The technology of PSA Nitrogen Generators produces nitrogen with a high purity of up to 99,9999% with 1.0 ppm residual oxygen covering flow rates from a few Nm3/hr to over 10,000 Nm3/hr. Like Membrane systems, these PSA Nitrogen Generators are also designed as free-standing modular systems for easy integration into new or existing plant installations. This gives you that added versatility and choice around the system and positioning of said system to best benefit your operations.

PSA technology is advanced and based on the adsorption principle, which is as follows: nitrogen and oxygen molecules from the intake atmospheric air are separated by a carbon molecular sieve (CMS). The larger nitrogen molecules penetrate the system as they are not absorbed by the activated carbon of the CMS. The nitrogen is then passed to the downstream nitrogen buffer tank system tank where the high purity nitrogen is ready to use.

IATT PSA Nitrogen Generators can be equipped as standard with touch control panels, modular expansion options and low maintenance valve technology. This means they are not only incredibly effective but also easy to use and efficient, saving you time and money and boosting your operations substantially.

How PSA Nitrogen Generation Works

PSA Nitrogen Generation is carried out using the adsorptive properties of adsorptive media such as a Carbon Molecular Sieve (CMS) or Zeolite. Oxygen and other trace gasses are preferentially adsorbed onto the adsorptive media at varying portions, depending on the system pressure, while the nitrogen passes through due to its molecular structure being too large to penetrate the fine porosity of the adsorptive media.

The system uses two pressurized twin towers to contain the adsorptive media where the clean dry compressed air enters at the bottom of one of the towers. Oxygen and trace gases are adsorbed, and nitrogen passes through the adsorbent media bed into a buffer tank prior to the outlet, further filtration and then onwards via the pipework distribution system to the process. After a predetermined time, dependant on the purity of nitrogen, the tower switches to regenerative mode and flows the pressurised compressed air into the second tower (hence the term Pressure Swing) where the process starts again. The first tower then depressurises, and the adsorbed oxygen and other trace gases are released and exhausted into the atmosphere. What is Adsorption?

In a gas application such as nitrogen generation, adsorption is the accumulation of molecules of oxygen and other trace gases to form a thin film on the surface of a specifically selected solid such as carbon or Zeolite by intermolecular forces – the adsorption process is reversible which facilitates the constant use of the system to generate nitrogen on a commercially viable scale.

A number of PSA (Pressure Swing Adsorption) twin tower units can be piped or manifolded together into a larger unit to enable high flow capabilities.

How Do Desiccant Air Drying Technologies Work?

To simply explain the process of desiccant air drying; wet air passes through the desiccant medium which in turn absorbs the moisture. The desiccant medium has a fixed capacity when it comes to absorbing moisture before it must be dried out, or regenerated. To do this, the tower containing a saturated desiccant medium is depressurized and the accumulated water is driven off.

How this happens depends on the type of desiccant dryer, which we have touched on above. We’re happy to discuss this kind of query as well as anything else you might need to know about the products or services we provide, so please don’t hesitate to get in touch with our team of experts today.

The IATT Oxygen Industrial/medical Generatorsuse PSA (Pressure Swing Adsorption) technology to generate oxygen of purity up to 99.5% with flow rates of from 2,80 Nm³/h up to 240 Nm³/h and more.

The pressure swing adsorption process used to produce this highly pure oxygentakes place during a two-stage cycle that involves synchronized adsorption and desorption within two-generation towers.

What Is an Industrial Oxygen Generator and What Does it Do?

Industrial oxygen generators separate oxygen from compressed air using a special selective adsorptive technology, also known as PSA. There is a presence of oxygen within this compressed air of 21%, (with 79% nitrogen) which is allowed to flow through a zeolite molecular sieve. This maintains nitrogen which results in high purity oxygen at industrial and commercial gas production sites.

The PSA process detailed above is similar to that of a nitrogen generator, however, the adsorptive material inside the sieve isn’t made of carbon as is the case with nitrogen, but is instead comprised of zeolite. A unique aspect of zeolite and the reason it is ideal for oxygen generators is due to its ability to discharge retained nitrogen gas when the pressure within the generator is reduced. In essence, this makes it relatively simple to regenerate the medium for a further cycle of oxygen generation with an industrial oxygen generator.

The Various Applications for an Industrial Oxygen Generator

There are multiple functions and applications for PSA oxygen generators on industrial, medical, and commercial sites, including the following:

1. Papermaking
2. Metallurgy
3. Medical use
4. Glass manufacturing
5. Multiple foods and beverage industries
6. Chemical oxidation practices and processes
7. Commercial fish farming
8. Sewage plants and wastewater treatment plants
9. Various different forms of mining

  1. Gasification processes

And more. Get in touch to find out how IATT can supply and install Oxygen Industrial Oxygen Generators anywhere in the UK thanks to our tactically placed team of specialist installers and staff.

IATT AiroGen® Lab GasGenerators offer a module design and can also be stacked to meet compact storage requirements, this makes them perfect for usage within multiple generation applications. What is Adsorption?

To fully understand lab gas generators and swing adsorption technology, we must first explore what adsorption is. Adsorption refers to a gas application such as nitrogen generation and is the accumulation of molecules of oxygen and other trace gases.

This accumulation is used to form a thin film on the surface of a specifically selected solid, such as carbon, by intermolecular forces. The adsorption process involves a mass transfer and differs from absorption, where a specific fluid is dissolved by a liquid or solid. Adsorption is a reversible process and facilitates the constant use of the system to generate nitrogen on a sustainable scale for commercial use.

Nitrogen Generators and Nitrogen Generation Explained

Now, with the definition out of the way, let’s explore how nitrogen generators and the process of nitrogen generation work. PSA Nitrogen has generated the process of adsorption, where the adsorptive properties of specific media, such as a Carbon Molecular Sieve, are used. Oxygen and other trace gasses found through the process are consequently adsorbed onto the adsorptive media at varying portions, depending on the system pressure present. In turn, the nitrogen passes through the media because of the fact that its molecular structure is too large to infiltrate the fine permeability of the adsorptive media in question.

The system utilized within our lab gas nitrogen generators and the generation process, in general, is with two pressurised towers to contain the adsorptive media. Here, the clean dry compressed air enters at the bottom of one of the towers where oxygen, carbon dioxide, moisture, some hydrocarbons, and trace gases are adsorbed. The nitrogen then passes through the adsorbent media bed into a buffer tank, prior to the outlet where it is subject to additional filtration and pushed on for use in the analytic application. After a predetermined time which is dependent on the purity of nitrogen required, the tower switches to regenerative mode and streams the pressurized compressed air into the second tower.

This is where the term Pressure Swing originates and is put into action.

Then, the process begins again. The first tower finally depressurizes, and the adsorbed oxygen and other trace gases are distributed and expended into the atmosphere.
