中文摘要:
      本文采用微通道反萃取模型装置,以P507-煤油体系中铒离子为研究对象,系统考察了微通道反应器尺寸、盐酸浓度、进料流速和有机相中铒离子预负载量等因素对反萃取过程的影响。结果表明,当微通道直径为0.6mm,长度为200cm, 停留时间为8.48s时,有机相中稀土Er3+的反萃率可达88.41%;盐酸浓度为6mol/L时反萃取率最高。与传统萃取方式相比,微通道反萃取具有较高的反萃取效率,总传质系数为传统萃取方式的8-10倍。
Study on enhancing striping loaded Erbium in organic phaseby Y-type microchannel reactor

英文摘要:
      In this work, a novel method for stripping Erbium from the pre-loaded P507-kerosene organic solution by a Y-type microchannel reactor was investigated. The effects from the microchannel size (length and diameter), the concentration of HCI, the flow rate and the concentration of loaded Erbium in organic phase on the Erbium stripping performance were focused on. The results showed that when the diameter of the microchannel and its length were 0.6 mm and 200 cm respectively, and the residence time of the organic phase in the microchannel reactor was 33.91s, and the concentration of HCI was 6 mol/L, the percent stripping of Erbium from the pre-loaded organic phase could reach 88.41%. Compared to the traditional mixer-settler extractor, the microchannel reactor exhibits a higher striping percentage under the same conditions, and the total mass transfer coefficient is 2 to 3 times than that of the traditional extraction methods.
