  • Removal of bromine from gaseous hydrogen bromide
    Patent number: 9475697
    Abstract: Processes of and systems for removing free bromine from gaseous anhydrous HBr contaminated with free bromine are described. In one type of process the gaseous contaminated HBr is fed into countercurrent contact with at least one liquid alkylaromatic hydrocarbon within a packed section of a column while maintaining the packed section under free radical bromination conditions so that one or more than one liquid a-bromoalkylaromatic compound is produced along with one mole of gaseous HBr per mole of a-bromoalkylaromatic compound produced. In another type of process the gaseous anhydrous HBr is fed into countercurrent contact through at least two scrubbers so that the gaseous anhydrous HBr is scrubbed substantially free of bromine by passage through these at least two scrubbers, each of which contains a different specified type of scrubbing liquid. In one embodiment the liquid alkylaromatic hydrocarbon comprises 1,2-diphenylethane.
