Principle of Operation

Under the balance of adsorption, when any kind of adsorbent adsorbs the same gas, the higher the gas pressure, the greater the adsorption capacity is. Otherwise, the lower the pressure, the smaller the adsorption power

carbon molecular sieve shows difference in adsorbing oxygen and nitrogen. Carbon molecular sieve is a substance with a lot of micropores inside. The PSA principal is to achieve the separation goal of oxygen and nitrogen which based on the adsorption quantity difference in the carbon molecular sieve when the pressure is certain.

When the pressure rises, the carbon molecular sieve adsorbs the oxygen and produces the nitrogen gas. When the pressure decreases, the carbon molecular sieve starts to desorb the oxygen until the pressure equals to the ordinary pressure. At that time, the carbon molecular sieve desorbs the oxygen completely. The PSA nitrogen generator is usually equipped with adsorption towers. It controls the pneumatic valve by PLC, thus the two adsorption towers can produce the nitrogen gas alternatively. One tower adsorbs the oxygen and produces nitrogen gas, the other desorbs to regeneration to produces the required nitrogen.

Process Flow Brief Description

Technical Features
1). Full Automation
All systems are designed for un-attended operation and automatic Nitrogen demand adjustment.
2). Lower Space Requirement
The design and Instrument makes the plant size very compact,assembly on skids,prefabricated from factory.
3). Fast Start-up
Start-up time is only 5 minutes to get desired Nitrogen purity.So these units can be switched ON&OFF as per Nitrogen demand changes.
4). High Reliabiity
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 around 15-years i.e. whole life time of nitrogen plant.So no replacement costs.
6). Adjustable
By altering flow,you can deliver nitrogen with precisely the right purity.
