In recent years， due to corrosion caused by sulfur oil refining， storage and transportation equipment， such as frequent accidents leaked to the business causing huge economic losses， analyze the cause of the accident found that iron sulfur compounds lead to the spontaneous combustion is the main reason for the This article study the oxidation of sulfide exothermic reaction product of activity of factors， from a theoretical and experimental analysis of sulfur exothermic oxidation of iron compounds on fire and explosion caused the cause of the accident in order to raise oil storage tank to prevent fire and explosion Study of different ambient temperature 15 ℃， 25 ℃， 50 ℃， 75 ℃ conditions， oxides of iron sulfide oxidation product of On the tank of sulfur compounds of iron sulfide formation and the oxidation product of burning oil for a theoretical analysis of the principle of sulfur oxidation of iron compounds in the dynamic changes of temperature and iron sulfur compounds the impact of certain factors oxidation system Experimental study has also examined in depth， combined with storage and transportation of oil processing and the actual situation in the process of influencing factors on the oxidation rate of the analysis and discussion， mapping products under different conditions sulfide oxidation temperature Theoretically explained by the oxidation of sulfur compounds exothermic iron and fire and explosion caused the cause of the accident， and according to the experimental data and oxidation temperature curve of economic and effective preventive 应该是这样
Abstract recent years， because the sulfur corrodes accidents and so on refinery which， storage and transport equipment revelation occurs to occur frequently， creates the huge economic loss to the enterprise， the analysis accident cause factor discovered that the iron pyrites spontaneous combustion is the primary cause which the initiation this article inspects the curing product the oxidized exothermic reaction active influencing factor， catches fire from the theory and the experimental result analysis iron pyrites oxidation exothermic initiation with explosion accident's reason， thus proposed that prevents the oil quality storage tank to catch fire with the detonation inspects under the different ambient temperature 15℃，25℃，50℃，75℃ condition， hard oxide compound curing product oxidized The iron pyrites formation and the curing product's oxidation caused the oil quality combustion principle to the storage tank to carry on the theoretical analysis， the temperature tendency change rule and the influence iron pyrites oxidation tendentious factor carried on the system and the thorough experimental study to the iron pyrites oxidation process， in the union petroleum processing and the storage and transport process actual situation carries on the analysis and the discussion to the oxidation rate influencing factor， under the plan dissimilar condition the curing product oxidation heating Theoretically the explanation the fire which and explosion accident's reason exothermic initiates by the iron pyrites oxidation， and according to the empirical datum which and the oxidation heating curve obtains proposed the economy， but effective preventive key word curing temperature， iron pyrites thing， ferric oxide curing， oxidized tendentiousness
