  • Flue gas monitoring and dynamic spiking for sulfur trioxide/sulfuric acid
    Patent number: 8021617
    Abstract: Systems and methods are disclosed for measuring sulfur trioxide/sulfuric acid content of flue gas. A probe is provided that extracts two separate lines of gas samples simultaneously from the flue gas. One of the two lines is dynamically spiked with a known quantity of sulfur trioxide, preferably generated in the probe. A comparison of sulfur trioxide/sulfuric acid content measurements from the spiked and unspiked lines helps identify and adjust for inherent biases in the measuring system. Also disclosed are catalyst structures and methods for use thereof for generating sulfur trioxide at known concentration.
