SCR Technology – Ready for the Future

Kai Klinder, Business Director IPE Europe, gave a lecture on the advantages of selective catalytic reduction (SCR), in front of approx. 120 executives and experts in a workshop at “Berliner Abfallwirtschafts- und Energiekonferenz”, which took place at the end of January 2012.

In particular with regard to the coming amendment of the “17. Bundesimmissionsschutzverordnung”  (Federal Immission Control Ordinance) Johnson Matthey’s modern SCR technology has proven itself as a good option for the future. The amended version of the regulation states that starting from 2013 the nitrogen oxide limit value will be halved to 100 mg/m³ for all new waste incineration plants with a heat capacity of 50 MW and more.

Although these specifications can be also held with the SNCR-procedure, commonly used up to now under favourable conditions, the SCR-technology can reach lower values of less than 30 mg/m³ and conversion rates of more than 95 %. In addition to nitrogen oxides, dioxins and furans are also reduced.

Johnson Matthey has already delivered SCR plants to Norway, Italy and Germany which reliably go below the limit value of 100 mg/m³. Furthermore, modern SCR-technology can operate at lower temperatures starting from 160 degrees C. This means that reheating can be avoided and a significant decrease of the operating costs is possible.
