Air contains 21% oxygen, 78% nitrogen, 0.9% argon and 0.1% other trace gases. PSA oxygen generator uses zeolite molecular sieve as adsorbent. Use two containers with zeolite molecular sieves (two towers, four towers or six towers) as adsorbents, using the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air, thereby separating the oxygen from the ...

The working principle of PSA oxygen generator： The normal air composition is: nitrogen (N2) accounts for about 78.1%, oxygen (O2) accounts for about 20.9%, and rare gases account for about 0.939% (helium He, neon Ne, argon Ar, krypton Kr, xenon Xe, radon Rn), Carbon dioxide (CO2) accounts for about 0.031%, and other gases and impurities account for about 0.03% PSA (Pressure Swing Absorption) oxyge...

This article makes a comprehensive analysis and evaluation for the design and safety use of the ultra-high pressure oxygen compression filling system, and proposes measures to prevent explosion accidents. Material combustion has three necessary conditions: combustible material, combustion-supporting material and combustion temperature (ignition source). Oxygen is one of the most common combustion-...
