    The incorporation of petroleum coke as an additive in industrial coking coal blends is a practice often used by steel companies. A suitable blast furnace coke produced by replacing part of the coking coal blend with a suitable petroleum coke (addition of 5 to 15%), was made by Great Lakes Carbon Corporation and successfully tested at several blast furnaces. This coke had lower reactivity, less ash and slightly higher sulfur content than coke made without the addition of petroleum coke. In contrast with these results, it has been reported in a BCRA study that additions of petroleum coke to a strong coking coal, above 5 wt%, increased coke reactivity. These differences may be explained on the basis of the coal or blend characteristics to which petroleum coke is added. Petroleum coke addition seems to give better results if the coal/blend has high fluidity. The present situation in Spain is favorable for the use of petroleum coke. So, a study of laboratory and semi-industrial scale was made to assess the possibility of using petroleum coke as an additive to the typical industrial coal blend coked by the Spanish Steel Company, ENSIDESA. The influence of the petroleum coke particle size was also studied to semi-industrial scale.

  2. Western Canadian coking coals -- Thermal rheology and coking quality

    1997-12-31

    Methods of predicting coke strength developed from the thermal rheological properties of Carboniferous coals frequently indicate that Cretaceous coals would not make high quality coke -- yet both types of coals produce coke suitable for the iron blast furnace. This paper will discuss the reasons why Western Canadian coals exhibit lower rheological values and how to predict the strength of coke produced from them.

    1986-01-01

    An improved coking process for normally solid carbonaceous materials wherein the yield of liquid product from the coker is increased by adding ammonia or an ammonia precursor to the coker. The invention is particularly useful in a process wherein coal liquefaction bottoms are coked to produce both a liquid and a gaseous product. Broadly, ammonia or an ammonia precursor is added to the coker ranging from about 1 to about 60 weight percent based on normally solid carbonaceous material and is preferably added in an amount from about 2 to about 15 weight percent.

    Johanning, J.; Reinke, M.

    1996-12-31

    To keep coke utilization in ironmaking as competitive as possible, the potential to improve the economics of coke production has to be utilized. As one measure to meet this need of its customers, Krupp Koppers has expanded its existing ECOTROL computer system for battery heating control to a comprehensive Coke Plant Management System. Increased capacity utilization, lower energy consumption, stabilization of plant operation and ease of operation are the main targets.

  16. Clean Production of Coke from Carbonaceous Fines

    SciTech Connect (OSTI)

    Craig N. Eatough

    2004-11-16

    In order to produce steel (a necessary commodity in developed nations) using conventional technologies, you must have metallurgical coke. Current coke-making technology pyrolyzes high-quality coking coals in a slot oven, but prime coking coals are becoming more expensive and slot ovens are being shut-down because of age and environmental problems. The United States typically imports about 4 million tons of coke per year, but because of a world-wide coke scarcity, metallurgical coke costs have risen from about $77 per tonne to more than $225. This coke shortage is a long-term challenge driving up the price of steel and is forcing steel makers to search for alternatives. Combustion Resources (CR) has developed a technology to produce metallurgical coke from alternative feedstocks in an environmentally clean manner. The purpose of the current project was to refine material and process requirements in order to achieve improved economic benefits and to expand upon prior work on the proposed technology through successful prototype testing of coke products. The ultimate objective of this project is commercialization of the proposed technology. During this project period, CR developed coke from over thirty different formulations that meet the strength and reactivity requirements for use as metallurgical coke. The technology has been termed CR Clean Coke because it utilizes waste materials as feedstocks and is produced in a continuous process where pollutant emissions can be significantly reduced compared to current practice. The proposed feed material and operating costs for a CR Clean Coke plant are significantly less than conventional coke plants. Even the capital costs for the proposed coke plant are about half that of current plants. The remaining barrier for CR Clean Coke to overcome prior to commercialization is full-scale testing in a blast furnace. These tests will require a significant quantity of product (tens of thousands of tons) necessitating the construction of a demonstration facility. Talks are currently underway with potential partners and investors to build a demonstration facility that will generate enough coke for meaningful blast furnace evaluation tests. If the testing is successful, CR Clean Coke could potentially eliminate the need for the United States to import any coke, effectively decreasing US Steel industry dependence on foreign nations and reducing the price of domestic steel.

  17. Inhibition of coke formation in pyrolysis furnaces

    1995-12-31

    Coke formation in pyrolysis furnaces, which thermally convert hydrocarbons to ethylene as well as other useful products, adversely affects product yields, causes furnace down time for coke removal, and shortens furnace coil life. A phosphorus-based chemical treatment program was developed to inhibit the coke formation. The anticoking performance of the phosphorus-based treatment program was studied using a bench scale coking rate measurement apparatus. The programs`s influence on coke morphology and reactor surface was addressed using SEM/EDX surface characterization techniques. For comparison, similar studies were carried out with sulfur-containing species which are conventionally used in industrial practice as furnace additives. The present work demonstrated that the phosphorus-based treatment program provided an efficient and durable surface passivation against coke formation.

  18. Mathematical modeling of clearance between wall of coke oven and coke cake

    A mathematical model was developed for estimating the clearance between the wall of the coke oven and the coke cake. The prediction model is based on the balance between the contractile force and the coking pressure. A clearance forms when the contractile force exceeds the coking pressure in this model. The contractile force is calculated in consideration of the visco-elastic behavior of the thermal shrinkage of the coke. The coking pressure is calculated considering the generation and dispersion of gas in the melting layer. The relaxation time off coke used in this model was obtained with a dilatometer under the load application. The clearance was measured by the laser sensor, and the internal gas pressure was measured in a test oven. The clearance calculated during the coking process were in good agreement with the experimental results, which supported the validity of the mathematical model.

    The deformation of the coke cake and load on the side wall during pushing were studied using an electric furnace equipped with a movable wall. Coke cake was found to deform in three stages under compressive forces. The coke cake was shortened in the pushing direction in the cake deformation stage, and load was generated on the side walls in the high wall load stage. Secondary cracks in the coke cake were found to prevent load transmission on the wall. The maximum load transmission rate was controlled by adjusting the maximum fluidity and mean reflectance of the blended coal.

    Indianapolis Coke is a merchant coke producer, supplying both foundry and blast furnace coke to the industry. The facility has three coke batteries: two 3 meter batteries, one Wilputte four divided and one Koppers Becker. Both batteries are underjet batteries and are producing 100% foundry coke at a net coking time of 30.6 hours. This paper deals with the No. 1 coke battery, which is a 72 oven, gun fired, 5 meter Still battery. No. 1 battery produces both foundry and blast furnace coke at a net coking rate of 25.4 hours. No. 1 battery was commissioned in 1979. The battery is equipped with a double collector main. Although many renovations have been completed to the battery, oven machinery and heating system, to date no major construction projects have taken place. Deterioration of the collector main was caused in part from elevated levels of chlorides in the flushing liquor, and temperature fluctuations within the collector main. The repair procedures are discussed.

  1. Factors affecting coking pressures in tall coke ovens

    The detrimental effects of excessive coking pressures, resulting in the permanent deformation of coke oven walls, have been recognized for many years. Considerable research has been undertaken worldwide in attempts to define the limits within which a plant may safely operate and to quantify the factors which influence these pressures. Few full scale techniques are available for assessing the potential of a coal blend for causing wall damage. Inference of dangerous swelling pressures may be made however by the measurement of the peak gas pressure which is generated as the plastic layers meet and coalesce at the center of the oven. This pressure is referred to in this report as the carbonizing pressure. At the Dawes Lane cokemaking plant of British Steel`s Scunthorpe Works, a large database has been compiled over several years from the regulator measurement of this pressure. This data has been statistically analyzed to provide a mathematical model for predicting the carbonizing pressure from the properties of the component coals, the results of this analysis are presented in this report.

    U.S. Steel has three major facilities remaining in Pennsylvania`s Mon Valley near Pittsburgh. The Clairton Coke Works operates 12 batteries which produce 4.7 million tons of coke annually. The Edgar Thomson Works in Braddock is a 2.7 million ton per year steel plant. Irvin Works in Dravosburg has a hot strip mill and a range of finishing facilities. The coke works produces 120 mmscfd of coke oven gas in excess of the battery heating requirements. This surplus gas is used primarily in steel re-heating furnaces and for boiler fuel to produce steam for plant use. In conjunction with blast furnace gas, it is also used for power generation of up to 90 MW. However, matching the consumption with the production of gas has proved to be difficult. Consequently, surplus gas has been flared at rates of up to 50 mmscfd, totaling 400 mmscf in several months. By 1993, several changes in key conditions provided the impetus to install equipment to inject coke oven gas into the blast furnaces. This paper describes the planning and implementation of a project to replace natural gas in the furnaces with coke oven gas. It involved replacement of 7 miles of pipeline between the coking plants and the blast furnaces, equipment capable of compressing coke oven gas from 10 to 50 psig, and installation of electrical and control systems to deliver gas as demanded.

    Visbreaking is a mild cracking process primarily used to reduce residual oil viscosity and thus decrease the amount of cutter stock required for blending to heavy fuels specification. It can also be used to produce incremental quantities of gasoline, middle distillates and catalytic cracker feeds. This process was widely used in the 1930s and 1940s and became obsolete until a few years ago. When the need for increased conversion of residues to light products became desirable, visbreaking offered economic advantages to many refining schemes - especially in Western Europe. Between 1978-1981, Exxon brought on stream seven visbreakers ranging from 1900 to 9100 tons/SD capacity. In January 1983, the world-wide visbreaking capacity was over 2 MM B/SD. The visbreaking process and its application in refinery operations have been well described. In general, the process economics improve as the process severity is increased but it is limited by coke formation in the process. For this reason, they have studied the kinetics of coke formation in the visbreaking process.

    This paper reports the results of the studies carried out on the optimization of particle size distribution, the rheological characteristics and stability of highly loaded petroleum coke-water slurry using three additives. The solids loading achieved in the slurries were in the range of 65% to 75.6% depending on the additives used. Slurry viscosity varied between 267 to 424 mPas at 128 s{sup {minus}} shear rate. The petroleum coke-water slurries exhibited pseudoplastic characteristics with yield tending towards Bingham plastic as the solids loading progressively increased. The effect of addition of petroleum coke to the extent of 25% in coal-water slurry prepared from low ash Ledo coal of Makum field in Assam was also examined. The slurry containing coal-petroleum coke blend showed better stability, having shelf life of 7 days as compared to 5 days in the case of petroleum coke-water slurry.

    Apart from coke which is the actual valuable material a coke oven plant also produces a substantial volume of waste water. These effluent water streams are burdened with organic components (e.g. phenols) and inorganic salts (e.g. NH{sub 4}Cl); due to the concentration of the constituents contained therein these effluent waters must be subjected to a specific treatment before they can be introduced into public waters. For some years a lot of separation tasks have been solved successfully by applying the membrane technology. It was especially the growing number of membrane facilities for cleaning of landfill leakage water whose composition can in fact be compared with that of coking plant waste waters (organic constituents, high salt fright, ammonium compounds) which gave Thyssen Still Otto Anlagentechnik the idea for developing a process for coke plant effluent treatment which contains the membrane technology as an essential component.

    The authors discuss how recent supply shortages of super-premium quality needle cokes, plus the expectation of increased shortfalls in the future, indicate that refiners should consider upgrading their operations to fill these demands. Calcined, super-premium needle cokes are currently selling for as much as $550/metric ton, fob producer, and increasing demand will continue the upward push of the past year. Needle coke, in its calcined form, is the major raw material in the manufacture of graphite electrodes. Used in steelmaking, graphite electrodes are the electrical conductors that supply the heat source, through arcing electrode column tips, to electric arc steel furnaces. Needle coke is commercially available in three grades - super premium, premium, and intermediate. Super premium is used to produce electrodes for the most severe electric arc furnace steelmaking applications, premium for electrodes destined to less severe operations, and intermediate for even less critical needs.

    Delayed coking evolved steadily over the early to mid 1900s to enable refiners to convert high boiling, residual petroleum fractions to light products such as gasoline. Pound for pound, coking is the most energy intensive of any operation in a modern refinery. Large amounts of energy are required to heat the thick, poor-quality petroleum residuum to the 900 to 950 degrees F required to crack the heavy hydrocarbon molecules into lighter, more valuable products. One common misconception of delayed coking is that the product coke is a disadvantage. Although coke is a low valued (near zero economic value) byproduct, compared to transportation fuels, there is a significant worldwide trade and demand for coke as it is an economical fuel. Coke production has increased steadily over the last ten years, with further increases forecast for the foreseeable future. Current domestic production is near 111,000 tons per day. A major driving force behind this increase is the steady decline in crude quality available to refiners. Crude slates are expected to grow heavier with higher sulfur contents while environmental restrictions are expected to significantly reduce the demand for high-sulfur residual fuel oil. Light sweet crudes will continue to be available and in even greater demand than they are today. Refiners will be faced with the choice of purchasing light sweet crudes at a premium price, or adding bottom of the barrel upgrading capability, through additional new investments, to reduce the production of high-sulfur residual fuel oil and increase the production of low-sulfur distillate fuels. A second disadvantage is that liquid products from cokers frequently are unstable, i.e., they rapidly form gum and sediments. Because of intermediate investment and operating costs, delayed coking has increased in popularity among refiners worldwide. Based on the 2000 Worldwide Refining Survey published in the Oil and Gas, the delayed coking capacity for 101 refineries around the world is 2,937,439 barrels/calendar day. These cokers produce 154,607 tons of coke per day and delayed coking accounts for 88% of the world capacity. The delayed coking charge capacity in the United States is 1,787,860 b/cd. Despite its wide commercial use, only relatively few contractors and refiners are truly knowledgeable in delayed-coking design, so that this process carries with it a ''black art'' connotation. Until recently, the expected yield from cokers was determined by a simple laboratory test on the feedstock. As a result of Tulsa University's prior related research, a process model was developed that with additional work could be used to optimize existing delayed cokers over a wide range of potential feedstocks and operating conditions. The objectives of this research program are to: utilize the current micro, batch and pilot unit facilities at The University of Tulsa to enhance the understanding of the coking process; conduct additional micro and pilot unit tests with new and in-house resids and recycles to make current optimization models more robust; conduct focused kinetic experiments to enhance the furnace tube model and to enhance liquid production while minimizing sulfur in the products; conduct detailed foaming studies to optimize the process and minimize process upsets; quantify the parameters that affect coke morphology; and to utilize the knowledge gained from the experimental and modeling studies to enhance the computer programs developed in the previous JIP for optimization of the coking process. These refined computer models will then be tested against refinery data provided by the member companies. Novel concepts will also be explored for hydrogen sulfide removal of furnace gases as well as gas injection studies to reduce over-cracking.

    Due to the bad condition of batteries and many ovens under repair, Hoogovens was forced to partially repair and rebuild the Coke plant No. 1. The production of coke at Coke plant No. 1 is realized in 3 production blocks subdivided in 6 batteries. Besides a renovated installation, all coke oven machines were renewed. A total of five identical machine sets are available. Each consists of a pusher machine, larry car, coke guide and quench car with diesel locomotive. A complete automated control system was implemented. The main objectives were a highly regular coking and pushing process, automated traveling and positioning and a centrally coordinated interlocking of machine functions. On each operational machine however an operator performed the supervisory control of the automated machine functions. After years of good experience with the automated system, economical reasons urged further personnel reduction from 1994 on. Totally 375 people were involved, including the maintenance department. To reduce the occupation at coke plant No. 1, the coke guide was the first machine to be fully automated because of the isolated and uncomfortable working place.

