Air Separation Equipment Production of air separation equipment in various forms. There are devices for producing gaseous oxygen and nitrogen, and there are also devices for producing liquid oxygen and nitrogen. But as far as basic processes are concerned, there are four main types, namely, high pressure, medium pressure, high pressure, and low-pressure processes.
Why should impurities be removed in the air separation process? As the air cools, the frozen water and carbon dioxide are deposited in low-temperature heat exchangers, turboexpanders or rectification towers, which will block channels, pipelines and valves; acetylene accumulates in liquid oxygen and has the risk of explosion ;Dust will wear out the
Why should the air separation equipment be defrosted? Long running time, coupled with multiple starts and stops, some parts of it will be frozen by moisture. In this case, the heat exchange effect will be worse, the resistance will increase, which will reduce the output and increase the energy consumption, so thorough Warm
