Several underground coal gasification (UCG) experiments have been conducted in the Hanna No. 1 coal seam. During the fall, 1980, the Laramie Energy Technology Center performed a post-burn field study of the Hanna II, Phases 2 and 3 experiment at the Hanna UCG site. The field work consisted of high resolution seismic, drilling, coring, and geophysical logging. The Paleomagnetism Laboratory, Department of Geology, Colorado School of Mines, contributed to the post-burn study by doing remanent and rock magnetic measurement laboratory work on the core material. Funding was provided by the Laramie Energy Technology Center. The purpose of the study was to determine the nature of the remanent magnetism of the overburden Hanna Formation and changes in the remanence and magnetic mineralogy attending underground coal gasification experiments. With this information, further estimates of the thermal and chemical conditions reached during the conversion experiment could be made. The magnetization data, together with previous petrographic observations, suggest that magnetite is being formed in a reducing process at the expense of detrital ferromagnesian silicates and possible hematite and geothite in the overburden sediments. Thermal gradients immediately above the burn cavity are difficult to estimate; changes in magnetic properties of unaltered Hanna Formation overburden are …

An algorithm has been developed for the removal of autopower bias errors from conventional magnetotelluric (MT) data. Nonlinear equations involving autopowers as unknowns with crosspower coefficients are obtained by cross substitutions between the eight referenced impedance equations to eliminate the four impedances. Although exact solutions to the nonlinear equations can be computed, they are often sensitive to noise components in the crosspower coefficients, due to degeneracy of the equations as Z/sub xx/ and Z/sub yy/ approach zero or as the coherence between the magnetic field components H/sub x/ and H/sub y/ approaches unity. However, the ordinary coherence functions between various pairs of the horizontal field components provide additional information. This information is incorporated as constraints by developing a constrained iterative solution for the autopowers. The solution is outlined and its usefulness is explored with examples of its application to field data.

To keep the accelerator structures in proper tuned condition with variable applied RF power, the Cu-temperature of the structures should be kept constant. From the specifications in CN 102, we derive that a ..delta../PHI/ = +-10/sup 0/ per ten-foot structure would be permissible to stay within a ..delta..E/E of 0.5%. Further measurements should be performed to prove that all structures stay within this limit under the SLC operating conditions where the average RF power level will be in the order of ten times the average power used for the present test.

This burn test program was conducted during the period of August 1982 to February 1983 to demonstrate that Solvent Refined Coal (SRC) products can displace petroleum as a boiler fuel in oil- and gas-designed boilers. The test program was performed at the U.S. Department of Energy's Pittsburgh Energy Technology Center (PETC). Three forms of SRC (pulverized SRC, a solution of SRC dissolved in process-derived distillates, and a slurry of SRC and water) and No. 6 Fuel Oil were evaluated in the 700-hp (30 x 10/sup 6/ Btu/hour) watertube, oil-designed boiler facility at PETC. The test program was managed by the International Coal Refining Company (ICRC) and sponsored by the Department of Energy. Other organizations were involved as necessary to provide the expertise required to execute the test program. This final report represents an integrated overview of the test program conducted at PETC. More detailed information with preliminary data can be obtained from separate reports prepared by PETC, Southern Research Institute, Wheelabrator-Frye, Babcock and Wilcox, and Combustion Engineering. These are presented as Annex Volumes A-F. 25 references, 41 figures, 15 tables.

Solvent Refined Coal (SRC) combustion tests were conducted at the U.S. Department of Energy's Pittsburgh Energy Technology Center. Combustion and flue-gas treatment of three different physical forms of SRC, as well as a No. 6 fuel oil, were evaluated. The three SRC fuels were (1) pulverized SRC Fuel; (2) SRC Residual Fuel Oil; and (3) SRC/Water Slurry. The SRC Residual Fuel Oil was a solution of SRC Fuel dissolved in heated process solvent. Approximately 500 tons of pulverized SRC Fuel and 30,000 gallons of SRC Residual Fuel Oil were combusted in a 700 hp (30 x 130 x 10/sup 6/ Btu/hr fuel input) oil-designed watertube package boiler. Sixty four-hour ASME combustion tests with three different SRC fuels were successfully concluded. The principal parameters evaluated were excess air levels and combustion air preheat temperature levels. Extensive data were collected on flue-gas levels of O/sub 2/, CO/sub 2/, CO, unburned hydrocarbons, SO/sub x/, NO/sub x/, uncontrolled particulates, uncontrolled opacity and carbon content of the flue-gas particulates. Boiler and combustion efficiencies were measured. The particulates were characterized via mass loadings, impactors, in-situ resistivity measurements, ultra-fine sampling, optical large particle sampling, five-stage cyclone sampling and chemical analysis of various cut sizes. A three-field pilot …

The Aquatic Species Program (ASP) addresses the development of technologies that produce and utilize plant biomass species which naturally inhabit wetlands or submerged areas. Processes being developed through this program take advantage of the rapid growth rates, high yields, and extraordinary chemical compositions inherently associated with aquatic species. Emphasis is placed on salt tolerant species for cultivation on poorly utilized, low-value lands, where conventional agriculture is not economic. Candidate species are identified from: (1) microalgae-unicellular plants that are natural factories for converting sunlight into high quality oils; (2) macroalgae-large, chemically unique plants that can be easily fermented to methane gas or alcohols; and (3) emergents-plants that grow rooted in waterways and bogs, but are partially exposed above water. Within the next five years, the conditions and resources necessary for sustained systems operations are to be defined, design parameters examined, and experimental facilities developed. Succeeding years are planned to focus on resolving major technical hurdles in systems operations, integration, and component performance. This paper updates the technical progress in this program, describes several aspects of evolving systems concepts, and attempts to provide some perspectives based on potential economics. 16 references, 4 figures, 4 tables.

