Future prospects of cryogenic air separation technology

  After the gas flows out of the expander impeller, there is still a certain speed. This part of mechanical energy without work is called residual speed loss. In order to reduce the velocity of the gas flow at the outlet of the expander, there is generally a section of expanding short pipe at the outlet of the expander impeller. This section of short pipe can reduce the velocity of the air flowing out of the expander impeller, reduce the...

The principle and characteristics of large air separation cryogenic nitrogen production Nitrogen is the main component of air, accounting for about 78% of air. With the progress of science and technology and economic development, the application of nitrogen is expanding and has penetrated into many industrial sectors and daily life. There are several main methods of producing nitrogen. One of them is cryogenic air separation nitrogen, which is a traditional method of nitrogen production and ha...
