Primary aluminum reduction is energy and emissions intensive. It is very important for the environment and for business to treat potline fume efficiently. This article discusses how to improve potline fume efficiency from several respects based on CHALIECO GAMI’s experimental studies which were applied successfully in many modern potline’s Fume Treatment Plants (FTP), and also demonstrates the significance of improving alumina injection feeding and flow field inside the bag filter. A new and efficient method for the filter pulse control system is introduced, which is used in Vedanta’s recent Jharsuguda project in India.Based on these studies and applications, as well as new development of pulsing control system, CHALIECO GAMI is now able to control the HF emission concentration and the dust emission concentration respectively below 0.8mg/Nm3 and 5mg/Nm3 at the stack outlet of the FTP.
