Abstract
Approximately 95% of the SO2 emissions generated by a smelter can be attributed to sulfur found in the incoming petroleum coke used in anode production. Efforts to reduce smelter SO2 emissions and increasingly demanding environmental permit requirements have resulted in a number of plants shifting to lower sulfur coke. Lower sulfur concentrations in the anode have been demonstrated by others to negatively impact anode quality and potentially Potroom performance by increasing the anode carboxy reactivity. In the following paper, we explore various methods to minimize this impact. These include, types of low sulfur cokes to be used in the coke blend, alterations in aggregate granulometry, and improved baking practices. The results from these studies are presented.
