Sponge Iron Production Process - Arij Trading

Market share: About 23% of sponge iron total production. 4) Tunnel furnace process . This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent. Natural gas generates the required reduction temperature, and reduction is performed on Silicon Carbide (SiC) Crucibles in a tunnel furnace.

Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example bein…

Iron Sponge Process - an overview | ScienceDirect Topics

Maurice I. Stewart Jr. PhD, PE, in Surface Production Operations (Third Edition), Volume 2, 2014. 9.4.2.1 Application. The iron sponge process is economically applied to gases containing small amounts of H 2 S (< 300 ppm) operating at low to moderate pressures in the range of 50-500 psig (344.7-3447 kPa). This process does not remove CO 2.

Sponge Iron - an overview | ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

Iron Sponge Process | Oil and Gas Separator
