A computer program named MIXEX2 is developed based on the steady state approach model in order to simulate the performance of multi stages contactor. Experiments are carried out to estimate the efficiency in the partition of U/Pu with N,N dimethylhydroxylamine (DMHAN) as reductant and the reliability of MIXEX2. The results show that Pu and U can be separated effectively under the designed condition with separation factors of SF Pu/U and SF U/Pu both over 10 4. Meanwhile, the calculated...

A computer program named MIXEX2 is developed based on the steady state approach model in order to simulate the performance of multi stages contactor. Experiments are carried out to estimate the efficiency in the partition of U/Pu with N,N dimethylhydroxylamine (DMHAN) as reductant and the reliability of MIXEX2. The results show that Pu and U can be separated effectively under the designed condition with separation factors of SF Pu/U and SF U/Pu both over 10 4. Meanwhile, the calculated concentration profiles of HNO 3, U and Pu are in good agreement with their experimental concentration profiles. Therefore it can be said safely that the program can predict the working performance of extraction contactor successfully.

The mass transfer characteristics of two systems, waterphenol30% TBP (in kerosene) and waternitric acid30% TBP (in kerosene), were studied using an extraction contactor with a microporous polypropylene hollow fiber module which has a very large surface area. The operation process was proposed according to the difference of two phase impregnation to membrane material. The results showed that the membrane module worked well for two (a/o) phase volume flow rates ratio of 0.5~11.0. The mass transfer...

The mass transfer characteristics of two systems, waterphenol30% TBP (in kerosene) and waternitric acid30% TBP (in kerosene), were studied using an extraction contactor with a microporous polypropylene hollow fiber module which has a very large surface area. The operation process was proposed according to the difference of two phase impregnation to membrane material. The results showed that the membrane module worked well for two (a/o) phase volume flow rates ratio of 0.5~11.0. The mass transfer coefficient increased with increasing phase flow rates and the module length had little influence on the mass transfer coefficient but moderately influenced the mass transfer efficiency. The stage efficiency for phenol extraction was close to 100%.

根据液液萃取中两相表面张力以及对膜材料浸润性的不同,选用聚丙烯中空纤维膜器为接触器,设计了新型纤维膜萃取器。这种萃取器具有比表面积大,易于液液两相分离澄清的特点。以水苯酚30%TBP(煤油)和水硝酸30%TBP(煤油)为实验体系,采用两相并流非分散性接触方式,研究了两相流量及膜器长度对纤维膜萃取器传质特性的影响。实验结果表明,纤维膜萃取器可在较宽的水相与油相的体积流量比范围内(0.5~11.0)正常操作;传质系数随两相流量的增加而增大;膜器长度对萃取器的传质系数影响较小,但对级效率的影响较大;对于苯酚体系,级效率接近100%。
