Nitrogen is one of the most widely used gas for purging, pressuring & blanketing applications.
What is Nitrogen and How is it Produced
Nitrogen (N2) is a colorless, odorless gas which makes up roughly 78% of the earth’s atmosphere. Nitrogen is defined as a simple asphyxiant having an inerting quality which is utilized in many applications where oxidation is not desired.
Nitrogen gas is an industrial gas produced by one of the following means:
Fractional distillation of liquid air (Praxair, Air Liquide, Linde, etc)
By mechanical means using gaseous air
Polymeric Membrane
Pressure Swing Adsorption or PSA
Nitrogen gas generator produces nitrogen gas from atmospheric air based on PSA (Pressure Swing Adsorption) technology. We provide variety of PSA Nitrogen gas generator, Nitrogen Plant, in all kind of industries such as Chemicals, Pharmaceuticals, Bulk Drugs, Food, Electronic Industry, Steel, Coal Mines, etc. PSA technique is simple and reliable process of separation of nitrogen gas form compressed air by adsorption of oxygen over a compact tower of carbon molecular sieves.
The “Treated” atmospheric compressed air enters an adsorption tower where it comes in contact of carbon molecular Sieves that binds the oxygen molecules and allows nitrogen to pass through void space. Pure nitrogen flows product delivery operation and once the oxygen capturing capacity in a bed is diminished the feed switches to a new adsorption tower and the old bed is regenerated through rapid depressurization and is ready for the next cycle.
PSA Nitrogen system comprises of four main operations :
Air Compression → Air Pretreatment → Adsorption / Desorption → Product Delivery
Nitrogen PSA Plant Working Principle
Nitrogen generation plant based on PSA technology consists of 2 absorber tower filled with Carbon Molecular Sieve (CMS). When pre-filtered & compressed air is passed through the one adsorber, oxygen is adsorbed on the CMS and nitrogen gas comes out as the product gas. The waste gas (Oxygen, C02, etc.) is discharged back into the atmosphere through silencer.
During adsorption in one tower the second tower regenerates through depressurization to atmospheric pressure. This ensures continuous supply of Nitrogen gas to your process.
