In Chapter 10, an outlook is given for the expected changes in the steel industry between now and 2050 and its impact on sulphur removal in iron- and steelmaking. The amount of carbon used to reduce iron ore will gradually decrease and so will the demand for HMD, as the carbon sources coal and coke are the largest source of sulphur in hot metal.

At the steel plants of SSAB in Sweden, the production is iron ore-based and the pellets used in the blast furnace are from LKAB. Thus, this implies a high content of titanium and vanadium compared to the other pellet types. Coke is used in the blast furnace to reduce iron ore and it is one of the major sources of sulfur coming to the hot metal.

Today, roughly two-thirds of the world's steel is produced via the integrated blast furnace-basic oxygen furnace (BF-BOF) route. In this process, iron ore is reduced mainly by coke in the blast furnace (BF). This coke also produces the required heat by reacting with the available oxygen (from the hot blast and the FeO). The liquid hot metal ...
