Nitrogen is presently being used in a broad spectrum of industries, laboratories, tank farms, mines, etc. In most applications, the N2 pressure required is less than 6 bar. Despite this, high pressure N2 cylinders are commonly used as source of N2, whose handling is quite hazardous & risky. A better option would be to produce your own low pressure N2 by installing our Nitrogen Generator.
How do I produce my own N2 ?
Low pressure N2 can be produced by separating oxygen and nitrogen in air by using the Pressure Swing adsorption (PSA) process. Dry, oil-free compressed air at around 7.5 bar pressure enter the PSA System where the oxygen is adsorbed by the Carbon Molecular Sieves and pure nitrogen comes out as a product gas. The N2 (pressure of around 6 bar) is stored in a Receiver and drawn for use, whenever required. Necessary measurement and control devices are incorporated to make the N2 Generator fully automatic as well as to ensure that only pure N2 goes to your User equipment.

The PSA Oxygen Generation System produces oxygen suitable for many applications such as brazing/soldering, ozone generation, chemical oxidation, fermentation, waste water & sewage treatment, healthcare, glass & neon manufacture, pulp & paper, furnace air enrichment, preheating of metals, battery manufacture, metal smelting , etc . The PSA Oxygen Generation System consists of two parts – Dry Air System where dry & oil-free compressed air is produced by filters & Dryer and the other is the PSA System where O2 is produced and stored. In the PSA System, dry & oil-free compressed air is passed through a bed of Zeolite Molecular Sieves (ZMS) which has a property of very high degree of affinity to nitrogen, which it retains & releases oxygen as product gas. There are two adsorbers filled with ZMS with one in production cycle while the other is regenerated by depressurization. The two adsorbers are switched from adsorption to desorption automatically. For large capacity systems, a VPSA System is used, where adsorption is done at low pressure and the regeneration is done by vacuum. This helps in reducing power consumption substantially.
The PSA Oxygen Generation System is an economical option to both liquid O2 and O2 cylinders because here the O2 is produced in-house and you do not have to be dependant on outside sources of supply. It also eliminates risks & hazards of handling high pressure cylinders & Dewar flasks. |
