反应量热(RC1)数据在泄放计算中的应用

Application Method of RC1 Data in Release Calculation

反应量热仪(RC1)是用来测量一个化学反应释放或者吸收的热量,用于化学反应热效应的评价,为反应的安全运行提供数据支持。反应换热面积的计算、反应传热媒介种类的选择、冷/热媒消耗量的计算、反应时间的计算、泄放量的计算等都会用到反应量热(RC1)数据。在实际使用过程中小试检测时关键物料的加入速率与大生产时关键物料的加入速率并不一样;相同的反应在由不同人员检测时其关键物料的加入速率也会有所差别,其所获得的检测结果也会有差别;因此如何正确的将反应量热(RC1)数据用于工程计算对工程设计人员来说是一项不小的挑战。本文主要介绍反应量热(RC1)数据在反应过度型泄放计算中的使用方法并列举了计算案例。

The Reaction Calorimeter is used to measure the heat released or absorbed by a chemical reaction,assessing the thermal effects of the reaction and providing data support for the safe operation of the process.It plays a crucial role in the calculation of reaction heat exchange area,selection of heat transfer media types,computation of cooling/heating media consumption,reaction time estimation,and calculation of release amounts.In practice,the rate of key material addition during pilot tests differs from that during full-scale production;different operators may add key materials at varying rates,leading to discrepancies in test results.Therefore,correctly applying RC1 data in engineering calculations presents a significant challenge for design engineers.This article primarily explores the use of RC1 data in the calculation of reaction runaway discharges,including calculation cases.
