The chemical quality of surface runoff water from oil shale residue may be estimated by procedures developed within this report. This list of conclusions is necessarily incomplete until the water pollution potential of snowfall on spent oil shale residues has been determined.

Environmental Protection Agency.] -- Physical properties, including porosity, permeability, particle size distribution, and density of spent shale from three different retorting operations, have been determined.
In a study of the water pollution potential of spent oil-shale residues, the physical properties, including porosity, permeability, particle size distribution, and density of spent shale from 3 different retorting operations were determined.
Abstract. Disposal of massive amounts of spent shale will be required if an oil shale industry using surface retorting is developed. Field studies to model both low elevation (dry) and high elevation Water pollution potential of spent oil shale residues.
book disposal sites were initiated in on 2 types of spent oil shale; coarse textured-US Bureau of Mines (USBM) and fine-textured-the Oil Shale Corporation (TOSCO).
Oil shale gains attention as a potential abundant source of oil whenever the price of crude oil rises. disposal of vast quantities of spent rock. groundwater pollution. Among the water.
Retort residue ash of El-Lajjun oil shale from central Jordan has been studied for its cementitious and pozzolanic properties and potential uses in construction. During the preliminary phase, properties of the ash were determined and some tests were performed on pastes of ash, cement and their mixtures.
lems of air and water pollution. The most important factor that will determine the large-scale develop-ment of an oil-shale industry is the price of petroleum. Today, few if any, deposits of oil shale can be economically mined and processed for shale oil in competition with petroleum.
Nevertheless, some countries with oil-shale. The distilled vapors of oil, gas, and water are passed through a condenser cooled with ice water and then into a graduated centrifuge tube. The oil and water are separated by centrifuging.
The quantities reported are the weight percentages of shale oil (and its specific gravity), water, shale residue, and (by difference) gas plus losses. James G. Speight PhD, DSc, in Handbook of Industrial Hydrocarbon Processes, Oil shale is a fine-grained sedimentary rock containing relatively large amounts of organic matter (kerogen) from which significant amounts of shale oil and combustible gas can be extracted by destructive distillation.
Included in most definitions of oil shale, either stated or implied, is the potential for the. Oil Pollution in Water. Causes of Water Pollution. Oceans are polluted by oil on a daily basis from oil spills, routine shipping, run-offs and dumping.
Oil spills make up about 12% of the oil that enters the ocean. The rest come from shipping travel, drains and dumping. Adsorption, degradation, and movement are the key processes conditioning the behavior and fate of pesticides in the soil.
Six processes that can move pesticides are leaching, diffusion, volatilization, erosion and run-off, assimilation by microorganisms, and plant uptake. Leaching is the vertical downward displacement of pesticides through the soil profile and the unsaturated zone, and.
Environmental impact of the oil shale industry includes the consideration of issues such as land use, waste management, and water and air pollution caused by the extraction and processing of oil shale. Surface mining of oil shale deposits causes the usual environmental impacts of open-pit addition, the combustion and thermal processing generate waste material, which must be disposed.
Overview. Oil on Water is a novel by Helon Habila, who originally worked as a journalist and poet in Nigeria before becoming a professor of creative writing at George Mason. His writing has earned many accolades, including the Music Society of Nigeria national poetry award, the Caine Prize, the Commonweath Writers Prize, the Emily Balch Prize, and the Windham-Campbell.
Jordanian oil shale is generally of a good quality, with relatively low ash and moisture contents, a gross calorific value of MJ/kg, and an oil yield of 8 to 12%. The spent shale has residual. Few studies have addressed the impact of disposal of spent drilling fluids on soil-plant-water systems.
Some researchers found that high soluble salts, heavy metals, and petroleum residue contents in drilling fluids were detrimental to soil quality and plant growth (McFarland et al. ; Wojtanowicz ; Zvomuya et al. The surface water runoff from snowfall on oil shale residue has less water pollution potential than the runoff from rainfall.
The concentration of dissolved solids in the runoff was a function of the cummulative volume of runoff per unit width, the porosity of the oil shale retorting residue, the soil moisture content, the snowmelt rate, and.

1,° F (° C)) to obtain crude shale oil. Other products are the spent shale residue, pyrolysis gases,carbon dioxide, contami-nated water, and in some cases additional nahcolite and dawsonite ore. The crude shale oil may be sent to an upgrading section in which it is physically and chemically modified to improve its transportation.
Oil shale - Oil shale - Environmental issues: The production of oil from shales has a potentially serious impact on the environment.

Four specific areas of concern dominate discussion regarding development of the resource: greenhouse gas output, water consumption and pollution, surface disturbance, and socioeconomic effects. Because oil and gas are produced by heating oil shale and because. Oil shale gains attention as a potential abundant source of oil whenever the price of crude oil rises.
  At the same time, oil-shale mining and processing raise a number of environmental concerns, such as land use, waste disposal, water use, waste-water management, greenhouse-gas emissions and air pollution.
The wastes were produced under different conditions. Different analytical techniques (XRF, XRD, proximate analysis, infrared spectroscopy, particle size distribution, TGA/DSC, and ultimate analysis) were used to follow up the physicochemical changes in generated solid residues.
Oil shale was rich in carbonate with spent content of %. The pH change is ascribed to the oxidation of sulfides and polythionates, and the color change to the reduction of hexavalent molybdenum blue complex.
Major ions are not the only source of potential groundwater pollution from the oil shale residues. The spent shale also contains varying amounts of a great variety of trace elements.

The resulting picture is quite complex, as experimental results are affected by several factors, including: (1) the nature of the material under study (raw shale, spent shale, crude, hydro-treated or refined shale oil, retort process-water, or oil-shale ash); (2) the mineral composition of the original shale and the type of retort process; and.
Oil-shale lands that could be mined may be preempted by present land usage such as population centers, parks, and wildlife refuges. Development of new in-situ mining and processing technologies may allow an oil-shale operation in previously restricted areas without causing damage to the surface or posing problems of air and water pollution.
Industrial Pollution. Industrial pollution is the cause the most devastating ocean pollution events. Oil Spill is one of the most reason for the water of the more major spills in recent times include the Exxon Valdez oil spill in Prince William Sound, Alaska, in and the BP oil spill in the Gulf of Mexico in Compendium Reports on Oil Shale Technology, Volume 1 Compendium Reports on Oil Shale Technology, Environmental Monitoring and Support Laboratory (Las Vegas, Nev.)

Slawson, Teh Fu Yen: Contributors. Types and Sources of Water Pollution There are several major types of water pollution. One of the most destructive types is Petroleum Pollution.
Petroleum products, such as oil and gasoline, enter the water from ships and marine terminals, offshore oil rigs, runoff from parking lots, factories, oil dumping, and other sources. Marcellus Shale Water Pollution Risk Table I.
