The coal industry in the United States has made great strides in reducing emissions, with the reductions of SOx and NOx as prime examples. The need for environmental emissions control will continue to increase, however, as the industry and the public push for near zero emissions from coal-fired plants. The Clean Air Interstate Rule (CAIR) and Clean Air Mercury Rule (CAMR) are examples of Clean Air Act regulations being addressed right now by the power industry.
In collaboration with industrial partners and the National Energy Technology Center (NETL), WRI is advancing innovative mercury reduction and emissions control technologies for coal-fired power plants.
Our Combustion Test Facility is a pilot-scale utility furnace that mimics a full-size utility burner for testing alternative fuels and emission control technologies. Our Sorbent Test Facility can be tailored to simulate oxidizing and reducing conditions, allowing us to evaluate carbon and non-carbon based sorbents at high temperatures for combustion and gasification applications.
WRI is developing a patented process for removing mercury and other hazardous air pollutants from coal prior to combustion, and we’re advancing oxy-combustion for carbon dioxide removal from power plant emissions. WRI is also the testing site for the Carbon Thief control process developed by NETL.
With the Environmental Protection Agency, the National Institute of Standards and Technology and the Electric Power Research Institute, we’re developing traceable calibration standards for mercury continuous emissions monitoring―a key component in preparing the industry to meet the Clean Air Mercury Rules.
Our experienced team is available to support the development of promising new approaches to emissions control.
