| 摘 要： | 基于Aspen Plus工业系统流程软件,建立了气流床气化系统中的洗涤冷却室模型,模拟预测了入口合成气的温度、压力和洗涤冷却黑水的温度、水量等操作参数对洗涤冷却室出口合成气水汽比的影响,并对洗涤冷却过程进行了热力学分析。模拟结果表明:入口合成气或洗涤黑水的温度升高使洗涤冷却室的温度升高,出口合成气的水汽比增大;出口合成气的水汽比随进口合成气的压力升高而减小;洗涤冷却室入口黑水流量增大,出口合成气的水汽比有所降低。对洗涤冷却室的分析的结果表明:随着洗涤冷却室室内压力增大和入口合成气温度的升高,洗涤冷却过程的损失增大。

| Abstract: | The effects of temperature and pressure of the inlet syngas and temperature and flow rate of the scrubbing-(cooling) black-water on the water/vapor ratio of the outlet raw gas from the scrubbing-(cooling) chamber were simulated and investigated using a scrubbing-cooling chamber model built on the Aspen Plus software.The simulation results show that temperatures of(inlet) syngas and/or scrubbing-cooling black-water would affect the water/vapor ratio of outlet raw gas by affecting the water evaporation rate i... |