Abstract: "The Institute for Environmental Studies at Louisiana State University conducted research into the potential use of Louisiana salt domes for disposal of nuclear waste material. Topical reports generated in the 1981 and 1982 related to Vacherie and Rayburn's domes are compiled and presented, which address palynological studies, tiltmeter monitoring, precise releveling, saline springs, and surface hydrology. The latter two are basically a compilation of references related o these topics."

This report describes the third project undertaken by the Center for Transportation Research, Argonne National Laboratory (ANL), in a US Department of Energy program designed to develop and distribute compendiums of measures for saving transportation fuel. A matrix, or chart, of more than 60 fuel-saving measures was developed by ANL and refined with the assistance of trucking industry operators and researchers at an industry coordination meeting held in August 1982. The first two projects used similar meetings to refine matrices developed for the international maritime and US railroad industries. The consensus reached by those at the meeting was that the single most important element in a truck fuel-efficiency improvement program is the human element -- namely the development of strong motivation among truck drivers to save fuel. The role of the driver is crucial to the successful use of fuel-saving equipment and operating procedures. Identical conclusions were reached in the earlier maritime and rail meetings, thus providing a strong indication of the pervasive importance of the human element in energy-efficient transportation systems. The number and variety of changes made to the matrix are also delineated, including addition and deletion of various options and revisions of fuel-saving estimates, payback period estimates, …

Columbia River temperatures and flow rates are collected daily at Priest Rapids Dam and Vernita Bridge. These data are necessary for assessing trends or changes in river conditions downstream of Priest Rapids Dam. In order to analyze this data, Pacific Northwest Laboratory developed a computerized data base using existing US Geological Survey flow and temperature records at Priest Rapids Dam and Vernita Bridge. Daily-averaged temperature and daily flow information on the Columbia River just downstream of Priest Rapids Dam and upstream of river mile 380 were collected and stored in a data base. A newly developed computer model, COLSTAT (Columbia River Statistical Update), used the data base to statistically analyze temperature and flow conditions by computing the frequency of occurrence and duration of selected temperatures and flow rates for the Columbia River. Information regarding the data base is presented, as well as, a description of the COLSTAT model.

Sandia National Laboratories has been assisting the Department of Energy in the Uranium Mill Tailings Remedial Actions Program (UMTRAP) the purpose of which is to implement the provisions of Title I of Public Law 95-604, Uranium Mill Tailings Radiation Control Act of 1978.'' As part of this program, there was a need to evaluate the mineral concentration of the residual radioactive materials at some of the designated processing sites to determine whether mineral recovery would be practicable. Accordingly, Sandia contracted Mountain States Research and Development (MSRD), a division of Mountain States Mineral Enterprises, to drill, sample, and test tailings at 12 sites to evaluate the cost of and the revenue that could be derived from mineral recovery. UMTRAP related environmental and engineering sampling and support activities were performed in conjunction with the MSRD operations. This summary report presents a brief description of the various activities in the program and of the data and information obtained and summarizes the results. 8 refs., 9 tabs.

Solvent Refined Coal (SRC) is one of the viable replacement fuels for No. 6 fuel oil in industrial and utility boilers. The Department of Energy funded the International Coal Refining Company (ICRC) to develop and to demonstrate the use of SRC as a practical fuel. Phase II of the project was to burn the SRC fuels in a 700 hp package boiler and to collect emission data from which air pollution control devices could be specified. Wheelabrator-Frye, Inc., APC Division was contracted by ICRC to supply and operate a pilot electrostatic precipitator (ESP). Mass emission testing was performed by WFI Sciences. Particle size tests, particle resistivity, SO/sub x/ measurements, and particulate counting tests were conducted by Southern Research Institute (SoRI). This report is a source document covering the ESP operating data and mass emission data. The data obtained by SoRI is used by SoRI in their computer model to specify full scale design criteria. The testing was performed with four fuel types; No. 6 fuel oil, SRC fuel, SRC residual fuel oil, and SRC-water slurry. All fuels were precipitated quite easily resulting in emission rates below the NSPS standards.

The activity and aging rate of modified Shell 324 Ni-Mo-Al catalyst were studied in ICRC's process development unit (PDU) under SRC-I Demonstration Plant hydroprocessing conditions. The studies determined variations in SRC conversion, hydrocarbon gas production, hydrogen consumption, and heteroatom removal at both constant and increasing reaction temperatures. Samples of spent catalyst were analyzed to ascertain the reasons for catalyst deactivation. Finally, the PDU hydroprocessing results were compared with those generated at Lummus and Wilsonville pilot plants. 14 references, 25 figures, 16 tables.

Tests were performed to determine the feasibility of conveying Kerr-McGee ash concentrate from storage bins through the screw feeder to the Gesellschaft feur Kohle-Technologie (GKT) gasifier. A study comparing flow characteristics of coal, for which the GKT system was designed, and Kerr-McGee ash concentrate (KMAC) showed that properties were similar, although KMAC had a lower bulk density. A computer simulation based on these properties was then applied to the conveying system. Results showed that KMAC flow will be unstable for almost all the KMAC samples studied when the gradients in gas and solid contact pressure in the convergent outlet of the screw feeder are very large, and when the scale factor is relatively high, i.e., greater than the critical value of 460. However, use of larger bins coupled with operation of the screw feeder at a slower rpm should result in stable operation and satisfy the flow requirements of the process design. GKT concluded that while improvements can be made to boost throughput and increase stability, serious consideration should be given to an alternate pneumatic conveying system to the gasifier. 3 references, 4 figures, 4 tables.
