STATUS OF SPONGE IRON UNITSIN ORISSAPrepared by –Environment Conservation Team(Aruna Murthy, Himansu Sekhar Patra)September 2005<strong>Vasundhara</strong>, E-14, Gajapati Nagar,Bhubaneshwar


STATUS OF SPONGE IRON UNITS IN ORISSAINTRODUCTIONSteel market in <strong>In</strong>dia is in a rising phase as infrastructure development has been rightly given highpriority. The secondary sector of steel production has witnessed phenomenal growth in recent years.The steel production through the secondary sectors, which works only 21.39% in 1993-94, has goneup to 35.46% in the year 2001-02. The reasons are:1. Low investment2. Ability to produce quality steel economically through this process3. Availability of <strong>Sponge</strong> <strong>Iron</strong> both in quality and quantity, which is a major raw material forsecondary steel makers.<strong>In</strong> the secondary sector, the steel production is mainly by EAF and induction furnace. <strong>In</strong>ductionfurnace route is gaining importance due to low investment cost and ability to produce quality steelat lower cost. A number of induction furnace units have been established with varied productioncapacity. With the increasing demand of sponge iron as the major raw material for the secondarysteel makers, there is mushrooming growth of sponge iron units in the country, particularly in theeastern side. All of them have opted for coal based plants having rotary kilns.The process of sponge iron making aims to remove oxygen from iron ore. When that occurs, thedeparting oxygen causes micro pores in the ore body making it porous. The final product, whenobserved under a microscope, resembles a honey comb structure, looking spongy in texture, hence,the name “<strong>Sponge</strong> <strong>Iron</strong>”RAW MATERIALS REQUIRED<strong>Sponge</strong> <strong>Iron</strong> manufacture is highly sensitive to raw material characteristics. Therefore, it is essentialto examine the chemical and physical characteristics of raw materials, both individually and incombination. The basic raw materials for the production of <strong>Sponge</strong> <strong>Iron</strong> are iron ore, non-cokingcoal, and dolomite.Coal: Important factors determining coal quality are:1. Chemical properties such as fixed carbon, ash-content, volatile material, etc.2. Physical properties such as reactivity, and ash-fusion temperature.


<strong>Iron</strong> Ore: <strong>In</strong> sponge <strong>Iron</strong> making, iron ore is reduced in solid state. Unlike in the conventional steelmelting process, the gangue content of iron ore cannot be separated as a slag. Therefore, it becomesimperative to select an iron ore with a high iron content and a low gangue content, to optimize yieldduring steel making. Apart from this, to ensure a better kiln campaign life and output, iron ore ismade to undergo a series of other tests such as – Shatter, tumbler and abrasion indices, reducibility,etc.Dolomite: It acts in the processes as a Desulphuriser removing sulphur from the feed mix duringthe reduction process. It is mixed in small proportion along with other raw materials beforecharging into the kiln.TECHNOLOGY INVOLVEDProduction of Steel through the conventional blast furnace requires coking coal of which <strong>In</strong>dia haslimited reserves. Therefore, evolution of a technology for the reduction of <strong>Iron</strong> Ore usingabundantly available non-coking coal was contemplated, giving birth to direct reduction <strong>Iron</strong>Technology (DRI).PROCESS


<strong>Iron</strong> ore (Hematite) and non-coking coal are the prime raw materials for the production of sponge<strong>Iron</strong>. These are charged into a rotary kiln in a requisite proportion along with some dolomite. Coalplays a dual role in the process by acting as a reductant as well as a fuel for providing heat tomaintain the requisite temperature inside the kiln at 950-1050°C. The reduction process occurs inthe solid state. The crucial factor in this reduction process is the controlled combustion of coal andits conversion to carbon monoxide to remove oxygen from the iron ore. The overall process requiresa duration of approximately 10-12 hrs inside the kiln, during which iron ore is optimally reducedand discharged to rotary cooler for cooling below 120°C, before coming out into the finishedproduct circuit.

