Product Description

1. Introduction of the PSA Nitrogen Generator
PSA (Pressure Swing Adsorption) is an advanced air separation technology. It remains an irreplaceable standing on site gas supply field.
Under adsorption balance condition, for any adsorbent, when adsorbs one sort of gas, the higher the air pressure is, the more quantity it can adsorb, vice versa. As show below:
As mentioned above, when the air pressure is high, the carbon molecular sieve will adsorbs lots of oxygen, carbon dioxide and water. When the pressure is reduced to the atmospheric pressure, the adsorbing capacity of the carbon molecular sieve to oxygen, carbon dioxide and water will be small.
The PSA equipment is composed of A and B two adsorption towers, which have installed the special carbon molecule sieve, and control system. When the cleaned compressed air enters tower A entrance and flows to the exit through the carbon molecular sieve (usually the pressure is 0.8MPa ), O2, CO2 and H2O were adsorbed by the carbon molecular sieve, while the nitrogen products flow out from the top of the adsorption tower. After a period of time, the carbon molecular sieve adsorption in tower A is saturated. This time, tower A will automatically stop adsorbing, the compressed air flows into tower B to carry out the oxygen adsorption and nitrogen production and then carry out the regeneration to the molecular sieve in tower A.
The so-called regeneration is the process of discharging the gas of the adsorption tower to atmosphere to make the pressure reduced to the atmospheric pressure quickly, and then make the oxygen, carbon dioxide, and H₂O adsorbed by the molecular sieve desorbed from the molecular sieve.
2. Features of PSA Adsorption Technology

The production purity is adjustable according to the change of flow;
Running under the low pressure and atmospheric pressure with safety and energy-saving;
Simple equipment structure, easy maintenance and low running cost;
PLC control, fully automatic unmanned operation.

7. Technical Process Explanation
Pressure swing adsorption (abbreviation is EETO), it is a physical process which is approximate the isothermal change, it uses the differences of the adsorption capacity to different components in gas medium, when the pressure increases, the adsorbent makes selective adsorption, when the pressure reduces, the adsorbent is desorbed and regenerates. EETO nitrogen generation usually adopts two adsorption towers, which is filled with the carbon molecular adsorbent, when one adsorbs oxygen and produces nitrogen, the other desorbs oxygen and makes regeneration. This alternate process constantly produces nitrogen.
Components of nitrogen generator are air compressor, compressed air cleaning assembly, air tank assembly, PSA oxygen and nitrogen separation assembly, nitrogen buffer tank assembly, and electric control system.
The compressed air flows into the buffer tank, goes through refrigerated dryer and three-stage filters to remove water, dust and oil, reduce the dew point of the compressed air to atmospheric dew point below -20ºC, and after the further oil removing by the active carbon, dry and clean compressed air can be obtained.
The clean compressed air flows into the air tank through the ball valve.
The compressed air coming out from the air tank passes by opening the throttle valve, with certain pressure and time interval, alternately enters into the adsorption tower A and B, oxygen with small diameter is preferential adsorbed by carbon molecular sieve, while nitrogen with large diameter flows through the top of the adsorption tower, and enters the nitrogen buffer tank for output through the pipeline pneumatic valve and the throttle valve. When one adsorption tower A or B is in the process of gas intake adsorption producing nitrogen, the other adsorption tower B or A is in the process of gas discharge desorption regenerating, the gas discharge desorption regenerating is that through opening the pneumatic butterfly valve, quickly discharging the oxygen-enriched gas adsorbed by the molecular sieve through muffler to the atmosphere, thereby making the carbon molecular sieve regenerate. The two adsorption towers adsorb and desorb alternately to produce nitrogen gas continuously. There is a shortly pressure equalization process between adsorption and regeneration, the so called pressure equalization is making the pressure of two adsorption towers equal through opening the pneumatic butterfly valve. The throttle valve is used to control the flow of the recycling nitrogen flushes the adsorption tower.
The nitrogen produced by adsorption tower is first storage in the nitrogen buffer tank, after removing the dust by the dust filter, adjust the pressure regulating valve to the set pressure, then adjust the throttle valve to the set flow to output, meanwhile, make a test of nitrogen purity and flow by the nitrogen gas analyzer, flow meter.
