Desulfurization

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
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.

a leading Spanish heavy machinery manufacturer, have jointly received orders in succession for large-scale flue gas desulfurization (FGD) systems, four units in total, from two major Spanish electricity providers: Iberdrola Generacion, SAU and Endesa Generacion, SA.
Holliday Pigments has invested over $30 million in flue gas desulfurization plants at its production sites in Hull and Comines, France, which has resulted in a "massive reduction" of sulfur dioxide emissions inherent in the manufacturing process.
It must be emphasized that desulfurization processes are also essential for the production of fuel oil from oil shale and for oil obtained by the utilization of used tires.