ENVIRONMENTAL IMPACT OF SPONGE IRON UNITSRight from the raw material yard to disposal of the final product (<strong>Sponge</strong> <strong>Iron</strong>), at every step of itshandling there is pollution. <strong>Sponge</strong> <strong>Iron</strong> Plants have the following pollution hazards:1. Dust emission during raw material preparation and product discharge and handling:A definite size of iron ore and coal is required for the production of sponge iron. Thesuppliers are not adequately equipped to cater to the needs of the sponge iron industries.Therefore, the industries crush and size the raw materials at their plant premises. Duringsuch crushing and sizing operations, generation of fugitive dust and discarded ore fines andcoal fines in inevitable. Major dust emitting areas include areas such as product dischargefrom cooler to conveying system, magnetic separator, and raw material preparation unit.2. Reduction: The gaseous products of reduction contain mainly raw material dust, and gaseslike CO 2 , CO, H 2 , NO X , O 2 , unreacted hydrocarbons, and SO X3. Waste water discharge: The dusts from the gaseous emissions are separated through ESPor Gas quenching system. <strong>In</strong> either case, the disposal is done by converting the dust to aslurry form to avoid flying of the same in ambient air. <strong>In</strong> order to recycle the water, theslurry is allowed to settle in a clari-flocculator, from where the settled solid particles arepumped out. The polluted slurry water is then allowed to settle in settling ponds, or lagoonsfrom where the clear water is pumped back for reuse. Such water is polluted with dissolvedsolids.4. Gaseous emissions: The exhaust gas emerges out of DRI kilns at a temperature of about900°C having some quantities of combustibles. This gas is used to produce steam in wasteheat boilers, which in turn is used to produce power. The dust coming from exhaust gas iseither quenched to make slurry for easy disposal or is collected in dry condition or in wetcondition from the ESP. So far, no utilization of this dust have been found out which causesair pollution (due to dust) in the near by areas.5. Char: The partially burnt coal called char is discharged from the reactor along with spongeiron. After the magnetic separation, the char is separated as waste.PROBLEMS DUE TO SPONGE IRON UNITS IN ORISSA<strong>In</strong> many of the sponge <strong>Iron</strong> <strong>Units</strong> in <strong>Orissa</strong>, ESP has not been installed and where it is installed,these units switch off their ESPs during the nights for a few hours. Thus, the area becomes a hugesmoke bowl. <strong>In</strong> some sponge iron units in Sundergarh, it was found that the precipitators were notrunning in several of the units. Smoke and soot from the plants carried by the wind cause wheezingproblem in kids, and cows and cattle to become restless. The smoke is sometimes so thick thatvision even at a distance as close as 1 meter becomes difficult. The clothes worn by peopleimmediately become smeared with coal dust. Even cooking utensils are covered with soot. <strong>In</strong>Kormunda (Sundergarh) where Neepaz Metallics (a 1.4 lakh tonnes sponge iron plant) is set up, thedrinking water becomes covered with black soot. The emissions also cause irritation and wateringof eyes in human beings.


