METHOD OF PRODUCTION OF GRANULATED ALUMINUM SULFATE Russian patent published in 2000 - IPC

FIELD: production of granulated aluminum sulfate. SUBSTANCE: melt of aluminum sulfate is passed through perforated vibration partition into hydrophobic liquid for forming spherical particles at weight ratio of granulated aluminum sulfate to hydrophobic liquid between 1:1 and 1:3; temperature of hydrophobic liquid is maintained from 10 to 20 C; time of keeping the granules in hydrophobic liquid ranges from 10 to 30 min; then hydrophobic liquid is separated from granules thus formed. Melt of aluminum sulfate is passed through perforated vibration partition having diameter of perforations of 0.5 to 0.8 mm; temperature of melt is maintained at 100 to 115 C. Separation of hydrophobic liquid and granules is effected in centrifuge at separation factor of 300 to 1000 and temperature of 25 to 45 C. EFFECT: low cost of process; improved quality of product. 3 cl, 1 tbl
