Whether you're preceda self serve moving really something to reduce pollution of 'Ilva Taranto? We learn through a press release from Siemens announces that it has been awarded, through its Business Unit Metals Technologie, preceda self serve the 'order for the supply of four Meros turnkey plants for the two lines of agglomeration preceda self serve steelworks in Taranto preceda self serve Ilva SpA.
This system, they explain, will contribute preceda self serve to the improvement of environmental conditions in the area of Taranto as "the process developed by Siemens Meros help reduce harmful emissions generated by the agglomeration process by treating more than 2.6 million cubic meters of exhaust fumes per hour per line, thereby preceda self serve reducing emissions of sulfur dioxide, particulate matter, volatile organic compounds, acid gases and heavy metals at levels significantly below the current limits of Europe '.
What time? The commissioning of the first two plants is scheduled for April 2015, one of the two remaining for September of 2016. The order, explain, has a two-digit millions of euros. An investment certainly not conclusive, but it gives some glimmer of hope that they are trying to improve a situation to say the least heavy. As is well known in our opinion the closure of Ilva, as understandable as fit of rage for the damage done to the environment and to people, it would not be conclusive, but potentially even worse because it would make it almost impossible to clean up the areas, in addition to opening a huge social problem in a complicated phase. We do not have a solution in hand, but make the system preceda self serve "sustainable" and convert that back to rehabilitating the area remains in our humble opinion the best option. Riva on the payers of course, with the minimum state contribution on the control of the work done.
Prejudice to the treatment plants, Siemens points out that thanks to them "in the future preceda self serve emissions of particulate matter by the fireplace will be more than 1,000 tons of what was allowed by the previous emission limit of 40 mg / Nm 3. In addition, emissions of dioxins will be reduced by approximately 12 g / year, the current emission limit of 0.4 ng I-TEQ/Nm 3, less than 3 g / year. The system also allows the reduction of sulfur dioxide emissions. " preceda self serve
The steelmaker Ilva Taranto, owned by the Riva Group, with an annual production preceda self serve of over eleven preceda self serve million tonnes steel plant is the largest in Europe and it comes about 30% of the steel used in Italy. Both sinter plants, already modernized and expanded by Siemens in 2001, are capable of producing up to eleven million tons of sinter per year.
The plants Meros replace the obsolete electrostatic precipitators MEEP, only able to remove dust. The installation and integration of new units within the exhaust system of sinter preceda self serve plants will take place during the exercise of the latter, thus making it necessary only short stops. The process involves the injection Meros and accurate distribution of adsorbents and desulphurising, such activated carbon and sodium bicarbonate, within the flow of exhaust fumes, tying and effectively removing heavy metals, organic components harmful and dangerous, sulfur dioxide and other acid gases. The use of sodium bicarbonate preceda self serve for the reduction of the percentage of sulfur dioxide, in addition, does not require preceda self serve the presence of a reactor. The process does not involve the use of water, thus avoiding leakage of steam from the chimneys.
The dust particles are deposited in a bag filter specially developed, efficient from the point of view of energy, suitable for temperatures up to 250 C and at very low pressures during the cleaning process. The bulk of the dust removed from the precipitator is recirculated within the flow of exhaust fumes to further optimize the efficiency and economic benefit produced by the process of flue gas cleaning. All additives remaining unused come again into contact with the exhaust fumes so as to be almost fully exploited. The use of sodium bicarbonate in place of calcium preceda self serve hydroxide allows to reduce considerably the residue downloaded. The automation system of the process ensures a stable operation preceda self serve even in case of considerable fluctuations in the volume and composition of the exhaust fumes, or consentend therefore always to observe the emission limits.
