摘 要: 为在过程早期获取本质安全性较好的反应路径,将模糊安全评价集成于反应路径综合形成有效方法。根据反应路径综合阶段信息选择指标,通过设定指标的隶属度函数,建立模糊推理系统,且应用层次分析法(analytic hierarchy process,AHP)求得指标的权重因子,形成了模糊评价方法。为消除中间变量的影响,分别建立单、双输入变量的模糊推理系统。将它集成于反应路径综合,通过原料筛选规则,模糊安全评价,建立以安全为目标的优化模型,求解得到优良的反应路径组合。应用于萘甲胺反应路径综合实例,定量得到了反应路径及其目标函数值,并对两种模糊系统的综合结果进行了比较。 Aimed to obtain inherently safer chemical reaction path during early phase of chemical process, fuzzy safety assessment is integrated to reaction path synthesis to provide effective method. Indices are selected based on process information in the reaction path synthesis phase. Through setting membership function of each index, establishing fuzzy inference system, and determining the weighting vector by AHP, the fuzzy assessment method is proposed. To eliminate the impact of medium variable, the fuzzy inference system of single input variable and double input variables are provided respectively. Integrating the method to reaction path synthesis, the benign reaction path will be obtained through material screening rules, fuzzy safety assessment, and opzimization treating safety as objective function. By analyzing the application of reaction path synthesis for carbaryl production, reaction paths with their objective function value is obtained. The results for two kinds of fuzzy system are compared finally.
