Study of Coke-oven Gas Desulphurization and Methods to Improve Sulphur Quality
Abstract: The coke-oven gas has high calorific value and can be used for the burning process. The coke-oven gas coming out from the coke-oven department contains impurities like Sulphur, Ammonia, Tar, and Naphthalene. Sulphur is the major impurity; it is very harmful and poisonous to the environment. So the removal of sulphur plays an important role in the purification of coke-oven gas. The sulphur extraction can be done by absorption using …

Efficient Conversion of Sponge Iron from Iron Ore-Coal Composite
Abstract: Today India stands as the largest producer of coal based sponge iron using calibrated ore and non-coking coal. Production of sponge iron, via the direct reduction route using rotary kilns, continues to experience significant growth in India. Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. …
