Evaluation of potential hazard of installations of fuel and energy complex enterprises

Operation of equipment at facilities of the fuel and energy complex is associated with an increased level of potential hazard of an emergency situation. This is due to the fact that a significant amount of explosive and fi re hazardous substances is used in the technological process. At the same time, the equipment is operated at elevated temperatures and pressures, and many media used for contact with the material have increased corrosive activity. When-ever objects are disrupted at any stage of the emergency development, three most significant adverse contributing factors are fi re hazard, explosion hazard and toxic contamination. According to the current regulatory and technical documents, there are several approaches to identifying these hazards. However, using the results obtained, it is difficult to make decisions or plan actions to reduce the potential hazard of emergency destruction and predict the timing of the critical state of the fuel and energy complex facilities. In this regard, earlier, in order to assess the potential danger of equipment of hazardous industrial facilities, it was proposed to use an integral parameter that reflects all hazard categories calculated according to the existing calculation procedures. However, the calculation of the integral parameter in these works only takes into account the physical nature of the origin of the hazards, while not enabling to assess the current state or to predict the safe operation period. Thus, improvement of the hazard assessment method on the basis of comprehensive analysis of quantitative characteristics of accidents at oil and gas refineries, to be based on a complex integral parameter of potential hazard, taking into account not only the explosion hazard, fi re hazard, and toxic damage, but also the degree of degradation of the material of each equipment, is of particular relevance.
