Chapter 5, Production and Use of Industrial Gases for Iron ...

2010-9-29  Hydrogen is used in significant quantities for natural gas based production of direct reduced iron(DRI). In the Midrex process, the CO2and H2O which is present in the offgas from the directreduction shaft reactor is used to reform natural gas and produce the high temperature H2and COcontaining reducing gas required to achieve the desired level of iron ore conversion to iron. InHylsa's HYL III process, a conventional steam reformer is used to produce the reducing gas, andthe CO2and H2O in the reactor offgas is removed to allow recycle of unreacted H2and CO backinto the reactor. The natural gas consumption is approximately 11,000 scf per ton of DRI, and thereducing gas

Iron Ore - an overview ScienceDirect Topics

In a blast furnace, coke is used to reduce the ore (iron oxide) to iron. Large quantities of gas, “top gas,” are formed at the top of the blast furnace as a result of the reduction of iron ore and the combustion of injected coal by injected blast air. Gas analysis is used to optimize the blast furnace process, including reducing the consumption rate of coke and controlling the temperatures inside the furnace.

Hydrogen gas and its use in Iron and Steel industry ...

2019-1-14  Hydrogen reduction processes There are several hydrogen reduction processes for the iron ore as described below. Shaft furnaces are used for the reduction of iron ore pallets with reformed natural gas which is a mixture of hydrogen and carbon mono oxide. The two most relevant direct reduction processes are Midrex and Energiron (HyL-III).

One order of steel; hold the greenhouse gases MIT

2013-5-8  Sadoway found that a process called molten oxide electrolysis could use iron oxide from the lunar soil to make oxygen in abundance, with no special chemistry. He tested the process using lunar-like soil from Meteor Crater in Arizona — which contains iron oxide from an asteroid impact thousands of years ago — finding that it produced steel as a byproduct.

Direct Reduction of Iron Ore with Green Hydrogen

2020-2-9  Direct reduction of iron ore refers to the conversion of solid iron ore to metallic iron without conversion to the liquid phase [37]. Majority of the direct reduced iron (DRI) [38] is produced by reacting iron oxide with hydrocarbon-based reducing gases produced from reforming natural gas or coal gasification [39–42].
