Abstract

La solution est traitée dans une étape de cristallisation, les cristaux et le sirop-mère sont recristallisés avant la séparation dans une installation de cristallisation à froid sous vide. Le produit liquide écarté provenant d'une séparation ultérieure par centrifugation est envoyé à une installation de dessalement, le produit liquide écarté provenant du dessalement partiel est mélangé au jus à cristalliser et cette solution est, avant l'introduction dans une installation de cristallisation par évaporation sous vide, concentrée en utilisant les vapeurs extraites.
