The report describes a reliable experimental method that can be used routinely to determine the crystal size distribution function, a measure that is required for a mathematical representation of the nucleation and growth processes involved in the settling, dewatering, and disposal of calcium sulfite sludge from lime/limestone or dual alkali scrubbers, a major problem associated with coal burning. Optical and instrumental crystal sizing methods were compared and the merits of each discussed; Coulter counting is recommended.
