Risk Asseessment For LPG Storage Tanks Area In Skikda Refinery-ALGERIA Using D-Higraph And Hazop Methods & Simulation Of Dangerous Scenarios Using ALOHA Software

Abstract

In this work we present a study based on two methods D-HIGRAPH and HAZOP methods applied for the LPG storage tanks in SKIKDA refinery which is considered as the most important refinery in Algeria. Several recommendations raised from our study to improve the safety of the plant particularly since it is considered as an old plant start working since 1980. The study is completed by simulating the deduced dangerous scenarios which is the explosion of sphere S181 (for butane storage) using ALOHA software. In the following some results for thermal effect of an explosion scenario for S181 sphere
