How do air separation plants work

Brief introduction of air separation plant

Air separation equipment is an equipment that takes air as raw material, turns air into liquid through compression circulation and deep freezing, and then gradually separates from liquid air through distillation to produce inert gases such as oxygen, nitrogen and argon.

Type of air separation unit

There are many forms and types of air separation equipment produced in China. There are devices for producing gaseous oxygen and nitrogen, as well as devices for producing liquid oxygen and nitrogen. But as far as the basic processes are concerned, there are mainly four kinds, namely high-pressure, medium pressure, high-low pressure and full low-pressure processes.

Air separation, in short, is a set of industrial equipment used to separate the components in the air and produce oxygen, nitrogen and argon. There are also rare gases such as helium, neon, argon, krypton, xenon and radon.

Air separation equipment air separation equipment is an equipment that takes air as raw material, turns air into liquid through compression cycle and deep freezing, and then gradually separates oxygen, nitrogen, argon and other inert gases from liquid air through distillation. It is widely used in traditional metallurgy, new briquette chemical industry, large-scale nitrogen fertilizer, professional gas supply and other fields.

In short, the system process of air separation includes:

1. Compression system

2. Precooling system

3. Purification system

4. Heat exchange system

5. Product delivery system

6. Expansion refrigeration system

7. Distillation column system

8. Liquid pump system

9. Product compression system
