Abstract: The sulfidation and oxidation reaction of Fe2O3 and H2S in oil tank containing sulfur were simulated under aerobic condition. In order to evaluate the pyrophoric tendency of H2S corrosion product, the temperature changes were measured during the oxidation process. The effect of water on pyrophoric tendency of H2S corrosion product was investigated. The results showed that water had important influence on the pyrophoric tendency of H2S corrosion product. The pyrophoric reactivity was high in the corrosion product when  Fe2O3 sample contained some water. But the pyrophoric reactivity of H2S corrosion product was lower when there was no water or too much water in  Fe2O3 sample. With the same water containing, the higher the O2 concentration in the mixture of sulfidation gas was, the greater the pyrophoric reactivity of H2S corrosion product was.

摘要: 以F e2O3 为例, 模拟含硫油品储罐中硫化氢气体在有氧条件下的硫化及氧化反应, 测定氧化过程中试样温度变化评价硫化产物的自燃性, 考察F e2O3 试样含水率对硫腐蚀产物自然性的影响。结果表明, 水是影响 F e2O 试样硫化产物自燃性的重要因素; 试样含有少量水时自燃性最高, 干燥试样或含水率过高硫腐蚀产物的自燃性较小; 在相同含水率下, 混合气体中氧气体积分数越高, 硫腐蚀产物的自燃性越低。