    Rautaruukki is a modern integrated Finnish steel works having a production of 2.4 mil. t/year of flat products. The total fuel consumption of the two blast furnaces in 1994 was 435 kg/t HM. Coke used was 345 kg/t HM and oil injection was 90 kg/t HM. The coking plant was taken in to operation in 1987 and is the only one in Finland, which means that the coking tradition is very short. Coke production is 0.9 mil. t/year. The coking blends include 70--80% medium volatile coals having a wide range of total dilatation. From time to time disturbances in the operation of the blast furnaces have occurred in spite of the fact that the reactivity of the coke used has remained constant or even decreased. It was thought necessary to investigate the factors affecting coke reactivity, in order to better understand the results of the reactivity test. This paper deals with carbonization tests done in a 7 kg test oven using nine individual coals having volatile-matter contents of 17--36% (dry) and seven blends made from these coals. Coke reactivity with CO{sub 2} at 1100 C (CRI) and coke strength after reaction (CSR) were determined using the test developed by the Nippon Steel Corporation. The influence of coke carbon form, porosity and especially ash mineralogy on the coke reactivity were examined. The effects of some additives; petroleum coke (pet coke), the spillage material from the coke ovens and oxidized coal, on coke quality were also studied. Typical inorganic minerals found in coals were added to one of the high volatile coals, which was then coked to determine the affect of the minerals on the properties of the coke produced.

    The dispersed particle solution model of petroleum residua structure was used to develop predictors for pyrolytic coke formation. Coking Indexes were developed in prior years that measure how near a pyrolysis system is to coke formation during the coke formation induction period. These have been demonstrated to be universally applicable for residua regardless of the source of the material. Coking onset is coincidental with the destruction of the ordered structure and the formation of a multiphase system. The amount of coke initially formed appears to be a function of the free solvent volume of the original residua. In the current work, three-dimensional coke make predictability maps were developed at 400 C, 450 C, and 500 C (752 F, 842 F, and 932 F). These relate residence time and free solvent volume to the amount of coke formed at a particular pyrolysis temperature. Activation energies for two apparent types of zero-order coke formation reactions were estimated. The results provide a new tool for ranking residua, gauging proximity to coke formation, and predicting initial coke make tendencies.

  1. REDUCING POWER PRODUCTION COSTS BY UTILIZING PETROLEUM COKE

    1999-09-01

    Petroleum coke, a byproduct of the petroleum-refining process, is an attractive primary or supplemental fuel for power production primarily because of a progressive and predictable increase in the production volumes of petroleum coke (1, 2). Petroleum coke is most commonly blended with coal in proportions suitable to meet sulfur emission compliance. Petroleum coke is generally less reactive than coal; therefore, the cofiring of petroleum coke with coal typically improves ignition, flame stability, and carbon loss relative to the combustion of petroleum coke alone. Although petroleum coke is a desirable fuel for producing relatively inexpensive electrical power, concerns about the effects of petroleum coke blending on combustion and pollution control processes exist in the coal-fired utility industry (3). The Energy & Environmental Research Center (EERC) completed a 2-year technical assessment of petroleum coke as a supplemental fuel. A survey questionnaire was sent to seven electric utility companies that are currently cofiring coal and petroleum coke in an effort to solicit specific suggestions on research needs and fuel selections. An example of the letter and survey questionnaire is presented in Appendix A. Interest was expressed by most utilities in evaluating the effects of petroleum coke blending on grindability, combustion reactivity, fouling, slagging, and fly ash emissions control. Unexpectedly, concern over corrosion was not expressed by the utilities contacted. Although all seven utilities responded to the question, only two utilities, Northern States Power Company (NSP) and Ameren, sent fuels to the EERC for evaluation. Both utilities sent subbituminous coals from the Power River Basin and petroleum shot coke samples. Petroleum shot coke is produced unintentionally during operational upsets in the petroleum refining process. This report evaluates the effects of petroleum shot coke blending on grindability, fuel reactivity, fouling/slagging, and electrostatic precipitator (ESP) fly ash collection efficiency.

    This paper describes a model-based strategy for coke battery control at BHP Steel`s operations in Pt Kembla, Australia. The strategy uses several models describing the battery thermal and coking behavior. A prototype controller has been installed on the Pt Kembla No. 6 Battery (PK6CO). In trials, the new controller has been well accepted by operators and has resulted in a clear improvement in battery thermal stability, with a halving of the standard deviation of average battery temperature. Along with other improvements to that battery`s operations, this implementation has contributed to a 10% decrease in specific battery energy consumption. A number of enhancements to the low level control systems on that battery are currently being undertaken in order to realize further benefits.

  3. REDUCING POWER PRODUCTION COSTS BY UTILIZING PETROLEUM COKE

    1998-09-01

    A Powder River Basin subbituminous coal from the North Antelope mine and a petroleum shot coke were received from Northern States Power Company (NSP) for testing the effects of parent fuel properties on coal-coke blend grindability and evaluating the utility of petroleum coke blending as a strategy for improving electrostatic precipitator (ESP) particulate collection efficiency. Petroleum cokes are generally harder than coals, as indicated by Hardgrove grindability tests. Therefore, the weaker coal component may concentrate in the finer size fractions during the pulverizing of coal-coke blends. The possibility of a coal-coke size fractionation effect is being investigated because it may adversely affect combustion performance. Although the blending of petroleum coke with coal may adversely affect combustion performance, it may enhance ESP particulate collection efficiency. Petroleum cokes contain much higher concentrations of V relative to coals. Consequently, coke blending can significantly increase the V content of fly ash resulting from coal-coke combustion. Pentavalent vanadium oxide (V{sub 2}O{sub 5}) is a known catalyst for transforming gaseous sulfur dioxide (SO{sub 2}[g]) to gaseous sulfur trioxide (SO{sub 3}[g]). The presence of SO{sub 3}(g) strongly affects fly ash resistivity and, thus, ESP performance.

    The paper discusses the formation of cyanides in coke oven gas and describes and compares waste processing options. These include desulfurization by aqueous ammonia solution, desulfurization using potash solution, desulfurization in oxide boxes, decomposition of NH{sub 3} and HCN for gas scrubbing. Waste water treatment methods include chemical oxidation, precipitation, ion exchange, reverse osmosis, and biological treatment. It is concluded that biological treatment is the most economical process, safe in operation and requires a minimum of manpower.

    Hydrogenation residue is the product left over when petroleum residue feedstocks (or coal) are treated by, e.g. the Veba Combi Cracking (VCC) process. Many tests in semitechnical and full-sized coke ovens were carried out with hydrogenation residue (HR) as an additive in coking coal blends for the production of blast furnace coke or foundry coke. The results of the investigations reported in this paper demonstrate that HR is a very promising alternative for enlarging the coking coal basis compared to other processes or the use of other additives. The application of HR on an industrial scale did not indicate any negative impact on the handling of the hydrogenation residue or on the operation of the coke oven battery.

    Upgrading heavy oils is becoming increasingly important as the world crude slate gets heavier and demand for light products increases. But most upgrading processes must contend with problems related to coke formation during hydrotreating. Three researchers have found that materials having high radical-scavenging ability can reduce coke formation when applied to hydrotreating heavy oils. And these materials can be produced from heavy petroleum fractions. The paper discusses coke formation, the research program, and the pilot plant.

    Citizens Gas and Coke Utility is a Public Charitable Trust which operates as the Department of Utilities of the City of Indianapolis, Indiana. Indianapolis Coke, the trade name for the Manufacturing Division of the Utility, operates a by-products coke plant in Indianapolis, Indiana. The facility produces both foundry and blast furnace coke. Surplus Coke Oven gas, generated by the process, is mixed with Natural Gas for sale to industrial and residential customers. In anticipation of regulatory developments, beginning in 1990, Indianapolis Coke undertook the task to develop an alternate Coke Oven Gas desulfurization technology for its facility. The new system was intended to perform primary desulfurization of the gas, dramatically extending the oxide bed life, thus reducing disposal liabilities. Citizens Gas chose the VACASULF technology for its primary desulfurization system. VACASULF requires a single purchased material, Potassium Hydroxide (KOH). The KOH reacts with Carbon Dioxide in the coke Oven Gas to form Potassium Carbonate (potash) which in turn absorbs the Hydrogen Sulfide. The rich solution releases the absorbed sulfide under strong vacuum in the desorber column. Operating costs are reduced through utilization of an inherent heat source which is transferred indirectly via attendant reboilers. The Hydrogen Sulfide is transported by the vacuum pumps to the Claus Kiln and Reactor for combustion, reaction, and elemental Sulfur recovery. Regenerated potash solution is returned to the Scrubber.

    1995-12-01

    A chamber pressure regulation (PROven), especially effective in regard to emission control problems of coke ovens is introduced for the first time. Because of the partial vacuum in the collecting main system, it is possible to keep the oven`s raw gas pressure constant on a low level over the full coking time. The individual pressure control for each chamber is assured directly as a function of the oven pressure by an immersion system controlling the flow resistance of the collecting main valve. The latter is a fixed-position design (system name ``FixCup``). By doing away with the interdependence of collecting main pressure and chamber pressure, a parameter seen as a coking constant could not be made variable. This opens a new way to reduce coke oven emissions and simultaneously to prevent the ovens from damage caused by air ingress into the oven.

The industrial application of petroleum coke residual oil slurry requires full knowledge of its flow behavior. This paper will present the results of an experimental investigation undertaken to study the Theological properties using a rotating viscometer at shear rate up to 996 s{sup -1}. The effects of temperature, concentration, particle size distribution and additives are also investigated. The experiments show that petroleum coke residual oil slurry exhibits pseudoplastic behavior, which has favorable viscosity property under a certain condition and has broad prospect to be applied on oil-fired boilers.

    Coke is a by-product in petroleum fluid catalytic cracking (FCC) processes. The concentration of coke in an FCC riser reactor is a critical parameter used to evaluate the riser performance. A coke formation and transport model was developed. It was incorporated into a computational fluid dynamic (CFD) computer code, ICRKFLO, to simulate the coke formation processes in an FCC riser reactor. Based on a similar process, a soot formation model can be derived from the coke formation model and used for diesel combustion processes, where soot is emitted as one of the primary pollutants.

    Members of the American Coke and Coal Chemicals Institute (ACCCI), as responsible corporate citizens, have embraced the concepts of crisis management and progress down the various paths of planning and preparation, monitoring, media communications, community outreach, emergency response, and recovery. Many of the concepts outlined here reflect elements of crisis management guidelines developed by the Chemical Manufacturers Association (CMA). At a coke plant, crises can take the form of fires, chemical releases, labor strikes, feedstock supply disruptions, and excessive snowfall, just to name a few. The CMA defines a crisis as: ``an unplanned event that has the potential to significantly impact a company`s operability or credibility, or to pose a significant environment, economic or legal liability``; and crisis management as: ``those activities undertaken to anticipate or prevent, prepare for, respond to and recover from any incident that has the potential to greatly affect the way a company conducts its business.

However, working as quickly as possible to dig out of the burden and rehabilitate various facilities, the company managed to restart the No. 3 BF on April 2. After the restart, which went smoothly, production was shifted into the low coke rate operation which was being promoted before the disaster. In October, 1995, only seven months after the restart, the nation record of 296 kg/t low coke rate could be achieved. Subsequently, in January, 1996, coke rate reached 290 kg/t and the low coke rate operation was renewed. Since that time the same level of coke rate has been maintained.

This CDQ which went on stream in March 1993 cools the whole coke production output from the Kaiserstuhl coke plant in counterflow to an inert cooling gas. This brief overview on the whole CDQ plant should elucidate the complex of problems posed when trying to make an exact plant revision plan. After all it was impossible to evaluate or to assess all the interior process technology relevant components during the planning stage as the plant was in operation. The revision data for the first interior check was determined and fixed by the statutory rule for steam boilers and pressure vessels. The relevant terms for this check are mandatorily prescribed. In liaison with the testing agency (RW TUEV) the date for the first revision was fixed for April 1995, that means two years after the first commissioning.

    The need to upgrade the ammonia removal process at the Acme Steel Coke Plant developed with the installation of the benzene NESHAP (National Emission Standard for Hazardous Air Pollutants) equipment, specifically the replacement of the final cooler. At Acme Steel it was decided to replace the existing open cooling tower type final cooler with a closed loop direct spray tar/water final cooler. This new cooler has greatly reduced the emissions of benzene, ammonia, hydrogen sulfide and hydrogen cyanide to the atmosphere, bringing them into environmental compliance. At the time of its installation it was not fully recognized as to the effect this would have on the coke oven gas composition. In the late seventies the decision had been made at Acme Steel to stop the production of ammonia sulfate salt crystals. The direction chosen was to make a liquid ammonia sulfate solution. This product was used as a pickle liquor at first and then as a liquid fertilizer as more markets were developed. In the fall of 1986 the ammonia still was brought on line. The vapors generated from the operation of the stripping still are directed to the inlet of the ammonia absorber. At that point in time it was decided that an improvement to the cyclical ammonia removal process was needed. The improvements made were minimal yet allowed the circulation of solution through the ammonia absorber on a continuous basis. The paper describes the original batch process and the modifications made which allowed continuous removal.

    The coke plant is a working environment involving heavy dust emissions, high heat and demanding physical labor. The labor-saving operation of the coke plant is an essential issue from the standpoints of not only improvement in working environment, but also reduction in fixed cost by enhancement of labor productivity. Under these circumstances, Nippon Steel has implemented the automation of coke oven machines. The first automatic operation system for coke oven machinery entered service at Oita Works in 1992, followed by the second system at the No. 5 coke oven battery of the coke plant at Yawata Works. The Yawata automatic operation system is characterized by the installation of coke oven machinery to push as many as 140 ovens per day within a short cycle time, such as a preliminary ascension pipe cap opening car and cycle time simulator by the manned operation of the pusher, which is advantageous from the standpoint of investment efficiency, and by the monitoring of other oven machines by the pusher. These measures helped to reduce the manpower requirement to 2 persons per shift from 4 persons per shift. The system entered commercial operation in March, 1994 and has been smoothly working with an average total automatic rate of 97%. Results from the startup to recent operation of the system are reported below.

    Coke is needed in the blast furnace as the main fuel and chemical reactant and the main product of a coke plant. The second main product of the coke plant is coke oven gas. During treatment of the coke oven gas some coal chemicals like tar, ammonia, sulphur and benzole can be recovered as by-products. Since the market prices for these by-products are rather low and often erratic it does not in most cases justify the investment to recover these products. This is the reason why modern gas treatment plants only remove those impurities from the crude gas which must be removed for technical and environmental reasons. The cleaned gas, however, is a very valuable product as it replaces natural gas in steel work furnaces and can be used by other consumers. The surplus can be combusted in the boiler of a power plant. A good example for an optimal plant layout is the new coke oven facility of Thai Special Steel Industry (TSSI) in Rayong. The paper describes the TSSI`s coke oven gas treatment plant.

    The overall aim of the project is to demonstrate the performance and practical use of a laser ultrasonic probe for measuring the thickness of coke deposits located within the high temperature tubes of a thermal cracking furnace. This aim will be met by constructing an optical probe that will be tested using simulated coke deposits that are positioned inside of a bench-scale furnace. Successful development of the optical coke detector will provide industry with the only available method for on-line measurement of coke deposits. The optical coke detector will have numerous uses in the refining and petrochemical sectors including monitoring of visbreakers, hydrotreaters, delayed coking units, vacuum tower heaters, and various other heavy oil heating applications where coke formation is a problem. The coke detector will particularly benefit the olefins industry where high temperature thermal crackers are used to produce ethylene, propylene, butylene and other important olefin intermediates. The ethylene industry requires development of an on-line method for gauging the thickness of coke deposits in cracking furnaces because the current lack of detailed knowledge of coke deposition profiles introduces the single greatest uncertainty in the simulation and control of modern cracking furnaces. The laser ultrasonic coke detector will provide operators with valuable new information allowing them to better optimize the decoking turnaround schedule and therefore maximize production capacity.

