Analysis of Paraho oil shale products and effluents: an example of the multi-technique approach

Inorganic analysis of solid, liquid and gaseous samples from the Paraho Semiworks Retort was completed using a multitechnique approach. The data were statistically analyzed to determine both the precision of each method and to see how closely the various techniques compared. The data were also used to determine the redistribution of 31 trace and major elements in the various effluents, including the offgas for the Paraho Retort operating in the direct mode. The computed mass balances show that approximately 1% or greater fractions of the As, Co, Hg, N, Ni, S and Se are released during retorting and redistributed to the product shale oil, retort water or product offgas. The fraction for these seven elements ranged from almost 1% for Co and Ni to 50 to 60% for Hg and N. Approximately 20% of the S and 5% of the As and Se are released. The mass balance redistribution during retorting for Al, Fe, Mg, V and Zn was observed to be no greater than .05%. These redistribution figures are generally in agreement with previous mass balance studies made for a limited number of elements on laboratory or smaller scale pilot retorts. 7 tables.

Phase I of the Near-Term Hybrid Vehicle Program. Final report (open access)

Phase I of the Near-Term Hybrid Vehicle Program. Final report

Heat engine/electric hybrid vehicles offer the potential of greatly reduced petroleum consumption, compared to conventional vehicles, without the disadvantages of limited performance and operating range associated with pure electric vehicles. This report documents a hybrid vehicle design approach which is aimed at the development of the technology required to achieve this potential, in such a way that it is transferable to the auto industry in the near term. The development of this design approach constituted Phase I of the Near-Term Hybrid Vehicle Program. The major tasks in this program were: mission analysis and performance specification studies; design tradeoff studies; and preliminary design. Detailed reports covering each of these tasks are included as appendices to this report. A fourth task, sensitivity studies, is also included in the report on the design tradeoff studies. Because of the detail with which these appendices cover methodology and results, the body of this report has been prepared as a brief executive summary of the program activities and results, with appropriate references to the detailed material in the appendices.

Klamath County YMCA geothermal heating project environmental assessment (open access)

Klamath County YMCA geothermal heating project environmental assessment

The YMCA Geothermal Heating project proposes to obtain approximately 57% of the total facility energy usage through direct application of the Klamath Falls KGRA. This will be accomplished through the design and construction of a retrofit and injection system for the utilization of an existing 110/sup 0/F geothermal energy source at the project site. The existing 2016 foot well will be outfitted with a turbine pump with variable speed drive. The well head will be enclosed by a 10' x 10' building. The geothermal fluid, pumped at a peak rate of 350 gpm will be transported to the YMCA Facility through 5'' diameter schedule 40 black iron pipe fitted with victaulic couplings for expansion. All underground supply pipes will be equipped with magnesium anodes for galvaic protection and will be insulted with 1'' thick calcium silicate insulation, with two layers of 45 number roofing felt applied with asphaltic compound. All supply lines within the building will be insulated with 1'' fiberglass insulation material with a cloth jacket. The fluids will pass through a heating coil and heat exchanger system to provide heat for the 30,000 square foot YMCA facility as well as for the 90,000 gallon swimming pool. The spent …

Demonstration salt gradient solar pond. Fourth semiannual progress report, November 1, 1978-June 30, 1979

A thorough account is given of a solar pond study underway at the University of New Mexico since 1975. This report consists of the Ph.D. dissertation of Federica Zangrando entitled Observation and Analysis of a Full-Scale Experimental Salt Gradient Solar Pond. The stability condition for a non-constant gradient, doubly-diffusive system is derived and a prescription for the routine detection of potential instabilities is presented. Techniques for handling unstable regions are described. Conclusions so far strongly support the viability of the solar pond concept. Salt gradient ponds appear to have a very definite niche in the ecology of energy production.

