Desulphurization. Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule (e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as oil refinery streams.These processes are of great industrial and environmental importance …

Torpedo desulphurization – Initially (in the 1960s and 1970s) hot metal desulphurization took place in the torpedo cars which transported the hot metal from the BF to the steel melting shop. Typical reagents used were calcium carbide, soda ash, and blends of magnesium and lime. During torpedo desulphurization, the reagent is injected into the ...

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.

Desulfurization can be understood as an electrochemical exchange reaction, where sulfur receives two electrons and turns to sulfide anion. The electrons are obtained from "free" oxygen ions in the slag; O-atoms are generated and transferred to steel as dissolved oxygen which can further react with a deoxidizing component like aluminum:
