Description

Technical Field

[0002] Industrial gas separation is the process of separating the main components of air, such as oxygen, nitrogen, argon, and other rare gases. It primarily uses cryogenic separation methods to separate industrial gases from air by utilizing the boiling point difference between industrial gases and air, as well as the concentration difference at gas-liquid equilibrium. In addition, there is gas separation membrane technology, a selective membrane that can selectively separate specific gases from a gas mixture. Air separation equipment is key to achieving this process and typically consists of a compression system, a pre-cooling system, a purification system, and a distillation system. These devices are categorized by air pressure into high, medium, and low pressure. Low-pressure gas equipment is widely used due to its low power consumption and long continuous operation cycle. The separated industrial gases, such as oxygen, nitrogen, and argon, are widely used in the steel, chemical, and medical industries.
