Low Pressure Air Separation Unit

 

Low Pressure Air Separation Unit Features

Low energy consumption

low pressure process is adopted to reduce compression power consumption and save energy.
High safety

low pressure environment reduces the risk of flammability and explosion, and the operation is more stable.
Simplified equipment

compared with high pressure equipment, the structure is more compact and maintenance is more convenient.
Faster start-up

process design is optimized, and the time to reach stable operation is shorter.
Adapt to small and medium scale

suitable for small and medium gas volume needs, with strong flexibility.
Adjustable purity

the purity of oxygen, nitrogen and other products can be adjusted according to demand, with wide applicability.

 

Low Pressure Air Separation Unit Application Scenarios

Small and medium-sized chemical plants

Due to the need for small- and medium-sized oxygen and nitrogen supply, low-pressure air separation units have low energy consumption and simple equipment, which are suitable for production needs. ​
Food preservation workshop

Adjustable purity nitrogen is required, low-pressure devices are easy to adjust, and they can start quickly and respond quickly to intermittent nitrogen use. ​
Remote mining area oxygen supply

The site is limited and safe operation is required. Low-pressure equipment is compact and low-pressure environment reduces risks, which is suitable for field conditions. ​
Laboratory gas preparation

The requirements for gas purity vary, the purity of the device is adjustable, and the maintenance is convenient, which is suitable for small batch flexible production. ​

Q: What is the oxygen production range of this low-pressure air separation unit? Can it meet the production needs of our factory? ​
A: The oxygen production range of this device can be adjusted according to different working conditions. You can provide the factory's hourly oxygen demand, peak fluctuation and other data, and we will evaluate whether it matches for you. If there are special needs, we can also customize equipment with relevant parameters. ​

Q: Can the existing site of our factory accommodate the installation? ​
A: It is recommended that you provide the floor plan and size restrictions of the factory site. Our technical team can conduct on-site surveys and design reasonable installation plans. ​

Q: What is the purity of nitrogen produced by the device? Can it meet the different purity requirements of oxygen and nitrogen at the same time? ​
A: The purity of oxygen and nitrogen can be adjusted separately according to demand. By optimizing parameters such as the reflux ratio in the distillation tower, it can meet the gas demand of different purities at the same time.

​
Q: What are the requirements of the equipment for the quality of the incoming air? If the dust content or humidity in the air is high, is it necessary to equip additional pretreatment equipment?​
A: The device requires the dust content of the incoming air to be ≤1mg/m³ and the relative humidity to be ≤80% (at room temperature). If the air quality on site is poor, it is recommended to use pre-treatment equipment such as high-efficiency air filters and freeze dryers. We can provide an integrated pre-treatment solution to ensure stable operation of the equipment.
