Thermodynamics of desulphurization of liquid steel There are four aspects which are important during the desulphurization of liquid steel. These are (i) sulphide capacity, (ii) sulphur distribution ratio, (iii) desulphurization potential, and (iv) rate of desulphurization. Sulphide capacity – It is the ability of liquid slag to adsorb sulphur.
