METHOD OF PRODUCING GRANULAR CALCIUM CHLORIDE Russian patent published in 2012 - IPC B01J2/16

Abstract RU 2460579 C2

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering for producing calcium chloride in granular form. Granular calcium chloride is obtained in a fluidised bed apparatus, said fluidised bed being formed by a stream of furnace gases and having temperature 150-200°C, flow rate of gases in the layer of 2.5-3 m/s, hydraulic resistance of the fluidised bed of 500-700 kg/m², further evaporation of the solution and sputtering thereof onto granules with concentration 50-55% and temperature 115-130°C.

EFFECT: invention enables to obtain granular calcium chloride with high apparent density and increases efficiency of the drier and the fluidised bed.
