电厂烟气脱硫工艺选择

摘要

Three kinds of desulfurization process ： ammonia desulfurization method, limestone-gypsum method and double alkali method used in power plant were introduced and compared, and it was conclude that limestone-gypsum method is the optimal method, because the process has widely material source, long run period and high efficiency.%介绍了氨法脱硫法、石灰（石）-石膏法和双碱法3种电厂烟气常用的脱硫工艺,并对以上3种脱硫工艺进行了比较。在3种脱硫工艺中,石灰（石）-石膏法优势明显,具有原材料来源广泛、运行周期长以及效率高等优点。
