asu in steel plant Detailed description
Non-contact dispensing technology
Excellent Energy Efficiency and Low Operating Costs: Energy consumption accounts for over 70% of an air separation unit's total operating costs. Our ASU utilizes several patented technologies to achieve extreme energy savings:
High-Efficiency Molecular Sieve Purification System: Reduces adsorption resistance, minimizes regeneration gas loss, and improves purification efficiency.
Advanced Structured Packing Distillation Column: Significantly reduces internal column resistance, significantly compressing the main air compressor's discharge pressure, thereby significantly reducing compression energy consumption.
Air Booster and Expander Refrigeration Process: Optimizes the refrigeration cycle, fully utilizing pressure differential energy for efficient refrigeration.
Key Application Scenarios
Blast Furnace Ironmaking: Oxygen-enriched blast increases furnace temperature, accelerates combustion reactions, and significantly increases pig iron production while reducing coke consumption.
Converter/Electric Furnace Steelmaking: Ultra-high-purity oxygen is injected into molten iron to oxidize and remove impurities such as carbon, silicon, manganese, and phosphorus, a core step in modern steelmaking.
Refining Furnaces (such as AOD and LF): Argon and nitrogen are used for stirring to achieve uniform composition and temperature, further removing harmful gases such as hydrogen and oxygen, and improving steel purity.
Continuous Casting: Nitrogen is used as a shielding gas to prevent air oxidation of high-temperature molten steel during the casting process, ensuring surface quality of the ingots.
Comprehensive Applications in Steel Plants: Nitrogen is widely used for pipeline purging, pneumatic conveying, instrument gas, and safety inerting. Liquid oxygen and liquid nitrogen can also serve as backup gas sources, ensuring uninterrupted plant-wide air supply during maintenance of the main ASU.
