Abstract
SO2 and SO3 in flue gas of FCC were collected simultaneously by three impingers connected to a buffer flask in tanderm.The absorptive solution was titrated with barium perchlorate standard solution using thorium as indicator to determine the concentration of sulfate ion.The content of SO2 and SO3 in flue gas of FCC was calculated.The method was used for field sampling and analysis in refineries.
