Process for the conversion of sodium bromide to anhydrous hydrobromic acid and sodium bisulfate, said process with the following sequential steps: reaction of sodium bromide and sulfuric acid in a solution of water to produce hydrobromic acid and sodium bisulfate wherein the conversion of sodium bromide is greater than about 99%; adsorption of iron bromide onto a solid adsorbent; separation of hydrobromic acid and water from the sodium bisulfate; separation and drying of hydrobromic acid; and solidification of the sodium bisulfate into a flaked or granular form.
Processus de transformation du bromure de sodium en acide hydrobromique anhydre et en bisulfate de sodium, ledit processus comprenant une séquence de stades suivants: réaction du bromure de sodium et de l'acide sulfurique dans une solution aqueuse visant à produire de l'acide hydrobromique et du bisulfate de sodium, le pourcentage de transformation du bromure de sodium étant supérieur à 99 %; adsorption du bromure de fer sur un adsorbant solide; séparation de l'acide hydrobromique et de l'eau du bisulfate de sodium; séparation et séchage de l'acide hydrobromique; et solidification du bisulfate de sodium sous forme de flocons ou de granules.
