Impurity Enrichment Mechanism and Selective Removal Technology of Chlorine Recycle System in Chlorination-Oxidation Coupling Process
氯化-氧化耦合工艺是有色金属冶金与精细化工领域的核心技术,氯循环系统内多杂质协同富集易引发设备腐蚀、反应效率衰减等问题.本文研究明确了系统核心杂质为Fe3+、Ca2+、SO42-及氯代苯,揭示了溶解-浓缩、吸附-解吸、化学反应滞留的协同富集机制,建立了高精度杂质预测模型并提出工况调控策略.在此基础上,筛选得到氨基膦酸型螯合树脂为最优脱除剂,开发适配现有工业设备的固定床吸附工艺及一体化再生方案,研究结果可为氯化-氧化耦合工艺氯循环系统的稳定高效运行提供技术支撑.
The chlorination-oxidation coupling process is a core technology in the fields of non-ferrous metal metallurgy and fine chemicals.The co-enrichment of multiple impurities in the chlorine circulation system can easily cause various problems.This paper clarifies that the core impurities in the system are Fe3+,Ca2+,SO42-and chlorobenzene,establishes a high-precision impurity prediction model and proposes operation condition control strategies.On this basis,amino phosphonic acid type chelating resin is selected as the optimal removal agent,and a fixed-bed adsorption process and an integrated regeneration scheme suitable for existing industrial equipment are developed.The research results can provide technical support for the stable and efficient operation of the chlorine circulation system in the chlorination-oxidation coupling process.
