Cryogenic Air Separation Plants for Industrial Gas Production
Dec 23 , 2025The demand for industrial gas is steadily increasing around the world. Reliable production technology is therefore required. Cryogenic air separation plants can provide large volumes of high-purity gas. In addition, they ensure stable and continuous operation of industrial production. For this reason, high purity and large capacity make cryogenic technology the industry standard.
Nanjing Bangwin Gas can supply customers with highly advanced gas generation and gas separation technology. Therefore, users can realize a stable and efficient supply of gas.
Liquid Nitrogen Generation Plant
Cryogenic air separation plants separate air into oxygen, nitrogen and argon by distillation at low temperatures. As a result, each gas can achieve a very high degree of purity.
Large-scale industrial gas supply projects are the main application of these plants. For this reason, steel mills and chemical complexes often use cryogenic systems.
Air Liquide – Air Separation Technologies
The sequence is strictly in order and continuous.
l Air Compression and Purification
The machine compresses atmospheric air. Filters in the system eliminate dust, moisture, and hydrocarbons.
l Cooling and Liquefaction
Heat exchangers cool down the air to cryogenic temperatures. Consequently, the air liquefies.
l Fractional Distillation
The liquefied air is fed into distillation columns. Oxygen, nitrogen, and argon separate due to their boiling points.
l Product Collection
The plant collects the separated gases as liquid or gaseous products. Storage systems are in place to handle distribution.
This process ensures a stable output and consistent product purity.
A cryogenic air separation plant typically consists of the following parts:
l Air compressor
l Air purification unit
l Main heat exchanger
l Cold box
l Distillation columns
l Liquid oxygen tank
l Liquid nitrogen tank
l Argon recovery system
l Control and safety system
Nanjing Bangwin Gas combines these components with an optimized layout. Therefore, the plant can achieve high efficiency.
Cryogenic air separation plants produce various industrial gases.
l Main Products
l Oxygen (LOX or GOX)
l Nitrogen (LIN or GN₂)
l Argon (LAR or GAR)
l Optional Products
l Rare gases
l Instrument grade nitrogen
High purity enables critical applications of these gases.
Cryogenic air separation plants have many advantages.
l High Purity of Gases
Achieves purity up to 99.999%. Therefore, the plant satisfies highly demanding industries.
l High Production Capacity
The system can manage very high flow rates.
l Multi-Gas Production
The plant can produce oxygen, nitrogen, and argon at the same time.
l Steady Continuous Operation
Supports 24-hour operations with little variation.
l Long Lifetime of Equipment
The design is robust, ensuring long-term reliability.
Cryogenic air separation plants are widely used to support many industries.
l Major Applications
l Steel and metallurgy
l Chemical processing
l Petrochemical plants
l Glass manufacturing
l Electronics production
l Energy and power generation
l Hydrogen production support
Scale and purity continue to make cryogenic plants important.
Different gas production methods serve different needs.
