Abstract:
The invention relates to a process for recovering bromide from a halide-containing aqueous stream, comprising the steps of: providing a feed of halide-containing aqueous stream; contacting an anion-exchange resin with said feed, to form halide-loaded resin; treating said halide-loaded resin with a regenerant and subsequently with a rinse to produce, in succession, a chloride-rich solution, a mixed chloride/bromide solution, a bromide-rich solution and an essentially halide-free solution; directing said mixed chloride/bromide solution to said feed; processing said bromide-rich solution to recover one or more bromide products; and utilizing said essentially halide-free solution for regenerant dilution and/or rinsing of said resin. An apparatus for carrying out the process is also disclosed.
