Photo-degradation of P-Nitro Toluene Using Modified Risk Assessment of Gasoline Storage Unit of National Iranian Oil Product Distribution Company using PHAST Software

Abstract

The present study evaluates the risk of the gasoline tank of the National Iranian Oil Product Distribution Company (NIOPDC) in Sari region using process hazard analysis software tool (PHAST) and according to the environmental and process data of the unit. The consequences of different scenarios such as small and medium leakage, constant release rate and complete rupture were modeled and then the range of each one was obtained according to the intensity of radiation or pressure wave and the safe distances of each was determined. Due to the consequences of the explosion, the worst results were related to the weather conditions of 2/3 F for 4700, 2400, and 2300 meters, respectively. Also, based on eruptive and sudden fire data, the intensity of radiation which corresponds to the immediate death or destruction of equipment was seen in climatic conditions of (2/3 F and 4/1 D), at intervals of 180 and 160 meters distances, respectively. In these two weather conditions flammability intervals were 10520 and 450 meters. Then, by combining the severity of these accidents with the distribution of the population and the probability of their occurrence, the level of risk for these storages was determined.

A systematic review of consequence modeling studies of the process accidents in Iran from 2006 to 2022

“…This software can model different stages of release of materials (including pure or mixed materials) in the environment, including discharge, modeling materials lighter and heavier than air, evaporation from a liquid pool and finally spreading materials. In this software, both continuous and sudden releases can be modeled and atmospheric conditions are also considered as one of the input data [ 21 , 22 ].…”

A Hybrid Model for Supply Chain Risk Management Based on Five-dimensional Sustainability Approach in Telecommunication Industry

“…Development of sustainability, risk management and supply chain management are among the most important management concepts that guarantee the competitive advantage of organizations in the long run, in which risk analysis is one of the most important tools to maintain and improve the level of safety in the society and especially in industry [1]. The interconnected scope of these three scopes is "Supply chain sustainability risk management (SCSRM)", which means the management of risks that threaten the sustainability of the supply chain as illustrated in Figure 1.…”

Seismic Analysis of Double Deck Floating Roofs of Siraf Storage Tanks with Condensate, Light and Heavy Crude Oils

“…Hence, seismic analysis of floating roofs is important. The several attempts which were made toward vibration mitigation of floating roof vibration and risk assessment of petroleum storage tanks indicate the importance of this field [5][6][7][8].…”
