PSA Nitrogen Gas Plant, Brand Name : JIABO, Certification : ISO9001

Psa technology utilizes two towers which are filled with carbon molecular sieve (cms). Compressed air enters the bottom of the "online" tower and flows up through the cms. Oxygen and other trace gases are preferentially adsorbed by the cms, allowing nitrogen to pass through. After a pre-set time the on-line tower automatically switches to the regenerative mode, venting contaminants from the cms. Carbon molecular sieve differs from ordinary activated carbons as it has a much narrower range of pore openings. This allows small molecules such as oxygen to penetrate the pores and separate from nitrogen molecules which are too large to enter the cms. The larger molecules by-pass the cms and emerge as nitrogen gas.
psa nitrogen generators are typically used in applications where the purity requirement is higher than 96%.
Advantages of psa nitrogen generator
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% always.
5. Molecular sieves life
expected 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