    The new technology for protecting the coking chamber bricks from damage by hard-pushing is described. The technology consists of the glass coating on the wall bricks and a wall cleaner to blow deposited carbon. For the glass coating, a specially developed glaze is sprayed onto the wall bricks by a spraying device developed to completely spray one coking chamber in a few minutes. The wall cleaner is installed on a pusher ram in the facility to automatically blow air at a sonic speed during coke pushing. The life of the glazed layer is estimated to be over two years.

    This paper reports that significant reduction in the rate of coke formation during naphtha pyrolysis was achieved by adding benzyl diethyl phosphite or triphenylphosphine sulfide to the feed. Although the yield of carbon oxides was reduced, there was no effect of these additives on the hydrocarbon yields. Addition of these organophosphorus compounds significantly reduced the concentration of metals, such as iron, nickel, and chromium, incorporated in the coke. A previously proposed model for coke inhibition due to the formation of a passivating metal-phosphorus complex could satisfactorily correlate the data.

    OSHA's Process Safety Management (PSM) standard went into effect on May 26, 1992. Explosions at various industrial facilities that claimed the lives of workers over the past several years were the catalyst for the new federal regulations. The new PSM standard deals with 130 specific chemicals along with flammable liquids and gases used at nearly 25,000 worksites. The performance-based PSM standard consists of 14 elements that establish goals and describe basic program elements to fulfill these goals. The PSM standard requires employers to conduct a process hazard analysis to examine potential problems and determine what preventative measures should be taken. Key elements include employee training, written operating procedures, safety reviews and maintenance requirements to insure the mechanical integrity of critical components. The presentation will cover the evolution of OSHA's PSM standard, the requirements of the 14 elements in the PSM standard and discuss the significant achievements in the development and implementation of the PSM process at US Steel's Clairton coke plant.

    1995-12-01

    Injection rates at Taranto blast furnaces Nos. 2 and 4, for more than 16 months, was maintained above 175 kg/thm. Monthly average injection rate for two months stabilized above 190 kg/thm. This performance was possible due to the very high combined availabilities of Taranto blast furnaces and the KST injection system. Based upon this experience the quantitative relationships between coke/coal and blast furnace operational parameters were studied and are shown graphically. During this period due to coke quality changes, injection rate had to be reduced. The effect of using coke breeze in coke/ferrous charge as well as coal blend was also evaluated. Permeability of the furnace was found to be directly affected by O{sub 2} enrichment level, while at a high PCI rate no correlation between actual change in coke quality and permeability could be established. The future of PCI technology lies in better understanding of relationships between material specifications and blast furnace parameters of which permeability is of prime importance.

    An automatic heating control system for coke oven batteries was developed in 1985 for the Burns Harbor No. 1 battery and reported in the 1989 Ironmaking Conference Proceedings. The original system was designed to maintain a target coke temperature at a given production level under normal operating conditions. Since 1989, enhancements have been made to this control system so that it can also control the battery heating when the battery is under repair. The new control system has improved heating control capability because it adjusts the heat input to the battery in response to anticipated changes in the production schedule. During a recent repair of this 82 oven battery, the pushing schedule changed from 102 ovens/day to 88 ovens/day, then back to 102 ovens/day, then to 107 ovens/day. During this repair, the control system was able to maintain the coke temperature average standard deviation at 44 F, with a maximum 75 F.

    Facility-specific information on pollution was obtained for 36 coke plants and 46 oil refineries in the US and matched with information on populations surrounding these 82 facilities. These data were analyzed to determine whether environmental inequities were present, whether they were more economic or racial in nature, and whether the racial composition of nearby communities has changed significantly since plants began operations. The Census tracts near coke plants have a disproportionate share of poor and nonwhite residents. Multivariate analyses suggest that existing inequities are primarily economic in nature. The findings for oil refineries are not strongly supportive of the environmental inequity hypothesis. Rank ordering of facilities by race, poverty, and pollution produces limited (although not consistent) evidence that the more risky facilities tend to be operating in communities with above-median proportions of nonwhite residents (near coke plants) and Hispanic residents (near oil refineries). Over time, the radical makeup of many communities near facilities has changed significantly, particularly in the case of coke plants sited in the early 1900s. Further risk-oriented studies of multiple manufacturing facilities in various industrial sectors of the economy are recommended.

    A bio-oil production process involving torrefaction pretreatment, catalytic esterification, pyrolysis, and secondary catalytic processing significantly reduces yields of reactor char, catalyst coke, and catalyst tar relative to the best-case conditions using non-torrefied feedstock. The reduction in coke as a result of torrefaction was 28.5% relative to the respective control for slow pyrolysis bio-oil upgrading. In fast pyrolysis bio-oil processing, the greatest reduction in coke was 34.9%. Torrefaction at 275.degree. C. reduced levels of acid products including acetic acid and formic acid in the bio-oil, which reduced catalyst coking and increased catalyst effectiveness and aromatic hydrocarbon yields in the upgraded oils. The process of bio-oil generation further comprises a catalytic esterification of acids and aldehydes to generate such as ethyl levulinate from lignified biomass feedstock.

    The coke plants at the Kwangyang works has adopted an Automatic Battery Control (ABC) system which consists of four main parts, battery heating control, underfiring heat and waste gas oxygen control, pushing and charging schedule and Autotherm-S that measures heating wall temperature during pushing. The measured heating wall temperature is used for calculating Mean Battery Temperature (MBT) which is average temperature of flues for a battery, but the Autotherm-S system can not provide the flue temperatures of an oven. This work attempted to develop mathematical models for the estimation of the flue temperature using the measured heating wall temperature and to examine fitness of the mathematical model for the coke plant operation by analysis of raw gas temperature at the stand pipe. Through this work it is possible to reflect heating wall temperature in calculating MBT for battery heating control without the interruption caused by a maintenance break.

    The present study investigates the effect of addition of waste rubber tires on the combustion behavior of its blends with coke for carbon injection in electric arc furnace steelmaking. Waste rubber tires were mixed in different proportions with metallurgical coke (MC) (10:90, 20:80, 30:70) for combustion and pyrolysis at 1473 K in a drop tube furnace (DTF) and thermogravimetric analyzer (TGA), respectively. Under experimental conditions most of the rubber blends indicated higher combustion efficiencies compared to those of the constituent coke. In the early stage of combustion the weight loss rate of the blends is much faster compared to that of the raw coke due to the higher volatile yield of rubber. The presence of rubber in the blends may have had an impact upon the structure during the release and combustion of their high volatile matter (VM) and hence increased char burnout. Measurements of micropore surface area and bulk density of the chars collected after combustion support the higher combustion efficiency of the blends in comparison to coke alone. The surface morphology of the 30% rubber blend revealed pores in the residual char that might be attributed to volatile evolution during high temperature reaction in oxygen atmosphere. Physical properties and VM appear to have a major effect upon the measured combustion efficiency of rubber blends. The study demonstrates that waste rubber tires can be successfully co-injected with metallurgical coke in electric arc furnace steelmaking process to provide additional energy from combustion. 44 refs., 11 figs., 2 tabs.

    In selective hydrogenation of acetylene in excess ethylene, considerable amounts of coke or {open_quotes}green oils{close_quotes} are formed and accumulate on the catalyst. A fraction of the acetylene undergoes oligomerization reactions producing C{sub 4}`s and larger hydrocarbons. Compounds larger than C{sub 8} are retained on the catalysts surface or as a condensed phase in the pore system. The reaction mechanism is largely unknown but several authors have postulated that oligomerization occurs through dissociatively adsorbed acetylene (2), i.e., C{sub 2}H(ads) and C{sub 2}(ads). In this paper a novel method of studying the coke formation on a catalyst is introduced. Deuterium is incorporated in the coke during hydrogenation of acetylene, and during temperature-programmed oxidation (TPO) experiments the deuterium content is analyzed. The objective is to shed some light on the mechanism for oligomer formation in this system. The catalyst, Pd/{alpha}-Al{sub 2}O{sub 3}, was prepared by the impregnation of {alpha}-alumina (Sued-Chemie) with a solution of Pd(NO{sub 3}){sub 2} in 30% HNO{sub 3}. 8 refs., 4 figs.

    The basis for this study was an antitrust suit brought by the Federal Trade Commission against the Great Lakes Carbon Corp., a processor and reseller of green petroleum coke, and eight petroleum refiners. The respondents in this case were accused of using long-term contracts to foreclose the markets for both green and processed petroleum coke. Chapter 1 develops a theory of exchange and the contracts governing exchange. Chapter 2 describes the petroleum-coke industry and the nature of green coke exchange. It explains the reasons for the highly concentrated structure of the green-coke market in terms of the technology of petroleum-coke production and consumption and the physical and byproduct nature of petroleum coke. Chapter 3 takes a large number of green-coke contracts and breaks them down into their various relevant provisions. These provisions are then grouped according to their purpose and the characteristics of the firms employing them and shows that differences between the contracts can be explained by differences in the risks to firms of engaging in green coke exchange. Chapter 4 discusses the implications of vertical restrictions from the point of view of relational contracting using the data adduced in Chapter 3.

    This paper proposes a novel multifunctional energy system (MES), which cogenerates coke, hydrogen, and power, through the use of coal and coke oven gas (COG). In this system, a new type of coke oven, firing coal instead of COG as heating resource for coking, is adopted. The COG rich in H{sub 2} is sent to a pressure swing adsorption (PSA) unit to separate about 80% of hydrogen first, and then the PSA purge gas is fed to a combined cycle as fuel. The new system combines the chemical processes and power generation system, along with the integration of chemical conversion and thermal energy utilization. In this manner, both the chemical energy of fuel and thermal energy can be used more effectively. With the same inputs of fuel and the same output of coking heat, the new system can produce about 65% more hydrogen than that of individual systems. As a result, the thermal efficiency of the new system is about 70%, and the exergy efficiency is about 66%. Compared with individual systems, the primary energy saving ratio can reach as high as 12.5%. Based on the graphical exergy analyses, we disclose that the integration of synthetic utilization of COG and coal plays a significant role in decreasing the exergy destruction of the MES system. The promising results obtained may lead to a clean coal technology that will utilize COG and coal more efficiently and economically.

    The cracking of oil refinery off-gas, simulated with a gas mixture containing methane (51%), ethylene (21.4%), ethane (21.1%), and propane (6.5%), over a coal char, petroleum coke, and quartz, respectively, has been studied in a fixed bed reactor. The experiments were performed at temperatures between 850 and 1000{sup o}C and at atmospheric pressure. The results show that the conversions of all species considered increased with increasing temperature. Ethane and propane completely decomposed over all three bed materials in the temperature range investigated. However, the higher initial conversion rates of methane and ethylene cracking at all temperatures were observed only over the coal char and not on the petroleum coke and quartz, indicating a significant catalytic effect of the coal char on methane and ethylene cracking. Methane and ethylene conversions decreased with reaction time due to deactivation of the coal char by carbon deposition on the char surface and, in the later stage of a cracking experiment, became negative, suggesting that methane and ethylene had been formed during the cracking of ethane and propane. 16 refs., 13 figs., 2 tabs.

    Green petroleum coke (GPC) is an oil refining byproduct that can be used directly as a solid fuel or as a feedstock for the production of calcined petroleum coke. GPC contains a high amount of volatiles and sulfur. During the calcination process, the GPC is heated to remove the volatiles and sulfur to produce purified calcined coke, which is used in the production of graphite, electrodes, metal carburizers, and other carbon products. Currently, more than 80% of calcined coke is produced in rotary kilns or rotary hearth furnaces. These technologies provide partial heat utilization of the calcined coke to increase efficiency of the calcination process, but they also share some operating disadvantages. However, coke calcination in an electrothermal fluidized bed (EFB) opens up a number of potential benefits for the production enhancement, while reducing the capital and operating costs. The increased usage of heavy crude oil in recent years has resulted in higher sulfur content in green coke produced by oil refinery process, which requires a significant increase in the calcinations temperature and in residence time. The calorific value of the process off-gas is quite substantial and can be effectively utilized as an opportunity fuel for combined heat and power (CHP) production to complement the energy demand. Heat recovered from the product cooling can also contribute to the overall economics of the calcination process. Preliminary estimates indicated the decrease in energy consumption by 35-50% as well as a proportional decrease in greenhouse gas emissions. As such, the efficiency improvement of the coke calcinations systems is attracting close attention of the researchers and engineers throughout the world. The developed technology is intended to accomplish the following objectives: - Reduce the energy and carbon intensity of the calcined coke production process. - Increase utilization of opportunity fuels such as industrial waste off-gas from the novel petroleum coke calcination process. - Increase the opportunity of heat (chemical and physical) utilization from process off-gases and solid product. - Develop a design of advanced CHP system utilizing off-gases as an opportunity fuel for petroleum coke calcinations and sensible heat of calcined coke. A successful accomplishment of the aforementioned objectives will contribute toward the following U.S. DOE programmatic goals: - Drive a 25% reduction in U. S. industrial energy intensity by 2017 in support of EPAct 2005; - Contribute to an 18% reduction in U.S. carbon intensity by 2012 as established by the Administrations National Goal to Reduce Emissions Intensity. 8

    The hydrogen contained in blast furnace gases exerts a variety of physical, thermochemical, and kinetic effects as the gases pass through the various zones. The hydrogen is derived from two sources: (1) the dissociation of moisture in the blast air (ambient and injected with hot blast), and (2) the release from partial combustion of supplemental fuels (including moisture in atomizing water, steam, or transport air, if any). With each atom of oxygen (or carbon), the molar amounts of hydrogen released are more than six times higher for natural gas than for coal, and two times higher for natural gas than for oil. Injection of natural gas in a blast furnace is not a new process. Small amounts of natural gas--about 50--80 lb or 1,100--1,700 SCF/ton of hot metal--have been injected in many of the North American blast furnaces since the early 1960s, with excellent operating results. What is new, however, is a batter understanding of how natural gas reacts in the blast furnace and how natural gas and appropriate quantities of oxygen can be used to increase the driving rate or combustion rate of carbon (coke) in the blast furnace without causing hanging furnace and operating problems. The paper discusses the factors limiting blast furnace productivity and how H{sub 2} and O{sub 2} can increase productivity.

    Ashless coal, also known as HyperCoal (HPC), was produced by thermal extraction of three coals of different ranks (Gregory caking coal, Warkworth steam coal, and Pasir subbituminous coal) with 1-methylnaphthalene (1-MN) at 360, 380, and 400{sup o}C. The effects of blending these HPCs into standard coal blends were investigated. Blending HPCs as 5-10% of a standard blend (Kouryusho:Goonyella:K9) enhanced the thermoplasticity over a wide temperature range. For blends made with the Pasir-HPC, produced from a noncaking coal, increasing the extraction temperature from 360 to 400{sup o}C increased the thermoplasticity significantly. Blends containing Warkworth-HPC, produced from a slightly caking coal, had a higher tensile strength than the standard blend in semicoke strength tests. The addition of 10% Pasir-HPC, extracted at 400{sup o}C, increased the tensile strength of the semicokes to the same degree as those made with Gregory-HPC. Furthermore, all HPC blends had a higher tensile strength and smaller weight loss during carbonization. These results suggest that the HPC became integrated into the coke matrix, interacting strongly with the other raw coals. 14 refs., 11 figs., 1 tab.

    A USEPA procedure, ISCLT3 (Industrial Source Complex Long-Term), was applied to model the spatial distribution of polycyclic aromatic hydrocarbons (PAHs) emitted from various sources including coal, petroleum, natural gas, and biomass into the atmosphere of Tianjin, China. Benzo(a)pyrene equivalent concentrations (BaPeq) were calculated for risk assessment. Model results were provisionally validated for concentrations and profiles based on the observed data at two monitoring stations. The dominant emission sources in the area were domestic coal combustion, coke production, and biomass burning. Mainly because of the difference in the emission heights, the contributions of various sources to the average concentrations at receptors differ from proportions emitted. The shares of domestic coal increased from {approximately} 43% at the sources to 56% at the receptors, while the contributions of coking industry decreased from {approximately} 23% at the sources to 7% at the receptors. The spatial distributions of gaseous and particulate PAHs were similar, with higher concentrations occurring within urban districts because of domestic coal combustion. With relatively smaller contributions, the other minor sources had limited influences on the overall spatial distribution. The calculated average BaPeq value in air was 2.54 {+-} 2.87 ng/m{sup 3} on an annual basis. Although only 2.3% of the area in Tianjin exceeded the national standard of 10 ng/m{sup 3}, 41% of the entire population lives within this area. 37 refs., 9 figs.

