Air Separation Plant for Nitrogen, Oxygen, Argon
An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes argon and other rare inert gases.
The most common method for air separation is fractional distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.

Manufacturing Process of Air Separation Unit
There are five basic processes for producing oxygen and nitrogen: compression, purification, cooling, separation, and cylinder filling.
Air Compression:
We use the latest air-cooled air compressors to compress the atmospheric air.
The equipment has a suction filter to suck the atmospheric air and leave behind the impurities mixed with it.
Air Purification:
Even after using high-quality air compressors, which have attached suction filters, a few impurities, such as carbon dioxide, dust, etc.,
Get inside the air. Such contaminants are alleviated in this second stage by using a process skid.
Air Cooling:
To make the air liquid, the purified air must be cooled to -165 to -170 degrees centigrade. This is because liquid air gets separated easily.
For this purpose, we have high-end and advanced expenders.
Air separation:
Once the air becomes liquid, the air separation units separate the air into oxygen and nitrogen. We use stainless steel units as they do not react with oxygen and thus guarantee pure outputs.
Cylinder filling by Liquid Oxygen Pumps: This is the last step, where we have liquid oxygen pumps to fill in cylinders at the required pressure. With liquid oxygen pumps, there is no gas loss while cylinders fill in.
