Abstract

Fremgangsmåte for produksjon av kalsiumnitrat ved å behandle kalkstein med salpetersyre, fordampning av kalsiumnitratløsningen, etterfulgt av avkjøling og krystallisering av produktet ved det faste trinnet, særpreget ved det faktum at reaksjonsprosessen mellom salpetersyren og kalksteinen utføres i en reaktor med en pakking, og konsentrasjonen av kalsiumnitratløsningen utføres til krystallkimene fremkommer in situ, deretter avkjøles den oppnådde krystalliseringssuspensjonen mens mikroelementene i gruppen: Cu, Fe, Mn, Zn tilsettes samtidig, som etterfølges av dannelsen og krystalliseringen av sluttproduktet i en fast form av flak. ?? ?? ?? ?? 1
