Air separation equipment is a device that uses air as raw material, converts the air into liquid state by means of compression cycle deep freezing, and then gradually separates it from liquid air to produce inert gases such as oxygen, nitrogen and argon through rectification.
More sieve plate towers are used for the lower tower from 15000 to 50000 grades. The diameter tower with circulating tray below 15000 grades has advantages (the liquid flow is longer than convection, but the manufacturing is complex). The convection tower below 30000 grades is used more, the large tower with four overflow streams above 30000 grades has advantages, and the packed tower has low energy consumption.
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.
