Working Principle
Main components of air are nitrogen and oxygen.Design appropriate technology process to separate nitrogen and oxygen with the use of different adsorptive property    (oxygen can be absorbed through nitrogen) of nitrogen and oxygen   on zeolite molecular sieve(ZMS) under ambient temperature,so as to acquire oxygen .The adsorptive capacity of oxygen on is stroner  than oxygen(the acting force between oxygen and the surface of molecular sieve is strong)  .When air passes through the adsorption bed with under the state of pressue,nitrogen is absorbed by molecular sieve.Oxygen is collected and flow out of the adsorption bed for little adsorption,and we can acqire oxygen through separation  of nitrogen and oxygen.When molecular sieve adsorption of nitrogen reach to saturation,and then stop entering the air and reducing pressure of the adsorption bed,the molecular sieve adsorption of nitrogen adsorption out of the molecular sieve regeneration and can be reused.This two adsorption bed rotation switch can continuously produce oxygen.
The boiling point of Oxygen and nitrogen are is very  close,soclose,so it's very  difficult to separate them,so the The PSA  Nitrogen  Equipment usually only get  a depth of 90-95% oxygen (oxygen limit concentration of 95.6%,the rest is argon),also known as oxygen-rich.the cryogenic air separation equipment can makemade more than 99.5% of the concentration of oxygen.
Equipment Process
The PSA oxygen Equipment must contain two steps:adsorption and desorption.For getting the continuous pure oxygen,usually device includes more than two adsorption beds,each adsorptin bed generally goes through adsorption,pressure relief,vacuum cacuumize,pressure reduce,pressre equalizing ,it takes periodic operation.
At the same time ,each adsorption bed works at the different steps,and it will automatically switch under the control of the PLC,two adsorp beds to coordinate cooperate to get the continuous oygen.
For the acutal  separation process,we must also consider the other trace components  in the air.The adsorption capacity of carbon dioxide and water on adsobbent are more than nitrogen and oxygen ,so it should  fill more suitable adsorbent in the adsorption bed (or use oxygen adsorbent itself) to  remove it out.
The number of adsorption tower of the oxygen plant  depends on the oxygen scale ; multiple-tower   operation will get better performance with  high investment,and the current trend is:the use of efficient oxygen adsorbent to minimize the number of adsoption towr and the short operatin cycle, to improve the efficiency of the devie to save invest.
Technical Features
Oxygen scale: electrical consume is lower if the oxygen capacity is lower than 10000m3/h,and the investment is small
Civil engineering is smaller,short installer period than cryogenic device;
lower   maintenance cost
automatic operation,convenience transport,less worker required
stability operation ,main parts are products of famous bland in the world
Use of imported oxygen zeolite,with superior performance and long life
Strong operational flexibility (with superior load and fast switch speed)
