摘要: 对某功能化学品厂的脂肪醇聚氧乙烯醚生产装置进行模拟。依托反应动力学模型,对该生产装置可能发生的事故过程进行建模与仿真,得到反应釜内事故发生过程的动态数据变化情况,确认正常生产过程中反应釜内最大温度在172 ℃以下,最大压力在3 atm(1 atm=10×105Pa)以内,当环氧乙烷投料速率过快时,釜内温度和压力都会远远高于设计要求的最大值。基于ALOHA软件,开展事故后果的数值模拟定量分析,发现生产过程中发生火灾的热辐射影响范围可以达到150 m,爆炸事故的影响范围接近400 m。

Abstract: The production process of fatty alcohol polyoxyethylene ether in a chemical plant was investigated and simulated. Based on its reaction kinetics model, the possible accidents were modeled and simulated. In the normal production process, the maximum temperature of the reactor is below 172 ℃, and the maximum pressure is under 3 atm(1 atm=10×105Pa). When the feed rate of ethylene oxide is too fast, the temperature and pressure in the reactor will be much higher than the design requirements. Based on the ALOHA software, numerical simulation and quantitative analysis of accident consequences are implemented. During the production process, the impact range of fire heat radiation is about 150 m, and explosion is close to 400 m. Accident consequence analysis can provide guidance for safety production and emergency management of such process.
Key words: fatty alcohol polyoxyethylene ether; production accident; accident simulation
