Since 2002, an increasing gap between the declared quantity of perfluorocarbons (PFC) generated by human activities and the atmospheric measurements has been observed; forcing the industry to re-examine the quantification methodology to find the root cause of this inconsistency.
Current methodologies used in the aluminum industry quantify PFC emissions linearly, based on the monthly average polarized anode effect duration for entire pot lines. To potentially increase the precision of this methodology, other approaches, including non-linear models, were used to estimate the emissions of PFC for shorter periods (weekly, daily, and individually). Gas monitoring was performed in different smelters and the efficiency of these methods was evaluated and discussed.
The potential benefits and inconvenience related to those quantification methodologies were evaluated by extrapolating results for significant operation periods. Additionally, with this analysis, it was possible to assure time-consistency between the original quantification methodology and the new approaches explored in this paper.
