Lime Slurry an overview ScienceDirect Topics

Arthur L. Kohl, Richard B. Nielsen, in Gas Purification (Fifth Edition), 1997. Process Description. The overall effects of the double alkali process are identical to those of the limestone/ lime slurry processes—SO 2 is removed from the gas, lime or limestone is consumed, and a calcium sulfite or sulfate by-product is produced. The intermediate steps, however, are quite different and result
