克劳斯硫回收装置产出黑色硫磺原因分析及处理措施

Analysis and Treatment Measures of Black Sulphur Produced by Claus Sulphur Recovery Unit in Coal Chemical Plant

针对化工厂克劳斯工艺硫回收装置产出黑色硫磺问题,分别从入装置的工艺物料、助燃剂、运行工况及上游操作情况采用排除法进行对比分析,排除无关因素,对可能的原因进行分析和对比后得出结论。结果表明:黑硫磺的产生,根源为上游工艺装置低温甲醇洗在投用时并气过快,造成产出酸性气中带甲醇,使酸性气进入制硫燃烧炉燃烧不完全所致。实践证明,可以通过调整操作的手段,避免产出黑色硫磺再次发生。

Focus on the problem of black sulphur produced by Claus sulphur recovery unit of a coal chemical plant.The process materials,combustion aids,operation methods and operation conditions were analyzed by comparison and analysis,so as to eliminate the unrelated factors.After analyzing and comparing,the conclusion is drawn.The results show that the black sulphur in the unit is caused by quickly commissioning of upstream unit,which made incomplete combustion of burning furnace so that methanol carried by acid gas.It is proved that black sulphur can be avoided by means of adjusting operation conditions.
