PSA Nitrogen Generator has 2-vessels filled with Carbon Molecular Sieves clean compressed air at 30º C temp. It passed through 1-vessel and Nitrogen comes out as product gas. The other vessel is depressurized to atmospheric pressure and purged with little quantity of Nitrogen coming out from other vessel. This regenerates Carbon Molecular Sieves for use in next cycle. Thus 2-vessels keep cycling alternately in Nitrogen production and Regeneration making Nitrogen gas available continuously. PSA Nitrogen Generator units are designed and supplied for 99.5% (Max) Nitrogen purity.
From PSA design Nitrogen pressure is available directly up to 5 Bar (A) without need of booster compressor. So this design is preferred for Low and medium pressure Nitrogen requirements.
PSA Nitrogen Generator is very simple in construction and very easy in maintenance and more popular for most Nitrogen requirements.
1. Full Automation
All systems are designed for un-attended operation and automatic Nitrogen demand adjustment.
2. Lower Space Requirement
The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory.
3. Fast Start-up
Start-up time is about 30 minutes to get desired Nitrogen purity. So these units can be switched ON & OFF as per Nitrogen demand changes.
4. High Reliability
It’s very reliable for continuous and steady operation with constant Nitrogen purity. Plant availability time is better than 99.51% always.
5. Carbon Molecular Sieves Life
Expected Carbon Molecular Sieves life is more than 10-years i.e. whole life time of Nitrogen plant. So no replacement costs.
6. Low investment and energy consumption
7. Simple operation and maintenance
