Еxplosion, a cloud of gas-air mixture, explosion level, probability of an emergency.Abstract
Context. Science-based ranking of potential danger levels characterizing technological units at gas-oil reprocessing enterprises needs to address safety issues at all stages of their life cycle. Actual Ukrainian normative and methodological framework is insufficient to meet the challenges of explosion at gas-oil reprocessing enterprises in current economic conditions.
Objective. Designing and analyzing mathematical model of tehnogenic emergency with the explosion of gas-air mixture clouds on block of gas-oil reprocessing technological enterprise as the constructive tool for quantify definition of explosive unit level.
Method. Structural and parametric identification of integral criterion characterizing the unit explosiveness as a whole taking into account the peculiarities of enterprise territory development, the explosion regime, characteristics of explosive materials.
Results.The problem of explosion hazard level estimation of separate technological equipment and whole technological block of a gas and oil refinery plant is solved in the work.
Conclusions. The proposed method is a contribution to further development of the methodology and constructive means to ensure the technologic safety, in particular the explosion one, for potentially hazardous industrial objects. Numerical results allow us to recommend the proposed method to be used in practice.References
