Reducing Gas - Natural Gas
Midrex has a wide range of options to generate reducing gas for DRI production. When natural gas is the energy source, the choices include the standard MIDREX® Reformer and a steam reformer. With the MIDREX Reformer, OXY+® can be used to generate additional reducing gas.

MIDREX® Reformer
In 1969, Midrex designed and built the world’s first commercial high temperature, near stoichiometric CO2 reformer. This concept enables the production of a high quality reformed gas that can be fed directly to the direct reduction shaft furnace. The MIDREX Reformer converts recycled offgas from the Shaft Furnace plus fresh natural gas into hydrogen and carbon monoxide. The use of recycled gas and the ability to feed hot reformed gas to the shaft furnace without quenching and reheating provide for a very efficient process.
For over 40 years, Midrex has supplied more than 70 MIDREX Reformers for projects around the world. The largest MIDREX Reformers can produce nearly 450,000 Nm3/hr of reducing gas, enabling the production of 2.5 million tons per year of DRI. Even larger units are being considered.

Steam Reformer
MIDREX Plants can incorporate a conventional steam reformer as used in the petro-chemical industry. One such example is the FMO Planta de Briquetas (formerly OPCO) in Puerto Ordaz, Venezuela. This MIDREX Plant started up in 1990 and still operates using the steam reformer originally supplied for another technology.
