| titleOfInvention | Process for recovering bromine from mother liquor extract of oxidation process of terephthalic acid production device |
| abstract | The invention provides a process for recovering bromine from mother liquor extract of an oxidation process of a terephthalic acid production device, belonging to the field of process recovery. The mother liquor extract of the oxidation process of the terephthalic acid production device mainly contains acetic acid according to the material content, namely the acetic acid is used as a solvent, cobalt ions, manganese ions, bromide ions, BA, sodium ions, iron ions, 4-CBA, PT acid and the like with relatively low concentration are dissolved, and bromine in the mother liquor extract is extracted by the method to obtain hydrobromic acid or sodium bromide for recycling, so that the economic value of the bromine is recovered; meanwhile, the problem that bromine in the part is discharged into sewage in the prior art and can cause adverse effects on biological flora of a sewage treatment unit and influence on the activity of the biological flora is avoided. |
