Stable Performance PSA Nitrogen Generator For Chemical And New Material Industries

Stable Performance PSA Nitrogen Generator For Chemical And New Material Industries

PSA Nitrogen Generator Working Principles:

PSA Nitrogen Generator uses carbon molecular sieve as adsorbent, produces nitrogen by making use of the PSA principle. Under certain pressure, carbon molecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity. PLC controls pneumatic valve open/close to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces nitrogen with desired purity.

PSA Nitrogen Generator Applications:

1. Metallurgy: For anneal protection, agglomeration protection, nitrogenizing, furnace washing and blowing etc. Used in fields such as metal heating treatment, powder metallurgy, magnetic material, copper process, metallic mesh, galvanized wire, semiconductor, etc.

2. Chemical and new material industries: For chemical material gas, pipeline blowing, gas replacement, gas protection, product transport, etc. Used in fields such as chemical ,urethane elastic fiber, rubber, plastic, tyre, polyurethane, biological technology, intermediate, etc.

3. Electronic industry: For encapsulation, agglomeration, anneal, deoxidization, storage of electronic products. Used in fields such as peak welding, circumfluence welding, crystal, piezoelectricity, electronic porcelain, electronic copper tape, battery, electronic alloy material, etc.

Air is composed of 78% Nitrogen and 21% Oxygen. PSA Nitrogen generation technology works on

the principle of air separation by adsorbing Oxygen and separating Nitrogen.

Pressure Swing Adsorption (PSA Nitrogen) process comprises of 2 vessels filled with Carbon Molecular

Sieves (CMS). (see image below for detail of vessels).

Step 1: Adsorption
Prefiltered compressed air is passed through one CMS filled vessel. Oxygen is adsorbed by the CMS

and Nitrogen comes out as the product gas. After some time of operation, the CMS inside this vessel

gets saturated with Oxygen and can no longer adsorb.
Step 2: Desorption
Upon saturation of the CMS in the vessel, the process switches nitrogen generation to the other vessel,

while allowing the saturated bed start the process of desorption and regeneration. The waste gas

(oxygen, carbon dioxide, etc.) is discharged into atmosphere.
Step 3: Regeneration
In order to regenerate the CMS in the vessel, part of the Nitrogen produced by the other tower is

purged into this tower. This allows for quick regeneration of the CMS and to make it available for

production in the next cycle.
The cyclical nature of the process between the two vessels ensures continuous production of pure

Nitrogen.
