Air Separation Unit Air Product

What are the different types of air separation units?
 

Cryogenic distillation air separation unit: Utilizes boiling point difference for liquefaction separation, oxygen purity exceeds 99.5%, nitrogen reaches 99.999%, single set daily production capacity is thousands of tons, energy consumption is high, used for large-scale industrial gas supply such as steel and chemical industry.

Pressure swing adsorption air separation unit: Separation by adsorbent difference, simple process, fast startup, nitrogen purity 95%-99.9%, suitable for small and medium-sized scenarios such as food packaging and medical oxygen production.

Membrane separation air separation unit: Relying on membrane permeation rate separation, the equipment is extremely simple and the energy consumption is low, but the purity is low, mostly used in ultra-small scenarios such as laboratories and medical oxygen enrichment.

Air separation unit Application

Industrial manufacturing:
In the steel industry, oxygen is provided to assist combustion and smelting; in the chemical and petrochemical fields, oxygen, nitrogen and other gases are supplied to participate in chemical reactions and ensure production safety; in metal processing, argon is used for welding protection and nitrogen is used for heat treatment.
Energy industry:
Provide oxygen-enriched air for gas turbines for power generation; assist coal gasification in coal chemical industry; used for equipment purging and inerting in natural gas liquefaction projects.
Medical and food:
Provide medical oxygen in medical treatment; in the food industry, nitrogen is used for fresh-keeping packaging and extending shelf life.


 

1. What is the purity of oxygen and nitrogen that the air separation unit can achieve?
Air Products air separation units use advanced cryogenic distillation technology, and the purity of oxygen can reach more than 99.5%, and the purity of nitrogen can reach 99.999%, meeting the stringent purity requirements of different industries.
 

2. What is the capacity range of the unit, and can it meet our needs?
The capacity covers a wide range, from small 50 tons per day units to large single-series oxygen production facilities with more than 4,000 tons, and single-series 7,000 tons/day units are still under development. The configuration can be flexibly adjusted to adapt to your actual gas needs.
 

3. What are the main aspects of operating costs, and what is the energy consumption level?
The operating costs mainly include power consumption, equipment maintenance, and replacement of adsorbents or membrane components. The company continues to innovate technologies to reduce energy consumption, such as the use of patented new process cycles, which can reduce energy consumption by 10-20% compared with similar products, effectively reducing long-term operating costs.
 

4. When the equipment fails, how fast will the after-sales service respond?
We have a professional team distributed globally, providing 24×7 remote monitoring and on-site services. Once the equipment fails, we will respond immediately, generally provide a solution within 2 hours, and arrive at the site (urban and surrounding areas) within 4 hours to ensure that the device is restored to operation as soon as possible.
