The preservation of our environment calls for waste incineration and the re-use of limited resources. This includes the re-melting of metals. From these processes, pollutants are emitted in the flue gases. These pollutants have to be caught before it can escape through the stack, because they are a serious threat to public health.

Installations have been developed to remove dust, acid and heavy metals from the flue gases of incineration furnaces. However, the elimination of low concentrations of toxic dioxin, mercury and other trace elements requires an extra treatment – injection of Norit powdered activated carbon (PAC). This is a simple, extremely economic, safe and easy-to-use technology in new or existing flue gas treatment systems. PAC is blown or drawn into the flue gas flow. Dioxins and mercury are adsorbed by the PAC. The powdered carbon is removed by bag filters or electrostatic precipitators. This process yields an efficiency of more than 99.9 percent for dioxin removal and 98 percent for mercury.

“Norit products have been used for flue gas cleaning since 1986, and Norit activated carbon was the first among these products to be used for this purpose. Since then it has been successfully used by an ever-growing number of customers, and to their complete satisfaction”, Bert van den Akker, application specialist. “Norit not only has the appropriate carbon in house, but also the know-how and means – such as dosing systems – to use the carbon with success”. Norit is worldwide market leader in this segment.
