Application - Mercury Emission Reduction


Mercury Emission Reduction

Coal burning power plants are today's largest source for mercury pollution in the environment. The EPA, US National Research Council, the World Health Organization, and many other health agencies agree that reduction of this pollutant is required in order to maintain human health.

Bromine-containing compounds, added to the coal, or to the boiler combustion furnace, can be used to oxidize the mercury present in the coal, thereby enhancing the overall removal of mercury in downstream pollution.

ICL-IP inorganic bromides are being tailored to meet the increasing environmental demands in reducing coal-burning power plants, and ICL-IP's technical support can help such power plants in setting up mercury reduction devices and technologies.

MERQUEL®products are based on a mercury oxidizing agent recommended for use when coal fired power generators and incinerators need to reduce mercury pollution from coal burning flue gases.

MERQUEL® products act through an oxidation process whereby mercury present in the flue gas is converted into non-toxic ionic species, which are removable via downstream pollution control devices.

MERQUEL® products can be applied through direct spraying on to the ground coal feed to the boiler, or by bromination of activated carbon, injected into the flue gas.

Tests have shown that applying low dosage of MERQUEL® result in removal of over 90% of the mercury across the scrubber unit. Practically remove all mercury emission.
