【摘要】 含硫油品储罐中,由于硫腐蚀形成的主要硫化产物硫化亚铁的氧化放热是引起油品自燃的主要原因.对硫化亚铁的自然氧化进行了跟踪实验,考查了硫化亚铁自然氧化的温度变化特征,绘制了不同条件下硫化亚铁的氧化升温曲线,分析了水分、油品及空气流量对氧化升温特征的影响,为实际生产提供了有利的理论依据.更多还原

【Abstract】 The oxidation and heat-release of main sulfide product-ferrous sulfide is the main cause for the spontaneous combustion of oil in tanks. The tracking tests of natural oxidation of ferrous sulfide were carried out by means of a natural pyrophoric test system in the study. The dynamic change characters of temperature of ferrous sulfide in the oxidation reaction was studied and the oxidation temperature-rise curves in different experiment conditions were obtained by testing the relation between the temperature of ferrous sulfide and the oxidation reaction time. In addition, such factors as humidity, oil and air flow influencing the dynamic change characters of temperature of ferrous sulfide were analyzed.更多还原
