Study on the Experiment of Simultaneous Removal of SO2 and NOx Using Urea/KMnO4 Solution

  • 摘要: 采用尿素和KMnO4配制成的吸收液,在填有金属鲍尔环的柱式喷淋吸收反应器中,对模拟烟气进行湿法烟气同时脱硫脱氮研究.结果表明:采用尿素和KMn04配制成的吸收液可以高效地脱除模拟烟气中的SO2和NOx,脱硫脱氮率平均分别达到99.6%和62.5%;反应吸收液中主要含有因吸收NOx和SO2而生成的NO3-,NO2-,NH4+和SO42-等离子;NO3-,NO2-和NH4+的生成曲线及尿素的消耗曲线均为线性,其速率常数分别为0.009 1,0.0074,0.091 6和0.950 8 mmol/(L·min).吸收反应为零级反应.
