Method 19

Determination of Sulfur Dioxide Removal Efficiency and Particulate Matter, Sulfur Dioxide, and Nitrogen Oxide Emission Rates

This method is applicable to any source where the determination of one of the following three is necessary. Particulate Matter (PM), Sulfur Dioxide (SO2, and Nitrous Oxide (NOX) emission rates. Sulfur removal efficiencies of fuel pre-treatment and SO2 control devices. Overall reduction of potential SO2 emissions.
