titleOfInvention | Process and apparatus for the production of calcium bromide by liquid-liquid extraction |
abstract | A process for the production of calcium bromide from feed brines, particularly from Dead Sea End Brine (EB), is described. The process comprises extracting the feed brine in countercurrent with a composite organic solvent; optionally, purifying the extract to increase the ratio Br:Cl by contacting it with a part of the product; and washing the purified extract with water to yield the product, that is an aqueous solution of CaBr2. The composite solvent comprises an anionic extractant, such as an amine or a mixture of amines; a cationic extractant, such as a carboxylic phosphoric or sulphonic acid or a mixtures of said acids; and diluent/modifier, which is an organic solvent. An apparatus for the production of calcium bromide is also described, which comprises: an extraction battery; optionally, a purification battery; and a washing battery, wherein at least one of the batteries comprises a plurality of stages. |
