The importance of Bromine in reducing Mercury emissions

Promoted content

There are three main reasons why we need to reduce mercury emissions.

Firstly, it’s among the top ten chemicals of concern. Secondly, human activities are by far the largest source of mercury to the environment. And thirdly, in 2013, the global community committed to reducing mercury emissions via the Minamata Convention.

Thanks to it’s unique physical and chemical properties, bromine reacts with elemental mercury which is coming out of the stacks of coal-fired power stations. It converts this elemental mercury into another form of mercury which is easier to capture than using standard emission control technologies in thermal coal-fired power stations.

Bromine-based technologies have proven themselves to be very efficient and very effective at reducing mercury emissions from thermal coal-fired power stations. The U.S. General Accounting Office report in 2009 confirmed this, with up to 90% efficiency rates for bromine-based technologies.

Along with other clean coal technologies, bromine-based technologies are helping and will continue to help to reduce mercury emissions from thermal coal-fired power stations and thus contribute to the Minamata goals.
