Solubilities in seawater-type systems: Some technical and environmental friendly applications

Abstract

The crystallization sequence of salts during solar evaporation of seawater and brines is discussed. The supersaturation phenomena in highly concentrated seawater-type systems, which influence the crystallization sequence, are explained by differences between the Mg2+-complexes in the solutions and in the solid phases. Methods to increase the yield of the solar sea salt production, to improve the salt quality and to utilize the waste brines, by using knowledge on the solubility diagrams, are developed. An environmental friendly multiproduct method is suggested for magnesium hydroxide and sea salt production. © 1993 IUPAC
