Abstract
A particulate separation system for accurate measurement of vapor-phase mercury in a flue gas stream uses an inertial gas sampling filter in which the skin temperature of the filter element is controlled to allow vapor-phase mercury measurements while minimizing measurement artifacts caused by: (1) mercury thermally desorbing off particulates into the gas stream; and (2) mercury being removed from the vapor phase by collection on particulate matter at the gas/particle separation interface.
