High purity characteristics of gas cryogenic air separation unit
Professional gas cryogenic air separation plant manufacturer
The gas cryogenic air separation unit can produce high-purity gas, thanks to its working principle based on cryogenic distillation. In a low-temperature environment, the boiling point differences of the various components of air can be fully utilized. Taking the separation of oxygen, nitrogen and argon as an example, the boiling point of oxygen is -183°C, the boiling point of nitrogen is -196°C, and the boiling point of argon is -186°C. By precisely controlling the temperature and pressure in the distillation tower, different gases evaporate and condense at different stages, achieving efficient separation, and thus obtaining high-purity products.
In actual production, the oxygen purity produced by this device can usually reach more than 99.5%. Even in some electronics, medical and other industries that require extremely high oxygen purity, the oxygen purity can be increased to more than 99.9% by optimizing processes and equipment. High-purity oxygen is crucial in the medical field and can be used for emergency treatment, intensive care, etc. to protect the life and health of patients; in the electronics industry, it is used in oxidation, photolithography and other processes in the semiconductor manufacturing process to ensure the high quality and stability of electronic components.
The purity of nitrogen is also excellent, generally reaching more than 99.9%. In some high-end application scenarios, such as high-end chip manufacturing, scientific research experiments, etc., the purity can be further increased to more than 99.999%. High-purity nitrogen is used as a protective gas in the electronics industry to prevent oxidation and contamination during chip manufacturing; in the food packaging industry, it is used to fill packaging and extend the shelf life of food.
The purity of argon can also reach more than 99.99%. In the field of welding, high-purity argon is used as a protective gas to effectively isolate the air, prevent oxidation of the welding part, and improve the welding quality; in semiconductor manufacturing, it is used for processes such as crystal growth and sputtering to ensure the performance of semiconductor devices.
The production capacity of high-purity gas produced by the NEWTEK gas cryogenic air separation plant is of great significance to various industries. In the steel industry, high-purity oxygen is used for converter steelmaking, which can accelerate the oxidation of impurities in molten iron, improve steelmaking efficiency and steel quality; high-purity nitrogen is used for furnace protection atmosphere to prevent molten steel from being oxidized at high temperatures and improve the performance of steel. In the chemical industry, high-purity gases are used as raw materials or reaction media to participate in various chemical reactions to ensure product quality and yield. In the electronics industry, high-purity gases are a key factor in ensuring high precision and high performance of electronic products. With the continuous development of electronic technology, the requirements for gas purity are becoming higher and higher. The high-purity production capacity of gas cryogenic air separation units provides strong support for the development of the electronics industry.
