Iron Sponge Process - an overview ScienceDirect Topics

The advantages of the iron sponge process include: (1) providing complete removal of small to medium concentrations of hydrogen sulfide without removing carbon dioxide, (2) requiring relatively small investment, for small to moderate gas volumes, compared with other processes, (3) being equally effective at any operating pressure, and (4) being used to remove mercaptan derivatives or convert ...

Sponge Iron - an overview ScienceDirect Topics

The process involves heating the naturally occurring iron oxide in the presence of carbon, which produces “ sponge iron.” In this process, the oxygen is removed without melting the ore. Iron oxide ores extracted from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction reaction, as the iron ore is heated with carbon, it results in a pop-marked surface ...

In the process, iron ore fines limestone are pre-heated by the off-gases of the smelting chamber in a rotary kiln, to temperatures of 900-1,000°C then hot-charged into the MAGMA chamber. Coal is directly burnt in oxygen inside MAGMA. The liquid-sodium cooling system adopted in MAGMA maintains the temperature of the body of the smelting chamber at around 500°C. This helps to reach very ...

Difference Between Sponge Iron and Pig Iron Compare

30/04/2011  Sponge iron has many advantages over other similarly smelted iron forms. Sponge iron is superior to pig iron as it is richer in iron content. Because of this property, it has many uses in electric furnaces. We can mix sponge iron, in its powdered form with many other metals to manufacture a variety of iron-containing products. Figure 01: Iron Bloom (sponge is a Bloomery Product) For instance ...

Iron And Steel Industry In India: An Overview

Industrial fans are used in the production process of iron and steel extensively. Before coming to that, you should know that the manufacturing process of steel involves two ways. Coal, iron ore and limestone are put into the blast furnace to produce the materials. Alternatively, existing scrap of steel can also be used to produce fresh steel in electric arc furnaces. In both these processes ...

OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION IN A

Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron. Depending on its content of volatile matter, the coal is part-ly blown into the ...
