Book excerpt: Southern Illinois University at Carbondale will develop and demonstrate several technologies for the handling and transport of dry coal combustion residues and for the underground placement in abandoned coal mines and assess associated environmental impacts. Although parts of the Residue Characterization portion of the program were delayed because residue samples were not obtained, other parts of the program are proceeding on schedule. The delays in obtaining residue samples were primarily caused by adverse weather conditions, the shut-down of one unit at the City Water, Light, and Power Company Plant for routing maintenance and problems due to conflicting schedules of utility and program personnel. However, by the end of the quarter most residue samples had been obtained, and the residue characterization studies were under way. Progress is described for five studies: environmental assessment and geotechnical stability and subsidence impacts; residue characterization; physico-chemical characterization of residues; identification and assessment of handling/transportation systems for FGD residues; and residue handling and transport.

Book excerpt: The ''Management of Dry Flue Gas Desulfurization By-Products in Underground Mines'' program is one of the largest programs ever undertaken by the Mining Engineering Department of Southern Illinois university, both in terms of complexity and in terms of funding. Total funding over the expected four-year extent of the program, including both Department of Energy, matching Southern Illinois University funds, and contributed funds, this program exceeds three million dollars. The number of cooperating organizations adds to the management complexity of the program. It was believed, therefore, that sound management plan and management base is essential for the efficient and effective conduct of the program. This first quarter period (i.e., October 1--December 31, 1993) was developed to establishing the management base, developing a sound management plan, developing a test plan, and developing sound fiscal management and control. Actual technical operations, such as residue sample acquisition, residue analyses, groundwater sample acquisition and analyses, and material handling studies will get underway early in the next quarter (i.e., January 1--March 31, 1994). Some early results of residue analyses and groundwater analyses should be available by the end of the second quarter. These results will be reported in the next Technical Progress Report.

Book excerpt: On September 30, 1993, the U.S. Department of Energy, Morgantown Energy Technology Center and Southern Illinois University at Carbondale (SIUC) entered into a cooperative research agreement entitled {open_quotes}Management of Dry Flue Gas Desulfurization By-Products in Underground Mines{close_quotes} (DE-FC21-93MC 30252). Under the agreement Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. Previous quarterly Technical Progress Reports have set forth the specific objectives of the program, as well as the management plan and the test plan for the overall program, and a discussion of these will not be repeated here. Rather, this report, will set forth the technical progress made during the period January 1 through March 31, 1995. The demonstration of the SEEC, Inc. technology for the transporting of coal combustion residues was completed with the unloading and final disposition of the three Collapsible Intermodal Containers (CIC). The loading and transport by rail of the three CIC's was quire successful; however some difficulties were encountered in the unloading of the containers. A full topical report on the entire SEEC demonstration is being prepared. As a result of the demonstration some modifications of the SEEC concept may be undertaken. Also during the quarter the location of the injection wells at the Peabody No. 10 mine demonstration site were selected. Peabody Coal Company has developed the specifications for the wells and sought bids for the actual drilling. It is expected that the wells will be drilled early in May.

Under the agreement Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. Previous quarterly Technical Progress Reports have set forth the specific objectives of the program, and a discussion of these is not repeated here. Rather, this report discusses the technical progress made during the period April 1 - June 30, 1995. A final topical report on the SEEC, Inc. demonstration of its technology for the transporting of coal combustion residues was completed during the quarter, although final printing of the report was accomplished early in July, 1995. The SEEC technology involves the use of Collapsible Intermodal Containers (CIC's) developed by SEEC, and the transportation of such containers - filled with fly ash or other coal combustion residues - on rail coal cars or other transportation means. Copies of the final topical report, entitled {open_quotes}The Development and Testing of Collapsible Intermodal Containers for the Handling and Transport of Coal Combustion Residues{close_quotes} were furnished to the Morgantown Energy Technology Center. The Rapid Aging Test colums were placed in operation during the quarter. This test is to determine the long-term reaction of both the pneumatic and hydraulic mixtures to brine as a leaching material, and simulates the conditions that will be encountered in the actual underground placement of the coal combustion residues mixtures. The tests will continue for about one year.

This book was released on 1998 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report represents the Final Technical Progress Report for Phase II of the overall program for a cooperative research agreement between the U.S. Department of Energy - MORGANTOWN Energy Technology Center (DOE-METC) and Southern Illinois University at Carbondale (SIUC). Under the agreement, SIUC will develop and demonstrate technologies for the handling, transport, and placement in abandoned underground coal mines of dry flue gas desulfurization by-products, such as fly ash, scrubber sludge, fluidized bed combustion by-products, and will assess the environmental impact of such underground placement. The overall program is divided into three (3) phases. Phase II of the program is primarily concerned with developing and testing the hardware for the actual underground placement demonstrations. Two technologies have been identified and hardware procured for full-scale demonstrations: (1) hydraulic placement, where coal combustion by-products (CCBs) will be placed underground as a past-like mixture containing about 70 to 75 percent solids; and (2) pneumatic placement, where CCBs will be placed underground as a relatively dry material using compressed air. 42 refs., 36 figs., 36 tabs.

This book was released on 1998 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The DESEVAL-TRANS program is developed for the purpose of helping the engineer to design and economically evaluate coal combustion byproduct transportation systems that will operate between the power plant and the disposal site. The objective of the research project was to explore the technical, environmental and economic feasibility of disposing coal combustion byproducts in underground mines in Illinois. The DESEVAL-TRANS (short for Design and Evaluation of Transportation Systems) was developed in the Materials Handling and Systems Economics branch of the overall project. Four types of coal combustion byproducts were targeted for transportation and handling: Conventional fly ash; Scrubber sludge; Fluidized Bed Combustion (FBC) fly ash; and Spent-bed ash. Several transportation and handling systems that could handle these byproducts were examined. These technologies were classified under three general categories: Truck; Rail; and Container. The purpose of design models is to determine the proper number of transport units, silo capacity, loading and unloading rates, underground placement capacity, number of shifts, etc., for a given case, defined by a distance-tonnage combination. The cost computation models were developed for the determination of the operating and capital costs. An economic evaluation model, which is common to all categories, was also developed to establish the cost-per-ton of byproduct transported.

This book was released on 1997 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was to develop and demonstrate two technologies for the placement of coal combustion by-products in abandoned underground coal mines, and to assess the environmental impact of these technologies for the management of CCB materials. The two technologies for the underground placement that were to be developed and demonstrated are: (1) pneumatic placement using virtually dry CCB products, and (2) hydraulic placement using a paste mixture of CCB products with about 70% solids. The period covered by this report is the second quarter of Phase 3 of the overall program. During this period over 8,000 tons of CCB mixtures was injected using the hydraulic paste technology. This amount of material virtually filled the underground opening around the injection well, and was deemed sufficient to demonstrate fully the hydraulic injection technology. By the end of this quarter about 2,000 tons of fly ash had been placed underground using the pneumatic placement technology. While the rate of injection of about 50 tons per hour met design criteria, problems were experienced in the delivery of fly ash to the pneumatic demonstration site. The source of the fly ash, the Archer Daniels Midland Company power plant at Decatur, Illinois is some distance from the demonstration site, and often sufficient tanker trucks are not available to haul enough fly ash to fully load the injection equipment. Further, on some occasions fly ash from the plant was not available. The injection well was plugged three times during the demonstration. This typically occurred due to cementation of the FBC ash in contact with water. After considerable deliberations and in consultation with the technical project officer, it was decided to stop further injection of CCB's underground using the developed pneumatic technology.
