3. Process Flow Brief Description
According to the press swing adsorption theory,the high quality carbon molecular sieve as the adsorbent, under the certain pressure, carbon molecular sieve has different oxygen/nitrogen adsorption capacity,the oxygen is adsorbed largely by the carbon molecular sieve, and the oxygen and nitrogen is separated.
Since the adsorption capacity of the carbon molecular sieve will be changed according to different pressure, once lowering the pressure, the oxygen will be desorbed from the carbon molecular sieve. Thus, the carbon molecular sieve is regenerated and can be recyled.
We use two adsorption towers, one adsorb the oxygen to generate nitrogen, one desorb the oxygen to regenerate the carbon molecular sieve, cycle and alternation,on the basis of PLC automatic process system to control the pneumatic valve open and colse, thus to get the high quliaty oxygen continuously.
5. 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.
