我国是二氧化硫排放大国,大气中87%的SO2来自煤,消减燃煤中的SO2排放量是我国控制酸雨的根本对策。煤中全硫量是评价煤炭质量的重要指标之一,在各行业生产中,为了有效而经济地利用煤炭资源,选取相应的SO2排放控制技术,都需要对煤中的全硫含量进行严格控制。 相似文献

二氧化硫是一种重要的大气污染物,目前已被列为我国污染物排放总量控制指标之一。二氧化硫的产生主要来自煤炭等化石燃料的燃烧,因此其排放源主要是工业企业中的各种燃烧设施,属于有组织排放。有效的监控和治理二氧化硫排放依赖于准确可靠的排放监测技术。主要介绍了目前常见的工业污染源二氧化硫排放监测技术,并提出了该领域未来的发展趋势。 相似文献

A DC corona discharge reactor was applied to remove sulfur dioxide (SO2) and benzene (C6H6) from N2‐O2‐H2O mixed gas in the temperature range from room temperature to 400 °C. When SO2 was removed, the temperature elevation caused the decrease of the removal efficiency of SO2. On the other hand, the removal efficiency of C6H6 was not significantly influenced by the temperature elevation. In the simultaneous removal of SO2 and C6H6 in the relatively low temperature range below 200 °C, the removal efficiency of SO2 is significantly inhibited by coexisting C6H6. When the simultaneous removal was conducted in the high temperature range, the removal efficiency of SO2 was not sensitive against the coexisting C6H6. On the other hand, the removal efficiency of C6H6 was almost independent of coexisting SO2 at all temperatures. A hypothesis of reaction mechanism was discussed based on radical reactions with SO2 and C6H6 to explain the trend observed in the experiment. 相似文献

The citrate absorption of SO2 is currently one of the most successful and economic methods to harness sulfur dioxide pollution. In order to theoretically elucidate the mechanism of SO2 absorption by citrate solution and provide theoretical instruction for experiments and industrial process, the theory of multi-buffer solution, combined with computer numerical calculation methods, was applied to study the distribution parameters of the components of the citrate solution in the process of SO2 absorption and the following results were obtained: (1) HCi2- and H2Ci- in the citrate solution played the dominant role in the absorption and desorption processes; (2) Through the calculation for the buffer capacity of citrate solution, it was found that the pH of the absorption and desorption solution should be in the range of 2~8, while at pH=4.5 the buffer capacity reached its maximum. Some valuable parameters were obtained, which are instructive to the ensuing experiments and industrial design. 相似文献
