RISK AND SAFETY ANALYSIS OF CHEMICAL PLANTS. CASE STUDY: THE CATALYTIC REFORMING UNIT OF A REFINERY

THE OBJECTIVES OF THIS DISSERTATION ARE: 1. TO REVIEW AND EVALUATE THE METHODS FOR RISK AND SAFETY ANALYSIS WHICH WERE PRIMARY DEVELOPED FOR NUCLEAR POWER PLANT AND CHECK THEIR APPLICABILITY TO CHEMICAL INSTALLATIONS. 2. TO CONTRIBUTE TOTHE FORTHGOING OF SCIENCE IN THE DOMAIN OF RISK AND SAFETY ANALYSIS OF BY THEIMPROVEMENT OF THE DYLAM METHODOLOGY IN BOTH SENSES: FIRST IMPROVEMENT OF SOFTWARE AND SECOND ENLARGEMENT OF APPLICATION AREAS. 3. TO PRESENT A STANDARD RISKAND SAFETY ANALYSIS OF QUITE TYPICAL CHEMICAL PLANT SUCK AS THE NAPHTHA CATALYTIC REFORMING UNIT OF A REFINERY MODELLING ON THE ONE HAND THE CONSEQUENCES OF A PLAUSIBLE ACCIDENT AND HIGHLIGHTING ON THE OTHER THE STILL EXISTING METHODOLOGICAL LIMITATIONS.Η ΕΡΓΑΣΙΑ ΑΥΤΗ ΕΚΠΛΗΡΩΝΕΙ ΤΟΥΣ ΠΑΡΑΚΑΤΩ ΣΤΟΧΟΥΣ 1.

Statistical Analysis of Major Accidents in Petrochemical Industry Notified to the Major Accident Reporting System (MARS)

The European major accident reporting system (MARS) was created within the framework of European Union (EU) directive 82/501, the so-called “SEVESO” directive, and in order to register all the major industrial accidents notified to the European Union authorities from the member states. Statistical analysis of these accidents offers significant data to the understanding and prevention of industrial accidents. This paper makes an analysis of some characteristics of major accidents in the petrochemical sector included in MARS. The statistical analysis focused on the main categorization fields of the MARS short reports and additionally a refinement of the immediate causes of major accidents with focus on the organizational factors was attempted through the details provided in the full reports of the database.JRC.G.4-Maritime affair
