Methods of verifying net carbon
- Ravenswood Aluminum, WV (United States)
Problems currently exist with using net carbon as an industrial standard to gauge smelter performance. First, throughout the industry there are a number of different methods used for determining net carbon. Also, until recently there has not been a viable method to cross check or predict change in net carbon. This inherently leads to differences and most likely inaccuracies when comparing performances of different plants using a net carbon number. Ravenswood uses specific methods when calculating the net carbon balance. The R and D Carbon, Ltd. formula developed by Verner Fisher, et al, to predict and cross check net carbon based on baked carbon core analysis has been successfully used. Another method is used, as a cross check, which is based on the raw materials (cokes and pitch) usage as related to the metal produced. The combination of these methods gives a definitive representation of the carbon performance in the reduction cell. This report details the methods Ravenswood Aluminum uses and the information derived from it.
