Sponge iron (SI) is a promising material for nitrogen removal from wastewater. This study reveals the potential functions and mechanisms of SI-mediated multiple metabolic processes in the nitrogen removal of Anammox.
With such dimension of notion WE in our Sponge Iron Manufacturing process through 4 Kilns (1 * 350T and 3 * 500T) laid up the best DRI making process in India. It is Coal Fuel based DRI.
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
This commitment is evident in our Sponge Iron Manufacturing process, specifically in the MIDREX Kiln, showcasing the best DRI making process in Iran. Notably, our process is Gas based, and for more information on our coal-based sponge iron process, you can read further about Romak DRI Sponge Iron.

Following are the types of WHR technologies that are working in the sponge iron and steel re-rolling units for recovery of waste heat and power generation from the waste heat thus received in the process itself.
Semantic Scholar extracted view of "Profitability analysis of power generation using waste heat of sponge iron process" by G. Gaurav et al.
During this process, the mixture of magnetite ore, coke, and lime is placed in a silicon carbide retort. Heating this retort in kiln results in an iron cake and a slag. Later, the iron sponge is separated from this slag for crushing and annealing to turn it …
The Sponge Iron Process (SIR) is a well-known technology for the production and purification of hydrogen. It consists of a cyclic process in which a feed gas, rich in carbon monoxide and hydrogen (e.g. syngas), is passed on an iron oxide (magnetite Fe3O4) at high temperature. Magnetite is reduced to wuestite (FeO) or iron while carbon …

The cement production process was implemented in AspenPlus® environment, simulating different scenarios with the possibility to conduct the non recyclable plastic waste incineration in oxy-combustion conditions. ... 2D CFD model of rotary kiln of sponge iron process is developed to study the effects of angle of inclination, number of …
An effective thermal conductivity was used for defining the degree of mixing in the bed region, which helped in visualizing the process effectively. Their results provided only the qualitative information of the process [8]. Prasad and Ray simulated flow pattern of air using FLUENT software in rotary kiln of a typical 100 tpd sponge iron.
MakingRaw materials of sponge iron making:The basic raw mat. are iron ore, coal and flux.A) Iron Ore: It is very much important raw materi. l which is required for making sponge iron. The important iron ore is hematite(Fe2o. ). This ore is used for sponge iron making. While selecting iron ore for sponge iron m.
Sponge iron means porous iron produced by direct reduction process. Direct reduction (DR) process is a solid-state reaction process (i.e. solid–solid or solid–gas reaction) by which removable oxygen is removed from the iron ore, using coal or reformed natural gas as reductants, below the melting and fusion point of the lump ore or …
Qualitative requirement of coal in both cement and sponge iron sectors are guided by Indian standards which have been summarized in Table 1 and Table 2 respectively.
DRI (Direct Reduced iron), commonly known as Sponge Iron, is a metallic product produced through the direct reduction of iron ore (in the form of lumps, pellets, or fines) in the solid state. It is a substitute for scrap and therefore is mostly applicable in making steel through the secondary route. Download Brochure.
A 2D CFD model of rotary kiln is developed using ANSYS 14.5 for sponge iron process. The present study discusses the nature of temperature profile of the bed and gas(air) along the length of the ...
Sponge Iron:Today, sponge iron is produced by reducing iron ore without melting it. This makes for an energy-efficient feedstock for specialty steel manufacturers which used to rely upon scrap metal.
This paper presents an approach to find the best modification in the coal-based sponge iron process with an aim to integrate energy in it. For this purpose, a few energy conservation cases are formulated by integrating unutilized energy present in possible areas of process flow sheet. When unutilized energy of the process is properly …
