Production of activated char for cleaning flue gas from incinerators
- Illinois State Geological Survey, Champaign, IL (United States)
A granular activated coal char suitable for removing dioxins, furans, mercury, particulate matter, HCl, HF and SO{sub 2} from incinerator flue gas has been produced from the Colchester (Illinois No. 2) coal. Tests with 250 kilogram of this adsorbent on flue gas from a commercial incinerator in Europe demonstrated that its efficiency for removing dioxins and furans was 99.72% to 99.98%. Mercury concentration in the flue gas after the adsorber was too low to be detected; an efficiency for mercury removal could not be calculated. This adsorbent was produced in three steps from 1 mm by 6.4 mm coal obtained from a commercial Illinois washing plant. The projected cost for manufacturing the adsorbent is lower than that of carbon adsorbents commercially available in the United States (U.S.). The estimated break even cost for the adsorbent from an 80,000 ton/year plant is $326/ton with a 20% return on investment and a cash flow for 20 years discounted 20% annually.
