Desulphurisation - an overview | ScienceDirect Topics

Figure 2.27 shows the desulphurization possible for iron compositions and temperatures typical of basic practice if C–O equilibrium is achieved and if Si–O equilibrium occurs. The calculations assume a heterogeneous 5% A1 2 O 3 slag, a 0.75 wt% S level in the coke and weight ratios of iron, coke and slag of 10:1.8:1 respectively.
