What Is a Nitrogen Generator Used For and Other Common Questions

At On Site Gas Systems, we get a lot of questions. Whether our customers are asking us, What does a nitrogen generator do? or How do you make nitrogen gas? we understand that our products can be a bit complicated. To make it simple to understand, here are the short answers to our most commonly asked questions in regards to nitrogen generators.

What Is a Nitrogen Generator Used For?

Nitrogen gas is used in a wide variety of industries, including everything from food packaging to mining, and all of these uses require a consistent supply of nitrogen gas. Many companies use nitrogen cylinders to get the gas they need; however, that is a huge hassle, is a never-ending expense, and can halt production if the delivery doesn’t go smoothly. So what is a nitrogen generator used for? It is used to create nitrogen gas on site so the supply is unlimited and on demand.

What Does a Nitrogen Generator Do?

Very similar to the first question, the answer to What does a nitrogen generator do is that it literally produces nitrogen gas on site at a wide array of facilities. We even have nitrogen generators that can be used in remote locations.

How Do You Produce Nitrogen Gas?/How Do You Make Nitrogen Gas?

These two questions are one in the same, so we will keep them together. In short, there are two ways to answer the question, How do you produce nitrogen gas? The first way is with a PSA nitrogen generator. In this method, the adsorption process is used to separate the nitrogen out of the ordinary air. The second way is with a membrane nitrogen generator. With this method of nitrogen production, the air is forced through hollow fibers that act as reverse filters. The oxygen, CO2, and water in the air are all small, so they will permeate through the fibers. However, the nitrogen molecules are larger, so they will be the only thing left behind.

What Is PSA Technology?

The final common question we receive is, What Is PSA Technology? Basically, PSA stands for Pressure Swing Adsorption, and as mentioned above, the adsorption process literally means separating the nitrogen molecules from the oxygen molecules in the air. It works by filling a sieve-lined vessel with compressed air. The lining adsorbs the small oxygen molecules while the nitrogen molecules continue on into the receiver.

If you have any other questions about nitrogen gas generation that are not answered here, please don’t hesitate to contact us. We are the experts in nitrogen gas generators and we would love to help.
