CE , ISO approved high pressure high purity nitrogen generator
Air compressor supply the raw material air for the nitrogen
generator. The nitrogen making system need high quality,stable
pressure and enough air consumption.Air compressor should use the
reliable, maintenance easily,low noise,screw air compressor.
Pressure swing adsorption (PSA) is an advanced gas separate
technique,it is widely used in gas supply field in the world.
Adsorbing material is the center part of PSA nitrogen
generator,Normally use the the Carbon Molecular Sieve,it can adsorb
the oxygen,CO2,water in the air,but can’t adsorb the nitrogen..
Because O2 and N2 these two gas molecule have diffusion rate
difference on the molecule sieve surface,O2 smaller diameter can
diffuse faster,most of them inlet micropore of CMS,the large
diameter N2 diffuse slowly,less of them can inlet ,use this
adsorption difference come true O2 and N2 separate.
(1) Inlet air:The air compressor press the air into transporting
pipe,then use the compressed air clarification system to remove the
water,oil,dust and so on,reach to air buffer tank,then pass through
air buffer tank into two adsorption tower.
(2) Adsorption: When air inlet adsorption tower,during the pressure
function,O2 and CO2 be adsorbed quickly.Formed N2 near the outlet
(3) Air outlet :When the adsorption process working in the best
status(Adsorption N2:O2 is the smallest),open the outlet
valve,transport the N2 into N2 buffer tank.
(4) Average pressure:After finished exhaust,rest some N2 in the
tower,so let it into another tower adsorb again with new air.This
process is finished when the pressure of two tower is the same,so
called average pressure.
(5) Exhaust :After average pressure finished,need to releasing the
air which adsorb by CMS to be ready for next adsorption,the
programme will open the air releasing valve automatically,let the
pressure in the tower back to the original status,meanwhile release
the O2,CO2,so than the CMS can adsorb new air again.
(6) These two tower exchange work can got N2 purity 99.9 %
Please check below chart of CMS adsorb under different pressure of
O2 and N2 :
3. Fully intelligent, automated, easier to operate
Microcomputer control and (industrial computer system) touch screen
control are built in the machine. From the microcomputer touch
screen, we can understand the nitrogen generator as follows:
(1) Real-time working condition, total running time, working
process and opening and closing statement of the valve.
(2) When operating, just need to turn on and off the machine, set
the parameters and view the system fault information through the
It truly realizes the unattended duty, intelligent and automated
operation of the equipment. It can function as the real-time
monitoring equipment of the user’s control room. If required, we
can monitor distantly parameters such as the flow of finished
nitrogen, purity, pressure in the user’s DCS system.
