摘要: 通过采用MSMPR反应沉淀器,研究了普鲁卡因青霉素反应沉淀过程中粒子的聚结和破裂对过程的影响机理,并对用生死函数表征聚结和破裂的粒数衡算模型采用新的分析方法。结果表明,将二元破裂模型应用于该粒数衡算模型是可行的。

Abstract: The breakage model including two - body equal - volume birth function and two - body powerlaw death function was used in the agglomeration and breakage population balance model . The new analysis method made the population balance model fit crystal size distribution very well . The results of crystallization kinetic experiment by using MSMPR precipitator has proved that the new method is correct. So a reasonable method of study on agglomeration and breakage of reactive precipitation of procaine ben-zylpenicillium can be obtained .
