Air Pollution Control Evaluations and Performance Assessments

Geosyntec's air quality practitioners provide our clients with a broad set of services for emission control device monitoring, evaluation, and optimization. We frequently evaluate emission controls operating under the most complex conditions and advise clients on potential avenues for optimization that meet emission standards and minimize the operational costs of their facilities.

Our project portfolio includes combustion management and tuning for boilers, thermal oxidizers, and other combustion devices. We also have expertise in the measurement of complex pollutants such as mercury and sulfur trioxide (SO3) as well as standard control device emission measurements and U.S. Environmental Protection Agency (EPA) test methodologies.

Geosyntec offers installation of state-of-the-practice hardware and software that utilizes cross-duct laser technology for continuous monitoring of ammonia (NH3) and SO3. We also provide Continuous Emission Monitoring System (CEMS) selection and operational assistance, data management, and equipment maintenance to provide maximum equipment up-time and efficiency.

In addition, Geosyntec practitioners have expertise in process design as well as air pollution control technology design that enables us to develop strategic approaches to complex, multi-pollutant emission challenges. Our process engineering and air pollution control technology experts provide clients with a balanced approach to their plant operations.

Geosyntec practitioners continued to advance the state of the practice for emission controls and frequently collaborate with colleagues at the U.S. EPA, the U.S. Department of Energy, the Electric Power Research Institute, and others on new strategies for reducing impacts to air quality. These include devices and systems for nitrogen oxide control, mercury capture, scrubber optimization for heavy metals, catalyst selection and optimization, and plume opacity mitigation. Through additional research, our experts have developed emission measurement methodologies that enable pollutant-specific measurements under highly complex operating conditions.

In just one project example for a client in the electric power industry, Geosyntec helped to select a portable mercury analyzer that accurately quantified elemental and oxidized mercury concentrations in flue gas at multiple locations between a power plant's selective catalytic reduction outlet and a stack. The client needed the ability to monitor the gas in real time for extended engineering studies that examined how the plant responded to different operating conditions in preparation for compliance with the U.S. EPA Mercury and Air Toxics Standards (MATS).

Our engineers and scientists aided the utility in identifying and installing the best process monitors for their particular needs and modified the vendor technology by adding wireless data transmission functionality and the ability to calibrate the flue gas monitors remotely. We also examined the operational effects of the technology on flue gas mercury concentrations and identified opportunities for mercury reduction through operational changes.
