Reduction of the Vulnerability Zone of a Major Industrial Risk. Case of BLEVE in LPG Storage Sphere Hassi R'Mel, Algeria

Abstract

A major risk is a rare natural occurrence bearing adverse consequences on human lives, equipment and environment as well; we must coordinate to address this issue. And with the increased number of habitations that are close to major industrial plants of high risk, a risk management is of utmost need and importance. This constitutes the rationale of our study. Throughout this work, we try to reduce the damages or at least control the targeted areas (Limit, Vulnerability) that have been affected by a major accident. Our work is very useful for handling an existing high-risk industrial installation that is close to urban areas. This research examines the volume parameter of a dangerous explosive substance as a parameter within the reach of an existing company that is near an urban area. We simulated the BLEVE phenomenon of an LPG storage sphere in Oil & Gas producing zone of Hassi R'Mel (Algeria) by using ALOHA® (V 5.4.7): a reputed tool for simulating dangerous phenomena. The article provides a methodology for the development of thermal effects (range of effect / volume) of the BLEVE phenomenon of an LGP sphere. This approach may help us during the decision-making that is relevant to determining the maximum fill level for a predefined impact area, which constitutes a second barrier of the risk reduction (limit) hierarchy. In addition, it can help us locate the risk within the scope of the company while at the same time avoiding the regulatory obligations related to industrial risks that affect populated areas.
