TY 500-99.9% PSA Nitrogen Generator whole system for chemcial industry usage
A. 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.
B. 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%.
1. 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.
2 .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..
2.2 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.
Normal purity N2 generator main parts.
