| titleOfInvention | A treatment process for the mother liquor extraction liquid of the purified terephthalic acid oxidation unit |
| abstract | The invention provides a treatment process for the mother liquor extraction liquid of the purified terephthalic acid oxidation unit, which belongs to the field of separation, recovery and reuse of industrial waste. The solid-liquid separation method crystallizes and separates to obtain solid organic matter and separation liquid, and then separates and recovers the beneficial substances in them; or adopts esterification process to react most of the organic matter to form esters and recover them, and the separation liquid generated by washing in the process is recovered and treated ; Or dissolve with a solvent and separate the solids and liquids for recovery, and the washing liquid produced during the washing process is recovered and processed. After the improvement of this process, the economic value of some beneficial substances is recovered; the difficulty and cost of sewage treatment are reduced; the consumption of alkaline substances is reduced, and the cost of enterprises is generally reduced and the utilization rate is increased. |
