ABSTRACT:
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.
