Background & objective: Oil storage tanks are major industrial facilities which always pose risks of toxic substance release, fires and explosions. Fire has been recognized as the most common risk associated with such facilities, while explosion is the most important one in terms of ability to claim human lives and damage property. The current study aimed at investigating and modeling the effects of fires occurring in a gas condensate tank farm, according to which the level of possible emergencies were specified using the guidelines provided by the Center for Chemical Process Safety. Lastly, control measures were recommended.

Methods: In the present study, the release and leakage of gas condensate from floating roof tanks were assessed using HAZOP method. Then, using PHAST software, the amount of radiation intensity received by the surrounding environment was determined, safe boundaries were computed, and according to the CCPS standard the emergency levels were determined.

Results: modeling was performed based on the maximum capacity of tanks for both cold and hot seasons. The results revealed that safe distance for a maximum amount of irradiation density (4 KW/m2) related to a sudden release were 60 and 140 meters, respectively.  

Conclusion: according to the current condition of the plants and storage tanks, a plan was recommended for emergency management and practical suggestions were provided to improve the reliability and consistency.
