Emissions and Process Gas Characterization

emissionsKey Words: gas sampling, syngas, vehicle emissions, stationary emissions, process gas, chemical characterization, HAPs

DRI has extensive experience sampling and characterizing emissions from mobile and stationary sources, with particular emphasis on quantifying trace levels of particulates (PM10, PM2.5), inorganic ions, and individual volatile organic compounds (VOCs) such as aldehydes, ketones, organic acids, and specific hazardous air pollutants (HAPs). This expertise has been extended to process gas applications, for sampling and characterizing trace species in synthesis gas (syngas), biofuel process gases, off-gassing of pellet fuels, and other processes. A portable, dilution sampling system has been developed at DRI, and is used in this work to enable reliable determination of emission rates.
