§ 98.63 Calculating GHG emissions.

(a) The annual value of each PFC compound (CF4, C2F6) shall be estimated from the sum of monthly values using Equation F–1 of this section:

Where:

EPFC = Annual emissions of each PFC compound from aluminum production (metric tons PFC). Em = Emissions of the individual PFC compound from aluminum production for the month “m” (metric tons PFC).

(b) Use Equation F–2 of this section to estimate CF4 emissions from anode effect duration or Equation F–3 of this section to estimate CF4 emissions from overvoltage, and use Equation F–4 of this section to estimate C2F6 emissions from anode effects from each prebake and Søderberg electrolysis cell.

Where:

ECF4 = Monthly CF4 emissions from aluminum production (metric tons CF4). SCF4 = The slope coefficient ((kg CF4/metric ton Al)/(AE-Mins/cell-day)). AEM = The anode effect minutes per cell-day (AE-Mins/cell-day). MP = Metal production (metric tons Al), where AEM and MP are calculated monthly.

Where:

ECF4 = Monthly CF4 emissions from aluminum production (metric tons CF4). EFCF4 = The overvoltage emission factor (kg CF4/metric ton Al). MP = Metal production (metric tons Al), where MP is calculated monthly.