    High-temperature {sup 1}H NMR and rheometry measurements were carried out on 4:1 wt/wt blends of a medium volatile bituminous coal with two anthracites, two petroleum cokes, charcoal, wood, a low-temperature coke breeze, tyre crumb, and active carbon to determine the effects on fluidity development to identify the parameters responsible for these effects during pyrolysis and to study possible relationships among the parameters derived from these techniques. Positive, negative, and neutral effects were identified on the concentration of fluid material. Small positive effects (ca. 5-6%) were caused by blending the coal with petroleum cokes. Charcoal, wood, and active carbon all exerted negative effects on concentration (18-27% reduction) and mobility (12-25% reduction in T2) of the fluid phase, which have been associated with the inert character and high surface areas of these additives that adsorb the fluid phase of the coal. One of the anthracites and the low-temperature coke breeze caused deleterious effects to a lesser extent on the concentration (7-12%) and mobility (13-17%) of the fluid material, possibly due to the high concentration of metals in these additives (ca. 11% ash). Despite the high fluid character of tyre crumb at the temperature of maximum fluidity of the coal (73%), the mobility of the fluid phase of the blend was lower than expected. The comparison of {sup 1}H NMR and rheometry results indicated that to account for the variations in minimum complex viscosity for all the blends, both the maximum concentration of fluid phase and the maximum mobility of the fluid material had to be considered. For individual blends, two exponential relationships have been found between the complex viscosity and the concentration of solid phase in both the softening and resolidification stages but the parameters are different for each blend. 30 refs., 8 figs., 5 tabs.

    We have studied the reaction of ethanol and water over NiCeO2-x(111) model surfaces to elucidate the mechanistic steps associated with the ethanol steam reforming (ESR) reaction. Our results provide insights about the importance of hydroxyl groups to the ESR reaction over Ni-based catalysts. Systematically, we have investigated the reaction of ethanol on NiCeO2-x(111) at varying Ce? concentrations (CeO1.82.0) with absence/presence of water using a combination of soft X-ray photoelectron spectroscopy (sXPS) and temperature-programmed desorption (TPD). Consistent with previous reports, upon annealing, metallic Ni formed on reduced ceria while NiO was the main component on fully oxidized ceria. Ni? is the active phase leading to both the CC and CH cleavage of ethanol but is also responsible for carbon accumulation or coking. We have identified a Ni?C phase that formed prior to the formation of coke. At temperatures above 600K, the lattice oxygen from ceria and the hydroxyl groups from water interact cooperatively in the removal of coke, likely through a strong metalsupport interaction between nickel and ceria that facilitates oxygen transfer.

    Banerjee, K.; O`Toole, T.J.

    1995-12-01

    A hazardous waste landfill adjacent to a coke manufacturing facility was in operation between July 1990 and December 1991. A system was constructed to collect and treat the leachate from the landfill prior to discharge to the river. Occasionally, the discharge from the treatment facility exceeded the permit limitations for Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Organic Carbon (TOC). The objectives of this study were to determine treatment methods which would enable compliance with the applicable discharge limits; to establish the desired operating conditions of the process; and to investigate the effect of various parameters such as pH, catalyst dosage, and reaction time on the COD destruction efficiency. The characteristics of the landfill leachate in question were significantly variable in terms of chemical composition. A review of the influent quality data suggests that the COD concentration ranges between 80 and 390 mg/l. The oxidation processes using Fenton`s reagent or a combination of UV/hydrogen peroxide/catalyst are capable of reducing the COD concentration of the leachate below the discharge limitation of 35 mg/l. The estimated capital cost associated with the Fenton`s reagent process is approximately $525,000, and the annual operating and maintenance cost is $560,000. The estimated capital cost for the UV/hydrogen peroxide/catalyst treatment system is $565,000. The annual operating and maintenance cost of this process would be approximately $430,000.

    Fast pyrolysis of biomass can be used to produce a raw bio-oil product, which can be upgraded by catalytic hydroprocessing to hydrocarbon liquid products. In this study the upgraded products were distilled to recover light naphtha and oils and to produce a distillation resid with useful properties for coker processing and production of renewable, low-sulfur electrode carbon. For this hydroprocessing work, phase separation of the bio-oil was applied as a preparatory step to concentrate the heavier, more phenolic components thus generating a more amenable feedstock for resid production. Low residual oxygen content products were produced by continuous-flow, catalytic hydroprocessing of the phase separated bio-oil.

    Risk Management Programs for Chemical Accidental Release Prevention is the name of the proposed rule for the RMP Risk Management Program. The RMP was written in response to several catastrophic releases of hazardous substances. The rule is applicable to facilities that store, process or use greater than threshold quantities of 62 listed flammable chemicals and another 100 listed toxic substances. Additionally, a Risk Management Plan is registered with the EPA, Chemical Safety and Hazardous Investigation Board, state governments and the local emergency planning commission. The Clean Air Act Amendments of 1990 (specifically Section 112r) required the EPA to develop a three phase Risk Management Plan for industry: prevention program; hazard assessment; and emergency response program. The Prevention Program closely follows the OSHA`s Process Safety Management Standard. The Hazard Assessment section requires facilities to develop plans for a worst case scenario. The Emergency Response section defines the steps the facility and each employee will take if a release occurs. This section also needs to be coordinated with the Local Emergency Planning Commission. These regulations are described using Clairton Works as an example of compliance.

    The atomic-scale processes that control the formation of carbon deposits on Ni catalysts in reforming applications are poorly understood. Ab initio Density Functional Theory calculations have been used to examine several key elementary steps in the complex network of chemical reactions that precedes carbon formation on practical catalysts. Attention has been focused on the disproportionation of CO. A comparative study of this reaction on flat and stepped crystal planes of Ni has provided the first direct evidence that surface carbon formation is driven by elementary reactions occurring at defect sites on Ni catalysts. The adsorption and diffusion of atomic H on several flat and stepped Ni surfaces has also been characterized experimentally.

    The blast furnace raceway shows different characteristics with PCR (pulverized coal injection rate). It was found in this study that with the increase of PCR the raceway depth decreases, and the size of birds nest and sometimes with liquid holdup, increases. Oxygen enrichment with co-axial lances was known to be very effective on the extension of raceway depth and size reduction of birds nest. It was also found that there are various factors which affect the coke properties at tuyere level of the blast furnace. Coke traveling time was calculated to be extended with PCR and it had a close relationship with the coke size in bosh. Coke mean size decreased with the increase of coke traveling time, that is, with the increase of PCR. Both DI (the strength of coke in cold) and CSR (the strength of coke after reaction) were also decreased with PCR. RAFT (Raceway Adiabatic Flame Temperature) had a tendency to be decreased with the increase of PCR, which is obtained by the estimation of coke temperature via XRD analysis. From the analysis of alkali contents in coke sampled along the radius of the blast furnace, it was understood that no difference in alkali contents between fine and lump coke represents that coke fines generated from upper burden might appear at tuyere level.

    The flow of molten iron in the hearth of blast furnace was investigated by using a water model test and a numerical simulation. The water model apparatus was set up in order to evaluate the effects of coke size, coke bed structure, drain rate, and coke free space on the fluidity of molten iron through measurement of residence time and visualization of flow pattern. In addition, the flow was calculated by solving momentum equation in porous media using finite element method. The residence time increased with the coke size decrease, but decreased with the drain rate increase. If small coke was placed in the center of deadman, peripheral flow was enhanced. The flow path was changed due to the coke free space.

    In Kashima Steel Works, 25-year-old 7-meter-high coke ovens have damage on their walls. However, by using new methods of internal in-situ investigation, ceramic welding for the extended central and upper portions of coke ovens has prolonged the campaign life for over 40 years without large-scale hot repair. In this paper, introduction of these new methods, its application in Kashima and the policy of repairing the tall coke oven are reported.

    In the foundry industry, the recarburizing materials used can range from high purity graphite to chars. The dissolution performance of recarburizing materials is critical to the industry, as it has a direct bearing on productivity. In this study, the dissolution performance of a variety of clean Auscarb carbon materials has been determined to assess their suitability as recarburizing material. The carbon sources investigated were graphite (synthetic), coke A (2.5 and 18 hr), coke B (2.5, 3 and 18 hr) and coke C (2.5 hr). In addition, the effect of melt sulfur content and coke supplier (ACIRL or CSIRO laboratories) on dissolution performance was examined. Dissolution performance was characterized on the basis of the measured rate constant. The experimental investigation conducted in this study has established the trend in performance of the carbons. The results show that, for a fixed melt sulfur content of 0.2%, synthetic graphite was the best, although the dissolution performance of coke B approaches half that of synthetic graphite. The performance of cokes A and C fall slightly behind that of coke B. The cokes supplied from different sources were found to have similar dissolution performance only on extended coking times. Decreased melt sulfur content was found to increase the dissolution rate, and it was found that the extent of improvement was influenced by the nature of the carbonaceous material.

    1995-12-01

    SSAB operates a coke oven plant in Luleaa, Sweden, consisting of one 7 m battery. Pushing the first coke in 1975, the battery encountered over the years more and more difficulties in keeping coking time and operation level at the design rate. In order to improve the coke supply a major repair of the battery was made. In 1989 the battery was fully rehabilitated by Krupp Koppers. The experience made during the years before and during repair contributed to a new policy for the operation of the plant. The policy has led to considerable improvements. It is clear that it is possible to successfully operate a rehabilitated battery.

    This project deals with the demonstration of a coking process using proprietary technology of Calderon, with the following objectives geared to facilitate commercialization: (i) making coke of such quality as to be suitable for use in hard-driving, large blast furnaces; (ii) providing proof that such process is continuous and environmentally closed to prevent emissions; (iii) demonstrating that high-coking-pressure (non-traditional) coal blends which cannot be safely charged into conventional by-product coke ovens can be used in the Calderon process; and (iv) demonstrating that coke can be produced economically, at a level competitive with coke imports. The activities of the past quarter were focused on the following: ? Consolidation of the project team-players; ? Recruiting Koppers Industries as an additional stakeholder; ? Developing a closed system for the production of binder pitch from tar in the Calderon coking process as the incentive for Koppers to join the team; ? Gathering appropriate equipment for conducting a set of experiments at bench scale to simulate tar quality produced from the Calderon coking process for the production of binder pitch; and ? Further progress made in the design of the commercial coking reactor.

  13. Refines Efficiency Improvement

    SciTech Connect (OSTI)

    WRI

    2002-05-15

    Refinery processes that convert heavy oils to lighter distillate fuels require heating for distillation, hydrogen addition or carbon rejection (coking). Efficiency is limited by the formation of insoluble carbon-rich coke deposits. Heat exchangers and other refinery units must be shut down for mechanical coke removal, resulting in a significant loss of output and revenue. When a residuum is heated above the temperature at which pyrolysis occurs (340 C, 650 F), there is typically an induction period before coke formation begins (Magaril and Aksenova 1968, Wiehe 1993). To avoid fouling, refiners often stop heating a residuum before coke formation begins, using arbitrary criteria. In many cases, this heating is stopped sooner than need be, resulting in less than maximum product yield. Western Research Institute (WRI) has developed innovative Coking Index concepts (patent pending) which can be used for process control by refiners to heat residua to the threshold, but not beyond the point at which coke formation begins when petroleum residua materials are heated at pyrolysis temperatures (Schabron et al. 2001). The development of this universal predictor solves a long standing problem in petroleum refining. These Coking Indexes have great potential value in improving the efficiency of distillation processes. The Coking Indexes were found to apply to residua in a universal manner, and the theoretical basis for the indexes has been established (Schabron et al. 2001a, 2001b, 2001c). For the first time, a few simple measurements indicates how close undesired coke formation is on the coke formation induction time line. The Coking Indexes can lead to new process controls that can improve refinery distillation efficiency by several percentage points. Petroleum residua consist of an ordered continuum of solvated polar materials usually referred to as asphaltenes dispersed in a lower polarity solvent phase held together by intermediate polarity materials usually referred to as resins. The Coking Indexes focus on the amount of these intermediate polarity species since coke formation begins when these are depleted. Currently the Coking Indexes are determined by either titration or solubility measurements which must be performed in a laboratory. In the current work, various spectral, microscopic, and thermal techniques possibly leading to on-line analysis were explored for measuring the Coking Indexes.

    Determination of the best furnace for a commercial coke plant is underway. A shuttle or tunnel kiln has economic advantage over a rotary hearth design. Production of 20 tons of coke in a small shuttle kiln is near completion which will provide experience for this design. Twenty tons of CTC continuous coke are being produced for testing at a General Motors` foundry. The production is approximately 75 percent complete. During this production, variables of the process are being studied to aid in design of a commercial coke plant. Raw material composition, blending, briquetting variables, and calcining heat profile are the major areas of interest. Western SynCoal Company produces a dried coal product from sub-bituminous coal. This upgraded product was evaluated for producing coke products by blending char from this coal product with the coal product along with suitable binders. The green briquettes were then calcined to produce coke. The resulting coke was judged to be usable as part of a cupola coke charge or as a fuel in cement kilns and sugar beet furnaces.

    1996-12-31

    Char, the major co-product of mild coal gasification, represents about 70 percent of the total product yield. The only viable use for the char is in the production of formed coke. Early work to develop formed coke used char from a pilot plant sized mild gasification unit (MGU), which was based on commercial units of the COALITE plant in England. Formed coke was made at a bench-scale production level using MGU chars from different coals. An evolutionary formed coke development process over a two-year period resulted in formed coke production at bench-scale levels that met metallurgical industries` specifications. In an ASTM D5341 reactivity test by a certified lab, the coke tested CRI 30.4 and CSR 67.0 which is excellent. The standard is CRI < 32 and CSR > 55. In 1991, a continuous 1000 pounds per hour coal feed mild coal gasification pilot plant (CMGU) was completed. The gasification unit is a heated unique screw conveyor designed to continuously process plastic coal, vent volatiles generated by pyrolysis of coal, and convert the plastic coal to free flowing char. The screw reactor auxiliary components are basic solids materials handling equipment. The screw reactor will convert coal to char and volatile co-products at a rate greater than 1000 pounds per hour of coal feed. Formed coke from CMGU char is comparable to that from the MGU char. In pilot-plant test runs, up to 20 tons of foundry coke were produced. Three formed coke tests at commercial foundries were successful. In all of the cupola tests, the iron temperature and composition data indicated that the formed coke performed satisfactorily. No negative change in the way the cupola performed was noticed. The last 20-ton test was 100 percent CTC/DOE coke. With conventional coke in this cupola charging rates were 10 charges per hour. The formed coke charges were 11 to 12 charges per hour. This equates to a higher melt rate. A 10 percent increase in cupola production would be a major advantage. 13 figs., 13 tabs.

    Fuel injection at the tuyeres has always been part of normal operating practice on this blast furnace. It has been used as much because of the beneficial effects on furnace operation as for the replacement of some of the coke that would otherwise be consumed. Fuel oil was used at first, but since the early 1980s it was more economical to inject natural gas. Studies in 1990 indicated that natural gas could be increased to 75 kg/tHM on No. 7 Furnace, and this would result in a coke rate of approximately 360 kg/tHM. It was apparent that coal injection offered significantly more opportunity for coke savings. Coke rate could be lowered to 300 kg/tHM with coal injected at 175 kg/tHM. Some combustion limitations were expected at that level. A coke rate of 270 kg/tHM with coal at 200 kg/tHM may be possible once these limitations are overcome. Furnace permeability was expected to limit the ability to reduce coke rate any further. In addition, the relative cost of coal would be significantly lower than the cost of coke it replaced. This lead to the decision late in 1991 to install pulverized coal injection (PCI) equipment for all of Inland`s blast furnaces. This paper will deal with PCI experience at No. 7 Blast Furnace.

