Midrex hbi plant: corpus christi, texas, U.S.A. VP of Direct Reduction …

Direct reduction (DR) with natural gas as the reducing agent, already an industrially applied technology, is such an alternative. Consequently, the melting behavior of its intermediate product, i.e., direct reduced iron (DRI), in either an electric arc furnace (EAF) or a submerged arc furnace (SAF), is of great interest.

The work proposes a perspective on the direct reduction of iron (DRI) using hydrogen. Typically, iron is produced in blast furnaces (BFI) by the reduction of iron ore with carbon-rich materials such as coal or coke. Greenhouse emissions may be drastically reduced by introducing DRI coal/oil-based, and further reduced by using methane …

In addition, direct reduced iron has a well-defined chemical composition when compared with steel scrap and has efficient melting properties in the electric arc furnace.

MetalTek is North America's leading supplier of centrifugally cast reformer tubes for the direct reduction of iron (DRI). DRI is the process of producing metallic iron by removing oxygen from iron ore without melting. During DRI reformer tubes produce hydrogen, which reacts with the iron ore inside a heated furnace and removes the oxygen. The process …

MIDREX is an innovative ironmaking process that has been specifically developed to produce direct – reduced iron from iron ores and natural gas/hydrogen. MIDREX is a gas-based shaft furnace process that converts iron oxides – in the form of pellets or lump ore – into direct-reduced iron (DRI).

Technologies that produce direct reduced iron (DRI) enable the industry to reduce emissions or even approach net-zero CO 2 emissions for steel production. Herein, comprehensive cradle-to-gate (CTG) life cycle analysis (LCA) and techno-economic analysis (TEA) are used to evaluate the CO 2 emissions of three DRI technologies.

"Direct reduced iron" (DRI) technology often uses methane gas to produce hydrogen and carbon monoxide, which are then used to turn iron ore into iron.

Hydrogen-based direct reducing iron production (H-DRI) possesses great potential for energy saving and emission reduction of greenhouse gas in metallurgical industries. Although the relevant research has been studied since long, the thermodynamics and process of reduction by pure H2 in a broad temperature range are not well …
