Air Separation Unit

Air Separation Unit

Air separation is a process that purifies the gases present in the atmosphere (Nitrogen 78%, Oxygen 21%, Argon 0.9%) to make them suitable for various industrial applications. Air separation plants play a vital role in sectors such as Iron and Steel, Petrochemicals, Energy, Healthcare, and Food.

The gases produced in air separation plants are actively used in the core processes of steel production:

Blast Furnace Operations: Oxygen accelerates the combustion process in blast furnaces, improving temperature control and energy efficiency.

Oxygen Blowing (BOF) Method: High-purity oxygen is used to reduce the carbon content in pig iron during the conversion to steel and achieve the desired alloy characteristics.

Heat Treatment and Cooling Processes: Argon and nitrogen gases are used to improve the microstructure of steel, remove impurities, and ensure controlled cooling.

Welding and Cutting Processes: Oxygen and nitrogen provide high precision in the cutting and welding of steel plates.
