CRI Combined Catalytic SCR and Dioxin Destruction System in Operation on the Municipal Waste Incineration Facility in the City of Como, Italy


In August 2004, the CRI combined SCR NOx reduction and catalytic dioxin destruction system was successfully commissioned at the Municipal Waste Incinerator operated by ACSM SPA Forno Incenerimento Rifiuti in the city of Como, Italy. The overall flu gas treatment system was designed, engineered and installed by CRI's Italian partner Area Impianti SpA.

The CRI system was designed to remove over 90% of the NOX in the flue gas and to achieve a dioxin outlet concentration of less than 0.05 ng TEQ/Nm3 at an operating temperature of 210°C/410°F.

NOX emissions in Europe are largely responsible for the formation of acid rain, which over the last thirty years has had a damaging effect on European forests, monuments and buildings. Dioxins and furans are extremely toxic components that can be generated in waste incineration processes, such as municipal solid, industrial hazardous liquid or medical waste.

Most European counties therefore have enacted legislation, which requires that dioxin and furan concentrations in the stack gas from waste incinerator plants must be controlled to less than 0.1 ng TEQ/Nm3.
