摘要

在总结分析前人成果的基础上，利用生产现场采集的转化率与平均分子量的人工分析值，基于概率统计原理提出了丙烯腈连续水相聚合过程中聚合体微团转化速率的Cauchy分布，并由此用宏观混合法导出了由总转化率和平均分子量的表达式组成的动力学模型.在该模型中，还通过神经网络子模型、回归子模型等建立了现场操作条件同模型中间参数k1、k2和k3间的定量关系.仿真和生产现场运行结果都证明该模型能较好地反映实际过程特性，具有较好的效果.

Abstract

Based on predecessors’work

and the plant data of total conversion rate and number-averaged molecular mass

the Cauchy distribution of micro cores is proposed in terms of the principle of probability and statistics. The macro kinetic model with expressions of the total conversion rate and number-average molecule mass is derived from the macro mixed method. Additionally

the neural network sub-model and the regression sub-model are used in the model for building up the correlation functions of intermediate parameters k1

and k3 with the operation conditions. It is verified by the simulation and practical running results that the model can present practical process properties.
