Method for preparing calcium carbonate for scrubbing sulfur oxides from combustion effluents |
摘要 |
Limestone is dried for grinding to very fine particles e.g., about 8 mu or less with more than 99% of the particle by weight less than 44 mu , by utilizing waste heat from the flue gas from a large combustor. The finely-divided calcium carbonate is then introduced dry into a scrubbing tower where it mixes with and renews the slurry employed therein for scrubbing SOx-laden effluent.
