Abstract

The invention relates to chemical technology pertaining to mineral salts and can be used in the chemical industry. A process for producing ammonium bromide from a bromide-containing polycomponent hydromineral feedstock includes: two-stage oxidation of bromide ions using gaseous chlorine during acidification of a brine; air desorption of elementary bromide; absorption of same using a cooled solution of ammonium bromide; and reduction using an ammonia solution. The resulting concentrate of ammonium bromide is evaporated until crystals are formed. The ammonium bromide crystals are dried and the mother liquor is used to produce a solution of ammonium bromide as a commercial product.

Abstract

The invention relates to chemical technology pertaining to mineral salts and can be used in the chemical industry. A process for producing sodium bromide from a bromide-containing polycomponent hydromineral feedstock includes: two-stage oxidation of bromide ions using gaseous chlorine during acidification of a brine; air desorption of elementary bromide; absorption of same using a cooled solution of sodium bromide; and reduction using ammonia in the presence of sodium hydroxide. The resulting concentrate of sodium bromide is evaporated until crystals are formed. The sodium bromide crystals are dried and a mother liquor is used to produce a solution of sodium bromide as a commercial product.
