| Abstract Scope |
In the 1990s the global warming potential (radiative forcing) of atmospheric perfluorocarbon (PFC) led to an increase of public concern about the effects of their accumulation in the Earth’s atmosphere. At that time PFCs were only considered to occur during anode effects in the aluminum industry. In recent years, PFC emissions have also been found to occur during normal operation periods, specifically below the computer anode effect detection voltage and particularly in modern high amperage cells, thereby negatively impacting the development of accurate global PFC inventories. The most recent break-through in understanding has been the rediscovery of “co-evolution” of perfluorocarbon gases and carbon oxide gases during both normal operation and anode effects. Work is underway currently to develop strategies to stop unaccounted PFC emissions from occurring in industrial aluminum cells and to include their emission with the total amounts reported. |
