GeoBrom®: The Choice for Coal-Fired Boiler Operations to Reduce Mercury Emissions

The world requires clean and sustainable energy that meets the needs of the present without compromising future generations.  LANXESS' line of GeoBrom® brominated derivative products are part of the solution; a new technology to efficiently remove toxic mercury emissions from coal-fired boilers and power plant installations.

For the last 10 years, LANXESS has focused on a “Greener is Better” approach to product development, with attention to manufacturing and new product introductions that help protect and improve the environment. The GeoBrom® product line is among the latest offerings under LANXESS “Greener is Better” umbrella of products, in response to the global need to cut mercury emissions from coal-fired power plants and boilers.

Full-scale tests carried out at coal-fired power plants have shown that inorganic brominated derivatives are effective in oxidizing mercury into species that are more easily captured on sorbents, in flue gas desulfurization scrubbers and in electrostatic precipitator units. The bromine derivatives are added to the coal prior to, or after, pulverization; to the combustion zone in the boiler; or to the flue-gas upstream of the remediation controls. Removal efficiencies of up to 90 percent have been demonstrated with these types of technologies.

Other studies have shown that inorganic brominated derivatives can be used to produce halogenated activated carbon that is injected into the flue downstream from the boiler to oxidize and capture the mercury on the sorbent. This technology has also been demonstrated to remove up to 90 percent of the mercury from the power plant units burning coal fuel.
