Product Overview
A Steel Oxygen Plant is an advanced industrial oxygen generation system designed to produce high-purity oxygen directly on-site for steel manufacturing and metallurgical applications.
The system uses proven Pressure Swing Adsorption (PSA) or Vacuum Pressure Swing Adsorption (VPSA) technology to separate oxygen from compressed air, ensuring stable, continuous oxygen supply without reliance on liquid oxygen delivery or cylinder logistics.
It is widely used in modern steel plants to improve furnace efficiency, reduce energy consumption, and lower overall oxygen procurement cost.
Typical Applications in Steel Industry:
- Basic Oxygen Furnace (BOF) steelmaking
- Electric Arc Furnace (EAF) operations
- Ladle Refining Furnace (LRF)
- Scrap melting and reheating systems
- Oxygen-enriched combustion systems
Engineering Principle
The system operates through a fully automated cyclic adsorption process:
Air Compression
Industrial screw air compressors provide clean compressed air.
Air Purification System
Multi-stage purification removes:
- Oil particles
- Moisture
- Dust and impurities
Oxygen Separation
Air enters twin adsorption towers filled with Zeolite Molecular Sieve (ZMS):
- Nitrogen is selectively adsorbed
- Oxygen is separated as product gas
Pressure Swing Cycle
- One tower produces oxygen
- The other regenerates automatically
Oxygen Storage & Supply
Oxygen is buffered and delivered at required pressure for industrial use.
This process ensures continuous 24/7 oxygen output with stable purity and pressure.
