摘要： The invention relates to an evaporative crystallisation process to make salt compositions which includes a step wherein a mother liquor containing an effective amount of a crystal growth comprising at least one saccharide or saccharide derivative is formed, to form high-purity salt. The salt can be washed with a reduced amount of washing water while still containing lower amounts of K, Br, SO4 and/or Ca. The high-purity salt can be obtained after drying of the salt crystals formed. A wet salt can be obtained by partially drying said salt crystals.

摘要： The invention pertains to a method for at least partially removing soluble divalent anions from an aqueous divalent anion-containing brine solution comprising a crystal growth inhibitor (CGI) for the divalent anion, the method comprising the process steps: obtaining a sodium chloride concentration between 100 g/L and saturation in the presence or absence of a CGI for sodium chloride or a sodium chloride concentration above saturation in the presence of a CGI for sodium chloride, and acidifying the solution to a pH below 11.5; subjecting the solution to a membrane filtration step thereby separating the brine solution into a brine stream being supersaturated for the divalent anion (concentrate), and a brine stream being undersaturated for the divalent anion (permeate); subjecting the supersaturated brine stream comprising the crystal growth inhibitor for the divalent anion to a crystallization process, removing crystallized divalent anion; and optionally, recycling the overflow of the crystallizer to the brine solution for subjecting it again to the membrane filtration step.
