Accident consequence simulation analysis of pool fire in fire dike

摘要

Pool fires are the most common of all process industry accidents. Pool fires often trigger explosions which may result in more fires, causing huge losses of life and property. Since both the risk and the frequency of occurrence of pool fires are high, it is necessary to model the risks associated with pool fires so as to correctly predict the behavior of such fires. In this paper, the petrochemical tank area of a chemical enterprise in Tianjin is selected as a study case, for the basic features of reserve materials and the specific circumstances of the storage tank area, hazard analysis and damage area of its pool fire in fire dike according to the model calculation and CFD simulation are discussed. The results showed that the strong thermal radiation of pool fire could destroy adjacent tanks, equipments, and public pipe, and even cause serious casualties within the scope of 28.46 meters. When the fire separation distance between tanks, tank and pipeline, tank and other buildings is more than 69.71 meters, the production equipment could not be damaged, and the production personnel inside could not be injured.
