Deep cooling air separation equipment

The nitrogen from the top of the upper tower is piped through the nitrogen gas pipeline, reheated through the main heat exchanger of the colder tower, and a portion of the nitrogen is pumped out, then combined with the first pipeline and a portion of the nitrogen vaporised in the liquefier in the third pipeline before going to the main vessel. The first raw material air pipeline is heated up and out of the cold box in liquid air separation plant, then goes to the high pressure heat exchanger of ...

Advantages of centrifugal compressors in small air separation unit Gas compression can be divided into volumetric and speed type according to the principle, piston air compressors are commonly used volumetric compressors, while centrifugal compressors are speed type compressors. The advantages of centrifugal compressors compared to piston compressors are obvious: compact structure, small size, large displacement, small consumption of raw materials; less wearing parts than piston compressors, lo...
