Achieving Carbon-free Emissions via the ENERGIRON DR Process

摘要

For more than 50 years Tenova HYL has developed technologies designed to improve DRI based steelmaking competitiveness and productivity. The recent alliance between Tenova HYL, Techint and Danieli brings a new brand - ENERGIRON - to the forefront of the direct reduction industry. The ENERGIRON process has been improved over generations and the current status of the technology, the ENERGIRON ZR (or Self-reforming) Process, was developed to allow reduction of iron ores in a shaft reactor without external gas reforming equipment. This process scheme has the ability to produce high carbon DRI, which allows producers to obtain maximum benefits of carbon in the steel making process while producing a product of higher stability. The HYTEMP~? System developed to transport hot, high carbon DRI directly to the EAF meltshop, has been successfully operating since 1998, now in full operation in the 1.6 million t/y Emirates Steel plant in Abu Dhabi, continuously transporting more than 200 t/h of hot DRI to the meltshop. The ultimate objective has been the optimization of overall energy consumption, with the implicit reduction of CO_2 emissions.
