Natural gas – the cleanest, greenest ironmaking fuel. Midrex NG is the most widely-used technology for the production of all forms of direct reduced iron (DRI) products because they are known for their reliability and hours of continuous operation. Each year, MIDREX® Plants produce more than 60% of the entire world’s DRI and more than 80% of the DRI produced by all shaft furnace technologies.
Natural gas is playing a major factor in helping many industries cut emissions and improve the world’s overall air quality. To use natural gas for ironmaking, the natural gas needs to be processed, or rather, reformed into a usable reducing gas that is high in hydrogen (H₂) and carbon monoxide (CO) content.
MIDREX NG™, through use of the patented MIDREX® Reformer, cost effectively makes reducing gas for the iron ore reduction reactions that take place in the MIDREX® Shaft Furnace. The MIDREX® Reformer externally generates reducing gas and further optimizes the MIDREX Shaft Furnace performance by converting recycled gas (from the iron reduction reactions) along with fresh natural gas into H₂ and CO to produce additional reducing gas.
The MIDREX Reformer has been at the core of the MIDREX Process since its inception.
- Reformer reforms both CO₂ and H₂O with natural gas, thus eliminating the need for an expensive CO₂ removal system
- Generates low H₂ / CO ratio reducing gas- resulting in better energy efficiency
- Valuable heat is retained from the MIDREX® Reformer eliminating the requirement of an expensive gas heater
