  • Process Compatible SO2 Control In Cement Kilns

    The Chemistry and Flow of Sulfur in a Cement Kiln. The counter flow of raw materials and exhaust gases in the raw mill and preheater act as an inherent semi-dry (raw mill) and dry scrubber (preheater) to control SO 2 emissions. Some SO 2 may also be dry scrubbed in the baghouse particulate control system.
