Kardemir to Clean Sinter Off-Gases with Meros Technology from Siemens
01/22/2014 - Siemens Metals Technologies has received an order from Karabük Demir Celik Sanayi ve Ticaret A.S. (Kardemir), a Turkish steel producer, to supply key components to clean the off-gases from its new sinter plant No. 3.
The order comprises the engineering for the entire off-gas cleaning system and supply of the first and final cleaning stages, the latter being based on Meros technology. The purpose of the project is to drastically reduce dust and sulfur emissions. The system will be able to clean some 400,000 standard cubic meters of off-gas per hour, and is scheduled to come into operation at the end of 2014.
Kardemir is currently implementing a comprehensive expansion program at its Karabük production location, which also includes the construction of the new sinter plant No. 3. In 2012, Siemens had previously supplied this Turkish manufacturer of long products with a Merim dry dedusting system for a new blast furnace, which will shortly be brought into operation. Kardemir chose Siemens once again for the off-gas cleaning concept for its forthcoming sinter plant No. 3, which will reduce emissions to a value significantly below the statutory limit.
Siemens will handle the basic engineering of the entire plant as well as the detail engineering and supply of key components for the first and final cleaning stages. In the first stage, a cyclone separator will remove the coarse dust from the off-gas flow. The separated coarse dust will be completely recycled back into the sinter production to minimize the loss of iron. The second and final cleaning stage will work with the Meros process developed by Siemens. This involves injecting and evenly distributing adsorption and desulfurizing agents into the off-gas flow. Kardemir will use hydrated lime as an additive for desulfuization. This will enable the sulfur dioxide content of the off-gas to be reduced by over 85%. The system will be designed so that it can be later extended during operation with additional features so that also nitrogen oxides, dioxins and volatile organic compounds can be removed.
