Cryogenic Low Purity Oxygen-Enriched Air Separation Unit (ASU)
This unit can produce low-purity oxygen with adjustable purity ranging from 80% to 93%, while simultaneously generating high-purity oxygen (99.6%), high-purity nitrogen (99.999%), instrument air, compressed air, liquid oxygen, liquid nitrogen, and other gas products. It features high efficiency, energy savings, and multi-product co-production, making it suitable for gas supply needs across various industrial sectors.
This unit is widely used in the following industries:
● Precious Metal Recovery
● Non-Ferrous Metal Smelting
● Glass Manufacturing
● Energy Sector
● Chemical Industry
Top-blown furnace (7,000Nm3/h)
1. Multi-Product Supply：
A single unit can simultaneously produce multiple gas products, meeting different process requirements and reducing equipment investment and footprint, including：
·Low-purity oxygen (adjustable from 80% to 93%) ·Liquid nitrogen
·High-purity oxygen (99.6%) ·Liquid oxygen
·High-purity nitrogen (99.999%) ·Compressed/Instrument air
2.Lower Energy Consumption
Low-carbon and environmental-friendly with 5-10% reduced energy consumption.
3.Self-Produced Liquids, Reliable Gas Supply
The system can self-produce liquid oxygen and nitrogen, which can be directly used for the backup system, eliminating the need for external procurement and enhancing gas supply stability and reliability.
4.Lower Noise
Specially optimized for low-frequency noise control, operation is quieter with minimal environmental impact.
5.Strong Operational Flexibility, High Adaptability
Load adjustment range is 75%–105%, expandable to 25%–105% when configured with two compressors, adapting to various production conditions.
6.Larger Single-Unit Capacity
The maximum capacity of a single unit can reach 100,000 Nm³/h, significantly higher than a single VPSA oxygen generation unit (max. 4,000 Nm³/h).
7.Lower Cost
CAPEX is 30% lower than same capacity VPSA and occupies 10% less space.
8.Lower Maintenance Cost
With an optimized structure and simplified maintenance, the lifecycle maintenance cost is significantly lower than comparable equipment.
• Flexibility: Easy vehicle transportation and relocation between gas sources
• Stability: Consistent equipment selection and standardized production
• Convenience: Rapid delivery, streamlined installation, same-month commissioning and production
• Versatility: Enhanced load adjustment capability, compatible with various gas compositions and pressures
