摘要:
随着本质安全研究的深入,道化学评价方法中物质系数MF的计算已不能准确描述反应物本身的热风险大小。在道化学评价方法中引入热风险概念,比较热危险性评价方法和道化学评价方法间相异点;以六甲基磷酰三胺工艺为研究对象,用DSC量热仪对反应物进行分析得出放热速率q、反应波峰峰值、单位质量的反应焓Hr,对采集的工艺参数用热力学理论外推法、基因贡献法得出活化能E、比热容CP并以此求出最大反应失效时间TMRad、绝热温升Qad、物质系数MF值以及工艺单元中物料量。得出最大反应失效时间与物质系数MF间具有相关性,道化学评价方法对因失效反应引发二次反应的热风险评估也适用。
Abstract:
With the development of safety research, material factor(MF value)of Dow chemical evaluation method can not accurately describe the size of thermal risk. The difference between thermal hazard evaluation method and Dow chemical evaluation method was analyzed by introducing thermal rick concept in Dow chemical evalution. DSC calorimeter was used to applysis the reactant so as to obtain heat release rate q, reaction wave peak and reaction enthalpy Hr. The thermodynamic theory extrapolation and group contribution method were applied to analyze the measurred process parameters, activation energy E and specific heat capacity CP were obtained, then the maximum response time to failure TMRad, adiabatic temperature rise Qad, material factor MF and the amount of material in the process unit were found out. It showed that the maximum response time to failure is related with MF, and Dow chemical evaluation method is useful for thermal risk assessment with secondary reaction caused by failure reaction.
