Bromine being a highly reactive material, Finds wide applications in many chemical industries like, Organic intermediates, Dye stuffs, Agrochemical, Fire retardants etc. Bromine can be recovered from : - Industrial bromides (NaBr, KBr, HBr) - Bittern Aqueous bromide solution is reacted with chlorine vapour in reaction column. The chlorine liberates elemental bromine from the dissolved bromide. This is stripped out by live steam feed from the bottom of column. Crude bromine is then distilled to get bromine purity of minimum 99.5%. The solution is not so simple though, as feeds are often contaminated with organic material from process. these organic impurities have to be removed by pre-treatment before feeding to the plant. Typical plant consists of stripping column, Heat exchangers phase separator, Purification column collection pot, Re-boiler, Scrubber with associated glass piping with fittings. All wafted components are made from borosilicate glass and PTFE which are corrosion resistant even at elevated temperature. |
