The use of PSA technology in Nitrogen application

time2011/09/28

Currently, industrial nitrogen generator technology is very mature, PSA nitrogen generator technology has been in widespread industrial nitrogen.

PSA technology used to extract nitrogen from the air, in the small-scale users has been widely popular. PSA nitrogen at room temperature, the use of technology is the O2 and N2 adsorption on the adsorbent or the rate difference between different adsorption capacity, used in high pressure adsorption, desorption at low pressure to the preparation of the principle. Depending on the performance of the adsorbent, nitrogen is not the same mechanism. At present the use of carbon molecular sieve pressure swing adsorption nitrogen (CMS) and zeolite (MS) two technologies.

PSA nitrogen generator, compressed air through the dryer rigorous removal of raw water and CO2, and then into the MS molecular sieve bed, N2 adsorbed quickly on the bed, O2 and other impurities as adsorbed gas emptying, absorption through the end of the vacuum desorption, to be Products N2. Nitrogen on zeolite materials demanding, need to process more complex investment and operating costs.

Using this model of Nitrogen Nitrogen is also more mature now.
