Fully Automated High Purity Nitrogen Purification System 0.5-0.65 Mpa



The principal flow diagrams:


Air source as raw material compressed into the air storage tank by air compressor and the oil, water, and dust will be attached to the container wall and flow to the tank bottom. So should open the drain valve regularly. The other part will be into the compressed air purification system.

Air purification system should be consisted of three different filters, a degreaser, and cooling dryer. By freezing moisture ejector and fractional filtration, the compressed air will be removed with liquid water, oil and dust. It can make the dew pointof compressed air to be 2-10 ℃, and the oil content dropped to 0.001ppm, dust filter to 0.01µm, it can ensure the inlet air of PSA nitrogen and drain oxygen. All of nitrogen at the pop of the tower will be transmitted to nitrogen storage tank by the pipe, and via the flow meter into using locations.



Technical characteristics:

  • Fully automated running, have the variable-frequency energy-saving function, stable purity and flow rate at the same time. (The paten number:201220408277.4)
  • The use of technical advanced measures to fill with molecular sieve, and avoid the phenomenon of high pressure airflow leading to molecular sieve pulverization, assure the molecular sieve life;
  • Quick start, online display various parameters, import analyzer on-line detection, reliable quality, no worries;
  • Multifunctional integrated alarm(purity, pressure, ect.)
  • Touch screen dynamic display and storage; based on windows operating platform, which can realize pc operation;

I, Nitrogen generator system design


1.  Compressed air system

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.

Remark:We suggest air compressor prepare a spare set,to confirm the produce stable.


2Compressed air clarification system

Compressed air pass through 9 grade filters,then pass through cooling type dryer.let the compressed air cooling,let the vapour in the air condensation into water,along with dust,oil drain out the machine.It’s better to put the cooling dryer in the compressed room.

After the cooling dryer is the filters,there are two group filters,one is 7 grade main pipeline filters,another is 5 grade high quality oil removing filter.7 grade main pipeline filter precision is 1um,filter out 1um and larger solid state and liquid particle,vestigital oil content 1ppm w/w.5 grade high quality oil removing filter filtrate precision 0.01um,remove 0.01um and larger solid state and liquid particle, 99.9999+% oil,the rest oil content 0.001 ppm w/w. Compressed air quality can reach 1 class according to ISO8573.1. Such clean and dry compressed air can inlet active carbon filter,air buffer tank then inlet nitrogen generator part,after PSA device make out the nitrogen purity ≥99%.


3. Pressure Swing Adsorption Nitrogen making system

Pressure swing adsorption (PSA) is an advanced gas separate technique,it is widely used in gas supply field in the world.

3 .1  Adsorbing material

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..

3.2  PSA principal

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.



All systems are designed for unattended operation and automatic Nitrogen demand adjustment.
Low Electric Energy Consumption
All systems are designed for Energy-Efficient.
Lower Space Requirement and Short installation period
The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory. Tongyue Machinery has own TRUE brand of gas separation equipments.
Installation is very easy and convenient.
Fast Start-Up
Start-up time is about 30 minutes to get desired Nitrogen purity. So these units can be switched ON & OFF as per Nitrogen
Demand changes.
High Reliability
Very reliable for continuous and steady operation with constant Nitrogen purity. Plant availability time is better than 98% always.
Molecular Sieves Life
Expected Molecular sieves life is more than 10-years i. e. Whole life time of Nitrogen plant. So no replacement costs.
Simple operation and maintenance
All systems are designed by integrated solution for easy-operation and easy-maintenance.
