Argon extraction for small air separation units

Argon extraction for small air separation units
The main tower of the air separation equipment is a prerequisite for the normal working conditions of the argon tower, while the good or bad runoff conditions of the rough argon tower will also affect the stability of the working conditions of the main tower.

In the air separation plant, the purity of oxygen is mainly determined by the working conditions of the distillation column at the upper and lower parts. In addition, the oxygen content in argon fraction, reflux ratio, number of theoretical trays and separation efficiency will have a direct impact on the purity of oxygen. The following is a brief introduction to the relationship between these factors and oxygen purity.

Oxygen (including liquid oxygen) is one of the main products of small air separation units, but also a strong accelerant and strong oxidant. Grease, fibres and metals can become combustible in a high oxygen concentration. Once the valve housing for oxygen leaks out, oxygen leakage may lead to deflagration or explosion. Valves for oxygen in small air separation units as well as cryogenic valves require non-destructive testing of the pressure-bearing parts of the valve body for technical requirem...
