【 摘 要 】

The sources of formation of sulfur dioxide during the production of anodic mass (baked anodes) and aluminum by electrolysis are analyzed; the method for calculation of the formed sulfur dioxide anhydride depending on the quality of the used raw materials is presented. Total emissions of sulfur dioxide are estimated for different methods of anode mass production, electrolysis cell structures and methods for purifying waste gases.
