Air separation plants can liquefy and distill air to separate useful gases such as oxygen and nitrogen. When working, the air is first compressed, purified and impurities removed, and then cooled to a deep cryogenic temperature to liquefy it. Taking advantage of the difference in boiling points of various gases, they are separated through a distillation tower, and nitrogen with a low boiling point is vaporized first. The product has high purity and is widely used in scenarios such as medical oxygen supply, nitrogen for food packaging, and argon for welding.

1.Newtek Group
NEWTEK was founded in 1987 and has a history of nearly 40 years. It focuses on air separation and cryogenic technology, providing customized solutions for oxygen, nitrogen, argon, carbon dioxide and special gases. During this period, we continued to focus on gas-related businesses,accumulated technology and experience, and gradually developed from a new enterprise to a world-leading integrated gas company.
At present, we have a variety of products such as Liquid Oxygen Manufacturing Plant, Liquid Oxygen Generation Plant, Co2 Recycling Plant, Co2 Gas Plant,etc., with rich categories.
Air Separation Unit
2.Linde plc
Linde Group's air separation equipment products are rich and varied. Its large-scale air separation units process huge amounts of air and can efficiently produce high-purity oxygen, nitrogen and argon. For example, a certain large-scale unit can process hundreds of thousands of cubic meters of air per hour, and the purity of the oxygen produced can reach more than 99.99%. It is widely used in large-scale gas-using industries such as steel and chemical industry. At the same time, Linde also provides modular small-scale air separation equipment, which is easy to install and transport, suitable for companies with relatively small gas demand. For example, some food processing companies use it to produce nitrogen for food preservation, which can accurately control the gas output and purity to meet the needs of different scenarios.
3.Air Liquide
Air Liquide's air separation products are known for their advanced technology and customized services. For the electronics industry, it can provide ultra-high purity specialty gases, such as nitrogen with a purity of more than 99.9999% for chip manufacturing, meeting the almost stringent requirements of electronic chip production for gas impurities. In the medical field, the medical oxygen produced by Air Liquide's oxygen production equipment meets strict medical standards, from large hospital centralized oxygen supply systems to small medical oxygen generators, to ensure the oxygen supply for medical treatment. During operation, its air separation equipment has intelligent monitoring and regulation functions, which can be flexibly adjusted according to actual gas usage to reduce energy consumption.
4.Air Products and Chemicals
Air Products focuses on innovation in air separation equipment. The high-efficiency and energy-saving air separation equipment it develops uses advanced molecular sieve adsorption technology and a new distillation tower design, which greatly reduces energy consumption. For example, an air separation equipment used in the energy industry saves 15% - 20% energy compared to traditional equipment. While providing a large amount of high-purity hydrogen and oxygen to petrochemical companies, it effectively reduces the company's operating costs. In addition, the company also provides integrated gas solutions, which not only provide air separation equipment and output gases, but also include equipment installation and commissioning, maintenance and gas application technical support, etc., to help customers optimize production processes.
5.Taiyo Nippon Sanso Corp
