PSA High Purity Mobile Nitrogen Generator
Purity is an important technical parameter of gas. Take nitrogen as an example. According to the purity of national standard nitrogen, it is divided into three grades: industrial nitrogen, pure nitrogen and high-purity nitrogen. Their purity is 99.5% (O2 ≤ 0.5%), 99.99% (O2 ≤ 0.01%) and 99.999% (O2 ≤ 0.001%) respectively.
Purity | 95%-99.999% |
Pressure | 0.1-0.7mpa |
Control | PLC |
Adsorption is the selective concentration of one or more components of gas on the surface of porous solid. The adsorbed components are called adsorption media, and porous solid is called adsorbent. The connecting force between the adsorbent and the adsorption medium is a chemical bond, and the resolution of the adsorption medium depends on heating up or lowering the partial pressure of the component in the air pressure. Another case is that when the adsorption component and the solid adsorbent undergo chemical reaction, it is called chemisorption. Generally, chemisorption cannot be regenerated.
