The EERC is internationally recognized for its groundbreaking work in the development
of control technologies to reduce emissions from mobile and stationary sources worldwide
, mercury, and fine particulate matter). The EERC’s
Emission Control Technologies Center has conducted hundreds of industry-driven projects
ranging from fundamental studies of system interactions to pilot- and full-scale
slipstream testing of advanced technologies that offer solutions to meet clean air
requirements well into the next century.
The EERC has the facilities and expertise to develop, test, and commercialize retrofit
options for acid gas control and particulate removal as well as state-of-the-art
technologies for use in new facilities. Additionally, EERC facilities provide an
ideal setting to conduct well-controlled simulations critical to the design of the
next generation of equipment needed to meet future inorganic and organic emission
regulations for utilities, incinerators, refineries, and other industrial sources.
In addition to removing air toxics and particulate matter from emissions, the EERC
is focused on environmentally sound uses for, and disposal of, these constituents.
The EERC has extensive experience in waste utilization for value-added products,
appropriate disposal practices, environmental monitoring, and land reclamation.
Atmospheric Emission Control
The EERC is a world leader in the development of technologies to remove SO2
(sulfur dioxide), SO3
(sulfur trioxide), NOx
(nitrogen oxides), and other particulate matter from coal-fired power plants and
other industrial sources. The U.S. Environmental Protection Agency (EPA) has designated
the EERC as the Center for Air Toxic Metals
). CATM focuses on research, development, demonstration,
and commercialization of technologies to minimize the environmental impact of mercury
and other air toxic metal pollutants on the environment worldwide. Through partnerships
with government agencies, industry, and environmental groups, CATM has answered
critical questions concerning:
Center for Air Toxic Metals
- Potential health risks.
- Toxic metal transformations.
- Sampling and measurement of toxic metal emissions.
- Related toxic metal control technologies.
The EERC is recognized worldwide for expertise in understanding mercury in air,
soil, and water and for research to develop valid techniques for measuring mercury
emissions from power plants. The mercury emitted into the atmosphere from the stacks
of coal-fired boilers has been mandated to be regulated by EPA. The EERC is developing
and testing technologies to control mercury emissions from a variety of fuel ranks
in an efficient and cost-effective manner.
Mercury Control and Measurement
Fish, Mercury, and Nutrition
Advanced Hybrid Particulate Collector
The EERC is commercializing EERC-developed particulate control technologies. The
patented advanced hybrid particulate collector technology underwent full-scale demonstration
at Otter Tail Power Company's Big Stone, South Dakota, power plant, and in Cagnano,
Italy, at a cement kiln owned by Sacci. Both facilities demonstrated greater than
99.99% control of fine-particle emissions.
Implementing regulations to control mercury emissions has led to a significant increase
in research that involves measuring mercury in flue gas emissions at power plants
across the country. The EERC has the unique ability to perform sampling and analysis
in the field while at the same time maintaining an exceptionally high level of quality
control and quality assurance. Sampling crews ranging from four to 14 researchers
and technicians annually travel to nearly a dozen locations across North America,
using state-of-the-art equipment to monitor emissions at power plants for up to
30 days in duration.
Waste Utilization and Disposal
Substances removed with atmospheric emission control technology must be properly
utilized or disposed of. The EERC has extensive experience in waste utilization
and disposal, particularly in mined land settings. The EERC works with coal combustion
by-product (CCB)-related issues and promotes the environmentally safe, technically
sound, and economically viable utilization and disposal of these highly complex
Coal Ash Utilization and Management
The EERC’s Coal Ash Research Center is dedicated to improving the technical and
economic aspects of coal ash by-product management. Its multifaceted team of researchers
takes a comprehensive approach to solving a wide array of by-product issues from
utilization to disposal.
- Environmental analysis
- Engineering evaluations
- Market research
- Product development
- Field demonstrations
The Coal Ash Research Center is a consortium of industry and government representatives,
scientists, and engineers working together toward a common goal: to advance coal
ash utilization. Specifically, the Coal Ash Research Center works to solve coal
combustion by-product (CCB)-related problems and promote the environmentally safe,
technically sound, and economically viable utilization and disposal of these highly
Founded in 1985, the Coal Ash Research Center has made the following advancements
in the area of coal ash utilization:
Coal Ash Research Center
- Generation of scientific and engineering information applicable to CCB regulations and specifications.
- Development of improved CCB characterization methods.
- Demonstration of new and improved CCB use applications.
- Transfer of technical information and technology.
