چکیده مقاله:
Fires in atmospheric tanks, which are widely used in chemical process industries, are rare. Still, if they occur, they will have irreparable environmental consequences; thus, this study aimed to model and evaluate the environmental consequences of pool fires and determine the area. The restriction was performed due to the presence of a benzene pyrolysis tank. The consequences of accidents regarding an atmospheric storage tank in a petrochemical complex were investigated with PHAST ۸.۲۲ software. After qualitative risk assessment, four scenarios were selected in two weather conditions. Consequence modeling was performed using the relevant data, and after analyzing the results of a pool fire, the resulting restricted area was determined. With increasing leak diameter, the consequences of a fire were wider; the restricted area of about ۱۰۰ meters in scenario S۴ was more than in the other scenarios due to the formation of a pool fire in the hot season. The restricted area resulting from the consequence of the pool fire with a delay in scenario S۲ in the cold season was also equivalent to the consequence of both types of pool fires in scenario S۳ in the hot season and was ۸۸ meters. Atmospheric conditions also affected the consequences of pool fires. The occurrence of a pool fire also affected some of the side reservoirs. Therefore, designing a comprehensive emergency action plan is suggested in which domino events and the reciprocal consequences of disturbed reservoir accidents are examined through outcome assessment.
