Initiated in January 2003, a 3-year $1.5 million University of North Dakota Energy & Environmental Research Center research project is taking a comprehensive look at the potential release of mercury and other air toxic elements from coal combustion by-products (CCBs).
Objectives
| 1. | Determine the release potential of selected air toxic elements, including mercury and arsenic, from CCBs under specific environmental-related conditions. |  |
| 2. | Create a database of information on mercury and other air toxic element releases for CCBs. | |
| 3. | Evaluate the specific mechanisms of release, including leaching release, vapor release to the atmosphere either through disposal and use or processing of CCBs, and trace element release through the action of microbes. |
Results
This effort will result in improvements to existing technologies by:
| • | Providing comparative information on CCBs from systems with various emission controls, which will aid utilities in selecting emission control technologies consistent with existing CCB management plans. |
| • | Developing scientifically sound experimental protocols for determining air toxic releases from CCBs based on CCB properties and management scenarios. |
| • | Providing information to the state and federal agencies that regulate disposal and utilization options. |
