Nitrogen Gas Generator By Airro Engineering Co.

Nitrogen Gas Generators produces Nitrogen gas from atmospheric air by PSA (Pressure Swing Adsorption) Technology. PSA Technique is a simple & reliable process of separation of Nitrogen from compressed atmospheric air by adsorption of oxygen over a bed of Carbon Molecular Sieves (CMS). CMS is an adsorbent having infinite number of small pores. The diameter of the Bottle Necks is in the same range as those of the molecules.
Thus when CMS is used in the PSA process, an Oxygen Molecule, having a smaller diameter than a Nitrogen molecule traps in to the pores. Therefore the Nitrogen is recovered to a high degree while almost all the oxygen is adsorbed.

PROCESS

The production of Nitrogen gas from Atmospheric Air is based on Pressure Swing Adsorption (PSA) principle by adsorption of oxygen gas using a special grade of imported Carbon Molecular Sieves (CMS).
Atmospheric air is compressed by an Air Compressor to a pressure of 7.0 kg/cm2g and cooled to ambient temperature in a shell and tube type heat exchanger. The condensed moisture shall be drain out automatically from air receiver by automatic drain valve (ADT). The compressed air at ambient temperature is passed through PSA module packed with activated alumina and special grade of Carbon Molecular Sieves. The production of Nitrogen from air by PSA technology is largely based on the kinetic separation. Oxygen that is smaller in size (kinetic diameter 3.46 A0) diffuses much faster than Nitrogen (kinetic diameter 3.64 A0) and he
