Air separation equipment refers to a device that uses air as raw material to separate various gases such as oxygen and nitrogen in the air by cryogenic separation or adsorption separation. The air separation plant is mainly composed of eight systems, namely compression system, purification system, refrigeration system, heat exchange system, rectification system, product conveying system, liquid storage system and control system.
Strictly speaking, the heat exchange system is designed with multi stream mixed media in the same heat exchanger, so that the heat transfer of each medium is automatically balanced and the energy consumption is the lowest. However, for the internal compression process, all heat exchangers will be high-pressure heat exchangers, which will increase the accumulation of investment.
You are no stranger to all kinds of compressors and steam turbines, but do you really understand their role in air separation? Do you know what the air separation workshop in the factory is like? Air separation, in short, is a set of industrial equipment used to separate the components in the air and produce oxygen, nitrogen and argon. There are also rare gases such as helium, neon, argon, krypton, xenon and radon.
