Latest Patents
Gijsbertus H Calis holds a patent for a process that separates calcium nitrate tetrahydrate from a nitrophosphate digestion liquor through crystallization. The patent details a method where Ca(NO.sub.3).sub.2.4H.sub.2 O seeding material with a particle size smaller than 100 µm is added to the liquor at a temperature slightly below the saturation temperature. This process allows for the batchwise cooling of the liquor, resulting in the crystallization of Ca(NO.sub.3).sub.2.4H.sub.2 O, which can be easily separated from the cooled liquor. The method ensures that the calcium nitrate crystallizes out as very coarse and uniform particles without excessive cooling.
