In the Process of generating Nitrogen, Carbon Molecular Sieve (CMS) plays a very vital role. With the help of CMS only Nitrogen is produced. CMS takes up the oxygen, carbon dioxide and other impurities and release the pure nitrogen.
PSA is one of the unique processes in which gases are separated with the help of pressure swing technology is called PSA. In this process when the bed is in desorption mode with the help of release pressure it is been regenerated and then to swing to adsorption mode.
There are two towers available in the process. One tower acts as adsorption mode, and other acts as desorption mode. As soon as adsorption tower reaches to its equilibrium, it switches to desorption mode and desorption tower which has been totally active comes to adsorption mode. Thus this cycle keeps on shifting from adsorption to desorption and desorption to adsorption mode.
Thus adsorption and desorption give continues Nitrogen generation. Once CMS bed is saturated with the Oxygen and Carbon Dioxide, it will be ready for the desorption process.
