Abstract Scope |
Perfluorocarbons (PFC) emissions must be reported as accurately as possible. The aluminum industry is using consistent method to estimate high voltage PFC emissions. However, a new or improved method is needed to account for low voltage PFC emissions. Thus, equipment and time frequency must be revised to estimate both high and low voltage emissions during not only anode effects above 8 volts but also during pot disturbances that affect pot noise and therefore can make the contribution of low voltage emissions significant higher. Preliminary results showing the variability of low voltage and estimation of total PFC emissions is presented from recent PFC measurement campaigns at Alcoa smelters. |
