Subsequent to supply Merim dry dedusting system to Kardemir, in 2012. Siemens to give a hand to the companies with its Meros Technology for engineering off-gas cleaning system in an environmental friendly approach.
Siemens Metals Technologies, world’s leading life cycle partners for metals industry has received an order from Karabuk Demir Celik Sanayi ve Ticaret A.S. (Kardemir) for supply of basic components required to clean the off-gases from its new sinter plant No. 3. Kardemir, also titled as “The Factory Constructs Factories” is a Turkey based steel producer.
Siemens Metals as per the order needs to manufacture the entire off-gas cleaning system and supply the first and final cleaning stages. The cleaning stages should be based on Meros Technology, which is capable of reducing dust, acid gases and harmful metallic and organic components in the sinter off-gases. These types of attainments were earlier not possible with the conventional gas-treatment technologies. In addition the Meros Technology is environment friendly as SO2 emissions are significantly lowered. Furthermore, the gas cleaning system will be able to clean around 0.4 million standard cubic meters of off-gas in an hour. It is likely to be in operations by the end of 2014.
Kardemir is also planning of expanding its Karabuk production location including the construction of its new sinter plant No. 3. Siemens has supplied the company earlier in 2012 with Merim dry dedusting system for its new blast furnace which will soon be in operations. Kardemir opted for Siemens for product supply yet again in order to gain benefits of its new technologies of reduced sulfur emissions.
Siemens will look after the entire plant and supply of machinery for the cleaning stages to Kardemir. The cleaning stages will involve in its first step, a cyclone separator to remove the dust from the off-gas flow. The dust will then be recycled in the sinter production to minimize the loss of Iron ore particles present in it. In the next step, Meros technology will be used to inject and equally distribute adsorption and desulfurizing agents into the off-gas flow. In addition, Kardemir will use hydrative lime for desulfurization in order to reduce sulfur dioxide emission by about 85 percent.
The company will design the innovative system so that it can be further utilized to remove nitrogen oxides, dioxins and volatile organic compounds during operations in future.
