Liquid layer on sieve plate

The molecular sieve on the air separation is currently used more 13X-APG type molecular sieve. The process principle is to use the internal porosity of its particles, and has a strong affinity for polar molecules, selective adsorption of carbon dioxide, water, and some hydrocarbons and other impurities. Activated alumina has high compressive strength, low abrasion rate, no pulverization, no bursting, etc. Its resistance to sudden changes in cold and heat is also very strong, and it also has bett...

  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...
