Carbon molecular sieve Description

Carbon molecular sieve is a new kind of adsorbent, which is an excellent non-polar carbon material. It is mainly composed of elemental carbon and appears as a black columnar solid.

Carbon molecular sieve contains a large number of micropores, these micropores on the instantaneous affinity of oxygen molecules is strong, can be used to separate O2 and N2 in the air. In industry, pressure swing adsorption device (PSA) is used to make nitrogen.

Carbon Molecular Sieve is used for Nitrogen Generation. Nitrogen Generation can be done by the PSA process. Carbon Sieve plays a very great role in this. Mainly Adsorption, as well as desorption, is the physical phenomena there into the process.As shown in the figure, the CMS Carbon Sieve has a very huge porous structure. It will be adding more surface area to the adsorption process.

In the Air almost near about 78% Nitrogen (N2) and about 20% Oxygen (O2) is there. Now if we magnifying the CMS to view the solid surface of CMS, in that spongy structure is there. CMS has a special affinity towards the Oxygen Molecules. Thus Oxygen molecules are been adsorbed by the Carbon Molecular Sieve and Nitrogen cannot be adsorbed. If we pass the compressed air through the bed of CMS, Oxygen will be adsorbed in the spongy structure and Nitrogen will be passed through the bed. This can be achieved by applying air with pressure. Gradually the bed of CMs will be saturated and reached to its equilibrium state. At this point, if pressure drops to an atmospheric level with the purging of pure Nitrogen gas, the bed of CMS will be coming to active mode by desorption of Oxygen. The adsorption and desorption give the continue flow of Nitrogen.

Service life of carbon molecular sieve

The service life of a carbon molecular sieve (CMS) can vary depending on various factors such as the quality of the material, the operating conditions, and the application. However, in general, CMS can last for several years with proper use and maintenance.

CMS is typically used for gas separation applications, where it selectively adsorbs certain gas molecules while allowing others to pass through. The material's service life is affected by factors such as the gas composition, temperature, pressure, and the frequency of regeneration cycles.

Generally, CMS can maintain its performance for several years, and its service life can be extended by following proper operating procedures such as avoiding exposure to moisture and high temperatures, using appropriate regeneration procedures, and periodically monitoring its performance. However, over time, the CMS material can degrade due to thermal and chemical stresses, resulting in a reduction in its separation performance.

The actual service life of CMS will depend on the specific application and operating conditions. It is essential to monitor the CMS's performance regularly and replace it when its performance deteriorates significantly to ensure optimal operation and maintain product quality.
