1. Introduction

Industries today use pure industrial gases extensively. This is why industrial air separation plant is crucial for generating oxygen, nitrogen, and argon.

Steel making, chemicals, health care, and electronic industries use these gases. Therefore industrial air separation plants are crucial installations.

2. What Is an Industrial Air Separation Plant 

An industrial air separation plant takes atmospheric air and separates it into its components.

Main components are listed below.

* Oxygen (O₂)

* Nitrogen (N₂)

* Argon (Ar)

3. The Principle of Operation of Industrial Air Separation Plants

The principle of operation of the air separation plant: separates air according to physical properties.

Step 1: Air compression

The air is compressed so that the pressure increases.

Step 2: Air purification

The compressed air is purified from impurities such as moisture, CO2 and oil.

Step 3: Cooling or Adsorption

Depending on the type of system:

Either cryogenic cooling => liquefaction occurs.

Or PSA/VPSA adsorption => nitrogen is removed.

Step 4: Separation of gases

The air is divided into oxygen, nitrogen and argon.

Step 5: Storage and distribution

The separated gases are stored or supplied directly to industrial customers.

Conclusion: The system is designed for continuous supply of gases.
