Daniel Crowley of Titan America Medley Florida presented a paper titled “Cement Kiln Mercury Reduction Strategies A Case Study in Materials Management” at the 2010 IEEE Cement Industry Conference. He provided insight into Titan’s experience with Hg monitoring and control strategies. Titan’s experience indicates that to meet EPA proposed limits using continuous dust wasting they would have to waste 10% of all feed produced. By wasting dust only with the raw mill off (and after Hg levels had peaked) Titan found that they could achieve a 43% reduction in Hg levels; concluding that dust wasting will probably not be a practical means to meet EPA proposed Hg limits. |
