Introduction to ASU
Air separation units (ASU) are crucial industrial facilities that separate atmospheric air into its primary components, mainly nitrogen, oxygen, and argon, through a process of cryogenic distillation or other separation techniques. These components have a wide range of applications across various industries. Oxygen is used in steelmaking, chemical production, and medical applications. Nitrogen is employed for inerting in the food and electronics industries, while argon is used in welding and metal fabrication. In China, the development of ASU technology has been remarkable, with many factories producing high - quality ASU equipment to meet both domestic and international demands.
