| 摘 要： | 含硫油品储罐内壁腐蚀产物(Fe2O3、Fe3O4、Fe(OH)3)与H2S反应生成硫化铁,硫化铁的氧化放热是引起储罐火灾的主要原因.实验模拟了油品储罐中硫化铁的生成,研究了在无氧条件下H2S气体与油品储罐内壁腐蚀产物的反应以及生成的硫化铁在自然环境下的氧化自燃性.结果表明,Fe2O3、Fe3O4、Fe(OH)3,以及它们的混合物经硫化后生成的硫化铁具有很高的自然氧化活性,在自然环境中,常温下能迅速和空气中的氧气反应并放出大量的热,热量积聚引起储罐火灾爆炸事故.在实验结论的基础上,提出了一些行之有效的安全防范措施.

| Abstract: | Fire in oil storage tank is mainly caused by the thermo-oxidation of iron sulfide which is the reaction product of corrosion products(iron oxide rad, iron oxide black,iron hydroxide) with hydrogen sulfide in the oil storage tank containing sulfur.The formation process of ferrous sulfide in oil tank is simulated,and the reactions of corrosion products with hydrogen sulfide under the conditions of oxygen free at low temperature are studied,and then the spontaneous combustion of the formed ferrous sulfide is a... |
