Pig Iron Manufacturing Emissions

The reduction of iron ore (Fe 2 O 3) to pig iron, directly with coke (Eq. 1) produces CO 2 emissions related to the reaction. The specific emissions related to the reduction reaction of iron are typically 588 kg CO2 /t pig iron [25]. The reducing agents also react with the oxygen to produce carbon monoxide which is later converted to carbon ...

Iron and steel manufacturing from both primary and secondary sources continues to be an essential enabler for a strong domestic economy. Primary iron production is dominated by integrated steel mills, which use a blast furnace to convert coke and iron ore into pig iron; the pig iron is then purified in a basic oxygen furnace (BOF) to make steel.

Sponge iron is considered more environmentally friendly due to its lower energy requirements and lower carbon emissions compared to pig iron production, which is energy-intensive and has higher carbon emissions. ... Also known as direct reduced iron, used in steel manufacturing. Many steel plants use sponge iron as a raw material. 13.
