Abstract

Sulfur estimation in COAL/COKE, LIME/DOLIME is very important in Iron&Steelmaking process. Conventionally it is estimated byGravimetric and Combustionmethods.Anew&rapid semi instrumentalmethod is developed and also cost effective compared to other expensive analytical instrumental techniques. This method of Sulfur estimation is also applicable to Limestone, Dolomite and Ladle Furnace (LF) Slag also.
