· Designing Iron Sponge Process For H2S Removal posted in Student: Hi all, I am a final year student in australia and am trying to complete my design project. I am tasked with designing the equipment for the Iron Sponge (oxide) process for the removal of hydrogen sulphide from natural gas. I have come to understand that this is a fixed bed adsorber column .
· Sponge Iron production usually employs the DRI Process, undertaking solidstate reduction of hematite ores with equal proportions of coal. This is brought about by the use of a coalfired Rotary Kiln, with the environmental impact of the entire process putting Sponge Iron plants under 'Red Category' industries. These industries generally have a high pollution .
Sponge iron making process SlideShare The feed is introduced together with reducing and desulphurizing agents (limestone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge . 8200/ per ton. present in sponge iron/DRI, HBI and cold briquettes.
Reduced Iron Powder is usually produced by reducing the oxide part (such as iron ore, rolled steel scales, etc...) which by using of solid or gaseous reducer (such as coke, charcoal, anthracite, water gas, reformed natural gas, ammonia or hydrogen decomposition) to generate the sponge iron. The reduction process consists of two procedures, which
· Midrex process is simple to operate and involves three major unit operations namely (i) iron ore reduction, (ii) gas preheating, and (iii) natural gas reforming. The heart of the Midrex process is its shaft furnace. It is a cylindrical, refractorylined vessel and is a key component of the direct reduction process. It is flexible as well as a versatile reactor. It can .

Sponge iron is the residue left after iron ore is reduced directly to metallic iron. This process of manufacturing is done with the help of carbon like charcoal, etc. This process is fabried at temperatures lower than the melting point of iron. The result is a spongy mass with a composition of incandescent wrought iron and slag. The final product is primarily used in the making of .

Process for production of sponge iron by direct reduction of iron ore wherein iron ore admixed with a carbonaceous reducing agent is passed through a rotary kiln countercurrent to a gas stream, and wherein granular coking high volatile coal is injected cocurrent to said gas stream as a solid reducing agent by means of oxygen containing gases through an inlet pipe, and said .
In this study, debromination of BDE 209 with sponge iron, also called directreduced iron, was studied to investigate the degradation process and .
Sponge iron production process requires accurate monitoring and control of the process parameters. The performance of rotary kiln sponge iron based processes is normally affected by accretion build up along the kiln linings. Accretion build up is the accumulation of semimolten material which form rings along kiln lining. These rings narrow the kiln diameter thereby .
Sponge iron making is a process in which iron ore lumps (typically 5mm18mm size) are tumbled with a 'select' grade of ironcoking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished product bunkers prior to dispatch.
