Flue gas desulfurization test by using reproducible organic amine

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.
