Air Pollution Control Evaluations and Performance Assessments
Geosyntec's air quality clients need services for emission control, device conceptual design and selection, feasibility, monitoring, evaluation, and optimization for their facilities. We help clients evaluate emission controls under complex regulatory and operational conditions, and we advise them about how to meet emission standards. We also work closely with clients on the selection of air pollution control technologies that minimize operational costs while still meeting the stringent control efficiencies required by federal and local regulations. Selection of optimal control technology includes consideration of the potential for the generation and removal of secondary pollutants such as combustion by-products, reactive compounds, greenhouse gas emissions, or waste or wastewater streams. With expertise in process design, as well as air pollution control technology design, Geosyntec’s engineers develop strategic approaches to complex, multipollutant emission challenges. These challenges are brought about by evolving emission standards on existing equipment and operations, new capital project expansions, facilities, and emission sources. Our portfolio includes finding ways to control gaseous pollutants using methods including scrubbing, adsorption, condensation, catalytic reduction, and oxidation. We also address combustion management and best operating practices for boilers, thermal oxidizers, engines, and combustion devices. In addition, we design particulate filtration, precipitation, and collection systems, dust control approaches, and other ways to control toxic air contaminants. We measure control system performance by applying standard emission measurement protocols, United States Environmental Protection Agency (USEPA) test methods, and other acceptable evolving measurement science to determine compliance or reduction potential for common criteria air pollutants. Our work often addresses emissions of volatile organic compounds (VOC), nitrogen oxides (NOx), carbon monoxide (CO), sulfur dioxide (SO2), and particulate matter, as well as toxic air contaminants and dangerous compounds like mercury and sulfur trioxide (SO3). Geosyntec installs state-of-the-practice hardware and software that uses cross-duct laser technology to continuously monitor ammonia (NH3) and SO3. We help clients select continuous emission monitoring system (CEMS) and programs for CEM compliance with federal state and consent decree monitoring provisions. Additionally, we prepare CEM data quality assurance and quality.
