Coal Storage Nitrogen Generation System / Mobile Nitrogen Gas Generator

Product Description:

1)The nitrogen generation system consists of the air compressor, the compressed air buffer tank, filters, refrigeration dryer, the PSA nitrogen generator, and the nitrogne buffer tank.

2)We always choose famouse brand air compressor, such as the Atlas Copco, the Ingersoll Rand to match the PSA nitrogen generators.

3)For filters, we choose Hankison, Domnick etc.

4)For refrigeration dryer, we choose J.mec etc.

For higher requirement of pressure and dew point, there may be some modification about for above components.

Equipment Advantages:

1) Quality First:

· Customized design based on customers' detailed requirement. The equipment is more suitable for the customers realy using situation.

· Adopting decent quality spare parts. We choose high quality valve and its service life reach up to one million times.

· Carry out the TQM management throught the whole manufacturing activities.

2)Highly Automation

· Automatically monitor and trace the working condition.

· The unit can automatically running, no need to be looked after by the worker.

3)Purity

· The purity of nitrogen can 95-99.99% ;

PSA Working Principle:

Air is composed of 78% Nitrogen and 21% Oxygen. PSA Nitrogen generation technology works on the principle of air separation by adsorbing Oxygen for getting Nitrogen.
Pressure Swing Adsorption (PSA Nitrogen) process comprises of 2 tanks filled with Carbon Molecular Sieves (CMS). (see image below).
Step 1: Adsorption
Pre filtered compressed air is passed through one CMS filled tank. Oxygen is adsorbed by the CMS and nitrogen comes out as the product gas. After some time of operation, the CMS inside this tank gets saturated with Oxygen and can no longer adsorb.
Step 2: Desorption
When the CMS is saturation in the one tank, the unit automatically switches nitrogen generation to the other tank. The waste gas (oxygen, carbon dioxide, etc.) is discharged into atmosphere.
Step 3: Renew
In order to regenerate the CMS in the tank, part of the Nitrogen produced by the other tank is purged into this tank. This makes quick CMS regeneration and make it available for produce nitrogen in the next cycle.
The above process cycle ensures continous supply of the Nitrogen.
