desulfurization

[dē‚səl·fə·rə′zā·shən]
(chemical engineering)
The removal of sulfur, as from molten metals or petroleum oil.

Desulfurization

 

a combination of physicochemical processes that promote the removal of sulfur from molten metal (cast iron, steel). It consists in converting the sulfur dissolved in the metal to sulfides that are either insoluble or poorly soluble in the liquid metal bath (for example, MnS, MgS , CaS, and Na2S). Examples of desulfurizers are lime, sodium carbonate, and metallic magnesium.
