Direct reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains elemental carbon (produced from natural gas or coal) and/or hydrogen. When hydrogen is used as the reducing gas no carbon dioxide is produced.
In the iron and steel industry, direct reduction is a set of processes for obtaining iron from iron ore, by reducing iron oxides without melting the metal. The resulting product is pre-reduced iron ore. Historically, direct reduction was used to obtain a mix of iron and slag called a bloom in a bloomery.
Process flowsheeting is the use of computer aids to perform steady-state heat and mass balancing, sizing and costing calculations for a chemical process.It is an essential and core component of process design.
The Corex Process is a smelting reduction process created by Primetals Technologies as a more environmentally friendly alternative to the blast furnace. [1] Presently, the majority of steel production is through the blast furnace which has to rely on coking coal [2] and requires a sinter plant in order to prepare the iron ore for reduction. [3]
