摘要

摘要: 以鄂尔多斯盆地产出的罐底含油污泥及掺配水煤浆后气化灰渣和灰水为研究对象,在对其组分及特性进行系统分析的基础上,对油泥水煤浆在气化过程中氯元素迁移规律进行研究。结果表明:油泥掺配水煤浆(5%,以质量计)的灰水组成基本不变;油泥及煤中的氯元素在气化过程主要迁移至灰水中,其余部分迁移至细灰及粗渣中;通过气化炉高温气化反应,油泥中的氯化物主要转化为HCl,气相中并无二❚英生成。

Abstract: Based on an analysis of the chemical composition and characteristics of oily sludge produced from Ordos basin oilfield and the gasification ash & ash water after mixing with coal water slurry, the chlorine migration in the gasification process of oily sludge-coal water slurry was studied. The results showed that the oily sludge mix ratio is 5% (wt) in the whole slurry, and the ash water composition is basically identical with common coal water slurry. The chlorine in oil sludge-coal water slurry is mainly migrated into ash water during gasification process, with little into the coarse slag and fine dregs. By gasification reaction the chlorine in oily sludge mainly transfers into hydrochloric acid, and no dioxins are formed in the gaseous phase.