LEGISLATION, RULES AND REGULATIONS STIPULATED FOR SPONGEIRON UNITS IN ORISSAGovernment of <strong>Orissa</strong>, Forest and Environment Dept has stipulated the following regulations for theestablishment of sponge iron plants in the state of <strong>Orissa</strong>.A. <strong>In</strong> six sensitive blocks (Kuarmunda, Lathikata, Rajgangpur and Bonaigarh block ofSundergarh district, Jharsuguda Block of Jharsuguda District and Rengali block ofSambalpur district) including 25 Km from block boundary –‣ No new sponges iron & integrated steel plant will be allowed.‣ Cases which had been received by the state pollution control board before the Governmentdecided on a prohibition on establishment of sponge iron plants in the state may beconsidered individually un merit. These proposals can be considered on case to case basiswith the condition that they set up a WHRB with a Power plant within 1 year‣ Proposals of establishment of integrated steel plant where MOUs have already been signedwith the state government may be considered on merit‣ Expansion proposals received by the SPCB before the decision on prohibition onestablishment or expansion of sponge iron units was made by the government may beconsidered on merit within a condition to install WHRB and/or steel plant.‣ Expansion of existing plant will be allowed for 25/50 TPD to 100TPD for the purpose ofinstallation of WHRB and power plant.B. Outside the six sensitive zones‣ Cases which had been received by the state pollution control board before the governmentdecision on prohibition to establish sponge iron plant in the state may be considered. Theseproposals can be considered on case to case basis with the condition for installation ofWHRB power plant within 1 year.‣ Cases where MOUs have been signed with the State Government may be considered.‣ Cases other than the above 2 shall not be considered till an environmental impact study ofthe existing units as well as proposed units is done and it is examined by the SPCB inconsultation with steel and mines and industries department.‣ Expansion proposals of existing sponge iron units may be considered to facilitate installationof WHRB with CPP or expansion to integrated steel plant.‣ Proposal for integrated steel plants through DRI route may be considered by sSPCB on thebasis of merit.C. The pending cases (i.e. Proposals received before the Government’s decision on theprohibition on establishment of sponge iron) may be cleared with stipulation of installationof ESP, with separate energy meter, automatic change over to DG set and other pollutioncontrol measures as decided earlier or, recommended by the state pollution control board. <strong>In</strong>addition, explicit stipulation for installation of Waste Heat Recovery Boiler (WHRB) withCPP or upgradation of the unit to steel plant within a period of 1 year from the date of issueof the NOC shall also be made.D. The existing sponge iron units shall be required to install WHRB with CPP within 1 yearand take immediate steps for installing equipments for automatic changeover to DG set incase of power breakdown and for installation of separate energy meter as well as otherpollution control measures as per the direction of SPCB.


MITIGATORY MEASURES – VASUNDHARA’S APPROACH1. Study the utilization of Char as Activated Carbon:It has been found that the reactivity of char is high. So, in some cases, a limited quantity ofchar can be recycled back to the rotary kiln with good results. Char can be used tomanufacture activated carbon and as domestic fuel.2. Study of utilization of Char Fines in Fuel Briquettes formation:The briquettes manufactured from coal char mixed with coal fines are used as a fuel in brickkilns. The rejects and wastes of bricks have been reduced considerably with the use of thesebriquettes, besides reduction of cost of fuel.3. Study of utilization of Exhaust Gas Dust for building bricks:Exhaust Gas Dust can be used for building bricks for construction purposes.4. Establishment of Waste Heat based power plants:Suggest the establishment of Waste Heat based power plants to encourage utilization ofwaste gases. Suitable amendment to the state legislation has already been proposed - Properimplementation and execution must be ensured.5. Research on DRI Plant Waste:The research organizations of the state must rise to the occasion to find methods forutilization of the DRI Plant Waste; because the growth potential of DRI plants in the countryis quite high and steel production through DRI and induction furnace route is the cheapest ofall the processes in the world today.6. Ensure control on the pollution from the DRI plant through: <strong>In</strong>stallation of suitable de-dusting/ dust extracting equipments at dust emitting points. Suitable gas cleaning equipment such as ESP or gas quenching system should beinstalled. Ensure suitable methods of storing of raw material waste (raw material fines) anddisposal of the same. Suitable disposal of the sludge of waste water and reuse of wastewater. The mosteffective way is to save all waste water for reuse without allowing them to mix with anyother waste stream. Utilization of waste char for water purification, making domestic fuel briquettes, and asactivated carbon. The stockyard should be judiciously planned to avoid flying of dust inair.CONCLUSIONIt is a fact that the gainful utilization of the generated wastes plays a vital role in the profitability ofany organization. From the foregoing discussions, it is clear that the utilization of DRI plant wastesneed to be strengthened in order to abate future threat to the environment, besides generating profitsfor the organization.
