Background
PSA is a new gas separation technology, taking adsorbent molecular sieve as an example, and the principle is to separate gas mixture by utilizing the difference of adsorption performance of molecular sieve to different gas molecules. The method takes air as a raw material, and separates nitrogen and oxygen in the air by utilizing the selective adsorption performance of a high-efficiency and high-selectivity solid adsorbent on the nitrogen and the oxygen. The separation effect of the molecular sieve on nitrogen and oxygen is mainly based on the fact that the diffusion rates of the two gases on the surface of the molecular sieve are different, and the gas with the smaller diameter has faster oxygen diffusion and more oxygen enters the solid phase of the molecular sieve.