    Kennedy, Charles R. (Oak Ridge, TN)

    1980-01-01

    An improved method for fabricating a graphite article comprises the steps of impregnating a coke article by first heating the coke article in contact with a thermoplastic pitch at a temperature within the range of 250.degree.-300.degree. C. at a pressure within the range of 200-2000 psig for at least 4-10 hours and then heating said article at a temperature within the range of 450.degree.-485.degree. C. at a pressure of 200-2000 psig for about 16-24 hours to provide an impregnated article; heating the impregnated article for sufficient time to carbonize the impregnant to provide a second coke article, and graphitizing the second coke article. A graphite having improved thermal stress resistance results when the coke to be impregnated contains 1-3 wt.% sulfur and no added puffing inhibitors. An additional improvement in thermal stress resistance is achieved when the second coke article is heated above about 1400.degree. C. at a rate of at least 10.degree. C./minute to a temperature above the puffing temperature.

  11. Pellet property requirements for future blast-furnace operations and other new ironmaking processes

    SciTech Connect (OSTI)

    Agrawal, A.K.; Oshnock, T.W.

    1995-12-01

    The requirements for the physical, chemical and metallurgical properties of pellets have continued to become more stringent as blast-furnace productivity and coke rate have been rapidly improved during the last decade. In addition, the age and deterioration of the North American coke batteries, the lack of capital to sufficiently rebuild them, and the threat of increasingly more stringent environmental controls for the coke batteries has forced North American ironmakers to begin implementing pulverized coal injection to minimize the coke requirements for the blast furnace and to seriously investigate developing other ironmaking processes that use coal instead of coke. Therefore, the next major step in North American ironmaking has included injecting pulverized coal (PC) at 200 kilograms per ton of hot metal (kg/ton) [400 pounds per net ton of hot metal (lb/NTHM)] or greater which will result in the coke rate decreasing to less than 300 kg/ton (600 lb/NTHM) or less. As a result, the pellets will spend more time in the furnace and will be required to support more total weight. Pellets can also be a major iron unit source for other cokeless ironmaking processes such as the COREX process or the AISI direct ironmaking process. This paper will explore the pellet property requirements for future blast-furnace operations and cokeless ironmaking processes.

    1993-01-01

    Recently, global environmental protection has been a great concern in the world. In the United States of America, the Clean Air Act (CAA) has been revised to control emissions strictly. Especially in the field of cokemaking, the restriction of fume emission from a coke oven is so severe that old coke ovens will stop operation with the application of CAA. In Japan, it is expected that more severe protection measures are going to be requested for keeping environmental quality. In this situation, it is indispensable to strengthen environmental protection measures for cokemaking plants to continue coke production in the 21st century. In Chiba Works, Kawasaki Steep Corp., the Ironmaking Department has been struggling for the improvement of environmental measures for. These activities for coke ovens are described in this report. The paper describes fume emission control from the coke oven door and dust emission control measures, including the dust monitoring system, prevention of secondary dust scattering from coke ovens, replacement of dedusters, and fume and dust control of stack emission.

  13. The effect of feedstock additives on FCC catalyst deactivation

    SciTech Connect (OSTI)

    Hughes, R.; Koon, C.L.; McGhee, B.

    1995-12-31

    Fluid catalytic cracking is a major petroleum refining process and because of this the deactivation of FCC catalysts by coke deposition has been the subject of considerable investigation during the past 50 years. Nevertheless, a lack of understanding of the fundamental understanding of processes leading to coke formation still exists. Basic studies using Zeolites have usually involved excessively high levels of coke deposits compared to normal FCC operation. The present study addresses coke formation at realistic levels of 0.5 to 1.0% w/w using a standard MAT reactor in which concentrations of 1% and 10% of various additives were added to the n-hexadecane feedstock. These additives included, quinoline, phenanthrene, benzofuran, thianaphthene and indene. The coke formed was characterised by mass spectrometry and was significantly aliphatic in nature, the amount formed increasing in the order quinoline, phenanthrene, thianaphthene, benzofuran, indene. Quinoline acts primarily as a poison, whereas the other additives tend to promote coke formation in n-hexadecane cracking.

    1990-10-01

    Bethlehem Steel Corporation (BSC), of Bethlehem, Pennsylvania, has requested financial assistance from DOE for the design, construction, and operation of a 2800-ton-per-day blast furnace granulated coal injection (BFGCI) system for each of two existing iron-making blast furnaces. The blast furnaces are located at BSC's facilities in Burns Harbor, Indiana. BFGCI technology involves injecting coal directly into an iron-making blast furnace and subsequently reduces the need for coke on approximately a pound of coke for pound of coal basis. BFGCI also increases blast furnace production. Coke will be replaced with direct coal injection at a rate of up to 400 pounds per NTHM. The reducing environment of the blast furnace enables all of the sulfur in the coal to be captured by the slag and hot metal. The gases exiting the blast furnace are cleaned by cyclones and then wet scrubbing to remove particulates. The cleaned blast furnace gas is then used as a fuel in plant processes. There is no measurable sulfur in the off gas. The primary environmental benefits derived from blast furnace coal injection result from the reduction of coke requirements for iron making. Reduced coke production will result in reduced releases of environmental contaminants from coking operations. 5 figs.

  15. Petropower energia project under way in Chile promises refiner better economics at lower cost

    1996-12-31

    Construction of the Republic of Chile`s first public/private industrial partnership project is well under way. Ground was broken for the $232-million Petropower Energia Limitada project early this year, shortly after the final contract between the parties - Foster Wheeler Power Systems, Inc. (FWPS); Petrox S.A. Refineria de Petroleo and Empresa Nacional del Petroleo (ENAP) - was signed. The Petropower project, located adjacent to Petrox`s 84,000-b/d refinery in Talcahuano, represents the first project ever to combine petroleum coking technology with cogeneration technology in a single project financing. Petropower is 85% owned by FWPS, 7.5% by ENAP, the Chilean national oil company and parent of Petrox S.A. When completed in mid-1998, the Petropower project will enable Petrox to refine heavier crudes and enhance the refinery`s flexibility and economics. The project will consist of a delayed coking facility (a 12,000-b/d delayed coking unit and a 7,000-b/d hydrotreating plant) and a 67-MW (59 MW net) cogeneration plant. The coke produced will fuel a Foster Wheeler proprietary-design circulating fluidized-bed (CFB) boiler which will generate all the high-pressure steam and electric power needs of the Petrox refinery. This unit will be the first circulating fluidized-bed boiler to be built in Latin America. The cogeneration facility, using limestone as a reagent and equipped with a baghouse, will control SO{sub x} emissions from combustion of the green coke fuel and easily meet all Chilean environmental standards. Moreover, by constructing the cogeneration facility, Petrox will not have to proceed with capital improvements to existing facilities to ensure a reliable source of steam and electricity, resulting in substantial savings for Petrox. The cogeneration plant provides a permanent {open_quotes}disposal{close_quotes} for all coke produced by the delayed coker, thereby solving any future problems of unwanted or excess coke.

  16. Blast Furnace Granulated Coal Injection

    SciTech Connect (OSTI)

    1998-09-30

    Production levels on each furnace exceeded 7000 NTHM/day during July. The combined production of 14,326 was a result of lower coke rates and below average delay rates on both furnaces, The combined production was at its highest level since September 1997. In August, the combined productivity declined to less than 13,500 NTHM/day. Although D furnace maintained a production rate in excess of 7000 NTHM/day, C furnace was lower because of a castfloor breakout and subsequent five day repair from August 26-30. Despite the lower productivity in August, injected coal and furnace coke rates were very good during the month. During September, the operation was difficult as a result of higher delays on both furnaces. The combined average monthly delay rate was considerably above the twenty-month average of 113 minutes per day and the combined average monthly production was less than 14,000 NTHM/day. Higher furnace coke rates at lower coal injection levels also contributed to the decrease. Additionally, the coke rate on both furnaces was increased substantially and the injected coal rate was decreased in preparation for the high volatile Colorado coal trial that started on September 28. The furnace process results for this quarter are shown in Tables 1A and 1B. In addition, the last twelve months of injected coal and coke rates for each furnace are shown in Figures 1 and 2.

    A mathematical model was developed to permit study of the behavior of fuel-oil droplets in a combustion chamber, and results are presented from a computer calculation performed for the 300-MW model TGMP-314P boiler of a power plant. The program written to perform the calculations was organized so that the first stage would entail calculation of the combustion (vaporization) of a droplet of liquid fuel. The program then provided for a sudden decrease in the mass of the fuel particle, simulating rupture of the coke shell and ejection of some of the liquid. The program then considered the combustion of a hollow coke particle. Physicochemical parameters characteristic of fuel oil M-100 were introduced in the program in the first stage of computations, while parameters characteristic of the coke particle associated with an unburned fuel-oil droplet were included in the second stage.

    1995-12-01

    Number 13 Blast Furnace at Gary began injecting Pulverized Coal in March 1993. The injection level was increased over the next nine months until a level off 409 lbs/THM was achieved for the month of December 1993. Several major areas were critical in achieving this high level of Pulverized coal injection (PCI) including furnace conditions, lance position, tuyere blockage, operating philosophy, and outages. The paper discusses the modifications made to achieve this level of injection. This injection level decreased charged dry coke rate from 750 lbs/THM to about 625 lbs/THM, while eliminating 150 lbs/THM of oil and 20 lbs/THM of natural gas. Assuming a 1.3 replacement ratio for an oil/natural gas mixture, overall coke replacement for the coal is about 0.87 lbs coke/lbs coal. Gary Works anticipates levels of 500 lbs/THM are conceivable.

  19. Control of cooling losses at high pulverized coal injection rates

    SciTech Connect (OSTI)

    Bonte, L.; Nieuwerburgh, H. Van

    1996-12-31

    One of the problems which is encountered by many blast furnace operators is the appropriate control of the cooling losses of the blast furnace. This problem has been aggravated by the introduction of pulverized coal injection. Even with equal burden and coke composition, both Sidmar furnaces behave differently with respect to the cooling losses. This phenomenon is possibly attributable to the different profile and cooling circuitry of the furnaces. Among other parameters the angles of bosh and stack may favor the formation of scabs or not. Some operators experience a decrease of their cooling losses, other operators have problems to limit their cooling losses to an acceptable level. As a result, different operating practices exist with respect to the burden distribution. The increase of the ore to coke ratio with pulverized coal injection suggests that the coke and sinter quality has to be monitored very carefully in order to avoid permeability problems.

    Catalysts for the dehydrogenation of light alkanes were prepared by dispersing Pt on the surface of a calcined hydrotalcite-like support containing indium, Mg(In)(Al)O. Upon reduction in H{sub 2} at temperatures above 673 K, bimetallic particles of PtIn are observed by TEM, which have an average diameter of 1 nm. Analysis of Pt LIII-edge extended X-ray absorption fine structure (EXAFS) data shows that the In content of the bimetallic particles increases with increasing bulk In/Pt ratio and reduction temperature. Pt LIII-edge X-ray absorption near edge structure (XANES) indicates that an increasing donation of electronic charge from In to Pt occurs with increasing In content in the PtIn particles. The activity and selectivity of the Pt/Mg(In)(Al)O catalysts for ethane and propane dehydrogenation reactions are strongly dependent on the bulk In/Pt ratio. For both reactants, maximum activity was achieved for a bulk In/Pt ratio of 0.48, and at this In/Pt ratio, the selectivity to alkene was nearly 100%. Coke deposition was observed after catalyst use for either ethane or propane dehydrogenation, and it was observed that the alloying of Pt with In greatly reduced the amount of coke deposited. Characterization of the deposit by Raman spectroscopy indicates that the coke is present as highly disordered graphite particles <30 nm in diameter. While the amount of coke deposited during ethane and propane dehydrogenation are comparable, the effects on activity are dependent on reactant composition. Coke deposition had no effect on ethane dehydrogenation activity, but caused a loss in propane dehydrogenation activity. This difference is attributed to the greater ease with which coke produced on the surface of PtIn nanoparticles migrates to the support during ethane dehydrogenation versus propane dehydrogenation.

    Improvements in Heavy oils conversion imply sulfur compounds. For medium conversion, side polycondensations and coke production were avoided by Hydrogen diluent donors (HDD), but conversions were partially inhibited. Sulfided radical activators used in association with HDD and H{sub 2} pressure overcome this effect by preventing coke formation up to 50-60% conversion into 500{degrees}C{sup -} light fractions with unchanged quality profile. Deeper conversions require dispersed sulfided catalyst. Phosphomolybdic acid or molybdenum naphtenate have been used as soluble precursors for such treatments. The state and fitness of sulfidation depend on the nature of precursors.

    There is described an improved coal liquefaction quenching process which prevents the formation of coke with a minimum reduction of thermal efficiency of the coal liquefaction process. In the process, the rapid cooling of the liquid/solid products of the coal liquefaction reaction is performed without the cooling of the associated vapor stream to thereby prevent formation of coke and the occurrence of retrograde reactions. The rapid cooling is achieved by recycling a subcooled portion of the liquid/solid mixture to the lower section of a phase separator that separates the vapor from the liquid/solid products leaving the coal reactor.

    To facilitate the positional cloning of the breast-ovarian cancer gene BRCA1, the authors constructed a high-density genetic map of the 8.3-cM interval between D17S250 and GIP on chromosome 17q12-q21. Markers were mapped by linkage in the CEPH and in extended kindreds in the breast cancer series. The map comprises 33 ordered polymorphisms, including 12 genes and 21 anonymous markers, yielding an average of one polymorphism every 250 kb. Twenty-five of the markers are PCR-based systems. The order of polymorphic genes and markers is cen-D17S250-D17S518-HER2-THRA1-RARA-D17S80-KRT10-[D17S800-D17S857]-GAS-D17S856-EDH17B-D17S855-D17S859-D17S858-[PPY-D17S78]-D17S183-EPB3-D17S579-D17S509-[D17S508-D17S190 = D17S810]-D17S791-[D17S181 = D17S806]-D17S797-HOX2B-GP3A-[D17S507 = GIP]-qter. BRCA1 lies in the middle of the interval, between THRA1 and D17S183. Markers from this map can be used to determine whether cancer is linked to BRCA1 in families, to evaluate whether tumors have lost heterozygosity at loci in the region, and to identify probes for characterizing chromosomal rearrangements from patients and from tumors. 21 refs., 1 fig., 3 tabs.

    Throughout the years the blast-furnace process has been improved upon significantly. Increases to the hot-blast temperature, improvements to the physical, chemical, and metallurgical properties of coke and burden materials, the use of more fuel injectants, and improvements to the design of the furnace facilities have led to significant decreases in furnace coke rate, increases in productivity, and increases in furnace campaign life. As a result, many of the alternative cokeless reduction processes have not replaced blast-furnace hot-metal production in North America. In the future, these continued blast-furnace improvements will potentially result in coke rates decreasing to 400 pounds per net ton of hot metal (lb/NTHM) as more pulverized coal is injected. These improvements, coupled with the fact that existing blast furnaces and coke plants can be refurbished for approximately $110 per annual ton of hot metal [$100 per annual net ton of hot metal (NTHM)], will result in extending the life of the North American blast furnaces well into the twenty-first century.

