Quantitative risk assessment of hazardous chemical discharges and simulation of threat zones in hydrocarbon storage systems

Human activities predominantly depend on hydrocarbons, which are essential resources and pivotal drivers of economic growth and development in many nations. Countries with substantial hydrocarbon reserves have capitalized on these resources to generate wealth. However, the complex physicochemical properties of hydrocarbons pose significant risks to both human safety and environmental integrity. Hazard studies conducted across various Algerian oil (NAFTAL) regions, particularly at CBR (cost-benefit ratio) industrial sites, indicate that the primary dangers involve fire and explosion. Investigations into accidents within the ARV (Arrival) terminal zone have identified a strong correlation with hydrocarbon storage practices. This work aims to evaluate the risks associated with specific phenomena linked to the storage of gas oil products. To perform a semi-quantitative risk analysis of potential accident scenarios, we employed the hazard and operability study (HAZOP) method, alongside a detailed examination of possible incidents using the Fault Tree method (FTM). This approach elucidates the causes and consequences of undesirable events. Furthermore, we assessed the risks posed by these adverse scenarios and their implications for nearby reservoir areas. Using Areal Locations of Hazardous Atmospheres (ALOHA) software for simulation, we illustrated the identified scenarios and delineated the threat zones surrounding the S11 tank.
