Low voltage anode effects (LVAE) have been observed in numerous smelters since early 2010s. Such events are now known to generate perfluorocarbons (PFC) emissions over time and no methodology currently exists to adequately quantify such emissions.
A novel methodology has been developed to quantify the annual LVAE emissions for smelters based on measurement data from multiple in-situ gas measurement campaigns by Marks & Nunez. However, there is currently no estimate of the contribution of those emissions from previous years. This paper investigates the potential effects of adopting this approach and applying it to historic emissions inventories of PFCs.
Based on historical data supplied by aluminium smelters, the total respective PFC emissions resulting from high and low voltage anode effects were calculated using Tier 2 methodologies, allowing evaluation of the impact of LVAE on the total amount of PFC reported. Time-consistency challenges arising from this new approach are explored and discussed.
