Study on the Evaluation of Radiant Heat Effects of Oil Storage Tank Fires Due to Environmental Conditions

In general, plant facilities are to large-scale production facilities for oil refining, power generation, and gas . Various raw materials are handled according to the purpose of the facility, and in particular, there are various facilities in Korea that process petrochemical products as raw materials. As most of the raw materials and products handled by these plant facilities are combustible, the potential fire risk at such plant facilities is very high. In this study, the fire risk of plant facilities was evaluated by analyzing the performance degradation of structural members through real experiments and data analysis assuming the ignition of raw materials used in petrochemical plants.

Predicting the Heat Release Rate of the Storage Tank Pool Fires Using the Liquid Vaporization Model

This study is a preliminary research to specify fire scenarios in storage tanks and evaluate the fire size based on the type of fuel and diameter of the storage tank by applying the liquid evaporation model of FDS . FDS version 6.7.6 was used in the analysis, and the computational domains were established based on the pool diameter with the same proportion. The results obtained from the FDS model indicated that the heat feedback to the fuel surface was relatively well matched with the previous empirical correlations and experimental results. The FDS model showed a relative error within 15% compared with that of previous empirical correlation and showed excellent linearity with respect to the size of the analyzed fuel. The present study contributes to expanding the applicability of FDS models in the fire safety analysis of large storage facilities. Additionally, a comparison analysis with experimental results is required to assess the reliability of heat release rate estimation.

Fire Risk Analysis of Petrochemical Plant Facilities through Fire Modeling

In this study, fire case analysis and fire type and risk analysis were conducted for each process according to the ISO 17776 checklist to determine the firefighting activities and worker evacuation areas in case of a fire in a petrochemical plant. Therefore, fire modeling was performed for storage tanks with the largest fire load according to the wind speed and combustibles in order to analyze the radiant heat and smoke behavior. The effects of radiant heat and smoke were increasingly high in the order of n-heptane, gasoline, and diesel. Moreover, the firefighting activities and worker evacuation areas varied greatly depending on the wind speed rather than combustibles. However, because the results of the study cannot exclude the possible dependence on the fire modeling, it is necessary to generalize and standardize the results of the study by accumulating data through various scenarios.
