One of the many advantages of producing your own nitrogen is that you can set the purity level to what your application requires. That is a
major difference to purchased nitrogen, which is always of the highest purity – even though most jobs don't need it. So what affects
nitrogen purity? And why does it matter?
The second question is easy to answer: High-purity nitrogen costs more because it consumes more energy. Therefore, you want to make sure
that you get the purity just right for your application. This is especially true because increasing it beyond what is necessary yields no
additional benefits.
In other words, using nitrogen with a purity of 99.99% for a job that calls for a purity of 99.5% wastes energy and money.
To answer the first question, we first have to look at how nitrogen gas is generated.
Types of nitrogen generators
Two
different technologies are used for the on-site production of nitrogen: pressure swing adsorption (PSA) and membrane. The key ingredient
in each case is compressed air, which contains 78% nitrogen. In the generator, that nitrogen is separated from the rest of the air.
In a PSA
generator,
this happens through adsorption. The generator consists of two separate pressure vessels. One of them is used to filter out the nitrogen
while the other is regenerating.
As the name indicates, a membrane
generator contains
a membrane filled with small, hollow polymer fibers. Not all gases, vapors and contaminants can pass through the membrane fiber wall with
the same ease. This allows the nitrogen gas to be separated from the compressed air. This is called “permeation.”
A PSA generator allows you to produce a nitrogen with a purity of up to 99.999%. It also requires less compressed air. However, the intake
air for the compressor has to be very clean and dry.
The purity a membrane generator can achieve is a bit lower. However, as noted above, most applications do not require the highest purity.
One of the benefits of this technology is that the intake air can contain water vapor.
Factors that impact your nitrogen purity
There are range of factors that could affect purity, some of which depend on the type of generator you use.
The amount of air that flows through the generator is the most important factor. If that intake air volume is too high, it will impact the
nitrogen purity because the pressure in the generator rises too fast. That means that the separating technology of the generator can no
longer keep up. As a rule of thumb, you want to keep you adsorption pressure between 0.6-0.8 Mpa.
An easy solution is to adjust the amount of air that comes from the compressor.
Another factor could be that the intake air contains too many contaminants. This could clog up the molecular sieve, which would have to be
replaced. To prevent this from happening, you can install air treatment equipment such as filters.
However, at some point, the performance of the molecular sieve will diminish, so you should always follow a maintenance schedule.
PSA generators feature a piece of equipment called a solenoid valve. Its failure is most frequently responsible for a decline in nitrogen
purity. When you notice that this purity drops, this is one of the first things you should check.
Where does nitrogen purity matter most?
The purity of your nitrogen is especially important when the nitrogen gas comes into contact with an end product. It matters less if you are
using it for fire suppression or inflating tires. On the other hand, the gas has to be very pure in the food industry or the pharmaceutical
sector. For these and other industrial applications, you need high purity nitrogen.
Many applications are subject to standards that will define the required purity. For example, there are specific requirements for food grade
nitrogen.

A common questions asked is why do I need an air dryer for my compressor? Typically, air compressors produce water, and although the
water can be drained, there can still be aerosol and vapour droplets that are present. This is because water cannoet be compressed. Water
can damage your compressor by corroding the valves, pipes and machinery controls, which will cost you time and money to resolve. In
the long run, the cost of a new compressor is a small price to pay compared to the loss of production that could potentially arise due
to water damage in your compressor.
Air compressors can fail for an assortment of different reasons: Normal wear and tear, lifespan and age of the unit, poor maintenance, power surge, install issues are just a few the come to mind. Check out this blog to find out our top 7 tips to ensure your compressor is looked
