摘要
研究了高温条件下硫化氢的硫化腐蚀状况及腐蚀产物的自然氧化倾向性。并采用X-射线衍射仪鉴定了硫化产物组成。对硫化产物进行了氧化反应,分析了不同铁的氧化物、硫化温度和环境温度对产物自然氧化倾向性的影响。结果表明,高温硫化氢腐蚀的产物主要是FeS,还有部分其他类型的硫铁化合物。H2S高温腐蚀产物自然氧化倾向性由大到小依次为Fe2O3,Fe3O4,Fe(OH)3;在硫化温度高于300℃和环境温度高于75℃时,硫化腐蚀产物的自然氧化倾向性较大。
The erosion of hydrogen sulfide and the nature oxidation tendency of erosion products were studied at elevated temperature. The sulfidation products were analyzed by XRD. The oxidation reaction of sulfidation products was carried out to investigate the effects of different iron oxides, sulfidation temperature and environment temperature on the nature oxidation tendency of sulfidation products. The results show that the main product is FeS during high temperature sulfidation of H2S. And some other types of iron sulfides are found in the erosion products. The results demonstrate that the nature oxidation tendency of products formed by Fe2O3 , Fe3O4, and Fe（OH）3 with H2 S is weaker respectively. The nature oxidation tendency of sulfidation products is stronger when the sulfidation temperature is higher than 300℃ and the environment temperature is higher than 75℃.
