| From STEEL GRIPS online Middle East Emirates Steel boosts green profile Nov 25, 2009
Two new direct reduction plants at Emirates Steel will allow Emirates Steel to commercialize the CO 2, which is considered a by-product of the DR plant. The selective elimination of CO 2 from the process off gas stream is an integral system and an inherent feature of the Energiron DR technology for optimization of the use of reducing gases and energy consumption. This DR process, which includes the selective capture of CO 2 emissions, will make the new Emirates Steel plant in Abu Dhabi among the world’s “greenest” steel mills. Tenova HYL and Danieli & C., currently have two plants underway at the Emirates Steel complex in Mussafah, Abu Dhabi, UAE. The first plant, which is now operating, is a 1.6 million t/a Energiron plant designed to feed the 1.4 million t/a steel plant with hot DRI. The second plant, a mirror image of the first and part of a duplicate turnkey steelmaking installation, is scheduled to be put into operation during late 2011. Emirates Steel has been very conscious of its role in redefining steelmaking in the Gulf region, and a key aspect of this will be in the capture and reuse of CO 2 emissions from the DR plant. A first of its type in the region, the Energiron plant uses a chemical absorption system to allow the selective removal and capture of up to 50% of the total CO 2 generated by the reduction process. In the case of Emirates Steel, this CO 2 will be compressed and then pumped into oil wells instead of natural gas to boost oil production. The Ternium plant in Monterrey, Mexico, the Ternium plant in Puebla, Mexico and the Welspun Maxsteel plant in India are all operating under this scheme, with the CO 2 being captured, cleaned and sold to local gas producers for resale to the beverage industry. The only Energiron DR plant which was still operating under the original process scheme (without CO 2 absorption), ArcelorMittal, has also recently included CO 2 removal technology at their 2 million t/a HYL plant in Lazaro Cardenas, Mexico. Emirates Steel expects to be able to commercialize at least 25% of the CO 2 which would otherwise be emitted to the atmosphere. © Copyright 2007 by GRIPS media |
