Abstract

"PROCESSO PARA A PRODUçãO DE CRISTAIS DE CLORETO DE SóDIO A PARTIR DE UMA SALMOURA DE CLORETO DE SóDIO CONTAMINADA POR CLORETO DE POTáSSIO E IONS SULFATO" Processo para a produção de cristais de cloreto de sódio partindo de uma salmoura de cloreto de sódio contaminada por cloreto de potássio e íons sulfato, em que se adiciona um composto de cálcio (32) à salmoura (48) para cristalizar glauberita (35) que se colocada de lado, submete-se a solução aquosa resultante (36) a uma evaporação para cristalizar cloreto de sódio (40), que se recolhe e se submete a água mãe (41) da cristalização do cloreto de sódio a um resfriamento (42) para cristalizar a glaserita (45).
