Cryogenic Air Separation Unit

 

High-purity gas output: Through deep cryogenic distillation technology, the cryogenic air separation unit can stably produce oxygen with a purity of ≥99.5%, nitrogen with a purity of ≥99.99%, and argon with a purity of ≥99.97%, meeting the stringent requirements of semiconductor, medical and other high-tech industries for gas purity.

Large-scale and efficient production: The processing capacity of a single set of equipment can reach 100-100,000 Nm³/h, which is suitable for large-scale continuous gas supply scenarios. Through the double-tower distillation system and turbo expander to recover energy, energy consumption is reduced by more than 20%, taking into account both production capacity and economy.

Full-process intelligent control: Integrated digital control system, real-time monitoring of key parameters such as pressure, temperature, purity, etc., supports remote adjustment and fault warning, ensures stable operation of equipment, and reduces manual operation and maintenance costs and operational risks.

Modular and flexible adaptation: The standardized module design can quickly adjust the gas production capacity and purity ratio according to user needs, compatible with different gas source conditions, and achieve rapid deployment and later capacity expansion.

 

 

 

application of cryogenic air separation unit

Iron and Steel Metallurgy: Provide high-purity oxygen for the steelmaking process, accelerate the decarbonization reaction of molten iron, and improve smelting efficiency; use nitrogen to protect the ladle and prevent metal oxidation, help produce high-quality steel, and reduce impurity content.
Chemical and petrochemical: In the processes of synthetic ammonia and ethylene cracking, nitrogen is supplied as a protective gas, oxygen is used to strengthen the reaction, and argon is used to protect the catalytic process to ensure the stability and safety of chemical production.
Medical health: Produce medical oxygen that meets ISO 10083 standards, provide pure breathing gas sources for hospital ICUs, emergency equipment and hyperbaric oxygen chambers, and use liquid nitrogen for cryopreservation and transportation of biological samples.
Electronic semiconductors: Provide ultra-pure nitrogen (99.999%) for clean process environments such as chip etching and photolithography to prevent oxidation and contamination; high-purity argon is used as a carrier gas for sputtering processes to ensure high-precision manufacturing of semiconductor devices.

1. Can the purity of the gas produced by the equipment meet the needs of the semiconductor industry?
It can stably produce ≥99.999% high-purity nitrogen and ≥99.97% argon, which fully meets the stringent requirements of semiconductor manufacturing for clean gas sources, and supports customized purity adjustment.

2. Does the equipment failure affect the continuous gas supply?
The system is equipped with redundant design and intelligent early warning system, and can automatically switch to the backup module when the key components fail; at the same time, it provides 7×24 hours after-sales response, and on-site maintenance within 48 hours in emergency situations to ensure uninterrupted gas supply.
 

3. Does the equipment support later capacity expansion?
With a modular architecture, users can flexibly add modules such as distillation towers and compressor units according to their needs, and can achieve capacity improvement without large-scale transformation, which is suitable for the long-term development needs of enterprises.
 

4. How complicated is the equipment maintenance?
The intelligent control system monitors the operating parameters in real time and automatically generates maintenance reminders; the core components (such as molecular filters and heat exchangers) adopt a quick-disassembly design, which can be operated by ordinary maintenance personnel after training, reducing professional dependence.
