| 摘 要： | 石灰、石灰石是最常用的湿法脱硫剂。从反应机理、运行控制指标、液气比和钙硫比（化学过量比）、浆液循环池等方面对其性能作了比较。两者的脱硫机理、运行控制指标不同，受温度的影响程度也不同。两系统的最小液气比分别为10．0和5．6，化学过量比分别为1．05～1．15和1．25～1．60。前者的脱硫效力优于后者。

| Abstract: | Lime and limestone are the most common wet SO2 absorbent. Their property comparison is made in several aspects, such as reaction mechanism, control standard, liquid/ gas ratio, chemical excessive ratio and so on. They are different in desulfurization mechnism and control standards. Reaction temperature has incoordinately influence on both systems. The liquid/gas ratio and chemical excessive ratio of limetone system are 10 and 1.25- 1.60. The liquid/gas ratio and chemical excessive ratio of limetone system are 5.6 and 1.05-1.15 otherwise. The desulfurization efficiency of lime is better than that of limestone. |
