Do you know this about on-site nitrogen generators?

With developing technologies and increasing awareness, many industrialists have already switched to on-site generators. Many wonder how these generators work and the benefits of using them.
 
So, in this blog, we will talk about the different technology available in nitrogen generators and the benefits of using on-site plants. 
 
Generating nitrogen on-site has three main advantages: eliminating wait time, delivering consistent purity, and lowering operational costs. And to produce nitrogen gas, there are 2 technologies available in on-site generators. These technologies are:
 

1. Pressure Swing Adsorption technology
2. Membrane technology 

 
PSA Nitrogen Generators
 

1. Ambient air is taken in through the intake valves and sent to Carbon Molecular Sieves (CMS). CMS has tiny pores that filter out oxygen molecules and other unwanted gases. These tiny pores are just the perfect size for oxygen molecules that get absorbed in them. Nitrogen gas has larger molecules. Therefore, it does not get absorbed in the material and pass on undeterred through the CMS. 
2. Over a period of time, the CMS would have absorbed too many molecules of oxygen while separating the gases effectively. Therefore, PSA nitrogen generators are designed with two chambers- one to separate the gases and purge high-purity nitrogen to eliminate the build-up of oxygen. Generally, these generators switch between the chambers every 60 seconds.

 
Membrane Nitrogen Generators

1. In this technology, dry, compressed air is filtered through hollow porous fibres where gas molecules and water precipitate into the air while nitrogen gas flows through the distribution system.
2. In this process, when the flow of nitrogen is increased, the gas incorporates more oxygen resulting in lower nitrogen purity. When the flow of nitrogen gas is decreased, the purity of the gas will increase. But different purity levels can be achieved by adopting a number of membrane bundles that can satisfy the application.

 
Whether it is a start-up or a well-established organization, investing in on-site generators is the best thing any industrialist can do.
