The most common production method for separation of oxygen is Air Separation Plants
Separation of Air Components (Air Separation Plant or AS Plant) is a process that captures the basic components of air which are Nitrogen, Oxygen, and Argon, through separation processes
The cryogenic oxygen plant is an industrial facility that electrolytically produces liquid oxygen in large quantities
Cryogenics oxygen plant is used to freeze air or gas into liquid or solid state
PSA oxygen plants produce more pure oxygen than liquid oxygen plants
The most popular of which is the cryogenic distillation technology
There are multitudes of ways to generate nitrogen
Obtaining essential government permissions
It's a component in a range of gas combinations
Cryogenic and PSA technology have unique pricing
