New Approach for Quantification of Perfluorocarbons Resulting from High Voltage Anode Effects

摘要: The methodology used for accounting PFC emissions resulting from aluminum smelting have been developed nearly 20 years ago. There has not any update on this since 2008 and recently published research demonstrated possible avenues improvements in increased accuracy. Current models the industry quantify linearly, based monthly average polarized anode effect duration entire pot lines. To potentially increase precision of quantification process, other approaches, composed non-linear models, were to estimate during individual high voltage effects. Gas monitoring was performed different smelters efficiency these methods evaluated discussed. potential benefits drawbacks related those methodologies by extrapolating results significant operation periods. Additionally, with analysis, it assure time-consistency between original new approaches explored paper.
