摘　　要：介绍了一种新型的自制有机胺脱除烟气中SO2的方法。通过对一系列有机胺类吸收剂对SO2吸收能力和吸收率的比较,结果显示自制有机胺对SO2有较高的吸收容量和吸收率,所以选其作为最佳吸收剂进行工艺研究。通过改变自制有机胺浓度、吸收剂的初始pH值、吸收温度和解吸温度,确定了自制有机胺吸收SO2的工艺参数:自制有机胺浓度为1.0mol/L,pH值为8,吸收温度为50℃,解吸温度和解吸时间分别为110℃和60min。A novel self-made organic amine used for removing SO2 from exhaust gas is introduced.Through contrasting absorptive capacity and the absorption rate of a series of organic amines,self-made organic amine was selected as the main part of flue gas desulfurization because of its higher capacity for absorption of SO2 and better absorption rate.By changing the organic amine concentration,the initial absorber pH value,the absorbtion temperature and the desorption temperature,the test results show that the desulfurization liquid concentration is 1.0 mol/L,desulfurization liquid pH value is 8,absorbtion temperature is 50 ℃,the desorption temperature is 110 ℃,and the most appropriate desorption time is 60 min.
