For the last 10 years, Chemtura’s bromine enterprise 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.

GeoBrom™ products are among the latest offerings under Chemtura’s “Greener is Better” umbrella of products, in response to the global need to cut mercury emissions from coal-fired power plants and boilers.

Studies carried out at coal-fired power plants have shown that inorganic brominated derivatives like calcium bromide or sodium bromide 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 bromine and brominated derivatives such as sodium bromide 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.

GeoBrom™ products have been designed for incorporation into new technologies that use bromine or brominated derivative products for the efficient removal of toxic mercury emissions.  It is one of many ways in which Chemtura is delivering a cleaner future through chemistry.
