Study of Perfluorocarbon Release During Aluminum Production in Vertical-Stud Electrolytic Cells with Self-Baking Anode in Between Anode Effects

详细

Emissions of perfluorocarbons (PFCs) from the vertical-stud Soderberg cells during aluminum production outside of anode effects were studied. PFC emissions were monitored at the flue gas pipe coming from 22 cells provided with automated alumina feeding system. In the process of measurements, no significant PFC emissions were detected. Based on the results of the analysis, it was concluded that only PFC emissions from the Soderberg cells produced during anode effects should be monitored without accounting for PFC emissions formed outside of anode effects.
