  • Sulfur Dioxide Scrubber: pH Control | Yokogawa India

    The scrubbing liquor can be bubbled through a slurry or either lime, Ca(OH) 2, or limestone, CaCO 3 and water. Either lime or limestone will combine with the sulfite ions from the flue gas to form gypsum, CaSO 3. The SO 2 that is captured in a scrubber combines with the lime or limestone to form a number of byproducts. A primary byproduct is ...
