((a)-(b)-(c)/ The quantity of CO
2 reduced (d)) + Equipment cost + Other costs
where (a) is (the quantity of HBI charged × HBI unit price), (b) is (the quantity of iron ore reduced × iron ore unit price), and (c) is (the quantity of reductant reduced × reductant unit price).
Note: The value of (c) equals (the quantity of coke reduced × coke unit price) + (the quantity of pulverized coal reduced × pulverized coal unit price). The quantity of CO
2 reduced (d) equals (the quantity of reductant reduced × CO
2 emission factor).
The key technologies utilized for this achievement are:
(1) Technologies of Midrex for HBI manufacturing in the engineering business
Kobe Steel, Ltd. (KOBELCO) has successfully demonstrated technology that can reduce CO2 emissions from blast furnace operations by approximately 20% by combining the Midrex’ HBI technologies and the blast furnace operations of Kobe Steel. The demonstration test was conducted for a month at a large blast furnace (4,844 m3) of.
