Product Overview
Liquid Air Separation Unit are industrial gases obtained by separating and liquefying components such as nitrogen, oxygen, and argon from air using cryogenic air separation technology. Due to their high purity and ease of storage and transportation, these products are widely used across various sectors of modern industry.
Product Details
1. Product Specifications
The Liquid Air Separation Unit is specifically designed to meet diverse industrial needs, offering a wide range of capacity adjustments and exceptional operational stability. The specific technical specifications are as follows:
Output Specifications
| Product Name | Typical purity indicators | Critical impurity limits | Common Applications |
| Liquid oxygen (LOX) | ≥ 99.6% ≥ 99.6% | There are typically no strict limits on argon content (as an accompanying component), but moisture and carbon dioxide must be kept to an absolute minimum. | Steel smelting, chemical oxidation, healthcare |
| Liquid nitrogen (LIN) | ≥ 99.999% (5N) ≥ 99.999% (5N) | Oxygen content ≤ 3 ppm (parts per million) | Electronics and semiconductors, frozen foods, inert gas protection |
| Liquid argon (LAR) | ≥ 99.999% (5N) | Oxygen content ≤ 2 ppm; Nitrogen content ≤ 3 ppm | Stainless steel welding, monocrystalline silicon pulling, and specialty metal smelting |
- Production Specifications: All-liquid units; specially designed air separation units that produce only liquid products, with a total liquid production capacity ranging from 10 TPD to 1,200 TPD.
While producing pipeline gas, large-scale air separation units also extract a portion of the liquid; typically, the liquid yield accounts for no more than 20% of the gas yield.
2. Product Advantages
(1) Large-scale of economical efficiency
A single unit of equipment can produce several thousand tons of liquid oxygen per day, and energy consumption per unit of product decreases significantly as scale increases, making it suitable for large gas companies or enterprises with high gas consumption to establish their own liquid oxygen production facilities.
(2)Energy Conservation and Reduction of Resource Consumption
The unit features high argon extraction efficiency and low energy consumption; through the use of advanced processes and equipment, it has achieved significant energy savings and reduced consumption.
(3)Stable operation, secure supply
Cryogenic air separation units are typically designed to have a service life of more than 20 years and are capable of long-term, continuous, and stable operation. Additionally, liquid products can be stored in vacuum-insulated cryogenic storage tanks, creating a reliable gas reserve that ensures uninterrupted gas supply even in emergencies, thereby significantly enhancing gas supply safety.
