气流床水煤浆气化系统中氯元素的分布
Chlorine distribution of entrained-flow coal-water slurry gasification system
摘要
Abstract
Taking Shenfu coal as objective,the samples of coal,slag,ash,fresh water and waste water of the entrained-flow coal-water slurry gasification system were analyzed,and the chlorine distribution in the gasification system was obtained.Electrolyte non-random two-liquid model was employed to calculate the chlorine distribution of overall system by Aspen Plus.The results show that the chlorine conversion ratio is 93.86％ in this system.The most part of chlorine in gasification system is discharged in waste water,while a small part is in slag streams,and only little chlorine is in gaseous streams.The mode of the occurrence of chlorine in the coal impacts the release of chlorine.In Shenfu coal,most of chlorine in the coal is in organics,sharing 94.27％,which can be released easily.The simulation result basically agrees with the experimental data.The highest concentration of chlorine is 450 mg/L in the black water of vacuum flash outlet.关键词
