PSA Nitrogen Plant for On-Site Industrial Nitrogen Generation
Mar 24 , 2026Nitrogen is one of the most utilized gases in industry today. Thus, businesses must have an efficient way to produce it. Many companies have shifted away from bulk supply in favor of onsite generation. A PSA nitrogen plant is one of the most sought-after methods these days.
In addition to being convenient, PSA technology is versatile and less costly to operate. Industries need a constant supply of nitrogen, so they need dependable equipment. Nanjing Bangwin Gas develops nitrogen generation technology for customers worldwide.

PSA nitrogen plant is a device used to produce nitrogen gas on-site. The plant produces nitrogen by separating it out of compressed air. This occurs through adsorption process that traps molecules of oxygen and other impurities in carbon molecular sieve (CMS).
This leaves behind nitrogen as the product gas. Based on the design of the PSA system, it can produce nitrogen with up to 99.999% purity. Additionally, since PSA nitrogen plants run automatically, you can use them continuously for industrial purposes.
A PSA process consists of a series of adsorption and regeneration cycles.
l Compression of air:
Ambient air is drawn into the compressor. The compressor pressurizes the air so that separation can take place.
l Air purification:
Oil, moisture and particulates are removed by filters so that the adsorbent is not contaminated.
l Adsorption Phase:
The pressurized air is introduced to the adsorption towers. CMS adsorbs oxygen while allowing nitrogen to continue through.
l Delivery of Nitrogen:
Nitrogen is stored in a buffer tank which helps to regulate pressure and flow.
l Regeneration Phase:
The pressure in the tower is then decompressed. Oxygen is released from the adsorbent and exhausted from the system regenerating the adsorbent.
There are multiple towers that run in succession so that there is a continuous flow of nitrogen.
An overall PSA nitrogen plant is consisted of the following components:
l Air compressor
l Air dryer and filters
l Adsorption towers
l Carbon molecular sieve(CMS)
l Nitrogen buffer tank
l Control system
l Flow regulator and pressure regulator
We at Nanjing Bangwin Gas adopt integrated configuration which is easy for installation and has stable performance.
There are various kinds of configuration according to customer’s industrial requirement.
l Normal PSA Nitrogen Plant
