Iron sponge (Iron Oxide) Iron sponge consists of wood chips that have been impregnated with a hydrated form of iron oxide. The material is placed in a pressure vessel through which the sour gas is flowed. Because this is a batch process, usually two vessels are installed—one in service and the other on standby.

Sponge Iron, also known as Direct Reduced Iron is produced from Hematite Iron ore (5 to 18 mm size) by removing the oxygen by direct reduction process using non …
8.5.1 Iron sponge process. An example of a hydrogen sulfide scavenger process is the iron sponge process (also called the dry box process), which is the oldest and still the most widely used batch process for sweetening of natural gas and natural gas liquids (Anerousis and Whitman, 1984). The process was implemented during the 19th century …
Technology. India is the world's largest Sponge Iron producer and mostly uses the Coal based process. The down-side of this industry is that it generates significant amounts of solid waste in the form of ESP Flyash and Bag House Filter Dust. Now as this Flyash contains considerable unburned carbon ( 10% and above), it cannot be utilized in ...
The process of sponge iron involves the removal of oxygen from iron ore. During this process, the departing oxygen causes micro pores in the ore body making it porous. The final product, when observed under a microscope, resembles a honeycomb structure looking spongy in texture, hence the name sponge iron.
Sponge iron is the product created when iron ore is reduced to metallic iron, in the presence of coal, at temperatures below the melting point of iron. The external shape of the ore is retained with 30% reduction in weight due to oxide reduction resulting in change in true density from 4.4 gm/cc to 7.8 gm/cc in this product
Sponge iron, also called direct reduced iron (DRI), is made from directly changing iron ore (in any form whatsoever) to iron by a cutback gas or carbon, produced from natural gas or coal. It is one of the many raw materials used in sponge iron. Specifications WHY IS IT CALLED SPONGE IRON? Iron oxide ores taken out from the Earth are allowed to absorb
Initial investment of Rs 7-12 crores on a 100 tpd sponge iron plant, can be recovered within just 12-18 months. • For every 100 tpd of sponge iron produced, the consumptions are: • 160-175 tonnes of iron ore, • 120-150 tonnes of coal, • 3.5-5 tonnes of dolomite and • 2.0-2.2 tonnes of water.
