摘要
主要通过建立分配比模型、化学反应模型、传质模型构建了一套基于混合澄清槽的PUREX流程中关键循环过程的计算模型(mathematical model for main PUREX process based on mixer-settler,简称MPMS),用于计算各级单元的物料浓度。通过检验两组具有代表性的PUREX工艺流程,模拟结果较好地匹配实验数据,表明该计算模型具有良好的精确性。该计算模型将为基于多级混合澄清槽的PUREX流程模拟提供有益帮助。
In this paper,a set of mathematical model for main PUREX process based on mixer-settler(MPMS)is constructed by establishing distribution ratio model,chemical reaction model with specific algorithm,and mass transfer model,using for calculating substances'concentration of each stage of mixer-settler.By comparing the simulation results and experiment results of two representative PUREX process,it indicates that there is good accuracy of our mathematical model.MPMS will be useful for PUREX process simulation based on multi-stage mixer-settler.
