Abstract
A method for producing halide brine wherein an alkali and a reducing agent are added to an aqueous fluid having a density greater than 8.30 lb/gal., (0.996 kg/L) water, waste water or sea water for example. The resulting fluid is then contacted with a halogen to form a halide brine. The reaction occurs in a conventional reactor such as a mixing tank.