    Catalytic performance and the nature of surface adsorbates were investigated for high-surface-area ceria during ethylbenzene oxidative dehydrogenation (ODH) reaction using CO2 as a soft oxidant. A template assisted method was used to synthesize the high-surface-area ceria. The interactions between ethylbenzene, styrene and CO2 on the surface of ceria and the role of CO2 for the ethylbenzene ODH reaction have been investigated in detail by using activity test, in situ Diffuse Reflectance Infrared and Raman spectroscopy. Not only did CO2 as an oxidant favor the higher yield of styrene, but it also inhibited the deposition of coke during the ethylbenzene ODHmore » reaction. Ethylbenzene ODH reaction over ceria followed a two-step pathway: Ethylbenzene is first dehydrogenated to styrene with H2 formed simultaneously, and then CO2 reacts with H2 via the reverse water gas shift. The styrene produced can easily polymerize to form polystyrene, a key intermediate for coke formation. In the absence of CO2, the polystyrene transforms into graphite-like coke at temperatures above 500 °C, which leads to catalyst deactivation. While in the presence of CO2, the coke deposition can be effectively removed via oxidation with CO2.« less

    This Department of Energy National Energy Technology Laboratory sponsored research effort to develop environmentally cleaner projects as a spin-off of the FutureGen project, which seeks to reduce or eliminate emissions from plants that utilize coal for power or hydrogen production. New clean coal conversion processes were designed and tested for coproducing clean pitches and cokes used in the metals industry as well as a heavy crude oil. These new processes were based on direct liquefaction and pyrolysis techniques that liberate volatile liquids from coal without the need for high pressure or on-site gaseous hydrogen. As a result of the research, a commercial scale plant for the production of synthetic foundry coke has broken ground near Wise, Virginia under the auspices of Carbonite Inc. This plant will produce foundry coke by pyrolyzing a blend of steam coal feedstocks. A second plant is planned by Quantex Energy Inc (in Texas) which will use solvent extraction to coproduce a coke residue as well as crude oil. A third plant is being actively considered for Kingsport, Tennessee, pending a favorable resolution of regulatory issues.

    An evaluation of environmental conditions and possible health effects among workers exposed to coke dust was conducted. Personal breathing-zone (PBZ) concentrations of total airborne dust ranged from 0.1 to 12 milligrams/cubic meter (mg/m3) with a median of 1.6 mg/m3; mass median particle diameter was about 8 micrometers. Very high PBZ concentrations of coke dust occurred during a semimonthly cleanup of underground coke pits; levels ranged from 98 to 190mg/m3 with a mean of 140mg/m3. Oil mists were not detected. Exposures to polynuclear aromatic compounds were below the analytical limit of detection among workers for routine jobs. Abnormal pulmonary function tests were found in 12% of those tested. Five cases of chronic bronchitis and seven of chronic cough, 10 and 13% respectively, were identified among those interviewed. The authors conclude that there were potentially hazardous exposures to high dust levels during semimonthly coke-pit cleaning jobs.

    2012-03-06

    The objective of the project is to develop and demonstrate a novel fluidized-bed process module called a ?¢????Therminator?¢??? to simultaneously destroy and/or remove tar, NH3 and H2S from raw syngas produced by a fluidized-bed biomass gasifier. The raw syngas contains as much as 10 g/m3 of tar, 4,000 ppmv of NH3 and 100 ppmv of H2S. The goal of the Therminator module would be to use promising regenerable catalysts developed for removing tar, ammonia, and H2S down to low levels (around 10 ppm). Tars are cracked to a non-condensable gas and coke that would deposit on the acid catalyst. We will deposit coke, much like a fluid catalytic cracker (FCC) in a petroleum refinery. The deposited coke fouls the catalyst, much like FCC, but the coke would be burned off in the regenerator and the regenerated catalyst would be returned to the cracker. The rapid circulation between the cracker and regenerator would ensure the availability of the required amount of regenerated catalyst to accomplish our goal. Also, by removing sulfur down to less than 10 ppmv, NH3 decomposition would also be possible in the cracker at 600-700???°C. In the cracker, tar decomposes and lays down coke on the acid sites of the catalyst, NH3 is decomposed using a small amount of metal (e.g., nickel or iron) catalyst incorporated into the catalyst matrix, and H2S is removed by a small amount of a metal oxide (e.g. zinc oxide or zinc titanate) by the H2S-metal oxide reaction to form metal sulfide. After a tolerable decline in activity for these reactions, the catalyst particles (and additives) are transported to the regenerator where they are exposed to air to remove the coke and to regenerate the metal sulfide back to metal oxide. Sulfate formation is avoided by running the regeneration with slightly sub-stoichiometric quantity of oxygen. Following regeneration, the catalyst is transported back to the cracker and the cycling continues. Analogous to an FCC reactor system, rapid cycling will allow the use of very active cracking catalysts that lose activity due to coking within the order of several seconds.

    The overall objective of this program is to develop mild gasification technology and co-product utilization. The objective of Task 3 was to investigate the necessary steps for upgrading the mild gasification char into potential high-market-value solid products. Recommendations of the Task 1 market survey section formed the basis for selecting three value-added solid products from mild gasification char: form coke, smokeless fuel, and activated adsorbent char. The formation and testing for the form coke co-product involved an evaluation of its briquette strength and reactivity. The measured tensile strength and reactivity of the form coke sample briquettes were in the range of commercial coke, and development tests on a larger scale are recommended. The reaction rate of the form coke carbon with carbon dioxide at 1825{degree}F was measured using a standard procedure. A smokeless fuel briquette with limestone added to control sulfur can be made from mild gasification char in a simple manner. Test results have shown that briquettes with limestone have a heating value comparable to other solid fuels and the limestone can retain up to 88% of the sulfur during combustion in a simple bench-scale combustion test, almost all of it as a stable calcium sulfate. Adsorbent chars were prepared with a standard steam activation procedure and tested for a variety of pertinent property and performance values. Such adsorbents may be better suited for use in some areas, such as the adsorption of low-molecular-weight substances, because of the smaller pore sizes measured in the char. 5 refs., 17 figs., 6 tabs.

    In 1989, an internal study in the Coke and Iron Maintenance Department identified the opportunities available to increase production, by decreasing unscheduled maintenance delays from 4.6%. A five year front loaded plan was developed, and presented to the company president. The plan required an initial investment of $1.4 million and a conservative break-even point was calculated to be 2.5 years. Due to budget restraints, it would have to be self-funded, i.e., generate additional production or savings, to pay for the program. The program began in 1991 at number 2 coke plant and the blast furnaces. This paper will describe the Iron Production Maintenance Effectiveness System (ME), which began with the mechanical and pipefitting trades.

    When the blast furnaces at SOLLAC/FOS were relined, the objective being to ensure a worklife of 15 years, it was decided that the iron making plant would be modernized at the same time: the coking plant has been overhauled and renovated and its coking time increased to ensure a worklife of at least 34 years. The surface area of the sinter strand was increased from 400 to 520 m{sup 2}, the burden preparation circuit were simplified, and pig iron production capacity increased from 4.2 to 4.5 million metric tons per year. Coal injection was developed so as to obtain 170 kg/t of pig iron, an expert system was added to ensure more efficient blast furnace operation, and new measures have been carried out for environmental protection. Since these heavy investments have been completed, SOLLAC/FOS is a high-performance iron making plant, allowing it to face new challenges in the future.

  13. Ironmaking Process Alternative Screening Study, Volume 1

    Iron in the United States is largely produced from iron ore mined in the United States or imported from Canada or South America. The iron ore is typically smelted in Blast Furnaces that use primarily iron ore, iron concentrate pellets metallurgical coke, limestone and lime as the raw materials. Under current operating scenarios, the iron produced from these Blast Furnaces is relatively inexpensive as compared to current alternative iron sources, e.g. direct iron reduction, imported pig iron, etc. The primary problem the Blast Furnace Ironmaking approach is that many of these Blast furnaces are relatively small, as compared to the newer, larger Blast Furnaces; thus are relatively costly and inefficient to operate. An additional problem is also that supplies of high-grade metallurgical grade coke are becoming increasingly in short supply and costs are also increasing. In part this is due to the short supply and costs of high-grade metallurgical coals, but also this is due to the increasing necessity for environmental controls for coke production. After year 2003 new regulations for coke product environmental requirement will likely be promulgated. It is likely that this also will either increase the cost of high-quality coke production or will reduce the available domestic U.S. supply. Therefore, iron production in the United States utilizing the current, predominant Blast Furnace process will be more costly and would likely be curtailed due to a coke shortage. Therefore, there is a significant need to develop or extend the economic viability of Alternate Ironmaking Processes to at least partially replace current and declining blast furnace iron sources and to provide incentives for new capacity expansion. The primary conclusions of this comparative Study of Alternative Ironmaking Process scenarios are: (1) The processes with the best combined economics (CAPEX and OPEX impacts in the I.R.R. calculation) can be grouped into those Fine Ore based processes with no scrap charge and those producing Hot Metal for charge to the EAF. (2) A pronounced sensitivity to Steel Scrap Cost was felt less by the Hot Metal Processes and the Fine Ore Processes that typically do not utilize much purchased scrap. (3) In terms of evolving processes, the Tecnored Process (and in particular, the lower-operating cost process with integral co-generation of electrical power) was in the most favorable groupings at all scrap cost sensitivities. (4) It should be noted also that the Conventional Blast Furnace process utilizing Non-Recovery coke (from a continuous coking process with integral co-generation of electrical power) and the lower-capital cost Mini Blast Furnace also showed favorable Relative Economics for the low and median Scrap Cost sensitivities. (5) The lower-cost, more efficient MauMee Rotary Hearth Process that uses a Briquetted Iron Unit Feed (instead of a dried or indurated iron ore pellet) also was in the most favorable process groupings. Those processes with lower-cost raw materials (i.e. fine ore and/or nonmetallurgical coal as the reductant) had favorable combined economics. In addition, the hot metal processes (in part due to the sensible heat impacts in the EAF and due to their inherently lower costs) also had favorable combined economics.

    In order to further develop the technology for high-rate pulverized coal injection (PCI), namely over 200 kg/t-pig, Nippon Steel performed a high injection rate test at the Kimitsu No. 3 blast furnace in November, 1993. The paper describes PCI equipment; the operational design of the test, including blast conditions, reducibility of sinter, coke strength and burden distribution; and test results. These results include a discussion of the transition of operation, burden distribution control, replacement ratio of coke, permeability at upper and lower parts of the furnace, reducibility at lower part of the furnace, accumulation of fines in the deadman, and generation and accumulation of unburnt char. Stable operation was achieved at a PCI rate of 190 kg/t-pig. With injection rates between 200--300 kg/t-pig, the problem becomes how to improve the reduction-meltdown behavior in the lower part of the furnace.

    There will be another blast furnace, the production capacity of which is 3.0 million tonnes per year in 1999 and mini mill plant, the production capacity of which is 1.8 million tonnes per year in 1996 at Kwangyang Works. Therefore, the coke oven gas and burnt lime will be deficient and more sinter will be needed. To meet with these situations, the authors modified the charging equipment and ignition furnace at Kwangyang No. 2 sinter plant in April 1995. After the modification of the charging equipment and ignition furnace, the consumption of burnt lime and coke oven gas could be decreased and the sinter productivity increased in spite of the reduction of burnt lime consumption. This report describes the operation results with the modification of the charging equipment and ignition furnace in No. 2 sinter plant Kwangyang works.

    Studies of Si transfer in blast furnaces have shown that the Si level in pig iron is influenced more by the reaction of silicon oxide gas generation in the raceway than the chemical reaction between hot metal and slag at the drop zone. Specifications require a Si content of pig iron below 0.15% at the Kwangyang Works, but the use of soft coking coal in the blend for coke ovens, high pulverized coal injection rate into the blast furnace, and the application of lower grade iron ore has resulted in the need to develop methods to control Si in hot metal. In this paper, the results of in furnace Si control and the desiliconization skills at the casthouse floor are described.

    Blast furnace ironmaking technology, by far the most important ironmaking process, is based on coke and iron ore pellets (or sinter) to produce liquid iron. However, there has been a worldwide effort searching for a more economical and environmental friendly alternative process for the production of liquid iron. The essential requirement is that it should be minimized in the usage of metallurgical coke and agglomerate of iron ore concentrates. With iron ore concentrate and coal as raw materials, there are two approaches: (a) Smelting reduction; melting the ore before reduction; (b) Reduction of the ore in solid state followed by melting. The present work is on the fundamentals of the latter. It consists of a better designed experimental study including pressure gradient measurement, and a more rigorous non-isothermal and non-isobaric mathematical model. Results of this work may be applied to carbothermic processes, such as FASTMET and LB processes, as well as recycling of fines in steel plants.

    1990-01-01

    AISI with co-funding from DOE has initiated a research and development program aimed at the development of a new process for direct steelmaking, and the program is discussed in this document. The project is expected to cost about $30 million over a three-year period, with the government providing approximately 77 percent of the funds and AISI the balance. In contrast to current steelmaking processes which are largely open and batch, the direct steelmaking process would be closed and continuous. Further, it would use coal directly, thereby avoiding the need for coke ovens. It is thought that this new process, if successful, would have significant capital and operating cost benefits. Further, there would be important energy savings and environmental benefits, primarily as a result of the elimination of coke ovens. 10 refs., 1 fig., 2 tabs.

    The surface properties of several well-characterized commercial carbon materials were modified by thermal and chemical treatments. The reversible capacities for lithium intercalation of a sponge green coke and a fuel green coke for lithium intercalation increased by as much as 25% after heat treatment in both reducing (5% H{sub 2}/Ar) and oxidizing (CO{sub 2}) environments. The irreversible capacity loss increased significantly with CO{sub 2} treatment at 800{degrees}C. The trend of larger capacity losses with CO{sub 2} treatment is also observed with a synthetic graphite (SFG6) which was produced by heat treatment at about 3000{degrees}C. Carbon fibers that were first impregnated with LiOH solution followed by reaction with CO{sub 2} to form Li{sub 2}CO{sub 3} tended to show lower irreversible capacity losses.

    Catalytic fast pyrolysis is a promising technique for conversion of biomass into hydrocarbons for use as transportation fuels. For over 30 years this process has been studied and it has been demonstrated that oils can be produced with high concentrations of hydrocarbons and low levels of oxygen. However, the yields from this type of conversion are typically low and the catalysts, which are often zeolites, are quickly deactivated through coking. In addition, the hydrocarbons produced are primarily aromatic molecules (benzene, toluene, xylene) that not desirable for petroleum refineries and are not well suited for diesel or jet engines. The goals of our research are to develop new multifunction catalysts for the production of gasoline, diesel and jet fuel range molecules and to improve process conditions for higher yields and low coking rates. We are investigating filtration and the use of hydrogen donor molecules to improve catalyst performance.

    1980-02-01

    An experimental study of the coking rate in 5 cm ID fluidized-bed reactors, in which the feed gas composition, the total pressure, and the fresh feed/recycle gas ratios were varied over wide ranges, showed a strong correlation between the carbon deposition rate and the ratio of carbon monoxide partial pressure to the square of the hydrogen partial pressure at the reactor inlet over a wide gas-composition range. At a given fresh gas composition, the combination rate varied inversely with the total pressure of the system. Coking decreased as the moles of CO + CO/sub 2/ converted to hydrocarbon increased. A Fischer-Tropsch reaction scheme is proposed and is used to derive a rate expression for catalyst carbonation that was approximately confirmed.

    Aluminous ore such as bauxite containing alumina is blended with coke or other suitable form of carbon and reacted with sulfur gas at an elevated temperature. For handling, the ore and coke can be extruded into conveniently sized pellets. The reaction with sulfur gas produces molten aluminum sulfide which is separated from residual solid reactants and impurities. The aluminum sulfide is further increased in temperature to cause its decomposition or sublimation, yielding aluminum subsulfide liquid (AlS) and sulfur gas that is recycled. The aluminum monosulfide is then cooled to below its disproportionation temperature to again form molten aluminum sulfide and aluminum metal. A liquid-liquid or liquid-solid separation, depending on the separation temperature, provides product aluminum and aluminum sulfide for recycle to the disproportionation step.

