Abstract
The report gives procedures to measure H2SO4 vapor or aerosols in controlled or uncontrolled flue gas streams. The method was designed to operate at temperatures up to 250C with 3000 ppm SO2, 8-16% H2SO4, and up to 9 g/cu m of particulate matter. The basis of the method is the clean separation of particulate matter, H2SO4 vapor, and SO2. A heated (>250 C) quartz filter system removes the particulate matter, but passes most of the H2SO4 vapor to a modified Graham condenser. There the gas is cooled to about 62 C to condense and collect the H2SO4 vapor while passing the SO2 and H2O vapor. The condensed acid is titrated with either NaOH using bromophenol blue indicator or Ba(ClO4)2 using Sulfonazo III as the indicator. The laboratory coefficient of variance is + or - 6% and the estimated field accuracy is + or - 11%. Fly ash on the filter was shown to reduce the recovery of H2SO4 by 12% at the 10 ppm H2SO4 level. Field experiments showed that as little as 0.1 ppm H2SO4 could be detected.
