介绍了黎明化工研究设计院有限责任公司研发的含重芳烃–磷酸三辛酯–四丁基脲(AR+TOP+TBU)三元溶剂工作液在过氧化氢工业生产装置中的应用情况。采用上述新技术对5万t/a的过氧化氢生产装置进行扩产改造,装置产能提高至7万t/a,氢效≥9.0 g/L,平均氧化收率≥96.9%,平均萃取液w(H_2O_2)≥35.0%,平均萃余液ρ(H_2O_2)≤0.13 g/L,产品w(总有机碳)≤130×10~(–6),平均日产量≥220 t,改造后的装置已连续稳定运行23个月以上。
The application of AR + TOP + TBU containing heavy aromatic hydrocarbon - trioctyl phosphate - tetrabutyl urea (AR + TOP + TBU) working solution developed by Liming Institute of Chemical Industry Research and Design Institute Limited Company in the hydrogen peroxide production plant was introduced. The above new technology was used to expand and reform the 50,000 t / a hydrogen peroxide production plant, the unit production capacity was increased to 70,000 t / a, the hydrogen efficiency was greater than or equal to 9.0 g / L and the average oxidation yield was ≥96.9% w (H_2O_2) ≥35.0%, average raffinate ρ (H_2O_2) ≤0.13 g / L, product w (total organic carbon) ≤130 × 10 -6, average daily output ≥220 t, Has been stable and continuous operation for more than 23 months.
