Abstract


In this work we present a risk assessment methodology,  Implemented based on the integration of two methods D-HIGRAPH and HAZOP. The approach is applied on the LPG storage Area in SKIKDA refinery (the most important refinery in Algeria). Several recommendations raised from the study to improve the plant safety. The study is completed by simulating the effects resulted from an explosion in the sphere S-151 (for butane storage) using ALOHA Software. In simulation, the following cases are considered: the explosion effect, the toxic material release and the thermal effect of flammable material release, the results are mapped on the refinery map to indicate the exact threated zones.
