Since 1969, Midrex and its partners have built (or are constructing) 72 MIDREX® Modules (shaft furnaces plus
reformers and associated systems) in 21 countries. To date, these facilities have produced 590 million tons (Mt) of
DRI and HBI. This record of plant sales, successful start-ups, and continued outstanding performance has resulted in
a market share for MIDREX® Technology of 50 percent or more each year since 1984.
The success of the MIDREX® Direct Reduction Process is based on the firm foundation of the work done by Donald
Beggs and his colleagues in the Surface Combustion Division of the Midland-Ross Corporation in the 1960s. Beggs'
concept of pairing a stoichiometric CO2 reformer with a shaft furnace to reduce iron oxide was brilliant, a once-in-alifetime
achievement. The MIDREX Process concept has stood the test of time and produced 40 million tons of iron
in 2008, trailing only the blast furnace.
MIDREX direct reduction ironmaking (hereinafter
referred to as the MIDREX process) reduces iron
ore using natural gas. The original process was
developed by the Midland-Ross Co., which later
became MIDREX Technologies, Inc. (hereinafter
referred to as MIDREX Technologies), a wholly
owned subsidary of Kobe Steel. A pilot plant was
built in Toledo, Ohio in 1967. The first commercial
plant, having a production capacity of 150 thousand
tonnes/year, was built in Portland, Oregon, in 1969.
The process was immature in 1978, when Kobe
Steel began the construction of a plant with a
production capacity of 400 thousand tonnes/year in
the State of Qatar. Kobe Steel significantly modified
the design, exploiting the company's technologies
developed through blast furnace operation, and
stabilized the then new process. On the other hand,
MIDREX Technologies also carried out various
improvements to the plants they built in various
countries. These were all integrated in the early
1980s, making the process nearly complete 1).
The maximum production capacity in 1984, when
Kobe Steel became affiliated with MIDREX
Technologies, was 600 thousand tonnes/year. Later
improvements, made by Kobe Steel in collaboration
with MIDREX Technologies, have dramatically
increased the production capacity. In 2007, the scale
reached 1.8 million tonnes/year, which is comparable
to that of a small blast furnace.
What else can I help you with?
Is iron sulphide reversible or irreversible?
Iron sulfide is a chemical compound. A process or reaction may be reversible or irreversible; a compound isn't.
What type of material does a Cooper work with?
Coopers worked with wood and iron making barrels.
What is a process in which molten metal is poured into a mold and allowed to harden?
This process is known as casting. Iron in particular is often cast to make objects.
What is iron refined from?
In short, the iron ore hematite (Fe2O3). Iron is a raw material and you technically don't need to refine anything to get it. But because iron oxidizes (rusts) in the presence of oxygen, the iron ore must be heated and melted to remove the oxygen. During the process, the iron is usually mixed with carbon to increase it's strength. The end result is steel.
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
What is the process for producing sponge iron in coal based rotary kiln process quantitatively?

Can sponge iron making is a primary metallurgical process - yes or no?
Yes, sponge iron making is a primary or can be a primar metallurgical process base on the Chemistry information that is provided.
What two chemicals can reduce iron ore to iron?
Carbon monoxide and hydrogen are typically used in the reduction process of iron ore, where they react with the iron oxide to produce metallic iron. This process is commonly known as the direct reduction process or the Midrex process.
How do you calculate the yield of production of sponge iron?
The yield of production of sponge iron is calculated by dividing the weight of sponge iron produced by the total weight of iron ore initially taken for the process, and then multiplying by 100 to get the percentage yield. It is important to consider losses during the process to get an accurate yield calculation.
Is propane used as feedstock for sponge iron?
No, propane is not typically used as a feedstock for producing sponge iron. The most commonly used feedstock for sponge iron production is natural gas or coal. These feedstocks provide the necessary carbon and heat required for the direct reduction process to convert iron ore into sponge iron.
What is the difference between continuous distillation and batch distillation in chamistry?
sponge iron production is continuous process sponge iron production is continuous process
What are the parameters that must be comtrolled in midrex process?
In the MIDREX process, parameters that must be controlled include the flow rates of natural gas and recycled gas, the temperature within the reduction shaft to ensure proper iron ore reduction, and the level of reducing gas (typically hydrogen and carbon monoxide) to maintain the desired reaction kinetics and product quality. Monitoring and controlling these parameters are crucial for efficient and effective direct reduced iron (DRI) production.
What is the difference between Sponge iron and pig iron and their application?
Sponge iron is produced by reducing iron ore pellets in a direct-reduction process, whereas pig iron is produced by melting iron ore with a high-carbon fuel in a blast furnace. Sponge iron is mainly used as a raw material for steelmaking in electric arc furnaces, whereas pig iron is typically used in the production of cast iron and wrought iron products.
How do you found Fe total of sponge iron?
Measuring the mass of sponge iron.
Chemical reactions in sponge iron production?
In sponge iron production, the chemical reactions typically involve reduction of iron oxide (Fe2O3 or Fe3O4) using a reducing agent such as carbon monoxide (CO) or hydrogen (H2) in a direct reduction process. The reduction reactions result in the formation of sponge iron (Fe) and carbon dioxide (CO2) or water (H2O) as byproducts. The overall process is aimed at producing high-purity iron for steelmaking.
What is the relation between metallic iron and total iron in sponge iron?
Metallic iron refers specifically to the iron that is in its metallic form in sponge iron. Total iron in sponge iron includes metallic iron as well as any iron present in other forms such as iron oxides. Therefore, metallic iron is a subset of total iron in sponge iron.
