous output and potentially harmful chemical reactions. With oxygen “feeding” the bacteria, the process significantly neutralizes the odors and negates the production of hydrogen sulfide and methane gas. Along with these two overall benefits to using oxygen generators to treat water, the following six additional benefits make the case in favor of water oxygenation self-evident:

  • Low Cost.The system of producing oxygen is self-contained, which means the unending bills for delivery of cryogenically produced oxygen are non-existent. These systems are cost-effective in terms of low-energy use, as well. The lower the energy requirement, the less you’ll be spending to run it.
  • Easy and Fast.This process is fast to implement and quick in practice, making the subsequent availability of freshwater more worth the effort in comparison to other methods.
  • Low Maintenance.One can accomplish maintenance on an oxygen generator system without technical expertise or complex training. Besides the basic upkeep and maintenance every machine needs, the requirement for repair is minimal.
  • No More High Wastewater Charges.Wastewater incurs its own charge, much like the use of clean water. The cost of treatment to sewage water drives up the bills of consumers. When the generator cost and the production of the generator are low, it drops the price of processing the wastewater.
  • Low Energy Output is Great for the Environment.Throughout the world, the quest to keep the use of traditional fossil fuels (gas, coal, etc.) to a minimum continues. The less energy needed to power the process, the less the negative effect on the environment.
  • The Purity Rating is Higher.Oxygen generators remove more pollution in water than traditional methods. Oxygen generators produce water at 95% purity while oxygen containment systems offer a 99% purity rate.

When one stacks the rewards of oxygenation of water against the drawbacks, the rewards far outweigh any potential cost. This clean, safe, easy, and low-cost method will contribute greatly toward solving current water scarcity problems, with lasting effects for the future.

Oxygen Generating System: Layout, Features & Benefits

On-Site-Gas-Blog-ImageFor almost 30 years, On Site Gas Systems has been providing industries with standard oxygen generating systems, as well as custom designed oxygen generators. We serve more than 70 countries and provide systems for dozens of industries. Our systems are reliable, which is why they are frequently utilized in mission-critical. The oxygen generators we offer our clients can be used virtually anywhere.

Standard Oxygen Generators

Every one of our systems is capable of lasting for decades, in even the most remote locations and harshest climates around the world; furthermore, our oxygen generating systems can be used globally because they are compatible with worldwide power supplies.

Custom-Made O2 Generators

Once the design process is complete, we build your customized oxygen generator to meet your exact needs. . Upon completion, you receive an unlimited supply of oxygen at your required flow, pressure and purity.

Pressure Swing Adsorption (PSA) in Oxygen Creation

The O2 generators that we create use Pressure Swing Adsorption as a means to generate oxygen. Adsorption refers to the process of physically separating gas molecules from one another.

Oxygen Generator System Layouts for 95 Percent and 99 Percent Purity

For 95 percent purity:
This oxygen system consists of a feed air compressor leading to a dryer, which leads to air storage, then to the two sieve beds and lastly, to an oxygen surge tank.
For 99 percent purity:
As with the 95 percent purity level system, there is a feed air compressor leading to a dryer, to air storage, to the two sieve beds and an oxygen surge tank; however, following the O2 surge tank is a 99 percent oxygen generator which leads to a 99 percent oxygen surge tank, then to a buffer tank and lastly, to a booster compressor.

Generating Oxygen Using the Pressure Swing Adsorption Process

Compressed air is used to pressurize a vessel that is filled with zeolite. The zeolite separates the molecules from one another. When the air is forced into the zeolite filled vessel, the oxygen molecules become trapped; however, the other molecules can float freely. As pressure is released, the trapped oxygen molecules are collected in the O2 surge tank for use; meanwhile, the unwanted gases are released back into the air via a pressure release valve. Once released, these molecules recombine with the ambient air. As the first sieve bed releases the nitrogen molecules, the second bed begins the process again. This ensures that you never run out of oxygen.

Benefits of Generating Your Own Oxygen

Prior to on-site oxygen generating systems, businesses, industries and hospitals had no choice but to purchase their oxygen elsewhere and have it delivered; however, all of the hassle associated with purchasing oxygen in bulk can be eliminated with an on-site oxygen generator. Our oxygen generators are a cost-effective choice: The average cost per CCF of self-generated oxygen is one-third to one-half less than the costs associated with purchasing cryogenic oxygen. With On Site Gas Systems, there are no delivery fees and our systems usually pay for themselves within an 18-month time frame.

Besides being economical, the oxygen generator systems from On Site Gas Systems offer:

  • Dependability – an On Site Gas Systems’ oxygen generating system uses the air that surrounds it to create the oxygen; therefore, our clients never have to worry about running out of oxygen.
