Air Separator Unit

The air separator unit is a core equipment for efficient gas separation. It uses cryogenic distillation, pressure swing adsorption or membrane separation technology to accurately separate oxygen, nitrogen, argon and other components in the air. Its core system includes a compression purification module to remove impurities and optimize the gas source; the distillation/separation module uses the characteristics of the components to achieve efficient separation; and the intelligent control system dynamically adjusts parameters to ensure stable operation. The equipment can output 99.5% - 99.999% pure gas, which is suitable for many fields such as steel, medical, and electronics. It has the advantages of high production capacity and low energy consumption, and provides reliable gas solutions for industrial production and people's livelihood needs.

Description

Technical Parameters

Main types

●Cryogenic distillation type:
suitable for large-scale, high-purity gas production, can produce high-purity oxygen, nitrogen and argon, etc., widely used in industries such as steel and chemical industry that require high gas purity.

●Pressure swing adsorption type:
simple equipment, quick start-up, can flexibly adjust gas output according to demand, but the product purity is lower than that of cryogenic distillation type, and is often used in occasions where gas purity requirements are not particularly high, such as small oxygen and nitrogen production.

●Membrane separation type:

compact device, easy operation, low energy consumption, but limited separation effect, mainly used in some scenarios where gas purity requirements are not high and gas consumption is small, such as nitrogen for food preservation and small medical oxygen.

work principle

Raw gas pretreatment

After being compressed, precooled and dehydrated, the air enters the purification system to remove impurities such as carbon dioxide to ensure the cleanliness of the gas source.

Low-temperature distillation separation

After the clean air is liquefied, it enters the distillation tower, and high-purity separation is achieved through gas-liquid exchange by utilizing the boiling point differences of oxygen, nitrogen, argon, etc.

Pressure swing adsorption separation

Relying on the pressure-sensitive characteristics of the adsorbent to the gas, separation is completed by pressure switching, which is suitable for small and medium-scale production.

Membrane separation technology:

Using the difference in the permeation rate of polymer membranes to gases, oxygen, nitrogen and other components are separated, and the device is compact and low in energy consumption.

FAQ

1. What is the purity and output of oxygen and nitrogen produced by the air separation unit? Can it meet our production needs?
Our air separation units can provide a variety of purity and output specifications. The purity of oxygen can usually reach more than 99.5%, and the purity of nitrogen can be as high as 99.999%. In terms of output, it ranges from a small scale of several hundred cubic meters per hour to a large scale of tens of thousands of cubic meters per hour. We will accurately recommend the appropriate device model based on your specific production gas needs, including hourly and daily usage, as well as purity requirements, to ensure that it fully meets your production scale and quality standards.

2. What is the energy consumption of the device operation? Is the operating cost high after long-term use?
We pay great attention to energy consumption control and adopt advanced energy-saving technologies and optimized process flows. For example, the use of high-efficiency compressors, new distillation tower structures and energy-saving refrigeration systems can reduce energy consumption by 15%-25% compared with traditional equipment. Operating costs mainly cover power consumption, equipment maintenance, etc. We can provide you with a detailed cost analysis, based on the energy consumption data and maintenance cycle of the device, clearly showing the long-term operating costs, and helping you to control costs.

3. How stable and reliable is the equipment, and how often is a failure likely to occur?
Our air separation units are designed and manufactured with high-quality materials and advanced processes, and are strictly quality tested. Under normal circumstances, the average trouble-free operation time can reach 8,000-10,000 hours. At the same time, we have built a complete preventive maintenance system, through regular inspections, condition monitoring and other means, to detect and solve potential problems in advance, ensure stable operation of equipment, and greatly reduce the probability of failure.