  14. Study of deactivation and regeneration of catalysts used in the LC-fining of solvent refined coal

    Batch experiments as well as results from LC-Fining catalytic upgrading of coal extracts indicate deactivation of the Shell 324 Ni/Mo catalyst in the presence of solvent refined coal (SRC). At increased levels of SRC loading, deactivation increases. The chief cause of catalyst deactivation appears to be coking. The Shell 324 catalyst can be substantially regenerated after the upgrading reaction by medium temperature ashing followed by presulfiding.

  15. Application of a catalyst deactivation model for hydrotreating solvent refined coal feedstocks

    SciTech Connect (OSTI)

    Nalitham, R.V.

    1983-10-01

    A simple kinetic model, including a first-order catalyst deactivation rate, is applied to upgrading of coal-derived feedstocks prepared from two solvent refined coal fractions. A catalyst deactivation mechanism is proposed which involves the adsorption and surface reaction of coke precursors on catalytic active sites. The effect of feedstock composition, temperature and pressure on kinetic parameters, and in particular the catalyst deactivation rate, is determined.

    Risch, Alan P. (New Fairfield, CT); Rabo, Jule A. (Armonk, NY)

    1983-01-01

    Carbon monoxide-containing gas streams are passed over a catalyst to deposit a surface layer of active surface carbon thereon essentially without the formation of inactive coke. The active carbon is thereafter reacted with steam or hydrogen to form methane. Enhanced catalyst stability for long term, cyclic operation is obtained by the incorporation of an alkali or alkaline earth dopant in a silica binding agent added to the catalyst-support additive composition.

    This report summarizes the accomplishments toward project goals during the first six months of the third year of the project to assess the properties and performance of coal based products. These products are in the gasoline, diesel and fuel oil range and result from coal based jet fuel production from an Air Force funded program. Specific areas of progress include generation of coal based material that has been fractionated into the desired refinery cuts, acquisition and installation of a research gasoline engine, and modification of diesel engines for use in evaluating diesel produced in the project. Characterization of the gasoline fuel indicates a dominance of single ring alkylcycloalkanes that have a low octane rating; however, blends containing these compounds do not have a negative effect upon gasoline when blended in refinery gasoline streams. Characterization of the diesel fuel indicates a dominance of 3-ring aromatics that have a low cetane value; however, these compounds do not have a negative effect upon diesel when blended in refinery diesel streams. The desulfurization of sulfur containing components of coal and petroleum is being studied so that effective conversion of blended coal and petroleum streams can be efficiently converted to useful refinery products. Equipment is now in place to begin fuel oil evaluations to assess the quality of coal based fuel oil. Combustion and characterization of fuel oil indicates that the fuel is somewhere in between a No. 4 and a No. 6 fuel oil. Emission testing indicates the fuel burns similarly to these two fuels, but trace metals for the coal-based material are different than petroleum-based fuel oils. Co-coking studies using cleaned coal are highly reproducible in the pilot-scale delayed coker. Evaluation of the coke by Alcoa, Inc. indicated that while the coke produced is of very good quality, the metals content of the carbon is still high in iron and silica. Coke is being evaluated for other possible uses. Methods to reduce metal content are being evaluated.

    New study determines the effect of catalyst structure on product yields and coking during vapor phase upgrading of biomass pyrolysis products. Converting biomass, an abun- dant and renewable resource, into liquid transportation fuels has attracted significant atten- tion because of depleting fossil fuel reserves and associated environmental concerns. In the quest for sustainable and eco-friendly fuel alternatives, much research is focusing on improving the properties of bio-oil. Scientists at

    The burden consists of 50% high basicity sinter and 50% home made olivine pellets. Two coke oven plants produce the required coke, about 340 kg/t (680 lb/NT). The average pulverized coal injection rate is 150 kg/t (300 lb/NT). To anticipate the aging coke oven plant No. 2 the coal injection capacity will e increased by 50% in 1996, by the installation of a third coal grinding line. In the Netherlands environmental issues have a high impact on further developments. In particular the environmental regulations require a significant decrease of dust, SO{sub 2} and dioxins emitted by the sinter plant. The appropriate measures must be concluded in the second part of this decade. To avoid costly conventional solutions Hoogovens has been testing since April, 1994 the Emission Optimized Sintering (EOS). In case of failure of EOS, the situation of a (partially) closed sinter plant was tested. Purchased pellets replaced sinter, leading to a 100% pellet and an 80% pellet/20% sinter trial. The trials were executed in the first half of 1994 at blast furnace No. 6, equipped with a PW-bell less top. Results are described.

    This study reports synthesis, characterization, and catalytic activity of the nano-size hierarchical HZSM-5 zeolite with high mesoporosity produced via a solvent evaporation procedure. Further, this study compares hierarchical zeolites with conventional HZSM-5 zeolite with similar Si/Al ratios for the ethanol-to-hydrocarbon conversion process. The catalytic performance of the hierarchical and conventional zeolites was evaluated using a fixed-bed reactor at 360 C, 300 psig, and a weight hourly space velocity of 7.9 h-1. For the low Si/Al ratio zeolite (~40), the catalytic life-time for the hierarchical HZSM-5 was approximately 2 times greater than the conventional HZSM-5 despite its coking amount deposited 1.6 times higher than conventional HZSM-5. For the high Si/Al ratio zeolite (~140), the catalytic life-time for the hierarchical zeolite was approximately 5 times greater than the conventional zeolite and the amount of coking deposited was 2.1 times higher. Correlation was observed between catalyst life time, porosity, and the crystal size of the zeolite. The nano-size hierarchical HZSM-5 zeolites containing mesoporosity demonstrated improved catalyst life-time compared to the conventional catalyst due to faster removal of products, shorter diffusion path length, and the migration of the coke deposits to the external surface from the pore structure.

    The Nation's continued reliance on liquid fossil fuels and decreasing reserves of light oils gives increased impetus to improving the recovery of heavy oil. Thermal enhanced oil recovery EOR techniques, such as steam injection, have generally been the most effective for increasing heavy oil production. However, conventional steam generation consumes a large fraction of the produced oil. The substitution of alternate (solid) fuels would release much of this consumed oil to market. This two-part report focuses on two solid fuels available in California, the site of most thermal EOR - petroleum coke and lignite. Phase I, entitled Economic Analysis, shows detailed cost comparisons between the two candidate fuels and also with Western coal. The analysis includes fuels characterizations, process designs for several combustion systems, and a thorough evaluation of the technical and economic uncertainties. In Phase II, many technical parameters of petroleum coke combustion were measured in a pilot-plant fluidized bed. The results of the study showed that petroleum coke combustion for EOR is feasible and cost effective in a fluidized bed combustor.

    The effects of blending polyethylene (PE), polystyrene (PS), poly(ethyleneterephthalate) (PET), a flexible polyurethane (FPU), and a car shredded fluff waste (CSF) on fluidity development of a bituminous coal during carbonization have been studied by means of high-torque, small-amplitude controlled-strain rheometry and in situ high-temperature {sup 1}H NMR spectroscopy. The most detrimental effects were caused by PET and PS, which completely destroyed the fluidity of the coal. The CSF had a deleterious effect on coal fluidity similar to that of PET, although the deleterious effect on the viscoelastic properties of the coal were less pronounced than those of PET and PS. On the contrary, the addition of 10 wt % PE caused a slight reduction in the concentration of fluid hydrogen and an increase in the minimum complex viscosity, and the addition of 10 wt % FPU reduced the concentration of fluid hydrogen without changing the viscoelastic properties of the coal. Although these results suggest that these two plastics could potentially be used as additives in coking blends without compromising coke porosity, it was found that the semicoke strengths were reduced by adding 2 wt % FPU and 5 wt % PE. Therefore, it is unlikely that more than 2 wt % of a plastic waste could be added to a coal blend without deterioration in coke quality. 35 refs., 11 figs., 3 tabs.

    About 37-50% (w/w) of the heptane asphaltenes from unpyrolyzed residua dissolve in cyclohexane. As pyrolysis progresses, this number decrease to below 15% as coke and toluene insoluble pre-coke materials appear. This solubility measurement can be used after coke begins to form, unlike the flocculation titration, which cannot be applied to multi-phase systems. Currently, the procedure for the isolation of heptane asphaltenes and the determination of the amount of asphaltenes soluble in cyclohexane spans three days. A more rapid method to measure asphaltene solubility was explored using a novel on-column asphaltene precipitation and re-dissolution technique. This was automated using high performance liquid chromatography (HPLC) equipment with a step gradient sequence using the solvents: heptane, cyclohexane, toluene:methanol (98:2). Results for four series of original and pyrolyzed residua were compared with data from the gravimetric method. The measurement time was reduced from three days to forty minutes. The separation was expanded further with the use of four solvents: heptane, cyclohexane, toluene, and cyclohexanone or methylene chloride. This provides a fourth peak which represents the most polar components, in the oil.

    This NETL sponsored effort seeks to develop continuous technologies for the production of carbon products, which may be thought of as the heavier products currently produced from refining of crude petroleum and coal tars obtained from metallurgical grade coke ovens. This effort took binder grade pitch, produced from liquefaction of West Virginia bituminous grade coal, all the way to commercial demonstration in a state of the art arc furnace. Other products, such as crude oil, anode grade coke and metallurgical grade coke were demonstrated successfully at the bench scale. The technology developed herein diverged from the previous state of the art in direct liquefaction (also referred to as the Bergius process), in two major respects. First, direct liquefaction was accomplished with less than a percent of hydrogen per unit mass of product, or about 3 pound per barrel or less. By contrast, other variants of the Bergius process require the use of 15 pounds or more of hydrogen per barrel, resulting in an inherent materials cost. Second, the conventional Bergius process requires high pressure, in the range of 1500 psig to 3000 psig. The WVU process variant has been carried out at pressures below 400 psig, a significant difference. Thanks mainly to DOE sponsorship, the WVU process has been licensed to a Canadian Company, Quantex Energy Inc, with a commercial demonstration unit plant scheduled to be erected in 2011.

    The goal of this series of design and estimating efforts was to start from the as-built design and actual operating data from the DOE sponsored Wabash River Coal Gasification Repowering Project and to develop optimized designs for several coal and petroleum coke IGCC power and coproduction projects. First, the team developed a design for a grass-roots plant equivalent to the Wabash River Coal Gasification Repowering Project to provide a starting point and a detailed mid-year 2000 cost estimate based on the actual as-built plant design and subsequent modifications (Subtask 1.1). This unoptimized plant has a thermal efficiency of 38.3% (HHV) and a mid-year 2000 EPC cost of 1,681 $/kW. This design was enlarged and modified to become a Petroleum Coke IGCC Coproduction Plant (Subtask 1.2) that produces hydrogen, industrial grade steam, and fuel gas for an adjacent Gulf Coast petroleum refinery in addition to export power. A structured Value Improving Practices (VIP) approach was applied to reduce costs and improve performance. The base case (Subtask 1.3) Optimized Petroleum Coke IGCC Coproduction Plant increased the power output by 16% and reduced the plant cost by 23%. The study looked at several options for gasifier sparing to enhance availability. Subtask 1.9 produced a detailed report on this availability analyses study. The Subtask 1.3 Next Plant, which retains the preferred spare gasification train approach, only reduced the cost by about 21%, but it has the highest availability (94.6%) and produces power at 30 $/MW-hr (at a 12% ROI). Thus, such a coke-fueled IGCC coproduction plant could fill a near term niche market. In all cases, the emissions performance of these plants is superior to the Wabash River project. Subtasks 1.5A and B developed designs for single-train coal and coke-fueled power plants. This side-by-side comparison of these plants, which contain the Subtask 1.3 VIP enhancements, showed their similarity both in design and cost (1,318 $/kW for the coal plant and 1,260 $/kW for the coke plant). Therefore, in the near term, a coke IGCC power plant could penetrate the market and provide a foundation for future coal-fueled facilities. Subtask 1.6 generated a design, cost estimate and economics for a multiple train coal-fueled IGCC powerplant, also based on the Subtaks 1.3 cases. The Subtask 1.6 four gasification train plant has a thermal efficiency of 40.6% (HHV) and cost 1,066 $/kW. The single-train advanced Subtask 1.4 plant, which uses an advanced ''G/H-class'' combustion turbine, can have a thermal efficiency of 45.4% (HHV) and a plant cost of 1,096 $/kW. Multi-train plants will further reduce the cost. Again, all these plants have superior emissions performance. Subtask 1.7 developed an optimized design for a coal to hydrogen plant. At current natural gas prices, this facility is not competitive with hydrogen produced from natural gas. The preferred scenario is to coproduce hydrogen in a plant similar to Subtask 1.3, as described above. Subtask 1.8 evaluated the potential merits of warm gas cleanup technology. This study showed that selective catalytic oxidation of hydrogen sulfide (SCOHS) is promising. As gasification technology matures, SCOHS and other improvements identified in this study will lead to further cost reductions and efficiency improvements.

  16. Use of High Temperature Electrochemical Cells for Co-Generation of Chemicals and Electricity

    In this project, two key issues were addressed to show the feasibility of electrochemical partial oxidation (EPOx) in a SOFC. First, it was demonstrated that SOFCs can reliably operate directly with natural gas. These results are relevant to both direct-natural-gas SOFCs, where the aim is solely electrical power generation, and to EPOx. Second, it must be shown that SOFCs can work effectively as partial oxidation reactors, i.e, that they can provide high conversion efficiency of natural gas to syngas. The results of this study in both these areas look extremely promising. The main results are summarized briefly: (1) Stability and coke-free direct-methane SOFC operation is promoted by the addition of a thin porous inert barrier layer to the anode and the addition of small amounts of CO{sub 2} or air to the fuel stream; (2) Modeling results readily explained these improvements by a change in the gas composition at the Ni-YSZ anode to a non-coking condition; (3) The operation range for coke-free operation is greatly increased by using a cell geometry with a thin Ni-YSZ anode active layer on an inert porous ceramic support, i.e., (Sr,La)TiO{sub 3} or partially-stabilized zirconia (in segmented-in-series arrays); (4) Ethane and propane components in natural gas greatly increase coking both on the SOFC anode and on gas-feed tubes, but this can be mitigated by preferentially oxidizing these components prior to introduction into the fuel cell, the addition of a small amount of air to the fuel, and/or the use of ceramic-supported SOFC; (5) While a minimum SOFC current density was generally required to prevent coking, current interruptions of up to 8 minutes yielded only slight anode coking that caused no permanent damage and was completely reversible when the cell current was resumed; (6) Stable direct-methane SOFC operation was demonstrated under EPOx conditions in a 350 h test; (7) EPOx operation was demonstrated at 750 C that yielded 0.9 W/cm{sup 2} and a syngas production rate of 30 sccm/cm{sup 2}, and the reaction product composition was close to the equilibrium prediction during the early stages of cell testing; (8) The methane conversion to syngas continuously decreased during the first 100 h of cell testing, even though the cell electrical characteristics did not change, due to a steady decrease in the reforming activity of Ni-YSZ anodes; (9) The stability of methane conversion was substantially improved via the addition of a more stable reforming catalyst to the SOFC anode; (10) Modeling results indicated that a SOFC with anode barrier provides similar non-coking performance as an internal reforming SOFC, and provides a simpler approach with no need for a high-temperature exhaust-gas recycle pump; (11) Since there is little or no heat produced in the EPOx reaction, overall efficiency of the SOFC operated in this mode can, in theory, approach 100%; and (12) The combined value of the electricity and syngas produced allows the EPOx generator to be economically viable at a >2x higher cost/kW than a conventional SOFC.

