Um sowohl eine konzentrierte, möglichst wenig gelöstes Salz enthaltende Natronlauge als auch ein Festsalz mit möglichst geringem Gehalt an NaOH zu erhalten, werden die beim Eindampfen und Abkühlen der Natronlauge aus der NaCl-Elektrolyse anfallenden Mehrfachsalze zersetzt. Dazu wird im Seitenstrom zum Lauge-Hauptstrom der Eindamp fanlage der entnommene Salzbrei zunächst eingedickt, und ein Teil der Natronlauge mit großem NaOH-Gehalt wird durch Lauge mit geringerem NaOH-Gehalt ersetzt. Die Mehrfachsalze werden in einem ebenfalls im Seitenstrom liegenden Zersetzer mittels Natronlauge mit weniger als 30 % NaOH-Gehalt zersetzt. Bei diesem Verfahren wird weder bereits auskristallisiertes Salz aufgelöst noch die Salzbela stung im Haupt-Laugestrom erhöht. Der Verlust an NaOH wird gegenüber den bisher üblichen Verfahren merklich herabgesetzt | ||||||
