Title: Fatalness analysis on store tank oil containing sulfide
Abstract: This paper aims at presenting the author's study of the oxidation tendency of sulfides, which are given by different iron oxides reacted with hydrogen sulfide. Iron sulfide red, iron hydroxide and iron sulfide black are the main corrosive factors to the oil tank, which are liable to react with hydrogen sulfide resulting in ferrous sulfide. Since ferrous sulfide can react with oxygen in air to release heat, it may lead to the explosion and fire accident of the oil tank. The greater oxidation tendency is, the greater danger will be for the oil tank. The experimental results show that the oxidation tendency of ferrous sulfide is related to the reaction time and production method. The oxidation potential of the same sulfide through six hours' reaction proves stronger than that through half hour's, for hydrogen sulfide could react not only with the surface molecules of iron oxide, but also with the inner molecules as a result of the diffusion to produce more amount of ferrous sulfide, when prolonging the process of sulfurization. This indicates that prolonging of sulfurization may result in greater danger liability of oil tanks. The oxidation potential of the products formed by the iron hydroxide, iron sulfide black and iron sulfide red should be checked by restraining the reaction time.