    This report summarizes the accomplishments toward project goals during the no cost extension period of the third year of the project to assess the properties and performance of coal based products. These products are in the gasoline, diesel and fuel oil range and result from coal based jet fuel production from an Air Force funded program. Specific areas of progress include generation of coal based material that has been fractionated into the desired refinery cuts for a third round of testing, the use of a research gasoline engine to test coal-based gasoline, and modification of diesel engines for use in evaluating diesel produced in the project. At the pilot scale, the hydrotreating process was modified to separate the heavy components from the LCO and RCO fractions before hydrotreating in order to improve the performance of the catalysts in further processing. Hydrotreating and hydrogenation of the product has been completed, and due to removal of material before processing, yield of the jet fuel fraction has decreased relative to an increase in the gasoline fraction. Characterization of the gasoline fuel indicates a dominance of single ring alkylcycloalkanes that have a low octane rating; however, blends containing these compounds do not have a negative effect upon gasoline when blended in refinery gasoline streams. Characterization of the diesel fuel indicates a dominance of 3-ring aromatics that have a low cetane value; however, these compounds do not have a negative effect upon diesel when blended in refinery diesel streams. Both gasoline and diesel continue to be tested for combustion performance. The desulfurization of sulfur containing components of coal and petroleum is being studied so that effective conversion of blended coal and petroleum streams can be efficiently converted to useful refinery products. Activated carbons have proven useful to remove the heavy sulfur components, and unsupported Ni/Mo and Ni/Co catalysts have been very effective for hydrodesulfurization. Equipment is now in place to begin fuel oil evaluations to assess the quality of coal based fuel oil. Combustion and characterization of the latest fuel oil (the high temperature fraction of RCO from the latest modification) indicates that the fraction is heavier than a No. 6 fuel oil. Combustion efficiency on our research boiler is {approx}63% for the heavy RCO fraction, lower than the combustion performance for previous co-coking fuel oils and No. 6 fuel oil. Emission testing indicates that the coal derived material has more trace metals related to coal than petroleum, as seen in previous runs. An additional coal has been procured and is being processed for the next series of delayed co-coking runs. The co-coking of the runs with the new coal have begun, with the coke yield similar to previous runs, but the gas yield is lower and the liquid yield is higher. Characterization of the products continues. Work continues on characterization of liquids and solids from co-coking of hydrotreated decant oils; liquid yields include more saturated and hydro- aromatics, while the coke quality varies depending on the conditions used. Pitch material is being generated from the heavy fraction of co-coking.

  19. Final Technical Report - High-Performance, Oxide-Dispersion-Strengthened Tubes for Production of Ethylene adn Other Industrial Chemicals

    McKimpson, Marvin G.

    2006-04-06

    This project was undertaken by Michigan Technological University and Special Metals Corporation to develop creep-resistant, coking-resistant oxide-dispersion-strengthened (ODS) tubes for use in industrial-scale ethylene pyrolysis and steam methane reforming operations. Ethylene pyrolysis tubes are exposed to some of the most severe service conditions for metallic materials found anywhere in the chemical process industries, including elevated temperatures, oxidizing atmospheres and high carbon potentials. During service, hard deposits of carbon (coke) build up on the inner wall of the tube, reducing heat transfer and restricting the flow of the hydrocarbon feedstocks. About every 20 to 60 days, the reactor must be taken off-line and decoked by burning out the accumulated carbon. This decoking costs on the order of $9 million per year per ethylene plant, accelerates tube degradation, and requires that tubes be replaced about every 5 years. The technology developed under this program seeks to reduce the energy and economic cost of coking by creating novel bimetallic tubes offering a combination of improved coking resistance, creep resistance and fabricability not available in current single-alloy tubes. The inner core of this tube consists of Incoloy(R) MA956, a commercial ferritic Fe-Cr-Al alloy offering a 50% reduction in coke buildup combined with improved carburization resistance. The outer sheath consists of a new material - oxide dispersion strengthened (ODS) Alloy 803(R) developed under the program. This new alloy retains the good fireside environmental resistance of Alloy 803, a commercial wrought alloy currently used for ethylene production, and provides an austenitic casing to alleviate the inherently-limited fabricability of the ferritic Incoloy(R) MA956 core. To provide mechanical compatibility between the two alloys and maximize creep resistance of the bimetallic tube, both the inner Incoloy(R) MA956 and the outer ODS Alloy 803 are oxide dispersion strengthened materials produced using mechanical alloying technology. To minimize cost, the bimetallic tube is produced by direct powder co-extrusion. This technology has potential for domestic energy savings of up to 4.1 trillion BTU/year (4.3 x 1015J/year) and a reduction of 370,000 tons (340,000 tonnes) of CO2 emissions in short-residence-time ethylene furnaces. This represents an energy savings and CO2 emissions reduction of about 3.3%. If the technology is also applied to other types of ethylene pyrolysis furnaces, total energy savings and CO2 emissions reductions could increase by up to five times. The work involved: Developing powder and consolidation processing protocols to produce an oxide-dispersion strengthened variant of Alloy 803 exhibiting creep strength comparable to Incoloy? Alloy MA956, Developing a direct powder co-extrusion protocol for fabricating co-extruded bimetallic Incoloy? Alloy MA956 / ODS Alloy 803 tubes, Characterizing the properties of the ODS Alloy 803 material, the welding characteristics of the bimetallic tubes, and the coking characteristics of the Incoloy? MA956 alloy, and Documenting the potential energy savings and user requirements for these bimetallic pyrolysis furnace tubes. The project demonstrated that oxide dispersion strengthened Alloy 803 can be produced successfully using conventional mechanical alloying technology. The oxide dispersion strengthened bimetallic radiant coil technology explored under this program has significant potential for energy savings and productivity improvements for domestic ethylene producers. In today's competitive market, however, domestic furnace manufacturers and ethylene producers appear reluctant to pay any cost premium for higher-performance coil materials offering either higher temperature capabilities or longer service life. Interest in oxide dispersion strengthened radiant coils is likely to increase if furnace and ethylene producers begin to focus more on increasing tube wall temperatures to improve productivity.

    The objective of this report is to review and update the 1988 report by J. E. Sinor Consultants Inc., ``Industrial Market Assessment of the Products of Mild Gasification, and to more fully present market opportunities for two char-based products from the mild gasification process (MGP): Formcoke for the iron and steel industry, and activated carbon for wastewater cleanup and flue gas scrubbing. Please refer to the original report for additional details. In the past, coal conversion projects have and liquids produced, and the value of the residual char was limited to its fuel value. Some projects had limited success until gas and oil competition overwhelmed them. The strategy adopted for this assessment is to seek first a premium value for the char in a market that has advantages over gas and oil, and then to find the highest values possible for gases, liquids, and tars, either on-site or sold into existing markets. During the intervening years since the 1988 report, there have been many changes in the national economy, industrial production, international competition, and environmental regulations. The Clean Air Act Amendments of 1990 (CAAA) will have a large impact on industry. There is considerable uncertainty about how the Act will be implemented, but it specifically addresses coke-oven batteries. This may encourage industry to consider formcoke produced via mild gasification as a low-pollution substitute for conventional coke. The chemistry and technology of coke making steel were reviewed in the 1988 market assessment and will not be repeated here. The CAAA require additional pollution control measures for most industrial facilities, but this creates new opportunities for the mild gasification process.

    An automated separation technique was developed that provides a new approach to measuring the distribution profiles of the most polar, or asphaltenic components of an oil, using a continuous flow system to precipitate and re-dissolve asphaltenes from the oil. Methods of analysis based on this new technique were explored. One method based on the new technique involves precipitation of a portion of residua sample in heptane on a polytetrafluoroethylene-packed (PTFE) column. The precipitated material is re-dissolved in three steps using solvents of increasing polarity: cyclohexane, toluene, and methylene chloride. The amount of asphaltenes that dissolve in cyclohexane is a useful diagnostic of the thermal history of oil, and its proximity to coke formation. For example, about 40 % (w/w) of the heptane asphaltenes from unpyrolyzed residua dissolves in cyclohexane. As pyrolysis progresses, this number decrease to below 15% as coke and toluene insoluble pre-coke materials appear. Currently, the procedure for the isolation of heptane asphaltenes and the determination of the amount of asphaltenes soluble in cyclohexane spans three days. The automated procedure takes one hour. Another method uses a single solvent, methylene chloride, to re-dissolve the material that precipitates on heptane on the PTFE-packed column. The area of this second peak can be used to calculate a value which correlates with gravimetric asphaltene content. Currently the gravimetric procedure to determine asphaltenes takes about 24 hours. The automated procedure takes 30 minutes. Results for four series of original and pyrolyzed residua were compared with data from the gravimetric methods. Methods based on the new on-column precipitation and re-dissolution technique provide significantly more detail about the polar constituent's oils than the gravimetric determination of asphaltenes.

    Current candidate graphite grades for the core structures of NGNP include grades NBG-17, NBG-18, PCEA and IG-430. Both NBG-17 and NBG-18 are manufactured using pitch coke, and are vibrationally molded. These medium grain products are produced by SGL Carbon SAS (France). Tayo Tanso (Japan) produces IG-430 which is a petroleum coke, isostatically molded, nuclear grade graphite. And PCEA is a medium grain, extruded graphite produced by UCAR Carbon Co. (USA) from petroleum coke. An experimental program has been initiated to develop physical and mechanical properties data for these current candidate graphites. The results will be judged against the requirements for nuclear grade graphites set forth in ASTM standard D 7219-05 "Standard Specification for Isotropic and Near-isotropic Nuclear Graphites". Physical properties data including thermal conductivity and coefficient of thermal expansion, and mechanical properties data including tensile, compressive and flexural strengths will be obtained using the established test methods covered in D-7219 and ASTM C 781-02 "Standard Practice for Testing Graphite and Boronated Graphite Components for High-Temperature Gas-Cooled Nuclear Reactors". Various factors known to effect the properties of graphites will be investigated. These include specimen size, spatial location within a graphite billet, specimen orientation (ag and wg) within a billet, and billet-to-billet variations. The current status of the materials characterization program is reported herein. To date billets of the four graphite grades have been procured, and detailed cut up plans for obtaining the various specimens have been prepared. Particular attention has been given to the traceability of each specimen to its spatial location and orientation within a billet.

    Bimetallic tubes are used for very specific applications where one of the two metals provides strength and the other provides specific properties such as aqueous corrosion and carburization, coking resistance, and special electrical and thermal properties. Bimetallic tubes have application in pulp and paper industry for heat-recovery boilers, in the chemical industry for ethylene production, and in the petrochemical industry for deep oil well explorations. Although bimetallic tubes have major applications in energy-intensive industry, they often are not used because of their cost and manufacturing sources in the United States. This project was intended to address both of these issues.

    On the occasion of the 1995 AIME conference the new PROven (Pressure Regulated Oven) process to control the pressure in coke ovens individually was introduced. This process was made feasible with a new collecting main valve, termed FixCup, with the aid of this valve a variable flow resistance to the raw gas discharge can be realized using a water immersion system. However, just the application of the FixCup system alone--without any pressure regulation--is very advantageous and cost saving. Thyssen has equipped 30 ovens with the new valve. The special constructive features as well as the operational experience using the FixCup valve are treated.

    For a very long time and regardless of all shortcomings associated with it, the manual measurement of the heating flue temperature has been the only method of monitoring the temperature prevailing in a coke oven battery and discovering weak points in the heating system. In the course of the last few years a number of automated temperature measuring systems have been developed that are intended to replace or supplement the manual heating flue measurement system. These measuring systems and their advantages/disadvantages are briefly described in this paper. Additionally, operational experience gathered with the oven chamber wall temperature measuring system is discussed in detail.

    The regulations for pollution control are being strengthened more year by year. Therefore, waste materials containing iron oxides are being increasingly used in the sinter plant. As a result, waste materials recycling in the sintering process not only reduces costs by eliminating waste disposal costs and utilizing Fe bearing by-products to replace iron ores and flux materials, but gives fuel rate benefits to the sintering process through heat of oxidizing of Fe bearing materials and combustion of coke fines carried with Fe Bearing by-products.

    When the rebuilt Coke Plant started operations in November of 1992, it featured a completely new closed circuit secondary cooler, ammonia scrubbing, ammonia distillation, and ammonia destruction plants. This is the second plant of this type to be built in North America. To remove the ammonia from the gas, it is scrubbed with three liquids: Approximately 185 gallons/minute of cooled stripped liquor from the ammonia stills; Light oil plant condensate; and Optionally, excess flushing liquor. These scrubbers typically reduce ammonia content in the gas from 270 Grains/100 standard cubic feet to 0.2 Grains/100 standard cubic feet.

    Pilot and/or laboratory studies were conducted in order to find methods for reducing the SOx emission in the Claus tail gas of the cokes unit. The TGT process which is based on the complete hydrogenation of the sulfur-containing compounds (SO{sub 2}, S) into H{sub 2}S and returning to the COG main line can reduce the SOx emission to zero. In case the return to the COG main is impossible, the SPOR process (Sulfur removal based on Partial Oxidation and Reduction) can be successfully applied to reduce the SOx emission.

  11. PHASE II CALDERON PROCESS TO PRODUCE DIRECT REDUCED IRON RESEARCH AND DEVELOPMENT PROJECT

    The commercialization path of the Calderon technology for making a feedstock for steelmaking with assistance from DOE initially focused on making coke and work was done which proved that the Calderon technology is capable of making good coke for hard driving blast furnaces. U.S. Steel which participated in such demonstration felt that the Calderon technology would be more meaningful in lowering the costs of making steel by adapting it to the making of iron--thus obviating the need for coke. U.S. Steel and Calderon teamed up to jointly work together to demonstrate that the Calderon technology will produce in a closed system iron units from iron concentrate (ore) and coal competitively by eliminating pelletizing, sintering, coking and blast furnace operation. If such process steps could be eliminated, a huge reduction in polluting emissions and greenhouse gases (including CO{sub 2}) relating to steelmaking would ensue. Such reduction will restructure the steel industry away from the very energy-intensive steelmaking steps currently practiced and drastically reduce costs of making steel. The development of a technology to lower U.S. steelmaking costs and become globally competitive is a priority of major importance. Therefore, the development work which Calderon is conducting presently under this Agreement with the U.S. Department of Energy becomes more crucial than ever. During the 3rd quarter of 2005 which the present report covers, virtually all the effort to advance the Calderon technology to make iron units was concentrated towards forming a team with a steelmaker who needs both iron units in the form of hot metal and a substitute for natural gas (SNG), both being major contributors to higher costs in steelmaking. Calderon felt that a very good candidate would be Steel Dynamics (SDI) by virtue that it operates a rotary hearth facility in Butler, Indiana that uses large amounts of natural gas to reduce briquettes made from ore and coal that they subsequently melt in a submerged arc furnace that is a large consumer of electric power. This facility is operated as a division of SDI under the name of Iron Dynamics (IDI). It is no secret that IDI has had and still has a great number of operational problems, including high cost for natural gas.

    After six months of operation of the pilot plant, the viability of in-bath smelting combined with a high level of post combustion has been demonstrated, and the opportunity exists for an early commercialization of the direct ironmaking part of the process while we continue to research direct steelmaking. The program should be of equal interest to integrated and electric furnace producers. Smelting of ore provides virgin iron units. Additionally, the process has the flexibility of melting scrap and varying the ore-to-scrap ratio over wide ranges. This process does not require coke, thus eliminating the cokemaking operation, a major source of environmental concern.

    An improved downhole steam injector has an angled water orifice to swirl the water through the device for improved heat transfer before it is converted to steam. The injector also has a sloped diameter reduction in the steam chamber to throw water that collects along the side of the chamber during slant drilling into the flame for conversion to steam. In addition, the output of the flame chamber is beveled to reduce hot spots and increase efficiency, and the fuel-oxidant inputs are arranged to minimize coking.

    Solids removal in coprocessing by filtration rather than vacuum distillation offers possibilities of altering process products and their yields (for example, a clean ash free pitch or coke could be produced). Samples of heavy ends from the CANMET process have been tested in a series of small-scale laboratory filtration tests, in which rates were measured and specific cake resistivities subsequently calculated. The effects of feed pre-concentration, filter pressure and addition of carbon filter aid air reported. The results indicate that the removal of solids from this feedstock by filtration is technically and economically feasible.
