The PSA Nitrogen Gas Plant was invented about four decades ago by Carbotech GMBH Germany. Carbotech was having hard coal mines initially and later in year 1970 developed a specially designed bottle necked Carbon Molecular Sieves which has the property to adsorb Oxygen from compressed air. Later they developed the technology called PSA (Pressure Swing Adsorption). The Nitrogen has larger diameter of molecules as compared to Oxygen.
- PSA technology is now widely used by almost half the world to manufacture Nitrogen Gas Plants as the compressed air is passed through a dual bed system contains Carbon Molecular Sieves as desiccant and it has a preferential properties for adsorption of moisture first and then Oxygen.
- The adsorbers are being operated at an interval of one minute, one after the other and in re-cyclic mode so that the Nitrogen is produced on continuous basis. Both the Adsorbers are interconnected with 8 valves scheme which operates automatically with the help of sequencer. The nitrogen produced is collected in a reservoir called Surge Tank.
- Further various type of purification systems are being developed in India as well based on customer’s needs. The operating cost is mainly the power and generally 0.6 KW/Nm3/Hr for commercial grade Nitrogen & 0.8 KW/Nm3/Hr for UHP grade Nitrogen.
- Molsieve in to making these plants since 1992 and during these many years Molsieve has continued their innovation and with their patronage invented new ideas which are highly efficient, cost effective, user friendly, maintenance free and having lowest possible impurities in terms of Oxygen & moisture.
