Carbon Steel N2 Nitrogen Generator
Carbon molecular sieve can adsorb oxygen and nitrogen in the air at the same time, and its adsorption capacity also increases with the increase of pressure, and there is no obvious difference in the equilibrium adsorption capacity of oxygen and nitrogen at the same pressure. Therefore, it is difficult to complete the effective separation of oxygen and nitrogen only by the change of pressure.
If the adsorption rate is further considered, the adsorption characteristics of oxygen and nitrogen can be effectively separated. The diameter of oxygen molecule is smaller than that of nitrogen molecule, so the diffusion rate is hundreds of times faster than that of nitrogen, so the adsorption rate of oxygen on carbon molecular sieve is also very fast, and the adsorption rate reaches more than 90% in about one minute; At this time, the amount of nitrogen adsorption is only about 5%, so at this time, the adsorption is mostly oxygen, and the rest is mostly nitrogen.
The material of the n2 nitrogen generator is carbon steel and the stainless steel. Mostly we choice the carbon steel n2 nitrogen generator.
WORKING PRINCIPLE:
PSA technique (Pressure Swing Adsorption, PSA for short):it's a kind of advanced gas separation technology, based on physical adsorption of gas molecule on the internal surface of adsorbent (porous solid substances), using adsorbents in the same pressure easy to absorb the high boiling point gas, difficult to absorb low boiling point gas, and under high pressure adsorption amount of absorbed gas increases, under low pressure adsorption of absorbed gas to reduce the features to achieve gas separation. This process under pressure adsorption of impurities, under reduced pressure adsorption of impurities, make the adsorbent regeneration, is the PSA cycle.
