METHOD OF PRODUCING NON-CAKING AMMONIUM NITRATE Russian patent published in 2013 - IPC C05C1/00

Abstract RU 2491261 C1

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. The method of producing non-caking ammonium nitrate, which involves adding a magnesia additive obtained by decomposing magnesium-containing material with nitric acid to molten ammonium nitrate, followed by neutralisation of the mixture with ammonia, evaporation and granulation, wherein sludge from ultra-filtration equipment for production of desalinated water is added to the melt along with the magnesia additive in amount of 0.04-0.4 kg/t ammonium nitrate.

EFFECT: invention enables to obtain a product of high quality.
