METHOD FOR DEHYDRATING NITRATE HYDRATES

摘要

The invention relates to a method for dehydrating nitrate hydrates, in particular calcium nitrate, which occurs most frequently in the hydrate form thereof Ca (NO3)2 (H2O)4, known as calcium nitrate tetrahydrate. In the method, the nitrate hydrate, which is commercially available in tonnages, is dehydrated in a continuous process by melting the nitrate hydrate and heating the nitrate hydrate in a rotary kiln and can be fed to a device for mixing the heat-transfer medium on a salt basis in a metered manner after being freshly produced, for example also continuously.
