(PSA) is an advanced gas separation technology. High-quality imported carbon molecular sieve (CMS) is used as adsorbent, and the high pressure is obtained by separating the air at room temperature by pressure swing adsorption principle (PSA) Of nitrogen.
The diffusion rate of oxygen and nitrogen gas molecules on the surface of molecular sieve is different, the diffusion rate of gas molecules with smaller diameter is faster, and the diffusion rate of gas molecules (N2) Slow, into the carbon molecular sieve pores less. The use of carbon molecular sieve for nitrogen and oxygen adsorption of this difference, resulting in a short time in the adsorption of oxygen in the adsorption phase, nitrogen enrichment in the gas phase, such as oxygen and nitrogen separation, in the PSA conditions to get gas phase nitrogen.
PSA nitrogen generator (PSA nitrogen generator) is designed and manufactured by pressure swing adsorption technology, the production of nitrogen equipment. Usually using two adsorption tower in parallel, by the automatic control system according to a specific programmable strict control of the timing, alternating pressure adsorption and decompression regeneration, complete nitrogen and oxygen separation, access to the required high purity nitrogen.
