摘要/Abstract

摘要： 液化烃属于甲A类火灾危险液体，一旦发生泄漏，遇点火源会产生严重后果。为了有效预防液化烃储罐气体泄漏，以某石化液化烃罐区为例，采用FLACS软件模拟液化烃泄漏及可燃蒸气气云溢散分布，通过分析蒸气云扩散规律对现有可燃气体探测器布置方案进行评估，并提出优化方案。结果表明，原有布置方案下可燃气体探测器覆盖率为46.88%，优化后的液化烃罐区可燃气体探测器布置方案1ooN覆盖率可达到96.87%，可为泄漏事故早期预警提供技术支持。

Abstract: Liquefied hydrocarbon is a Class A fire hazard liquid. Once it leaks, it will cause serious consequences when encountering the ignition source. In order to effectively prevent the gas leakage of liquefied hydrocarbon storage tanks, this paper takes a petrochemical liquefied hydrocarbon tank farm as an example, using FLACS software to simulate the leakage of liquefied hydrocarbon and the distribution of flammable vapor clouds. The gas detector layout plan is evaluated, and an optimized plan is proposed. The results show that the coverage rate of combustible gas detectors under the original layout plan is 46.88%, the optimized arrangement of combustible gas detectors for liquefied hydrocarbon tank farms has a 1ooN coverage rate of 96.87%, which can provide technical support for early warning of leakage accidents.
