Techniques for Determining Limestone Composition and ...

Limestone quality affects sulfur dioxide (SO) removal, reaction tank sizing, limestone consumption rate, and composition of the gypsum product and waste streams. Reactivity is a direct measure of how readily a limestone will provide alkalinity to neutralize the acid resulting from SO dissolution in water.
