Air Separation Equipment work principle
Cryogenic distillation
Air is compressed and deeply cooled to separate gases and nitrogen at different boiling points.
Pressure swing adsorption (PSA)
Separation is achieved by cyclically increasing and decreasing pressure using differential molecular adsorption of oxygen and nitrogen.
Membrane separation
Oxygen and ammonia are separated by differential diffusion rates through a selectively permeable membrane.
Cryogenic liquefaction
After air is liquefied, precise separation is achieved using the evaporation temperature differences of the components.
Air Separation Equipment Application
● Metallurgy and Steel Industry
Oxygen is used in blast furnace ironmaking, converter steelmaking, cutting, and welding.
Ammonia serves as a shielding gas and anti-oxidant to ensure stability during smelting and heat treatment.
● Chemical and Petrochemical Industry
Oxygen is used in chemical synthesis (such as synthetic ammonia, ethylene, and methanol production).
Ammonia serves as an inert shielding gas for the safety of chemical storage tanks and pipelines.
Argon is widely used in specialty chemical reactions.
● Energy and Environmental Protection
Oxygen is used in coal gasification and waste incineration power generation to improve combustion efficiency.
Ammonia is used in power plant cooling systems, fuel storage, and transportation protection.
Air separation units also play a key role in carbon capture and environmental treatment projects.
● Medical and Pharmaceutical Industry
Medical oxygen is used for hospital oxygen supply, respiratory therapy, and surgical anesthesia.
High-purity ammonia is used for shielding atmospheres and packaging in pharmaceutical production.
