Coke Oven Turndown Optimization • Allow flexibility for industry turndowns and coal shortages • Safe , efficient, and quick turndown of SCE oven without damage to the oven structure or life while maintaining coke yield and quality • Improve Max turndown on existing plant – Ovens have been turned down greater than 25% – Further tests may show greater turndown possible • Improvements to allow more turndown and potentially turn off existing ovens September 2011 SunCoke Energy 32
Next Generation Environmental Control • Next North American Plant to meet or exceed EPA regulations – Lower SOx – No planned venting – Still lowest in HAP’s/VOC’s since negative pressure • Improved Quench Tower Design – Lower Emissions – Better Reliability – Faster and more efficient quenching • Environmental Controls can be optimized to meet local requirements and needs September 2011 SunCoke Energy 33