Arc--Coal Acetylene Process Development Program. Quarterly technical progress report No. 4, October 1--December 31, 1978

Data taken from the Avco 200 kw Arc Coal Reactor facility provides increasing optimism for this acetylene producing process. Continued improvements in the reactor design have been accomplished over the past three months. These improvements result in data which, when reduced and analyzed, yield SER's well below 5.0. Further, these SER values are an improvement over those of the comparable OCR program test data results under the same test conditions. The anode and cathode designed for this 200 kw Chemical Facilities have performed well with no visible degradation after minor adjustments in the geometry and operating procedures. The data taken to date, both with and without quench, within this facility underline the importance of commencing work on the 1 Mw Arc Coal Acetylene PDU where SER values between 3.5 and 4.0 are a clear probability. With values of SER in this range, the arc coal process is economically attractive as a competitor to the ethylene process for manufacturing vinyl chloride monomer and vinyl acetate monomer. A summary of the 200 kw facility test results in Appendix A is a synopsis of a Topical Technical Report submitted earlier.

Using surface waters for supplementing injection at the Salton Sea Geothermal Field (SSGF), Southern California (open access)

Using surface waters for supplementing injection at the Salton Sea Geothermal Field (SSGF), Southern California

The flash-steam conversion cycle is most suitable for electric power production at the SSGF. However, large-scale development of the SSGF may require use of makeup water supplements to injected brine for a viable reservoir pressure maintenance program. Since steam condensate will probably be required to satisfy power plant cooling needs, local surface waters have been evaluated for their potential use as sources of injection makeup. It was found that direct injection of untreated makeup water is not feasible because of high suspended solids loading and potential incompatability problems. However, mixtures of ambient temperature makeup water and higher temperature (80 to 90/sup 0/C) brine effluent, in a 1:4 mass ratio, are potentially injectable following processing by reaction clarification and granular media filtration.

Computer simulation of temperature-dependent equilibrium precipitation (open access)

Computer simulation of temperature-dependent equilibrium precipitation

The EQ3/EQ6 software package contains two computer codes (EQ3 and EQ6) and data files which form a useful tool in modeling precipitation from geothermal fluids caused by heating or cooling. The data files contain information on 140 aqueous species and nearly 150 minerals, and permit calculations over the temperature interval 0 to 350/sup 0/C. Assumption of homogeneous thermodynamic equilibrium in aqueous solution permits calculation of the driving forces for precipitation as measured by the affinity (log Q/K) for each such reaction. Further assumption of precipitation and heterogeneous equilibrium for any mineral whose affinity would otherwise exceed a value of zero permits determination of the identity of the precipitates, their masses and volumes, and the temperature ranges in which they form. The EQ3/EQ6 capability was used to determine the effects of temperature increase on formation of precipitates form Salton Sea water.

Low-Cost Solar Array Project. Task I. Silicon material: investigation of the hydrogenation of SiCl/sub 4/. Quarterly report

A laboratory stainless steel reactor has been constructed and installed to study the hydrogenation of SiCl/sub 4/, 3 SiCl/sub 4/ + 2 H/sub 2/ + Si in equilibrium 4 SiHCl/sub 3/. The pressure reactor is designed to operate at pressures up to 500 psig and at temperatures up to 600/sup 0/C. After pressure and leak tests, the apparatus was started-up for the hydrogenation experiments. Temperature and flowrate measurements were calibrated. A safety review showed that the apparatus functioned smoothly and satisfactorily as designed. Experiments on the hydrogenation of SiCl/sub 4/ were carrried out during the last two weeks of September. A series of experiments on the hydrogenation of SiCl/sub 4/ was carried out at reactor pressure of 300 psig and 500 psig. Reaction temperature varies from 450/sup 0/C to 550/sup 0/C. Some preliminary reaction kinetic data and equilibrium data were collected. More hydrogenation experiments are in progress.

Aspects of nuclear waste management. Volume 1. Pre-emplacement risks

Results of the previous one-dimensional thermal analysis of interim storage accidents are confirmed by more detailed two-dimensional calculations. Waste temperatures calculated for interim storage accidents are moderately sensitive to assumptions concerning canister spacing and are much less sensitive to boundary conditions at the canister top. For an individual 100 m from a transportation accident involving solidified high-level waste, the expected dose from gamma radiation is on the order of or smaller than the other possible exposures in the same accident. For the calculation of expected doses to the worst-situated individual in accidents: Expected population dose should remain the primary measure of pre-emplacement risk in order to maintain comparability of consequences of different types of accidents.
