PSA Nitrogen generation plant based on the PSA process consist of two adsorbers filled with carbon molecular sieves, which has the property to absorb Oxygen from compressed air(CMS). Compressed and purified air is passed through the absorbers in this process. Mainly oxygen is absorbed on the carbon molecular sieves as it has preferential properties for adsorption of moisture first and nitrogen enriched gas is leaving the absorber. The oxygen concentration can be reduced to almost all required levels. During adsorption in one adsorber, the second adsorber is totally regenerated just by depressurization to ambient pressure. The oxygen enriched off gas is vented. After about one minute adsorption in one adsorber, the process controller is switching over to the second adsorber to produce nitrogen on a continuous basis.

The DX Model is commonly used in metallurgical industries for providing oxygen free nitrogen for heat treatment furnaces. Here, the oxygen is less than 1-ppm and but hydrogen is around 0.5 to 1% which is desirable as reducing constituent in most of heat treatment applications.
CU-DX Model contains an extra nitrogen purification module based on copper deoxo catalyst. This model finds application in synthetic fiber, optical cables & electronic industries. Running cost of this unit is slightly higher because it produces very pure nitrogen gas i.e free from oxygen and hydrogen as well. It is applicable where hydrogen contents are detrimental to the process.
