NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to educating our clients on the sophisticated processes that enable high purity nitrogen production, particularly the mechanisms employed by Carbon Molecular Sieves (CMS) in Pressure Swing Adsorption (PSA) systems. The fundamental principle behind nitrogen generation using CMS relies on the size-exclusion properties of its precisely engineered pores. Unlike traditional zeolites that adsorb gases based on polarity, CMS primarily separates molecules based on their kinetic diameter.

Compressed air, a mixture of nitrogen (approx. 78%), oxygen (approx. 21%), and other trace gases, is fed into a vessel containing the CMS adsorbent. Nitrogen molecules, having a slightly larger kinetic diameter than oxygen molecules, diffuse into the CMS pores at a slower rate. Conversely, oxygen molecules, being smaller and having a faster diffusion rate, are preferentially adsorbed by the CMS material, especially at lower pressures. This selective adsorption of oxygen by the carbon molecular sieve is the key to achieving high purity nitrogen.

During the adsorption phase, as oxygen is captured by the CMS, the nitrogen gas flows through the bed and is collected as the product. Once the CMS becomes saturated with oxygen, the vessel is depressurized. This depressurization, or 'swing,' releases the adsorbed oxygen, which is then vented. The rapid release of adsorbed oxygen regenerates the CMS, allowing it to be reused for the next adsorption cycle. This continuous cycle of adsorption and regeneration is the essence of PSA technology, and the efficiency of CMS in these cycles determines the purity and quantity of nitrogen produced.

NINGBO INNO PHARMCHEM CO.,LTD. offers a range of CMS products, including the highly effective CMS 240 molecular sieve, which is optimized for this kinetic separation process. By understanding the precise pore size distribution and surface characteristics of our carbon molecular sieve, we ensure that our clients can achieve optimal performance and consistently high purity nitrogen from their PSA units. Our commitment as a CMS 240 supplier in China extends to providing insights into how our materials contribute to efficient industrial nitrogen production, empowering industries with knowledge and superior products.
