In view of the characteristics of industrial gases used in nonferrous smelting industry, my company on the matching air distribution device using a pressure in the end and set up an air booster two internal compression process for analysis and comparison, to 16,000nm3/h scale air distribution as an example in the operation of energy consumption, project investment, operational and other aspects of the comparison, The paper points out that the process scheme has advantages in project investment, operation and so on, and the energy consumption is lower when the flow scheme of Air supercharger is set up.
