ADA-ES Guarantees Mercury Emission Reductions

ADA-ES and NORIT Americas provide powdered activated carbon injection (ACI) and storage systems to reduce mercury emissions from coal-fired power plants; and ADA-ES guarantees that the systems will reduce emissions to levels that are below their design limits.

ADA-ES has performed over twenty-five full-scale power plant mercury measurement and control tests in the past five years on a wide variety of plants across the United States. This experience has enabled them to develop the expertise and databases to accurately predict the emissions performance of their mercury control systems on most types of coal and with a wide range of air pollution control configurations. When designing a mercury system for a new customer's plant, they analyze:

· The characteristics of the plant's coal supply

· The temperatures and constituents of the flue gas exiting the boiler

· The particulate control system and SO₂ mitigation systems.

Once these factors are carefully studied, ADA-ES is in the position of being able to make a mercury emissions performance guarantee for the system.

Since mid-summer of last year, the ADA-ES/NORIT team has signed contracts for the sale of nine ACI systems to be installed on 4500 MW of capacity at three existing and four new coal-fired plants. The owners of many of these plants have taken ADA-ES up on their offer to guarantee the performance of their systems.
