A process includes supplying a bromide brine and removing organic compounds from the bromide brine. The method also includes acidifying the bromide brine to form a stream containing hydrobromic acid and separating the hydrobromic acid from the stream containing hydrobromic acid.

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.

Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated using a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.

A process produces salt by way of strong brine concentration after sea water desalination by using a two-way circulation method and bromine extraction. The process includes the following steps: A, preparing fresh water and strong brine from sea water in a high-pressure reverse osmosis unit by using a reverse osmosis method, wherein the concentration of the prepared strong brine is 70000 to 80000 PPM; and B, performing fresh and concentrated separation on the strong brine with the concentration of 70000 to 80000 PPM in a two-way circulation manner by using a concentration difference method till the strong brine is crystallized.
