摘要：

燃煤汞污染已经成为继粉尘、SO2、NOx之后的第四大污染物，受到广泛关注。介绍了目前应用于火电机组脱汞的各种技术，及美国烟气脱汞工艺的应用情况，重点分析了活性炭喷射法和多污染物协同脱汞两种主要技术的优缺点和应用实例，并对火电机组烟气脱汞工艺路线选择提出了相关建议。

Abstract:

Coal fire-caused mercury emission has become the fourth major pollutant after dust, SO2 and NOx, which has attracted widespread concerns. This paper introduces the existing mercury-removal techniques used for coal-fired units, and the application of the US mercury control process, and highlights the features and application of two major technologies, including the activated carbon injection (ACI) and the simultaneous multi-pollutant removal technology. In the end, relevant suggestions are proposed on process route selection of mercury control for coal-fired power plants.
