<p>A method and an apparatus for recovering bromine from a liquid effluent by high-temperature pressurised combustion of the liquid effluent in a combustion chamber (10), maturation of the flue gases at medium temperature in a chamber (20), hetero-azeotropic distillation of the gases in a distillation column (26) such that the gaseous water/bromine mixture produced by distillation is condensed (at 36, 38), and separation of the bromine in a settling tank by demixing the water and bromine at a temperature of around 5 °C, the resulting liquid bromine being distilled again in a column (48) and thereby purified to 99.9 %.</p> |
