Abstract:
The Low Temperature Mercury Control, or LTMC, process is a technology developed by us for controlling mercury emissions from coal-fired power plants. In the LTMC process, mercury emissions are controlled by cooling the exhaust flue gases with an air heater (or water spray) beyond the typical 300° F. to about 200-220° F., thereby promoting mercury absorption on the coal fly ash. The fly ash containing the absorbed mercury is then captured in the power plant's existing particulate collection device. An alkaline material, magnesium hydroxide slurry in our tests, is injected to eliminate sulfur trioxide (sulfuric acid) which could otherwise condense at the cool temperature and corrode or foul the power plant's air heater and ductwork.
