  • H2S Dry Scrubber Technology | Proven Design | Enhanced Media

     · In the primary reaction, H 2 S in the inlet gas stream reacts with the oxide Fe x O y in the media to form fur compounds Fe x O y, free sulfur and water. Oxygen present in the gas stream further reacts with the compound liberating the sulfur and re-forming the oxide, making it available once again for the primary reaction

  • Biochar in the Höganäs sponge iron process – techno

    the Pettersson et al. 2016. Experiments with utilizing biochar as a reducing agent for the have been performed at Höganäs, and results have shown that it is possible to use blends with biomass based biochar in their reduction mix, replacing some of the fossil reduction agents. However, for evaluation

    The sulpha compound has Fe 2 /Fe 3 cores forming interstatially stabilized clusters. The invention also includes a for desulphurising natural gas by adsorbing sulphur containing contaminants in the novel sulpha compound either

  • difference between sponge iron and pellets - BINQ Mining

    What is a different between Ore Pellet and …. Jun 20, 2006 · Best Answer: is the product created when ore is reduced to metallic , usually with some kind of


    In the year 1908 use of tunnel started for oxide reduction. This was invented by E.Sieurin as Hoganas process [3]. In 1954, more kilns came in operation in SWEDEN and USA. Presently it is more popular in China for production from beneficiated ore fines cakes. In this the material passes through

  • Simulation of Rotary Kiln Used in Sponge Iron Process

    ore to oxide which further reacts with CO to produce metallic Fe which is called . These two reactions are exothermic in nature. Thus, overall is exothermic. Fe2O3+CO = 2FeO+CO2 1 FeO+CO = Fe+CO2 2 In the four combustion reactions are involved amongst which first reaction Eq.3 is endothermic and


    "Longest campaign life of 550 days achieved at DRI kiln no 3 of M/s Usha Martin Ltd,Jamshedpur on 30th May 2012.The kiln is still running at rated capacity based on OSIL using ore having Fe:59% TI 72% and coal having Fc 35%.This is the longest campaign ever achieved by any coal based DRI Kiln."

  • Direct reduced iron

     · Direct , also called is produced from the direct reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state which reduce iron oxides to metallic iron at temperatures below the melting point of iron. derives its name from these

  • Ironmaking Process - an overview | ScienceDirect Topics

     · The ironmaking in the blast furnace is a heat and mass transfer , and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13].Corresponding to each temperature interval, typical reactions will take place
