GRANULATED CALCIUM CHLORIDE PRODUCTION PROCESS Russian patent published in 2006 - IPC C01F11/24 B01J2/16 

FIELD: inorganic compounds technologies.

SUBSTANCE: granulated calcium chloride is prepared in fluidized-bed vessel, wherein fluidized bed is created by flue gas flow at bed temperature 150-200°C, gas flow velocity in the bed 2.5-3.0 m/s, and hydraulic resistance in bed 500-700 kg/m². Granules are sprayed with 46-50% calcium chloride solution, which was preliminarily concentrated by leaving gas heat and further concentrated by dissolving dust fractions.

EFFECT: achieved uniform granulometric composition, increased strength of granules, and reduced moisture content therein.
