Essen and Luxembourg, 15 January 2009. Salzgitter Flachstahl GmbH decided to invest in a flue gas treatment plant which will enable the sinter plant of the Salzgitter (Lower Saxony, Germany) works meeting the stringent conditions of the German “TA Luft” environmental legislation.
The order for engineering, supply, erection and commissioning of this plant has been awarded to Paul Wurth Umwelttechnik, Essen, Germany.
The Paul Wurth EFA™ Flue Gas Desulphurization technology utilizes an entrained flow absorber with hydrated lime and lignite coke as reagents; thus, hydrochloric and hydrofluoric acids, dioxins and furans are bound in addition. These reactions are followed by bag filter dry cleaning of the gas, down to extremely low dust content.
Comparatively low specific consumption of the reagents and moderate investment cost brought the operator to favour the EFA™ technology.
The new gas cleaning facility will be installed downstream of the existing electrostatic precipitator and main blower; more than 680,000 m3/h (STP) of sintering off-gas are going to be processed.
The project schedule foresees commissioning of the plant in March 2010.
