Analysis of the fire and explosion hazard of the formation of corrosive deposits on the inner surface of tanks with sulfurous oil

Introduction. The annual number of fires at the facilities of the petrochemical industry is increasing. Spontaneous combustion of pyrophoric corrosive deposits is one of the main sources of ignition. The large damage caused by fires on tanks with sulfur oil indicates a serious danger of the formation of pyrophoric corrosive deposits on the surface of oil tanks. The purpose of the study. Analyze the fire and explosion hazard of the formation of pyro-form corrosion deposits on the surface of oil tanks. The tasks of the work: - analysis of statistics of accidents that occurred at the facilities of the petrochemical industry; - analysis of fires that occurred due to spontaneous combustion of pyrophoric corrosive deposits; - analysis of the danger of formation of corrosive deposits on the surface of oil tanks, protection systems against them. Methods. In the course of the work, methods of comparison, description, generalization were used. The information basis of the study was various literary sources, regulatory documents, materials of fire analysis at tank farms. Results and discussion. The practice of operating oil tanks during the storage of sulfurous oil and the origin of fires shows that modern methods of corrosion protection are ineffective. It is necessary to adjust the existing regulatory and legal documentation in the field of improving the fire and explosion safety of petrochemical industry facilities, to develop new, more effective means of anticorrosion protection of tanks with sulfurous oil. One of the methods to protect the oil tank from corrosion is to apply protective coatings on the inner surface of the tank. However, modern anticorrosive coatings do not have the required protective ability. Conclusion. The corrosion protection system currently used is insufficiently effective. At the same time, the problem of protecting the inner surface of sulfurous oil tanks by applying anticorrosion paint coatings has not been sufficiently studied. Therefore, a more thorough study of this issue is necessary in order to increase the fire and explosion safety of sulfur oil tanks.
